Virus-free room air in schools and educational facilities

Trotec high-frequency air cleaners maintain the room air in classrooms reliably free from viruses with H14 high-performance filters

A sustainable new start of regular school life makes a hygiene concept that is shown to be effective indispensable to provide for virus-free air in classrooms. The coronavirus SARS CoV-2 is a huge challenge for teaching staff, cleaning staff and headmasters. Even using spraying and wiping agents in a regular manner does not provide any protection against this virus which not so much spreads by smear and droplet infection, but rather directly via the room air. The protection of pupils and teaching staff therefore requires measures that are demonstrably effective, in order to reliably reduce the airborne infection risk.

Classrooms require virus-free ambient conditions

Ensuring safe presence at school requires guaranteed virus absence

Real face-to-face teaching requires personal closeness, immediate feedback via gestures, behaviour, questions and answers. Therefore, teachers can actually not do without the direct contact on site in order to perform their educational task in a realistic fashion.

However, this direct contact always carries the risk of an infection with airborne diseases. In best case, this could be flue, in times of corona it could be Covid-19. Not only since Corona times it has been highly recommended to take additional hygiene measures in addition to the regular ones: The air in the room and particularly the air for breathing must be kept as clean as possible and free from viruses or bacteria. This serves to protect the teaching staff, but also the pupils.

Clean air in the classroom protects teachers and students

Pathogenic viruses and bacteria are an invisible danger in every school. The pathogens can survive in the room air for several hours, presenting a potential health risk with every breath. Current studies prove that e.g. the Sars-CoV-2 virus can stay in the air for several hours while remaining infective.

The virus gets into the room air by means of aerosols that are emitted when breathing and speaking. Infectious viruses adhere to these tiny particles and the virus-carrying aerosols waft through the air due to their light weight and are inhaled unnoticed by other persons in the same schoolroom, for instance by fellow pupils or teachers.

Dividing school classes into two groups does not offer protection against virus-laden air

It is an elementary component of hygiene concepts to reduce class sizes in times of spreading epidemics. But no matter how small the groups are into which the pupils are divided: it does not prevent the virus from spreading through the air. Even using protective masks for mouth and nose does not entirely offer protection against direct ‘virus drizzle rain’ caused by “juicy” talking. Protective masks definitely do not offer protection from germ-loaded aerosols that are released into the room air while talking and breathing, where they will continue floating in the form of aerosol accumulations for several hours.

Any person talking loudly is sufficient to have thousands of aerosols spreading into the room air per minute. The number even increases when care workers and children sing. Indeed, protective masks are a first important approach to reduce the risk of a direct droplet infection with the SARS-CoV-2 virus. However, this measure does not protect from a far greater danger of infection – accumulations of aerosol particles floating freely in the room air!

Such aerosol clouds even overcome physical barriers like sneeze guard barriers or separating walls. This is how particles of aerosol can easily access the respiratory tract or the eyes. The long time aerosols stay in the air are the reason for another problem: Since aerosols spread with air currents, the room air will be mixed every time the door is opened.

Protecting teachers and pupils with a 360-degree hygiene concept

Only a coordinated all-round solution of all possible hygiene measures and additional high frequency air purification reliably and permanently reduces the risk of infection. So don’t exclusively rely on physical separation, protective masks and washing hands regularly for protection against infections. Aerosol particles in the room air don't stick to the distance rules – as they potentially transport viruses, they are the real source of danger!


High-performance air purification creates virus-free air in classrooms

If the room air is kept free from germs and viruses, the airborne risk of infection will be minimised likewise. Trotec high-frequency air cleaners such as the TAC V+ are exactly designed to perform this task, for they efficiently and quickly reduce the intensity and time aerosol accumulations and suspended matter stay in closed rooms, creating an education facility with an extraordinarily reduced risk of infection for both teachers and pupils.

