Description
Kevlar gearing reduces wear,
more than doubling damper
life.
Adjustable range stops.
Mechanical visual position
indicator for damper status.
Solid construction using
extruded aluminum frame and
blades.
Parallel blade design for low
leakage performance.
Quieter operation with fewer
blades.
Simple, easy-to-wire,
two-wire installation.
Reliable, strong, 24-volt
spring-return motor.
Fail-safe, normally open
operation.
Compatible with conventional
and networked zoning.
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 a 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).
