Auto Sash Controllers

TEL’s innovative auto sash controller for fume hoods maximizes energy savings and provides increased safety for the operator.

The auto sash controller is designed to close the sash automatically when the operator is not present in front of the fume hood. A passive infrared sensor (PIR) constantly monitors the work area in front of the fume hood. When the operator is present the sash can be operated manually via the optional Tiptronic touch sensitive feature or using an optional foot switch. If no movement is detected and the sash opening is clear, the sash will automatically close after a pre-determined time. Auto open option is also available.
