Automatic Sash Operator
The Automatic Sash Operator is a great solution that offers energy savings to the
laboratory and provides user safety. It is designed to be factory mounted on a Mott
chain drive vertical rising sash fume hood. When combined with Variable Air Volume
systems, large energy savings will result because the sash closes after the user
exits the work area thus reducing exhaust volume and therefore also reducing energy
consumption. The sash will automatically open to the pre-set working height when
the operator returns to the fume hood working area. This system is also equipped
with a safety light beam, which will sense an obstruction and cause the sash to
disengage immediately once the presences of an object is detected.
