Honeywell ARD18TZU ARD Automatic Round Damper 24 Vac Spring-returnDamper Motor TrueZONE Round Supply Damper
18 in. Round Automatic Damper
The ARD is a round damper with a 24 Vac, spring-return damper motor used to control circulating air in heating, cooling, and ventilating systems.
The damper is shipped as a powered closed/spring return open damper. The damper can be field-converted to a power open/spring return closed damper when used as an independent zone or for fresh air intake for ventilation or combustion make-up air.
Honeywell Automatic Round Damper power-close, spring-open models ensure low leakage while controlling circulating air in heating, cooling and ventilation systems.
