LUEFTERVORRICHTUNG.

摘要

The ventilation device has its suction intake at the front in a horizontal plane and its air dispersion at the top in a vertical plane. The front surface of the ventilation device incorporates a number of evenly spaced axial fans (8,11), each associated with a common air filter (14) in an angled plane between the suction intake and the base of the housing of the ventilation device. The bottom row of axial fans (11) lie immediately behind the air filter (14), which extends over at least half the height of the housing, this height being at least twice the axial height of the fans (8,11). Pref. the air filter (14) fits between reception guides to allow its easy removal for cleaning or replacement.
