Description
The OE524 Round Pressure Independent 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 OE744-31-VAVZ and OE744-32-VAVZ VAVZ
Pressure Independent Zone Controller Actuator
Packages which are field mounted on the OE524
Round Pressure Independent Zone Damper. The
Round Pressure Independent Zone Damper also
has a patented Tri Averaging Flow Sensor
® built
in to provide accurate airflow measurement when
connected to the flow sensor provided with the
Pressure Independent Zone Controller Actuator
Packages.
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 Independent Zone Dampers, select from the Zone
Damper Airflow Chart and follow the Zone Damper Guidelines on page 2 of this document.
Mounting
The Pressure Independent Round Zone Damper assembly should be mounted according to standard duct instal-
lation practices with airflow direction as shown in the illustration above. After installation of the Round Zone
Damper 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
Assembly 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.
