Volumetric Controls

Our volumetric controller is designed to provide variable airflow volume control and ensure the safety of users working with industrial and educational fume cupboards and fume hoods.

The Volumetric controller utilizes a bell mouth type venturi restrictor to accurately measure the extract volume of the fume cupboard and provides VAV control based on either sash position, programmable fixed set points or 0-10VDC analogue input.
The controller can also operate using 3rd party orifice plates or other manufactured restrictor devices.
