SPRD-20X20
The Static Pressure Regulating Dampers, Model SPRD, are barometric relief dampers used to by-pass excess air pressure on zoned systems. The SPRDs automatically respond to the air pressure in duct as the various zone dampers open and close.

As zone dampers close off air to a number of zones, the supply air pressure in the duct system will increase. This increase in air pressure can increase the noise level and reduce the flow of conditioned air through the HVAC Unit. Using the SPRD solves this by automatically compensating for the excess air pressure by opening on the increased pressure and relieving the excess air. The SPRD helps maintain a constant air pressure in the duct system. This reduces noise that is caused by high air pressures and velocities, as well as maintains a constant volume of air (CFM) through the duct system. Maintaining a constant volume of air through the HVAC System keeps the efficiency of the system at its maximum.
