Zonefirst SPRD-9 Damper Els PW 17895 check for 24V at theThe Zonefirst SPRD 9 is a professional grade 9 inch round barometric static pressure regulating damper engineered for precise HVAC bypass management in multi zone systems. This mechanical, non electrical component utilizes a weighted counter balance arm to automatically relieve excessive static pressure as individual zone dampers close. When the air pressure in the supply plenum exceeds your calibrated setpoint, the damper blade opens to bypass air
