Damper Sleeve Dimensional Data

The drawings below and corresponding table show the position of the SMD-203 damper when mounted in a factory sleeve. The standard mounting locations provide enough space for the mounting of actuators, controls and allow space for installa- tion 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 posi- tioned at other locations within a range of 6 in. (152mm) to 12 in. (305mm) for the "A" dimension.

Externally mounted actuators always require space out-

 

side 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 require-

 

ments for some dampers less than 18 in. (457mm) 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.
