Air cooler PAE 40

Quick cooling and freshness with humidified and clean room air: 4-in-1 evaporation air cooler with remote control

Icy wind for hot summer days

The chic air cooler PAE 40 with convenient remote control is a true all-rounder. On hot summer days, the elegantly white comfort device rapidly cools down heated rooms, provides soothing freshness or icy coldness on the skin and additionally humidifies the room air. Furthermore, the air is purified in the integrated air filter and, if desired, by on-demand ionization to eliminate unpleasant odours and pollutants, such as bacteria, from the room air. Optimum conditions for a healthy feel-good indoor climate, even when the sun is blazing outside.

Natural evaporation cooling – without chemicals or exhaust air hoses

Unlike conventional air conditioners, the air cooler PAE 40 does not need any chemical cooling agents. Nor does the device require an unsightly exhaust air hose, which discharges the warm air to the outside in mobile air conditioners. Instead, the compact cooling giant makes use of the latent heat of natural evaporation of its ice or cold water filling to cool down the heated room air and blow it out into the room as fresh cold air via the fan. With its impressive air flow rate of 370 m³/h and a generous 10-litre water tank, the air cooler is recommended for use in rooms sized up to 36 m² or 90 m³.

Cooling and humidification with additional health protection

With the immediately noticeable cooling effect, the application possibilities of the modern air cooler are by no means exhausted. With the PAE 40 you can rely on permanent health protection against airborne viruses. The proliferation of viruses (for example flu viruses, coronaviruses, etc.) is strongly influenced by the humidity of the air. Optimally humidified room air has been proven to reduce the risk of infection in closed rooms and additionally keeps the nasal mucous membranes, which are important for the immune defence, moist. As a humidifier for year-round use, the PAE 40 impresses with a humidification performance of 1.1 l/h, which is enough to keep the room humidity level in different living and working spaces in the optimum range of 40–60 %.

With the air cooling and humidification function deactivated, the PAE 40 can be used as a fully-fledged fan. To distribute the cool air over a large area in the entire room or concentrate it on a specific point as desired, the discharge direction of the four-stage adjustable fan can be set via the front ventilation flaps either manually or using the automatic swing function. Thanks to the optional on-demand swing function with vertical oscillation of the inner fins, the discharge direction can be additionally controlled. The high degree of functionality of the PAE 40 is completed by a sleep-promoting night mode with noise-reduced ventilation and an easy-to-programme 15-hour timer for automatic device switch-off.

With the air cooler PAE 40, you can keep cool in summer, ensure optimally humidified rooms in winter and create a healthy indoor climate in your own four walls all year round.

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.

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

Noticeably more comfort with nothing to hide

Whether as an air cooler to quickly counteract hot temperatures, as an effective air cleaner generating purified air, as a fan for pleasant refreshment or as an air freshener to generate a natural wind current – the air cooler PAE 40 convinces in every operating mode with powerful performance values and comfort features unrivalled in this device class.

Double air purification through integrated air filter and ionization

An important contribution to health protection: the on-demand ionization function emits ions into the room air, which are completely harmless to health. By means of the ions released, viruses, bacteria, pollen, dust and odours in the air are reduced. The air pollutants and floating particles attach to the electrically charged ions and are bound. In addition, the integrated air filter removes dust, fluff and animal hair from the room air. The fine nylon mesh filter can be washed.

Automatic swing function – horizontal and vertical

To ensure optimum air circulation in the room, the discharge direction of the four-stage adjustable fan can be set via the front ventilation flaps using the automatic swing function. Thanks to the optional on-demand swing function with vertical oscillation of the inner fins, the discharge direction can be additionally controlled.

Timer function for energy-saving auto switch-off

Don't worry about unnecessary electricity costs – the PAE 40 thinks for itself. The easily programmable timer allows the device to switch off fully automatically after an individually preset time. The operating time until auto switch-off can be preselected from 1 to 15 hours in increments of 1 hour. The timer function is particularly convenient when the device is used in the bedroom, so it will switch off fully automatically after you have been lulled to sleep by a cool breeze.

Night mode for a refreshing sleep
and pleasant air freshening function

If you don't want to do without the cooling wind effect of the PAE 40 during sleep, we recommend activating the night mode with gradual reduction of the fan speed. First, the air cooler starts cooling with the preset fan stage to send you to sleep with a fresh breeze. Afterwards, the device automatically switches to the night programme with an air flow rate adapted to sleep requirements. It is also worth using the PAE 40 in the bedroom in the cold winter months, for thanks to its humidification function, dry heated air does not stand a chance. This has a beneficial effect on sleep.
Like a natural wind mode, the air freshening function provides a pleasant air flow comparable to a sea breeze by alternately increasing and reducing the ventilation intensity.

Natural cooling principle

In contrast to air conditioners air coolers do not make use of any chemical cooling agents. 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. 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.

Tip for refreshment: The colder the water, the greater the cooling capacity. Placing the two ice packs included in the scope of delivery into the water tank will further increase the cooling capacity. This additional boost of freshness can also be achieved with ice cubes.

The clearly visible filling level indicator shows you at a glance whether the large 10-litre tank still contains enough water. When the water tank is empty, the water pump switches off automatically while the fan keeps running for air freshening. This is indicated by the LED of the air cooling function flashing. Another big plus is the water tank that can be cleaned quickly and easily.

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

With the PAE 40 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 can be furthermore ideally used as an effective humidifier 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 40 you benefit from pleasant air cooling, refreshing ventilation, agreeable humidification and doubly cleaned room air. 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 40

Using air coolers as humidifiers during the wintertime

Air coolers are most effective 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.
