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.
