Honywell SPRD12, sprd-12 pressure regulating damper 12"
12 in. Round Static Pressure Regulating Damper
Single-blade, steel barometric damper used to bypass excess air when majority of zone dampers are closed.
Counter-balanced weighted arm to control bypass air for zoned systems.
Available in rectangular/square and round sizes.
Air pressure in duct system increases as zone dampers close, pushing the SPRD open automatically.
Arm and weight both adjustable to control amount of air bypassed.

For larger systems and tighter pressure control, use MARD damper and static pressure controller (SPC).