Directly at its site of installation, the mobile air cleaner TAC V+ creates a “Clean air zone”, flooded with purified air and filtered from viruses. Within this zone, the surrounding air nearly completely stays free of airborne germs and viruses because the TAC V+ is able to take in large volumes of contaminated room air and to carry out effective H14 HEPA high-performance air filtration. Moreover, the device is able to purify room air zones in a flexibly adjustable manner with clean air that has been filtered from viruses and aerosol particles.

Effective against bacteria and virus accumulations

Trotec high-frequency air cleaners are equipped with HEPA high-performance air filters of class H14 which filter out more than 99.995 % of all fine suspended particles larger than 0.1 µm with a transmittance of only 0.005 %. Or in other words: No more than five of 100,000 particles pass the H14 filter. Thanks to this unique feature, these kinds of high-performance filters are also used in operation theatres or comparable hygienically sensitive areas in order to produce clean air. In this way, you create optimum conditions to keep the room air and breathing air in classrooms, staff rooms, school administration areas, break rooms, halls and foyers free from germs and viruses in times of spreading epidemics.

Well-known viral strains such as SARS-CoV, MERS-CoV or Covid-19 have a particle size of 0.005 to 0.1 µm. Most of the time, they form accumulations with other particles (such as saliva or suspended matter) which increases their size up to 0.4 µm or 0.5 µm. These accumulations are referred to as germs and will be filtered out reliably by the Trotec H14 air cleaning filters.

All H14 HEPA high-performance air filters from Trotec meet the highest quality standards that are obligatory for bacteria and virus filtration.

  • Each H14 high-performance air filter is tested individually and is assigned its respective serial number
  • The test report is enclosed as certificate in duplicate with each H14 high-performance air filter
  • The original test certificate can be filed with the documents for the device. If required, the copy can be attached to the air cleaning device.
  • HEPA H14 high-performance air filters are tested in compliance with EN 1822 and EN 60335-2-69.

Also suitable for any TAC air cleaner with H13 filter

You can also insert a HEPA H14 high-performance air filter from Trotec into your TAC air cleaner if you already possess a TAC device. The H14 filters are available as an accessory, e.g. for the professional air cleaners TAC 3000, TAC 5000 or TAC 6500. Simply replace the H13 filter in the filter compartment with a H14 HEPA high-performance air filter.

Virus-filtered clean air in music schools or at choir rehearsals

Apart from its use in public or private schools, the TAC V+ is also ideally suited for virus filtration in other educational facilities like for example music schools

Music lesson or choir rehearsal – the TAC V+ creates filtered room air that is free from viruses

The transfer of knowledge in schools requires room for personal proximity to teach and learn. This principle applies to primary and secondary schools as well as to music schools or other educational facilities. When not required for lessons, school rooms are often made available to specific associations like for example choirs to hold their choir rehearsals.

The TAC V+ is also the ideal air purification solution for such school events, in order to provide for aerosol-free room air without aerosols carrying viruses and thus without a corresponding infection risk. The high-frequency air air cleaner TAC V+ draws in the ambient air near the floor and leads it through an effectively attuned filter system. The last filter stage of the latter is a unique H14 high-temperature lamellae particulate air filter with thermal filter decontamination. This H14 HEPA filter is treated thermally at regular intervals and heated to over 100 °C, which practically destroys all viruses that are filtered out. Therefore infectious viruses can no longer enter the ambient air from the filter. Instead, the TAC V+ only blows virus-free, filtered clean air back to the room in a draught-free fashion via its specially formed blow-out tower!

In particular for musical activities and especially when singing together, the use of the TAC V+ can be an effective prophylactic measure against the spreading of aerosols carrying viruses. Since singing transports aerosols into the room via the breath in an especially wide radius and can float there in the room air for several hours. The louder the singing, the wider the spreading radius.

Only the high-frequency air cleaner TAC V+ is able to effectively and quickly reduce the dwell time and intensity of aerosol and particle accumulations carrying viruses in closed rooms and in this way create a safe environment with a substantially reduced risk of infection for teachers, music students or choir members. The virucidal effectiveness of the TAC V+ has been scientifically proven!

