Fume Hood Controller: 2-Position Constant Volume

Application 940 is designed for use with a constant volume or two-position fume hood in a

manifold fume hood exhaust system. In this application, two position fume hoods have an

individual exhaust damper or venturi air valve connected to a central fan. The application

modulates the exhaust flow control device to maintain a high or low flow setpoint based on

inputs from the ODP (Operators Display Panel), Digital Input, an exhaust airflow sensor, and

the controller setpoints (Figure 10).
