10 OE50-XX-PT Round P.D. Zone Damper Assembly W/ Terminal Block Connectors Damper Sizing Use a load program to determine the peak load for each zone. These calculations will be used to select Zone Damper sizes. The Orion Systems utilize a typical low pressure duct design. To reduce airflow noise problems, duct pressures generally should not exceed W.C. Primary trunk ducts that are used with Orion systems should not be undersized. This is especially true of pressure dependent systems. With larger trunk ducts, it is easier to assure relatively constant pressure to each Zone Damper. Runs should be as short as possible, and the trunk duct system kept as symmetrical as possible to facilitate system balancing. Wherever possible, run the trunk ducts above corridors and locate the Zone Dampers in the areas above corridors to reduce the noise in the space and to facilitate service of the valves. Trunk ducts should be sized for no more than 0. W.C. drop per 00 ft. of duct, and a maximum duct velocity of 000 FPM. Using the maximum acceptable velocity for a branch duct (typically FPM for minimal noise), find the smallest Zone Damper that will deliver the required CFM as determined by the load program. Locate the branch velocity used in the duct design program in the left hand column of the Zone Damper Selection Data table. Move across the table and find the Zone Damper, which will provide the acceptable CFM to meet the zone airflow requirements. Note: Compare the Zone Damper size selected against the duct size to determine if the next size up or down will provide acceptable performance without requiring a transition fitting. Up to a maximum of two Slaved Zone Dampers may be slaved together with the main Zone Damper for large zones. This design should be reserved only for situations when it is not practical to use a single Zone Damper. See the Pressure Independent Zone Damper submittal sheet submittal sheet for information regarding application and selection of Round Slaved Zone Dampers.

14 OE59 - Rectangular Damper Description The OE59 Rectangular Damper is used in applications where rectangular duct is specified or required because of space limitations or job requirements. The Rectangular Damper utilizes opposed blades of airfoil design for improved air flow control. The Rectangular Damper frame is made of.080 thick extruded aluminum. The blades are also made of extruded aluminum. Blade pins are 7/6 hexagon shaped aluminum fixed to a Celcon inner bearing rotating within a polycarbonate outer bearing inserted in the damper frame. The Damper linkage is mechanically assembled and located in the damper frame. The linkage components are constructed of aluminum, zinc and nickel plated steel. Blade gaskets are made of extruded EPDM material and are secured within an integral slot on the blade. Jamb seals are of extruded TPE material for low leakage through the damper when closed. The control shaft is / diameter hexagon shaped rod and can be extended 9 past the damper frame for connection to the damper actuator. The damper shaft is shipped retracted into the frame area and must be adjusted to the required length in the field. Opposed Blade Profile Flanged to Duct Installation Mounting Dimensional Data The Rectangular Damper should be mounted in the ductwork according to standard duct installation practices. The rectangular damper should be selected for the nominal inside duct size. All Rectangular Dampers are supplied with flanges all around damper frame, making the overall damper width and height larger than the nominal inside duct size thus providing for external flange mounting to ductwork. The damper shaft is shipped retracted into the damper frame. Loosen the two nuts on the U-bolt that secures the damper shaft to the damper blade and adjust to length. It is recommended that the shaft length be adjusted so approximately 4 of shaft extends beyond the inside of the damper frame. Retighten the two nuts on the U-bolt that secures the damper shaft to the blade. After installation of the Rectangular Damper to the ductwork, it is recommended that insulation be applied around any non-insulated surface on the ductwork where the Rectangular Damper was installed. Damper Sizing Use a load program to determine the peak load for each zone. These calculations will be used in selecting the appropriate Rectangular Damper sizes. The Orion Systems utilize a typical low pressure duct design. To reduce noise problems, duct pressures should not exceed W.C. Primary trunk ducts used with Orion systems should not be undersized. This is especially true of pressure dependent systems. With pressure independent systems this is not as critical. With larger trunk ducts, it is easier to assure relatively constant pressure to each Rectangular Damper. Runs should be as short as possible, and the trunk duct system kept as symmetrical as possible to facilitate system balancing. Wherever possible, run the trunk ducts above corridors and locate the Rectangular Dampers above corridors to reduce the noise in the space and facilitate service of the valves. Trunk ducts should be sized for no more than 0. W.C. drop per 00 ft. of duct, and a maximum duct velocity of 000 FPM. Form: ORION-OE59-RectDmpr-Sub-0B.doc Page of

15 OE59 - Rectangular Damper Using the maximum acceptable velocity for a branch duct (typically FPM for minimal noise), find the smallest damper that will deliver the required CFM as determined by the load program. Locate the required CFM on the Rectangular Damper Selection Data table below. This table is based on an airflow velocity of 000 FPM across the damper. This is the recommended velocity for quiet operation and normal pressure drop through the damper. When space considerations or design criteria dictate, dampers may be selected for other face velocities by using the multipliers listed in the notes associated with the table. Move across the table and find the damper selection, which will provide the required CFM and fit within the ceiling area where the damper will be located. Many size selections are possible for a given CFM. Pressure drop across the damper is shown in parenthesis below the CFM.