Our recommendation for virus filtration in schools and other educational facilities

The Trotec high-frequency air purifier TAC V+ with H14 high-performance filtration

The TAC V+ takes in the virus-infected air, filtering it with the HEPA technology whereupon they transmit it back to the room air

The vertical construction of the mobile high-frequency air cleaner TAC V+ serves for establishing particularly efficient “Clean air zones” with surrounding air filtered from viruses. Setting up several devices with some distance in-between will create clean air environments with a low aerosol concentration for classrooms, school break areas, or areas for study periods. Moreover, the mobile TAC V+ can be repositioned in no time, making it possible to utilize it flexibly for a variety of rooms.

High-frequency air purification eradicates accumulations of aerosol particles in minutes

By deliberately positioning several high-frequency air cleaners of type TAC V+ or TES 200, pupils and teachers will be way better protected from suddenly appearing droplets and accumulations of aerosol particles. These will be filtered out within the shortest time due to the high air change rate. Besides, areas will be permanently filled with large amounts of virus-free room air which will significantly reduce the risk of infection in the “Clean air zone”.

Special H14 high-performance air filter with thermal self-regeneration function

This air cleaning performance is made possible by a synchronous system of efficient prefiltering and final particulate air filtration, provided by the integrated H14 high-performance air filter in compliance with EN 1822 (ISO 45H filter ISO 29463) by Trotec in a special heat-resistant version. This special filter is integrated in the devices TAC V+ and TES 200 and is heated up in intervals which will inactivate all viruses remaining in the filter, serving for a 100 % decontamination of the filter. The thermal self-regeneration function of the special H14 high-performance air filter is unique in the world and exclusively available at Trotec!

TAC V+ and TES 200 are part of the same assembly and therefore provide the identical fan performance and HEPA air purification function. The TES 200 can, however, also be used for combined room heating, thermal decontamination of rooms and surfaces and thermal pest control. The reason for this are the additionally integrated, powerful electric heating module and enhanced programming options for various air treatment scenarios.

Thanks to their combined technology of filter and decontamination techniques which are unique in the world, TAC V+ and TES 200 provide safety by reducing the risk of an airborne infection in all areas with a lot of public traffic – ideally suited for schools and other educational facilities.
Example of use in a large classroom: With an area of 9 x 7 m and a room height of 3 m the depicted classroom has an air volume of 189 m³. Our recommendation: two TAC V+ placed in the room, set to a ventilation performance of 800 m³/h each reach a total ventilation performance of 1,600 m³/h and thus attain an air change rate (ACH) >8. In the case of a higher safety requirement, the device setting can be increased to a ventilation performance of 1,000 m³/h in each case, ensuring a total ventilation performance of 2,000 m³/h and thus an air change rate (ACH) of >10.

Our recommendation: a centrally placed TAC V+ set to a ventilation performance of 800 m³/h, allows for an air change rate (ACH) of approx. 8. In the case of a higher safety requirement, the device setting can be increased to a ventilation performance of 1,000 m³/h, ensuring an air change rate (ACH) of almost 10.
TAC V+ in a small classroom – installation example 3

This is how you achieve maximum protection against an indirect infection:

The better the optimum airflow, the larger the room volume and the higher the air circulation and therefore the circulation rate, the lower is the concentration of aerosols in the room air, which also reduces the risk of infection.

The number of air circulations at the same time determines the operating range of each individual high-performance air cleaner and thus also determines the safety level within the room.

Since even with an increased circulation rate, room air can never achieve a completely virus-free state if the room contains infected persons – you can merely establish a mixture of filtered air and permanently generated virus-carrying aerosols.

Therefore the following applies: The higher the circulation rate and the more filtered air per person is generated, the more the virus concentration in the room air is diluted. This results in a decreasing risk of indirect infections.

