Zonex Systems
zone dampers are used in
cooling/heating systems to provide room by
room zone control. The damper is provided
zone damper is controlled by a zone thermostat.
More than one damper can be controlled by
one zone thermostat. Use this table to determine
which zone dampers to use.
ROUND MEDIUM PRESSURE ZONE DAMPERS
Zonex Systems
round medium pressure zone dampers are recommended for systems
with a maximum differential static pressure up to 1.75”. This modulating power
open/power close damper is manufactured from 20-22 gauge galvanized steel with
rolled-in stiffening beads for superior rigidity. Mechanical minimum and maximum
set stops are provided and easily adjustable. The damper is elliptical, which allows the
airflow to be tracked linearly. The damper pipe is furnished with one crimped end and
one straight end for easy installation. Do not install damper in an inverted position.

ZONE DAMPERS
Maximum Differential Pressure refers to the maximum static pressure drop in inches of water column between
the input (upstream) of the zone damper and the output (downstream) when the damper is closed.

A hat section supports a reversing, 24vac, 60Hz, 2 VA motor. A magnetic clutch
allows for continuous power to the motor and longer motor life. Motor drive time from
full open to full close is 90 seconds.
