Can inline centrifugal fans be used for continuous high temperature exhaust applications?
Inline centrifugal fans (GFC models TCB or TCF) are not recommended for use in high temperature continuous exhaust applications. The reason is based solely on inline centrifugal fan design, which has the impeller at the inlet of the housing. As seen on the following diagram, the fan housing becomes pressurized and heated to the temperature of the incoming air. Leakage of heated air and heat transfer through the bearing cover and belt tube reduce the life of the bearings and motor. Our recommendation is not to exceed 200° F with inline centrifugal fans.