Air change recommendations for different rooms

Why commercially available HEPA air cleaners are not sufficient for virus filtration in most cases

Large clean air capacity – high-performance filtration – filter decontamination – filter regeneration – noise level in the case of a large air volume – versatility

Well thought out to a detailed level, unparalleled in its entirety: With these 6 plus points, the TAC V+ – as is scientifically proven in several studies – ensures a technically effective and economically attractive solution to reduce the risk of infection by aerosols in closed rooms.


Large clean air capacity, high flow pressure and an optimum flow geometry

Only the TAC V+ has "the power to quickly dilute the room air"

Time is the most important factor when it comes to reducing the risk of an indirect infection. And we're talking about the shortest time possible for quickly and effectively diluting the infectious aerosol accumulations that are for example generated by a super-spreader, directly at their source. This requires large volumes of clean air and a high fan performance to establish an optimized flow geometry.

All this is provided by the TAC V+: With a large clean air volume, an optimum flow geometry and a flow pressure that is more than high enough, circulation is established in the room within a very short time, ensuring that all the contaminated room air is diluted and effectively filtered within only a few minutes.

Only circulation rates that are sufficiently high minimize the risk of infection, this is scientifically proven. Where the effective treatment of the risks of infection by aerosol particles is concerned, a high air circulation rate (at least a factor of 6 or even more, if possible) and therefore a large volume of cleaned air are indispensable, despite promises to the contrary made by other providers advertising single to threefold air change rates per hour as sufficient.

As is proven by scientific studies, effective virus filtration requires a sufficiently dimensioned volumetric flow so as to ensure that the air cleaner can provide for the number of air changes required as is guaranteed by the TAC V+. In this context, "air change" does not refer to a complete exchange of the air, but to the proportion of virus-filtered clean air that is supplied, relating to the room volume per hour.

FlowMatic ensures constant air circulation rates even with increasing filter pollution

In order to comply with the circulation rate required by the hygiene concept, a constant volumetric flow throughout the whole operating lifetime is indispensable. However, the filter elements of every air cleaner are successively clogged over time by coarse and fine dust (e.g. caused by traffic load). This leads to an increasing counter-pressure combined with a strongly decreasing air flow rate, inevitably reducing the level of protection envisaged.

With the innovative FlowMatic control of the TAC V+ You no longer have to worry about a decreasing volumetric flow or circulation rates that fall below the values required.

Just like with the cruise control of your car, the FlowMatic sensors capture the actual air flow rate values within the entire filter ladder and consecutively adapt the system performance dynamically. In this way, the air volume target value once preset remains constant in every situation! This not only increases the filter lifetime and system efficiency, but also guarantees compliance with the circulation rate required by the corresponding hygiene concept.

Air cleaners without a FlowMatic control are unlikely to constantly and reliably meet the requirements so as to comply with the circulation rate required.

High-performance filtration: H14 means maximum HEPA filter efficiency

The TAC V+ can "effectively separate" viruses

Heat-resistant H14 HEPA high-performance filter

Exclusively H14-HEPA high-performance filters complying with EN 1822 specifications (ISO 45H filter ISO 29463) like they are used in the TAC V+ are able to even filter the tiny virus-infected aerosol particles (0.1 - 0.2 µm) from the room air, and this at a percentage of 99.995 %. Therefore the filter efficiency of H14 HEPA filters complying with EN 1822 is 10 times higher than that of H13 HEPA filters with 99.95 %, as used in most air cleaners!

99.995 % or 99.95 %? This may not sound like a lot, but exactly these two decimal places make the big difference between H13 and H14 HEPA filters! Virus-carrying aerosol particles are extremely tiny. And "virus filters" are designed to "filter viruses". That's why the TAC V+ not only filters the large, but also the small-sized, highly infectious aerosols from the room air not even filtered out by FFP2 and FFP3 respiratory masks, which therefore don't offer genuine protection. Real safety is exclusively provided by an H14 HEPA filter (EN 1822)!

Scientific studies, however, qualify that a filter performance beneficial to the decay rate pursued can only be confirmed if the volume flow of the air cleaner and the flow speed in the particulate air filter are sufficiently attuned to one another by an adequately dimensioned filter surface, a property which at present cannot be achieved with any other mobile air cleaner than the TAC V+!

