- Recommended for low pressure systems with less than 0.5 inch WC
- For larger systems and tighter pressure control, use MARD damper and static pressure controller (SPC)
- Counter-balanced weighted arm to control bypass air for zoned systems
- Arm and weight both adjustable to control amount of air bypassed
- Air pressure in duct system increases as zone dampers close, pushing the SPRD open automatically
- Additional weights available
