(November 2014) A Totally Enclosed, Fan-Cooled (TEFC) electric motor is a type of industrial electric motor with an enclosure that does not permit outside air to freely circulate through the interior of the motor. An external fan blows outside air over the frame of the motor to cool it.
Outlet Volume Control Dampers are commonly used in variable air volume systems. Blades are mounted perpendicular to fan shaft for even force loading on the blades and to reduce pressure losses. The Greenheck âTotal Centrifugal Fan Packageâ Dampers are just one component of the Greenheck centrifugal fan package.xternal Inlet Vane Dampers are mounted in the airstream or directly to the fan housing leaving linkages accessible for maintenance. Often used for variable air volume retroï¬t applications. Inlet Box Dampers are used when applications require inlet boxes.
