PAE 25 air cooler

Elegant design paired with efficient technology

Enjoy natural cooling and a breath of fresh air

The PAE 25 air cooler does climate miracles – in a double sense. It lowers the room temperature to a comfortable degree. Yet there is no need to use chemical refrigerants or carry out complicated installation work as is the case with conventional air conditioners. There are no limitations as to where to set up the device. You do not have to install an exhaust air hose on doors or windows, such as is required for mobile air conditioning systems.

This air cooler simply makes use of the latent heat of evaporation of its ice or cold water filling to cool down the incoming warm air and blow out the now cold air via the fan. It means immediate refreshment when the air cooler produces a pleasant as well as energy-saving feel-good climate in medium-sized rooms because at an air flow rate of 320 m³/h, power consumption is as low as 65 watts. Operating costs are thus extremely low.

However, the PAE 25 can be used as proper fan without the air cooling function being activated. The fan power can be adjusted in three stages. The horizontal discharge direction can be flexibly set by means of the ventilation flaps. In order to distribute the cooling air current throughout the room, you can activate the additional swing mode function of the vertical air flaps. The integrated natural wind mode gently rises and diminishes the air current which creates the impression of a pleasant sea breeze. The easily removable air filter absorbs pieces of dust, fluff and animal hair from the room air.

Humidifier preventing dry heated air and the multiplication of viruses

As an efficient humidifier, the PAE 25 provides for a feel-good climate in the cold season. The room air, which is often too dry during the heating period is optimally humidified, preventing the mucous membranes of your nose, mouth and throat from being dried out as quickly. Moreover, the distribution of viruses and bacteria in the room air is reduced at a humidity level of 50 %. This helps you to substantially minimize the risk of catching a cold or a viral disease of the respiratory tract!

Increasing the humidity level to 50 % reduces the risk of transmission of viruses

Medical specialists have evaluated research findings relating to the resistance of viruses (e.g. SARS-CoV, MERS-CoV or SARS-CoV-2 (Covid-19), influenza) to air humidity. These findings have revealed that the humidity level has a crucial impact on the infectivity of germ droplets. Dry room air with a relative humidity content of less than 40 % lets tiny droplets infected with influenza or cold viruses dry up. This preserves pathogens so that they remain infectious for a very long time. In the optimum relative humidity range between 40 and 60 % aerosols only shrink so far that the salt concentration in the aerosol core increases, causing the germs and microorganisms contained to be killed. This minimizes the risk of an infection with influenza and cold viruses.

Medical specialists emphasize that we are able to reduce the risk of infection by increasing the humidity level in buildings. In this way, increasing the humidity level to approx. 50 % by humidification will reduce the risk of transmission. Moreover, the humidified air improves the body's defence situation by more efficient cleaning of the air passages and an improved immune defence. In modern buildings with a watertight building envelope, central heating and ventilation systems, these limit values can often not be complied with in everyday life without active humidification. This is where devices with a humidification function come in to provide assistance.

Comfort is major priority

Apart from cooling, the air cooler can also be used for air freshening: The built-in air filter and the ingenious honeycomb structure of the evaporation filter allow to first filter the sucked-in air and then to humidify it and feed it back to the room as cooled air.

The PAE 25 thus also works as a fan for humidifying and cleaning air. Four ventilation speeds offer further options to achieve the ideal feel-good climate. The adjustable discharge direction and the optional automatic swing mode provide for an even better distribution of cool room air. While you are asleep, you can have the air cooler in ultra-silent night mode. These functions can be set via the remote control or directly on the device.

The PAE 25 air cooler is very compact and easy to transport. It has four floor rollers and the practical attached handle and can be used almost anywhere indoors — just wherever you happen to need a cool breeze.

The large 4.5-litre water tank allows long cooling and humidification times. During operation, the device requires hardly any attention because the water consumption of about 1 litre per hour is very low. In the course of one day in the office, for example, the water has to be refilled only once.

Timer function

The practical 8-hour timer allows to switch the device off individually after a preset time. In this way you ensure that, for example in the office, the air cooler will switch off automatically when office hours are over.

Night mode

To ensure that you can go to sleep and have a good night's rest, the air cooler is provided with a night mode and an ultra-silent operation. In this way you go to sleep with a pleasant air cooling and your body will refresh optimally from the struggles of the day even in the hottest summer nights. Tip: If required, the timer can be additionally used to switch off the device automatically during the night.

Our recommendation:

Fill cool water into the evaporative air cooler.
For an extra-cool breeze, use the ice packs included in the scope of delivery or add ice cubes to the water!

Natural cooling principle

In contrast to air conditioners, air coolers do not use any chemical refrigerants. The cooling effect is generated in a natural manner. Moreover, neither an exhaust air hose nor any elaborate installations are required.

A mobile air cooler works on the principle of natural evaporation cooling. As you probably know from your own experience, blowing on moist skin creates an instant feeling of refreshment as the evaporation process withdraws warmth. Air coolers work in the same way: in the interior of the air cooler there is a water-soaked filter mat using. The warm air is directed from the rear of the device through the wet filter mat and in passing is cooled down due to the evaporation effect. The now colder air is then blown back into the room by the fan.

Can be operated all year round – air cooler in the summer, humidifier in the winter

With the PAE 51 you can enjoy mobile feel-good climate throughout the year. We recommend using the slim air cooler in space-saving design throughout the year rather than parking it in a storeroom when the summer ends. In the spring and late summer its 4 fan stages can provide a fresh breeze so that you can enjoy the cooling effect of the cold evaporation.

In autumn and winter the device is furthermore well-suited as an effective humidifier, in order to create a more pleasant room climate. Since dry heated air can irritate the respiratory tract, dry out the skin and cause red eyes. Moreover, the multiplication of viruses within the room air is reduced at a humidity level of 50 %. By using a humidifier you provide for a sufficient humidity level and in this way can improve your own well-being in sticky, overheated rooms as well as prevent colds and virus infections.

With the 4-in-1 air cooler PAE 25 you benefit from pleasant air cooling, refreshing ventilation and agreeable humidification. For a perfect climate throughout the year!


Continuous fresh water supply to ensure a healthy air quality.

To automatically keep the water storage tank as clean as on the first day, we recommend using a SecoSan-Stick which keeps the water permanently clean, clear and free from germs or unpleasant odours. The unique feature of SecoSan is its antimicrobial surface with mobile silver ions, which inhibit bacteria and germs upon contact and thus prevent their reproduction. The entirely self-dosing SecoSan ion reservoir keeps the water demonstrably free from germs. The stick thus guarantees clean water for up to 6 months even if the water is changed or consumed daily.

Thermohygrometer BZ20M with air cooler PAE 29

Using air coolers as humidifiers during the wintertime

Air coolers are most efficient in rooms filled with dry air. Just like humidifiers these devices operate based on the evaporation principle, i.e. they directly supply the air with cool moisture. This means that for process-related reasons the humidity level in the room is increased perceptibly. During the winter this increase of humidity is beneficial to the mucous membranes. As a result you might be able to avoid catching a cold that is largely caused by the dry heated air. The practical and optically attractive thermohygrometer BZ20M in cross-needle design shows you at a glance when the humidity level is in the optimum range.
