The Honeywell TrueZONE Bypass constant pressure regulating damper (CPRD) is a round static pressure relief damper. 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.
Features:
• Quick installation and setup
• No weight to adjust
• Can be installed in any orientation
• Engineered to provide constant system pressure regardless of changes in zones celling or blower speed
