Industrial Vacuum Cleaners - 39073907

CONTINUOUS AND RELIABLE VACUUM SYSTEMS

Optimum quality/price ratio for this three phase vacuum which offers high performance while still being extremely manoeuvrable and versatile.
It is designed for heavy duty use and constant service.

The suction unit is run by an electric board with star-delta-star starting, housed in the rear casing. The power is supplied by a 9 m.long, 4 core cable.

The control panel houses the on/off switch where there is also a timer and a manometer to enable a visual control of the filter condition. An external manual filter shaker enables an easy, hygienic and efficient filter cleaning.

The exclusive star-shaped, polyester filter allows a very effective filtration. If absolute filtration is required, a HEPA filter is available.

The steel waste bin with a capacity of 175 litre is fitted with castors and easily removable thanks to an exclusive, highly practical handle release system.

The body of the machine is made of heavy duty tubular steel and painted with epoxy powder, to ensure robustness and a longer lifetime.
The stability of the machine is ensured by the position of the suction unit, placed at the bottom of the rear casing.

Its manoeuvrability and ease of use is made possible by the 2 fixed wheels and 2 swivel ones, all with a diameter of 200 mm. and assembled with bearings.
