ACCESSORIES
Some accessories are only supplied if specified with purchase.
Filter Pressure Gauges
A filter pressure gauge is fitted as standard to the front of each AirBench. This indicates performance of the unit
as a whole, and filter condition. Certain models show a red zone on the filter gauge; when the gauge indicates
within this zone, filters may be blocked or require cleaning. Turn the AirBench off and inspect the filters.
Where no red zone is shown, a filter inspection pressure drop will be recorded on the Commissioning
Certificate. When pressure loss is greater than that shown on the Commissioning Certificate, follow the above
procedure.
A high pressure reading may also indicate a blocked surface. Inspect the surface for blockages and clean if
required. Do not operate AirBench continuously with more than 75% of the surface blocked.
Hours Run Meter
The meter is not resettable and operates at all times when the speed control or switch is powered.
Wheels
Standard industrial rubber wheeled swivel castors are used. The two front wheels are lockable. Lock by
pressing on the lever and trip by flicking (models and operation vary slightly). Do not attempt to move while
brakes are on.

operational; and reduces energy use by switching off the fan after 5 minutes of non-use.
