        Zonefirst® SPRD09 Static Pressure Relief Damper, 9 in, 22 ga Steel, Galvaniz

        Zonefirst® SPRD09

        The static pressure regulating dampers, model SPRD, are barometric relief dampers used to by-pass excess air pressure on zoned systems. The SPRDs automatically respond to the air pressure in duct as the various zone dampers open and close.

        Zonefirst® Static Pressure Relief Damper, Series: SPRD, 9 in Size, 600 cu-ft/min, Single Blade, 22 ga Steel, Galvanized, Round, 0.5 in WC Differential Pressure Pressure, 0 - 180 deg F Operating, -20 to 190 deg F Storage

        • The SPRD helps maintain a constant air pressure in the duct system
        • This reduces noise that is caused by high air pressures and velocities, as well as maintains a constant volume of air (cu-ft/min) through the duct system
        • Maintaining a constant volume of air through the HVAC system keeps the efficiency of the system at its maximum
        • 5 - 95% non-condensing humidity
