Air Filters housings have been developed for the purification of compressed air and other technical gases in industrial ranges of application. Due to the optimized construction, they offer low differential pressure at high flow rates. Numerous different sizes of housings with various connections make it possible to adopt the filter system to exactly the needed requirements. The Donaldson plug connection guarantees that the elements remain safely fixed at all times. Due to the modular design different element types can be installed into the housing, resulting in a highly flexible filtration system.
