ZD Series Dampers

APPLICATION

The ZD is a power close, and spring open damper. It has a

24-volt, spring-return, power-closed damper motor used to

control circulating air in heating, cooling and ventilating

systems. It is used when a normally-open damper is required.

The ZD is typically used with the TotalZone® Systems and

other electronic mini-zone damper systems.

FEATURES

• Reliable spring-return motor.

• Fail-safe, normally-open operation.

• Strong 24-volt spring-return motor.

• Quiet operation with fewer blades.

• Simple, easy-to-wire, two-wire operation.

• Parallel blade design for low leakage performance.

• Easy slip-in design.

• Solid construction using extruded aluminum frame

and blades.

• Can be mounted on the side or bottom of the duct, as

the application requires.
