CPRD12 - HONEYWELL 12" ROUND TRUEZONE BYPASS DAMPER
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.
Features
Simplify zoning with bypass design
Constant pressure relief no matter the blower speed
Simple to install in any orientation
Easy to set crack pressure, no more fiddling with weights
Quick release regulator for easier installs and replacements
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.
