When summer turns up its heat once again, the 4-in-1 air cooler PAE 31 (air cooling, air freshening, ventilation and humidification) provides an icy fresh air flow for quick cooling. The PAE 31 cools its air current down to 2 – 3 °C and thus ensures an optimal temperature difference between outside and inside temperature so that the body is not unnecessarily stressed. The high-performance blower with turbo spin technology and a range of 10 metres cools down hot living and business rooms, conservatories, offices and shops to pleasant room temperatures at an impressively quick speed. At the same time, the all-rounder cleans and humidifies the room air to refresh you with clean and optimally humidified cold air. The ventilation performance of the turbo spin fan is adjustable in three stages.

Natural cooling by evaporation with economic efficiency

The innovative honeycomb cooling technology of the air cooler PAE 31 is something you know from nature. Once a breeze blows over damp skin, you immediately feel a pleasant cooling sensation on your skin. The cooling effect is caused by the evaporation of the water. The thermal energy required for this process is withdrawn from the warm air, and the temperature drops noticeably. The PAE 31 also makes use of this natural cooling effect with its cold water or ice water filling. Once the warm room air flows through the humid honeycomb filters, the air is cooled down as thermal energy is withdrawn. Then, the air is humidified with cold or ice-cold water to be cleaned in the air filter afterwards and to be finally blown out into the room as an icy fresh breeze in the shape of a hurricane via the turbo spin high-performance fan. No chemicals, no energy-consuming cooling compressors and no disturbing exhaust air hoses are used in this process.

The hotter the day, the stronger the cooling capacity

Where conventional air conditioners reach their performance limits, the PAE 31 turns up its cooling capacity. The warmer the room air, the faster the humidity evaporates inside the honeycomb filter and the more heat is withdrawn from the air due to the evaporation process. So you can always rely on the cooling capacity of the PAE 31 to keep up with outside temperatures. With its powerful turbo spin air flow rate of 1,000 m³/h and a generous and easy-to-clean 6-litre water tank, the air cooler is recommended for use in rooms sized up to 26 m² or 65 m³.

Threefold improvement in indoor air quality with additional health protection

The combined air cooling, air humidification and air purification modes of the PAE 31 noticeably improve the room climate and repels pathogens from the air at the same time. 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 viral infection and keeps the nasal mucous membranes, which are important for the immune defence, moist. As a humidifier for year-round use, the PAE 31 impresses with a humidification performance of 1.1 l/h to keep the humidity level in the optimum range of 40–60 %. In addition, the PAE 31 can be used as a refreshing fan throughout the year even without the air cooling and humidification function. To either direct the cooling air flow to a specific point or to distribute it in the entire room, the device has an on-demand all-round swing mode and air outlet fins that rotate automatically by 360° to provide for large-scale cold air distribution.

If the summer heat keeps you awake, the PAE 31 provides relief with its ultra-silent night mode. A preset programme of different fan stages lets you drift off to sleep while providing for optimal cooling. The ventilation performance is reduced every 30 minutes until the air cooler permanently cools and refreshes with minimal noise at the lowest fan stage.
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 timer function of the PAE 31 allows for time-controlled cooling with individually preset switch-off time. The operating time until auto switch-off can be set to 1 h, 2 h, 4 h or 8 h. The timer function is recommended, for example, when the device is used in the office. After an 8-hour working day, the device switches off fully automatically so you do not even have to think about it.

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

With the PAE 31 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 3 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 PAE 31 4-in-1 air cooler provides the necessary level of natural cooling and freshness at any temperature.
