ZD Series
Zone Dampers
Description:
The ZD series are extruded aluminum parallel blade
dampers complete with a 24 Volt, spring return motor
actuator. These dampers are shipped complete and
ready for installation. The lightweight ZD can be
installed in any position in any properly sized duct. All
ZD dampers are rated for duct systems less than 1.0”
W.C.
All ZD dampers are typically shipped as Normally
Open dampers that are powered closed and spring
returned opened.
A 24 Volt AC, 50/60 Hz, spring return damper motor,
powers the ZD. The motor powers the damper closed
and spring returns the damper open for fail-safe
operation. Providing power to the damper drives the
damper closed. Removing power from the motor
allows the motor to spring back to the open position.
The 24 Volt, hysteresis, synchronous motor has been
tested to over 250,000 cycles to provide long life.
Even replacing the motor is a simple less than one
(1) minute change by loosening the setscrew holding
the motor onto the damper.
The ZD motor also has a simple adjustment for
setting the damper to a minimum position. A
minimum position allows for excess by-pass air. To
set a minimum position, loosen the setscrew, align
the setscrew to the minimum position label and
re-tighten.
