Sprd-10 10 in round static pressure regulating damper
SPRD10, SPRD-10, SPRD 10, 10 inch Round Static Pressure Regulating Damper
The Static Pressure Regulating Damper (SPRD) is a round or rectangular single-blade barometric relief damper used to prevent an excessive increase in air velocity. It is a mechanical damper with no electrical connections. The blade has a counter-balance weighted arm that can be adjusted to open when necessary. It is recommended for use on zone damper systems up to.5 in. static pressure and up to 2000 cfm. Systems above 2000 cfm may require use of the SPC static pressure control and MARD 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.
• Recommended for low pressure systems with less than 0.5 in. wc.
• For larger systems and tighter pressure control, use modulating dampers and static pressure controller (SPC).
• Additional weights order number SPRD-W
• Additional weights can be ordered separately.
• Available in: Round sizes 7, 8, 9, 10, 12, 14 and 16 in. diameters.
• Rectangular sizes (width x height)12 x 8, 12 x 10, 12 x 12, 20 x 8, 20 x 10, 20 x 12 in.
