Description
Overview
The ZD is a power close and
spring open damper. It has a
24-volt motor used to control
circulating air in HVAC
systems and used when a
normally-open damper is
required. The ZD is typically
used with the TrueZONE and
other electronic zoning
systems.
Features
•Mechanical visual position
indicator for damper status.
•Solid construction using
extruded aluminum frame and
blades.
•Parallel blade design for
low leakage performance.
•Simple, easy-to-wire,
two-wire installation.
•Reliable, strong, 24-volt
spring-return motor.
•Fail-safe, normally open
operation.
•Ordering Instructions: Order
ZD (dimension 1) x (dimension
2). (Motor is always mounted
on dimension 2 side.) For
example, ZD10x8 is a 10 in. x
8 in. damper with the motor
on the 8 in. side; but a
ZD8x10 is an 8 in. x 10 in.
damper that has the motor on
the 10 in. side.
•Damper can be installed in
any orientation (mounting
side can be on either the
bottom or the side of the
duct).
