Shaft Seal
A shaft seal for an exhaust fan. The seal limits leakage from within an exhaust fan housing around an exhaust fan drive shaft that extends between a rotational power source exterior to the exhaust fan housing and a position within the exhaust fan housing. The seal comprises a plenum generally positi...

| description | A shaft seal for an exhaust fan. The seal limits leakage from within an exhaust fan housing around an exhaust fan drive shaft that extends between a rotational power source exterior to the exhaust fan housing and a position within the exhaust fan housing. The seal comprises a plenum generally positioned about the exhaust fan drive shaft at the point where the shaft extends into the fan housing; an auxiliary blower comprising a housing, an internal blade driven by an auxiliary blower drive shaft, and an auxiliary blower drive to rotate the drive shaft where the auxiliary blower drive is operatively associated with the rotational power source such that operation of the rotational power sources causes a rotation of the exhaust fan drive shaft and the auxiliary blower drive shaft; and a duct fluidly connecting the auxiliary blower housing to the plenum. |
