The Young Regulator Model 820-1200 rectangular opposed blade damper is constructed of aluminum and stainless steel for long, corrosion-resistant operation It is ideal for balancing dampers where opposed blade design is desired for better control, less noise and turbulence than single blade dampers. Individual Teflon blade bushings provide smooth, quiet operation for the life of the damper. There is a mounting plate for slip-in installation. This is a high free area damper for lower pressure drop across the damper.
The Young 1200 self-locking right angle worm gear regulator installed at the factory, is used when an operating shaft must be carried down at a right angle to the damper shaft. It may be used together with a variety of Young regulators, including 301, 315, 896C and flex shaft to operate dampers from the ceiling line. The 1200 is made of heavy-duty steel and die cast construction.
