Design air cooler PAE 45

Turbo cooling, invigorating wind, humidification and air purification in just one device

Double-power turbo spin cooling for hot summer days

The modern air cooler PAE 45 with infrared remote control counteracts hot summer temperatures with refreshing, icy air currents from two high-performance blowers with Turbospin technology and a range of 15 metres. Heated offices, living spaces or shops can be cooled down to pleasant room temperatures at turbo speed with this air cooler, which is not only visually outstanding. The PAE 45 cools its air current down by up to 2 – 3 °C and thus ensures an optimal temperature difference between outside and inside temperature so that the body is not unnecessarily stressed. In addition to natural evaporation cooling, the elegantly slim 4-in-1 air cooler (air cooling, air freshening, ventilation and humidification) humidifies and cleans the room air to offer refreshment with hygienically clean and optimally humidified cold air even at the highest of summer temperatures. The air flow rate of the dual fan can be adjusted in five stages. Invisible easy-running wheels make the pure white design device appear to float over the floor.

Natural, energy-saving cooling – without chemicals or hoses

With its innovative honeycomb cooling technology the air cooler PAE 45 provides invigorating freshness and cooling in an incomparably energy-efficient way. It cools the room air using the natural principle of water evaporation, which is also referred to as adiabatic cooling. Everyone knows this cooling effect, for example from sweat evaporation or cooler air in the vicinity of water falls, rivers and lakes. It becomes even more noticeable than with other air coolers due to the extremely strong wind current. As there is no energy-hungry compressor technology integrated in the PAE 45, its energy costs are far below those of a mobile air conditioner. Furthermore, the device does not require an unsightly exhaust hose either, let alone an external unit on the facade, through which the warm air is discharged to the outside in conventional air conditioners. The cooling giant withdraws heat from the room air via natural evaporation of its cold or ice water filling. The warm air flowing into the device on three sides is cooled by means of honeycomb filters, cleaned in the integrated air filter and blown out into the room as an icy fresh breeze via the two high-performance blowers with aerodynamically shaped air outlet louvres in the shape of a hurricane. With its impressive turbo spin air flow rate of 1,700 m³/h and a generous and easy-to-clean 10-litre water tank, the air cooler is recommended for use in rooms sized up to 136 m² or 340 m³. Moreover, the PAE 45 has an automatic drying function to protect the 3 honeycomb filters from mould growth when stored – simply press the speed button for 3 seconds. The device will then run at the highest fan stage and switch off automatically after 20 minutes, when the filters have been dried completely.

Cool boost of freshness with additional health protection

Thanks to the outstanding triple combination of air cooling, humidification and ventilation, you can benefit from a room climate improved multiple times when using the PAE 45 – and additionally 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 keeps the nasal mucous membranes, which are important for the immune defence, moist. As a humidifier for year-round use, the PAE 45 impresses with a humidification performance of 1.2 l/h to keep the room humidity level in the optimum range of 40–60 %. In addition, the PAE 45 can also be used as a fully-fledged dual fan with two refreshing 360° air currents throughout the year with the air cooling and humidification function deactivated. To either direct the cooling air to a specific point or distribute it in the entire room, the device has an on-demand 80° swing mode for extensive distribution of the cold air.

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.

Turbo-powered features and performance

No matter whether you use the PAE 45 for rapid cooling on hot summer days or to humidify heated air that is too dry to improve the indoor climate in winter – the air cooler PAE 45 demonstrates the benefits of its turbo spin technology in all operating modes and impresses with outstanding features.

Flow-optimized turbo spin cold air distribution

You're familiar with the problem for sure: in rooms and flat with nooks and crannies and high ceilings, the refreshing cold air does not always reach all areas of the room. As soon as you get up from your desk or sofa and cross the room, you change from a cool temperature zone to a warm one. The reason for this is an insufficient distribution of the cold air in the room.

The PAE 45 cools with no limits!

The turbo spin technology of the air cooler generates an even circulation of the cold air in the entire room. The warm air flowing into the device from three sides is cooled and then directed onto the aerodynamically shaped rotor blades of the extremely fast rotating impellers of the high-performance fans. Thanks to Turbospin technology, the curved fan blades produce a particularly powerful swirl and accelerate the air current enormously. With its air flow rate of 1,700 m, the PAE 45 is up to 3 times more powerful than comparable air coolers. The extremely compressed turbulent air currents gush out of the device as two tornado-like cold air columns that revolve around themselves and advance up to 15 metres into the room. Once the exiting air currents hit a wall or ceiling, they are deflected to all sides. In a constant circulation the air returns to the rear of the air cooler along the walls and the ceiling. It is sucked in once more to start a new cycle. This effective turbo spin method ensures maximum circulation and mixing of the room air. The cooling effect of the air currents can be felt in the entire room!

For comparison: A conventional air cooler with a comparable air flow rate blows out the cold air across a distance of approx. 6 metres. With an increasing distance, the cooling effect of the air current decreases. Owing to the turbo spin technology of the PAE 45 the air ejection distance is increased to up to 15 metres. The strongly accelerated cold air is deflected by the walls and distributed to all nooks and crannies of the room.

Ultra-silent night mode for a restful sleep and soothing air freshening function

The air cooler PAE 45 puts an end to sleepless nights caused by heat in the bedroom. An ultra-silent night mode with gradual reduction of the fan speed lulls you into a restful sleep with a pleasantly cool breeze. After a preset time, the selected fan stage changes to a ventilation performance optimized for sleep requirements with the lowest intensity. The PAE 45 is also recommended as a humidifier in heated bedrooms. Heated air that is too dry can have just as negative an effect on sleep as temperatures that are too cold or too warm. With the humidification function of the PAE 45, the humidity level is constantly kept in a healthy feel-good range even when the heating is on.
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.

Programmable timer for energy-saving auto switch-off

The PAE 45 keeps an eye on your electricity costs. The air cooler refreshes and cools only as long as you wish or set it. With the convenient timer function, you can programme an individually preset time after which the device switches off fully automatically. The operating time until auto switch-off can be preselected from 1 to 9 hours in increments of 1 hour. The timer function is recommended when the device is used in the bedroom, so the air cooler will switch off fully automatically in an energy-saving way after you have fallen asleep with a cool air flow.

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

With the PAE 45 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 5 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.

The 4-in-1 air cooler PAE 45 provides soothing refreshment in the summer and a room climate that is improved by four times 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 45

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.
