Brand: Zonex
Item No: STMPD18
Sign In for AvailabilityDescription
The STMPD is a medium pressure, power open/power close and pressure dependent modulating supply air damper. The 6 to 10 in Dia damper cylinders are fabricated from 22 ga steel and the 12 to 18 in Dia cylinders from 20 ga steel. Rolled beads are at the ends of every damper to provide maximum structural integrity. The trailing end is crimped for ease of installation into duct work. STMPD dampers feature an elliptical blade for linear air volume delivery throughout the damper range of travel. The damper blade is bolted to the hexagonal damper shaft. A positive air seal is accomplished through use of a high density foam gasket around the blade perimeter. STMPD dampers feature 24 VAC full stall motors that do not require the use of end switches to terminate travel. Each STMPD is powered and controlled by its respective zone thermostat. Dampers can be wired in parallel to provide additional zone CFM capacity when required.
