Zonex DigiTract 4 - RECTANGULAR BYPASS SELECTION TABLE; SLAVING BYPASS DAMPERS

20
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.
SLAVING BYPASS DAMPERS
Use only one Pressure Sensor when slaving two or more Bypass Dampers together. Connect the Pressure Sensor to one damper. 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.