Thermal filter decontamination – your safety airbag

Unique technology – Trotec exclusive

The thermography image illustrates this: In the process of thermal decontamination the heat-resistant H14 virus filter of the TAC V+ is heated to approx. 100 °C, destroying all bound viruses and bacteria.
Fully encapsulated H14 high-temperature particulate air filter, equipped with heat-conducting metal lamellae

Only with the TAC V+ and TES 200 the special, fully encapsulated H14 high-temperature lamellae high-efficiency particulate air filter is treated thermally and heated to approx. 100 °C at regular intervals. Explicitly for this purpose, this filter has been developed and interspersed with special, heat conducting metal fins.

This thermal filter decontamination technology is available exclusively at Trotec and offers you several unique benefits at the same time! By heating the filters, the proteins of the viruses filtered out, which are relevant to the infectiousness, are denatured, and the viruses are practically destroyed. Therefore infectious viruses can no longer enter the ambient air from the filter, for example by improper handling Furthermore, bacteria, germs and other microorganisms are additionally destroyed.

All this means that 100 % employee protection can be ensured during operation and also when the filter is changed! You could say, it's the "virus airbag" that provides for more safety. It is there when you need it – and as long as nothing happens, you won't even notice it.

Scientific studies substantiate the mandatory prerequisite of thermal filter decontamination to ensure effective virus filtration. In fact, Professor Christian Kähler explicitly points out this mandatory provision in his study: "To ensure a maximum degree of hygiene and a longer lifetime in continuous operation, the H14 filter should be heated to approx. 100 °C every day for about 15 minutes, in order to destroy the viruses in the filter and prevent the formation of biofilms, bacteria and fungi without using harmful chemical additives or UV-C radiation."

Thermal filter regeneration – for optimum filter hygiene and a prolonged filter lifetime

No filter humidity, no filter mould or odour, and at the same time a much longer filter lifetime

Thermal filter decontamination and thermal filter regeneration

Aerosol separators and virus air cleaners take effect where many people are present in narrow spaces over a longer time and exhale larger quantities of aerosols. Aerosols, whether virus-carrying or not, for the greater part consist of micro droplets – pure water, that is. Customary H14 filters may be able to "catch" these humid aerosols, however, they also catch additional problems. Since the increasing humidity in the filter causes it to start fouling more quickly. As a result, the filter resistance increases, constantly reducing the clean air volume emitted and thus significantly reducing the filter lifetime. The fast fouling of filters at high loads of aerosols has been scientifically proven by field tests.

Moreover, the constantly high level of humidity favours the formation of filter mould or biofilms. Instead of eliminating a hazard, others may therefore be created. For example, a decreasing flow rate, shorter filter lifetimes and mould on the filter. But since the filter is heated to more than 100 °C at regular intervals, the ingress of moisture, fast sooting and filter mould are not a problem with the TAC V+. Since the humidity is fully discharged again in the course of the thermal regeneration cycle, not only drying the filter at regular intervals, but additionally regenerating it again via its self-cleaning function.

With this innovative procedure the filter resistance remains low and the clean air flow remains at a constantly high level for a considerably longer time. Consequently the lifetime is much longer than that of other filter systems without thermal regeneration and decontamination. This is also confirmed by current studies, which sum up as follows in the context of an examination of the TAC V+ and its H14 filter which complies with the specifications of EN 1822 (ISO 45H filter ISO 29463) and which features a self-cleaning function: "Therefore it is to be expected that this filter can have a lifetime of several years, depending on the load."

Low-noise: Hard to believe, hardly to be heard

The TAC V+ is an an air cleaning revolution of the silent kind

Sound protection hood to ensure silent operation

The task of qualified high-performance air purifiers is to make the utilization of interior spaces possible again – and not to make it more difficult! Nevertheless, without large volumes of clean air, the risk of infection cannot be minimized!

