Control Panels
Most fume hoods are fitted with a mains-powered control panel. Typically, they perform one or more of the following functions:
- Warn of low air flow.
- Warn of too large an opening at the front of the unit. Known as a "high sash" alarm, this is caused by the sliding glass at the front of the unit being raised higher than is considered safe, due to the resulting air velocity drop.
- Provide a method of switching the exhaust fan on or off.
- Provide a method of turning the internal light on or off.
Specific extra functions can be added, for example, a switch to turn a waterwash system on or off.
