ZoneFirst SPRD-12X8 Damper Els PW 17895 This is a mechanical vaporThe ZoneFirst SPRD 12X8 is a professional grade barometric static pressure regulating damper designed to maintain optimal bypass airflow in multi zone HVAC systems. As the direct replacement for the PRD 12X8, this 12" wide by 8" high rectangular unit utilizes a counter balanced weighted arm to automatically bleed off excess static pressure when zone dampers close. This critical function prevents high velocity air noise, protects the heat exchanger