When aerosol particles are separated or viruses and bacteria are filtered out, high air circulation rates between 6 and 8 per hour are required, and in the medical sector even 12- to 15-fold air circulation rates per hour. Without these large air circulation rates, spontaneously occurring aerosol clouds cannot be reliably and quickly diluted and filtered out.

Therefore, even in smaller rooms of 45 m² you already need amounts of clean air from 700 m³ to 1,500 m³, which requires a fan with a correspondingly high ventilation power. In particular to establish an optimum air flow and air routing in the room. In addition to the flow geometry, filter efficiency and long filter lifetimes, however, an acceptable noise level, in spite of the large air volumes and the high fan performance, is desirable.

This is why one of the top priorities in the design of the TAC V+ was a low noise emission

For noise sensitive areas such as schools, offices or medical practices we recommend using the optional sound protection hood by means of which the sound level experienced subjectively can be again reduced by more than 50 %! In workshops, packing stations or discotheques, etc. the use of the sound protection hood usually is not required.

With an optional H14-Ultra-Highflow filter and an installed sound protection hood, the TAC V+ for example merely generates approx. 45 dB at level 3 with a clean air flow rate of 1,000 m³/h. For comparison: A customary laser printer already generates a sound level of approx. 50 dB during operation.

Stable design, flexible installation Virus protection on the spot

The TAC V+ is flexible, mobile and can be used everywhere at any time

The extremely stable, robust and scratch-resistant metal housing was specially designed for the use in environments where many people come together, work, play, learn or celebrate. This makes it possible to use the TAC V+ everywhere it's needed without any installation effort.

Flexible, mobile and modular – the exact number of TAC V+ devices required by the hygiene concept can be provided in each case. Variably adapted to the staff density, security level, type of application, background noise, room size and room geometry. The optionally available hose adapter makes it possible to also connect the TAC V+ to existing air distribution systems.

Where the effective control of infection risks due to aerosol particles is concerned, high circulation rates and therefore large and flexibly adjustable volumes of clean air are indispensable, despite promises to the contrary made by other providers who advertise single to threefold circulation rates per hour as sufficient.

To meet these requirements, the virus air cleaner not only has to be able to provide corresponding volumes of clean air, but it must also be flexibly placeable directly in potential hazard zones to ensure effective air routing. The TAC V+ is also optionally available in a tamper-proof version for the use in schools or daycare centres.

Scientifically proven: Only sufficiently high air change rates and proper positioning of the devices with respect to the air flow and routing provide a sufficient level of protection against an infection risk.


Well thought out to the detail, unparalleled in its entirety – the six benefits of the TAC V+ at a glance:

  1. Large clean air capacity: Up to 2,400 m³/h of virus-filtered clean air with a high flow pressure for optimum air circulation and high air circulation rates

Triple indicator for healthy room air: Our BQ air quality measuring devices indicate all important values

Particle measuring device BQ30 for air quality monitoring

The Air quality monitor BQ30 should not be missing on any teacher's desk or in any open-plan office because this environmental monitoring station shows you the most important values for healthy room air at a glance: In addition to the current CO2 load and the prevailing climate data and the particulate matter pollution in particle size PM2.5 or PM10 are shown to you.

The CO2 pollution is an important indicator of required ventilation measures and the fine dust particle sizes determined also include pollen, a helpful feature to monitor the air quality for allergy sufferers! In rooms with a large number of persons, CO2 Traffic lights can serve as a means for rough-orientation to indicate whether the air quality is good or poor, as carbon dioxide (CO2) is a reliable indicator of an air change.

In addition to the BQ30 Trotec's range of products includes further professional particle counters such as the PC200 or the PC220. Our particle counters cannot only be used for inspecting the air quality, but to test filter systems as well, for example.

Note: Neither the degree of air pollution caused by particulate matter of the particle size PM2.5 nor the CO2 pollution in the room tells you anything about the infection risk! None of the two values are a measurand of the risk of infection, since there is no correlation between CO2 or PM2.5 concentration and viral load.
