damper sleeve dimensional data
The drawings below and corresponding table show the position of the FSD-331 damper when mounted in a factory sleeve.
The standard mounting locations provide enough space for the mounting of actuators, controls and allow space for
installation of retaining angles and duct connections.
The standard location of a damper mounted in a factory sleeve ("A" dimension) is shown below. The damper can be
positioned at other locations within a range of 6 in. (152mm) to 12 in. (305mm) for the "A" dimension.
Actuators and Accessories
space envelopes
Externally mounted actuators always require space
outside of the damper sleeve. The “S” dimension
illustrates the clearance required for various available
actuators.
On dampers less than 18 in. (457mm) high, actuators
may also require clearances above and/or below
the sleeve. “B” and “T” dimensions are worst case
clearance requirements for some dampers less
than 18 in. (457 mm) high. All damper sizes under
18 in. (457mm) high do not require these worst case
clearances. If space availability above or below the
damper sleeve is limited, each damper size should be
individually evaluated.
