For basic constant velocity fume hood control using sash position sensing, Tek-Air recommends model FVC-2600. This system utilizes sash position to reset the volume setpoint in the duct exhaust volume sensing equipment. Tek-Air’s VorTek airflow traverse probes provide volumetric measurement in that application.
The result of the exhaust volume changing based on sash position, allows the controller to maintain a constant face veloicty at the opening of the sash. The basic system consists of a controller, sash sensor(s), display unit, i/p transducer, and an exhaust air control valve with integral flow measurement sensors. The controller is typically wall-mounted above the fume hood.
The FVC2600 also works well with the AV3000 and BVP4000 Control valves when the I/P output is wired to the fast acting electric actuator.
