Worm gear operators of the pneumatic, electric or hand-operated with chain-wheel types are also offered. Long life Teflon bearings and custom-designed molded plastic bushings, located on the exterior of damper, require minimal maintenance and ensure continuous free movement of the blade. Stops, (stiffeners as required), are used to support and seat the FRP blade. All metal parts are at a minimum 316 stainless steel. Dampers range from sizes 4” diameter to 60” diameter.
