Abstract (en)
A powered air supply unit for a respirator for connection by a flexible hose to a facepiece or headpiece for supplying air thereto, comprises a generally rectangular housing (1) comprising side walls (2) closed at one end by an end wall (5) and at the other end defining an opening (3) with a stepped periphery in which one or more units (25, 27) of filter materials are located. A removable protective cover (4) retains the filter unit or units in opening (3) and is apertured to permit air to flow to opening (3). Within the housing, a centrifugal pump (13) with a d.c. motor (14) connected directly to the shaft (18) of the pump are provided side-by-side with a battery housing (15) for batteries to drive the motor. The inlet (21) of the pump (13) opens within the housing and the outlet (20) of the pump is connected directly to an outlet (6) in one side wall of the housing (1) and which is intended for connection to the flexible hose.
