RECTANGULAR BYPASS SELECTION TABLE

Bypass air in CFM.  Calculated at 1500 FPM.

Formula used:  B = W x H / 144 x 1500, where B = Bypass air in CFM, W = damper width in inches, H = damper height in inches, 

144 = 144 sq. inches per sq. ft., 1500 = 1500 FPM.

ROUND AND RECTANGULAR

BYPASS DAMPER MOTORS

SLAVING BYPASS DAMPERS

Use only one Pressure Sensor when slaving two or more 

Bypass Dampers together.  Connect the Pressure Sensor 

to  one  damper  as  described  above.  Connect  the  slave

dampers  in  parallel  as  shown.  Up  to  4  dampers  can  be 

slaved  to  one  Sensor.  The  slaved  dampers  will  self-

synchronize each time the dampers reach full open or full 

close.

To Static Pressure Control, as shown on the Bypass 

Wiring Diagram on the next page.
