STAR Fume Hood Controller
Introducing PLASTEC’s brand new STAR Fume Hood controllers are designed for accurate monitoring and control over a fume hood. All of PLASTEC’s new controllers come equipped with an HD digital touchscreen interface and air speed sensor. The STAR Fume Hood Controller is available in multiple options, including Constant Air Volume (CAV), Variable Air Volume with PID Output (VAV PID), and Variable Air Volume with two speed settings (VAV 2-Speed). The CAV controller will monitor and display the airflow, as well as allow for On/Off control of the fan. It will also notify the user when the sash is too high when using a sash contact switch or if the airflow is insufficient. Both VAV controllers have similar control and monitoring as the CAV but with the additional of a 0–10V output for adjusting the fan speed and therefore the airflow as the sash opens or lowers. The PID controller will adjust the flow linearly with the sash. As the sash lowers, the speed sensor will read a lower air speed and
