Honeywell SPRD Static Pressure Regulating Damper, 12", Round, Import

• 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
• 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
• Recommended for low pressure systems with less than 0.5" WC
• For larger systems and tighter pressure control, use Mard damper and static pressure controller (SPC)
• Additional weights availableSid Harvey Item #:SPRD12: Replaces Part #:'s : L86-324,
