Product Overview

Pressing the Emergency Purge button a second time reverts the Fume Hood Controller to normal operation for the current conditions.

HI/LO: HI/OFF Select button – Pressing this button changes the controller from a high flow setpoint to a low flow setpoint and back again or changes the controller from a high flow setpoint to and OFF state and back again.

Auxiliary Button – The Auxiliary buttons are not used currently.

For more information on the ODP, see the Fume Hood Controller Operator Display Panel User's Card (125-1976).

Laboratory Exhaust Air Terminal

The Laboratory Exhaust Air Terminal is a pre-packaged, easy to install, airflow measurement and control station. See Figure 5. It combines an orifice plate flow sensor, differential pressure transmitter, an electronic actuator assembly, or No. 3 pneumatic actuator, and Analog Output-Pneumatic (AO-P) Module, and butterfly damper in a 20 gauge 316 stainless steel duct section.

This arrangement provides fast acting, stable, and precise VAV fume hood exhaust airflow control.
