Description
The OE524-XX-PD Round Pressure Dependent
Zone Damper consists of a Round Air Damper with
a control mounting plate on the side of the damper
housing. This plate is designed for mounting of the
OE742-31-VAVZ and OE742-32-VAVZ VAVZ
Pressure Dependent Zone Controller Actuator
Packages which are field mounted on the OE524-
XX-PD Round Pressure Dependent Zone Damper.
The Round Air Damper is constructed of 20 gauge
galvanized steel with a 14 gauge galvanized steel
blade. The damper has a full circumference EPDM
rubber gasket seal providing a Class 2 leakage
rating. The ½” damper shaft rotates in a stainless
steel bushing. A slot is cut into the end of the
damper shaft for damper position indication.
All Round Dampers are tested for performance in
accordance with AMCA 500-D standards.
When selecting Round Dampers for use as a
Pressure Dependent Zone Dampers, select from
the Zone Damper Airflow Chart and follow the
Zone Damper Guidelines on page 2 of this docu-
ment.
Mounting
The Pressure Dependent Round Zone Damper assembly should be mounted according to standard duct installa-
tion practices with airflow direction as shown in the illustration above. After installation of the Round Zone Damp-
er in the ductwork, insulation should be applied around any remaining uninsulated surface on the air valve inlet
and outlet. The Round Zone Damper should be mounted so the control enclosure is positioned to the left or right
side of the ductwork with the control enclosure in a vertical plane. Do not mount the Round Zone Damper As-
sembly with the control enclosure on the top or bottom of the ductwork. Adequate clearance should be main-
tained between the control panel and any obstruction to allow for removal of the control panel cover and access
to the controls.
