An air pump assembly (10) is provided which has a through flow type air-driving device (12) supported on an apertured partition wall (18) with the air-driving device (12) at one side and the motor (50) at the opposite side. The wall (18) is sandwiched between opposed pump and motor housings (14and 16) providing complementary ducts (27and 28) which communicate with opposed end caps (25 and 26) mounted on the end walls (21 and 22) of the pump and motor housings (14 and 16). The pump housing end wall (21) is apertured for air flow into the air-driving device (12) from the end cap (25) and its side wall supports an air outlet connection (13). A circuitous inlet passage to the air-driving device (12) is formed through end cap (26), ducts (27 and 28) and end cap (25). A circuitous outlet passage is formed from the air-driving device (12) through the motor housing (16), apertured partition wall (18) and motor housing (16).
