Zonefirst ZDS-36X8 36WX8H Parallel 24V 2-Pos S/R Refrigerant preventing the structural deformation thatThe Zonefirst ZDS 36X8 is a high performance side mount zone damper engineered for horizontal or vertical trunk lines. Measuring 36 inches wide by 8 inches high, this 24V HVAC damper utilizes a 2 wire spring return motorized actuator (MSS motor), ensuring a fail safe position when power is interrupted. Built from heavy duty extruded aluminum with mitre angles and a zinc plated linkage arm, the ZDS 36X8 is rated for static pressures up to 1. 0 W. C.
