ZoneFirst SPRD-14 Damper R-410A and steady 24V communication signalsThe ZoneFirst SPRD 14 Damper is a 14 inch round barometric static pressure regulating damper designed for high performance HVAC zoning. In a multi zone system, as individual zone dampers close, duct static pressure naturally increases. This barometric relief damper utilizes a single blade, counter balanced weighted arm to automatically compensate for this excess pressure, preventing coil freeze ups and high limit trips. Specifically engineered for
