A ventilation fan (10, 200) includes a shaft assembly (22, 212), a rotor (24, 214), a motor housing (26, 216), and a bearing housing (28, 218). The shaft assembly (22, 212) defines a first port (90, 290) and a second port (92, 300). The rotor (24, 214) has a rotor first portion disposed about a first portion of the shaft assembly (22, 212) and a rotor second portion (122, 312) that extends from the rotor first portion (120, 310). The rotor first portion (120, 310) defines a rotor port (124, 314). The motor housing (26, 216) is disposed about a second portion of the shaft assembly. The motor housing (26, 216) defines a housing port. The bearing housing (28, 218) is operatively connected to the motor housing (26, 216).
