The benefits of using TEL’s auto sash controllers

People working with industrial and educational fume cupboards must be protected at all times. Auto sash controllers are designed specifically to keep users safe. TEL’s auto sash controller, not only keeps users safe, it offers many other benefits too:

Increased safety

Our automatic sash controllers use a passive infra-red sensor (PIR) to continually monitor the work area in front of a fume cupboard to increase the safety of operators. It automatically closes the sash when the fume cupboard operator is no longer present and reopens when they return. It also recognises when an obstacle is in the way and prevents the sash from closing on it.

Energy and cost savings

Our automatic sash closer will maximise and guarantee energy savings, reducing costs and carbon emissions. TEL’s auto sash controllers helped to ensure that Ohio State University achieved its Silver LEED Sustainability Rating and earned the Environmental Protection Agency’s Labs21 certification.

More control

When the operator is present our auto sash controllers give operators the capability to operate the sash manually via a footswitch or by using the Tiptronic touch-sensitive feature to drive the sash up or down.

More flexibility

Although primarily designed to use on VAV fume cupboards, our auto sash controller can also be used on CAV fume cupboards. We also offer dual auto sash controllers to use on fume cupboards with two sashes, including walk-in, back to back and side by side types.


TEL’s auto sash controller can be fitted to new or existing fume cupboards, with a choice of motor drive systems to suit any type of fume cupboard.

Complete integration

And, TEL has developed a fully integrated airflow controlling and auto sash system to automatically adjust the airflow according to need, decreasing the volume of air extracted when laboratory fume cupboards are not in use and minimising energy consumption.
