Fume Hood Accessories Fume Hood Monitor with Integrated Auto Sash
Our innovative fume hood monitor with integrated auto sash can be factory installed on any of our vertical rising sash bench style fume hoods to help interface with building control systems to maximize energy savings and provide increased operator safety. This monitor works the same as the fume hood monitor and is designed to close the sash of vertically rising sash fume hoods automatically when the operator is not present in front of the fume hood. Using the fume hood monitor with auto sash integration means you will no longer need a separate auto sash keypad. A passive infrared sensor (PIR) constantly monitors the work area in front of the fume hood. If a person is not detected and the sash opening is clear, the sash will automatically close after a pre-determined time. An under-sash infrared sensor will stop sash movement upon detection of any object during auto sash movement. When an operator is present, the sash can be operated manually via the touch control pad or by the Tiptronic fea- ture. Auto Sash is available only with made-to-order chemical fume hoods with vertical rising sash. Contact your Fisher Scientific™ Sales Representative for assistance. Energy and Cost Savings Use of an automatic sash closer combined with a VAV HVAC system; will maximize and guar- antee energy savings, reducing operating costs and carbon emissions.
