Resideo CPRD8 Bypass Damper Constant Pressure Regulator 8" Round

The Resideo CPRD8 Bypass Damper is an 8" round constant pressure regulator for HVAC systems. This bypass damper is constructed with galvanized steel for durability and molded plastic to ensure that it controls airflow to keep pressure in the ductwork constant thus ensuring the system is performing optimally. It is widely used in zoning systems to return excess air from over-pressurized zones back to the return air duct to prevent equipment such as furnaces and air handlers from being damaged by high pressure. It assists in increasing the durability of HVAC parts, enhances energy use, and enhances indoor comfort by promoting equal distribution of air.
