PAE 21 air cooler
Combined 3-in-1 solution: uniting air cooler, fan and humidifier in one device – ideal to be used all year
Glory in the soothing refreshment provided by a welcome breeze
When your home or office heats up during the summer and the air gets stuffy and stagnant, the elegant air cooler PAE 21 can provide a relief making use of the natural principle of evaporation. With its 5.6 l water tank and an evaporation performance of 0.8 litres per hour the PAE 21 can emit fresh breaths of air for up to 7 hours without needing a refill. Additionally, the device can offer three fan stages which means that it produces soothing refreshment even when used as a fan without cooling function. Activating the automatic swing function ensures an even air distribution: the internal vertical fins are constantly turning to and fro. The external horizontal fins on the other hand can be manually adjusted as desired to discharge the air current towards the front, top or bottom. The easily removable air filter filters dust, fluff and animal hair from the room air.
Natural cooling principle
The mobile air cooler PAE 21 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. The PAE 21 work just the same: Located within the air cooler is a honeycomb filter soaked with water. The warm air is directed from the rear of the device through the wet filter and in passing 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 of the PAE 21. This additional boost of freshness can also be achieved with ice cubes.
Enjoy pleasant refreshment! You can also find all the relevant information about our comfort air conditioning units in the product brochure. Download the PDF directly here.
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.
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.
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.
PAE 21 – the uncomplicated cooling solution
In contrast to air conditioners air coolers do not make use of any chemical cooling agents. As previously described, the cooling effect is generated in a natural manner. Moreover, neither an exhaust air hose is required nor any elaborate installations.
Simply set the device up and chill in refreshing coolness
Simply position the air cooler precisely where a little cooling is required. Once you have filled the water tank and connected the power cable, you can lean back, relax and just enjoy the fresh breeze. By means of the recessed handles and the smooth-running wheels fitted parking brakes the air cooler can easily be moved from one location to the next.
Can be operated all year round – air cooler in the summer, humidifier in the winter
Using the PAE 21 you can rejoice at the produced feel-good climate all 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. And after that it won't take long until the heating season starts. In autumn and winter, the PAE 21 is an effective humidifier creating an agreeable room climate and protecting your respiratory tract from the effects of excessively dry heated air. With an air flow rate of 276 m³ per hour and an evaporation performance of 0.8 litres per hour the device ensures an agreeable humidity level in the room.
The stylish design of the PAE 21 will, no doubt, splendidly fit into your living or office environment. And with 50 watts of power the operation is permanently economical and energy-efficient.
