FEATURES
The TrueZONE® Bypass constant pressure regulating damper (CPRD) is a round static pressure relief damper. It is used in forced-air bypass applications to relieve excess static pressure when some of the zone dampers are closed. The damper is installed in a duct that delivers air to the return or a dump zone. The damper automatically opens and closes to maintain a desired static pressure.
The CPRD uses a calibrated spring to regulate the bypass air accurately when any number or combination of zones is calling. Conventional, weighted arm, bypass dampers may operate properly when one zone is calling; however, when different combinations of zones are calling, they bypass too much or too little. This can cause callbacks when homeowners complain of air noise.
• For bypass applications up to 1,000 CFM• No weights to balance
• Easy flex-duct installation
• Simple dial for setting when the system starts to bypass
• Can be installed at any orientation or angle
• Allows more airflow than typical weighted models, so you can install a smaller size
• Provides constant system pressure, regardless of zone changes or blower speed
• Calibrated spring tension regulator
