The air cooler provides exactly with 4-in-1 efficiency as a fan, air cooler, air purifier and humidifier with the best air. Cool freshness that pays off. With a powerful air flow rate of 384 m³/h, the fan sets sluggish summer air in motion and creates a pleasant breeze at four speeds. In combination with the air cooler function, the air flow is also pleasantly cooled and provides pinpoint refreshment. At the same time, the enriches the room air with up to 1100 ml per hour of pleasant humidity and is thus also a practical helper in winter by providing dry air with restful moisture. To do this, water is evaporated from the 10-litre tank via a honeycomb filter. This evaporation extracts heat from the air flowing through it in a natural and extremely energy-saving way - the air flow becomes a pleasantly cool breeze and refreshes with pinpoint accuracy, whether at the desk, on the couch or in bed. Two replaceable cooling accumulators for the water tank additionally lower the temperature for even more refreshment if desired. The water tank can be completely removed for easy filling, cleaning and emptying. If more than one person is to be refreshed, vertical and horizontal oscillation can be activated separately to let the air flow move. As a last function, an ionizer can also be activated. This enriches the air with ions that cause dirt particles to sink, thus purifying the air of dust and odours. Thanks to integrated castors, the 4-in-1 room freshener can be taken anywhere and is ready for use immediately. Finish: Black
