ZoneFirst MSS Damper Actuator Els PW 17895 allowing for control over bothThe ZoneFirst MSS Damper Actuator is a 24VAC spring return damper motor engineered for direct replacement of legacy MSR damper motor, MCS 3, MCSR, RDM, and RDMH models. Specifically designed for professional grade HVAC zoning systems, this 2 wire actuator provides silent operation with a patented air brake system that prevents the slamming and gear noise common in standard spring return units. The direct drive actuator powers the damper to the closed
