How does the Auto Sash Controller work?                                                                           

A passive infra-red sensor (PIR) continually monitors the work area in front of the fume cupboard. 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 predetermined time, an auto open option is also available.

What products can the Auto Sash Controller can be used in conjunction with?

Auto sash controllers can be used on VAV and CAV fume hoods for increased laboratory safety.  They can be fitted to new or existing fume hoods with a choice of three motor drive systems.  A dual auto sash controller is also available to operate on fume cupboards with two sashes including walk in, back to back and side by side sashes.
