Damper or Venturi Air Valve to maintain control of a
chemical fume hood with up to 2 sashes. It uses
fast-acting electronic actuators (shipped separately)
to control the exhaust control device.
Item No. 570-136. Rev. CA
Installation Instructions
The application cannot detect a
broken wire to the analog input
for the second sash.
An external sash aggregating
device should be used to
calculate the face area for all
fume hoods with more than one
sash.
This controller supports up to two Offboard AVS
signals. Offboard Air Module(s) (OAM) house AVS
transducers and send signals to the AVS input(s) on
the controller board. The controller can operate
stand-alone, with a field panel, or as part of a
