A healthy room climate without side effects

The PAE 51 serves to cool, ventilate, refresh and humidify the air.

Unlike an air conditioning system the air cooler PAE 51 does not reduce the room temperature by means of refrigerants, instead it makes use of the natural principle of evaporation resulting in the desired cooling effect. For this cooling process the device needs fresh tap water that is filled into the 20 l water tank. The integrated evaporation filter with honeycomb structure humidifies the sucked-in air and then discharges it as cold air through the fan. This chilled air current provides cool refreshment that is immediately noticeable on your skin.

Our recommendation: The water for filling the evaporative air cooler should be as cold as possible. Use ice packs or ice cubes for an additional cooling effect.

Healthy breathing to increase your well-being! Owing to its integrated air filter the PAE 51 can be used as humidifier and air freshener all year round. Especially in the dry winter months this can help to reduce the risk of catching a cold which is often promoted by dried-out mucous membranes from the dry heated air.

A few practical benefits:

  • 4-in-1 air cooler: air cooling, ventilation, air freshening and humidification
  • Efficient latent heat of evaporation with honeycomb technology
  • Operation with ice packs or ice cubes possible to increase cooling capacity
  • Natural wind mode

SecoSan – always the best water quality for refreshingly humidified room air

Continuous fresh water supply to ensure a healthy air quality.
To keep the water storage tank automatically 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.

The sucked-in air is cleaned by the integrated air filter and then humidified and cooled by means of the evaporation filter.

Socket hygrostat BH30 with air cooler PAE 51

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 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. For air coolers to be able to create the ideal or most agreeable humidity level in the room air, best use our socket hygrostat BH30. It is simply inserted between air cooler and socket where it automatically regulates the humidity.
