Air Washer

The air washer can be applied either in centralized air handling systems or, as a stand-alone unit, in a central station of builderswork. The housing stands clear of the ground on a base frame and consists of stainless steel panels. A pump draws the water directly from the tank. In case of water filtration or of chilled water operation, an additional reservoir is used.The Air Washer is also available, without the stainless steel housing, for installation within existing central stations.
