Honeywell 12" Round Automatic Damper (PC/SO)

FEATURES

The ARD is a power close and spring open zone damper. It has a 24-volt motor used to control circulating air in HVAC systems and is used when normally open damper is required. The ARD is typically used with TrueZONE electronic zoning systems and others.

• Adjustable close position range stops.
• Shipped as power closed/spring return open damper.
• Available in 5 to 10 inch, 12, 14, 16, 18, and 20 inch diameter sizes.
• Male (crimped) and female (uncrimped) ends to connect to any rigid or flexible round duct.
• Rated to operate up to 1 in. wc.
• Blade closes off tightly against gasket for minimal leakage.
• Fail-safe, normally open operation.
• Simple, easy-to-wire, two-wire (M1 and M6) installation. Optional third wire (M4) powers LED in open position only (does not power motor).
