Title: VENTILATION DEVICE FOR CLEAN ROOM APPLICATIONS
Abstract:
A ventilation device, particularly for supplying air to and extracting air from clean rooms, has a housing (2), in the interior (12) of which the following are arranged: a passage duct (16) that extends from a waste air inlet (13) provided on the housing (2) through the interior (12) to a supply air outlet (14) provided on the housing (2); a fan (49) arranged in the passage duct (16) in order to convey air from a suction-side chamber (47) fluidically connected to the waste air inlet (13) to a pressure-side chamber (48) fluidically connected to the supply air outlet (14), the speed of the fan (49) being controllable; an outside air duct (22) fluidically connected to an outside air connection (19) that is provided on the housing (2) and has an outside air outlet (23) in order to emit outside air into the passage duct (16), a first volume flow regulator (36) being installed in the outside air duct (22); an exhaust air duct (28) having an exhaust air inlet (29) fluidically connected to the passage duct (16) in order to receive a part of the waste air discharged (32) from the room as exhaust air (33) and an exhaust air connection (21) provided on the housing (2) in order to convey the received exhaust air out of the housing (2) to the outside, a second volume flow regulator (37) being installed in the exhaust air duct (28); and a control unit (68) for controlling the operation of the first and second volume flow regulators (36, 37) and the speed of the fan (49).
