  • More details

For very heavy duty and continuous service. This 3 phase vacuum can be connected to CVS used in various sectors as agricultural-food production or metal-working industries.

 Many optionals are available for heavy material and/or in large quantities. The electric filter shaker is standard supply.

The 3997 has a 22 Kw, three phase, aluminium casting induction motor directly driven to the fan. The self cooling suction unit can work continuously, without the need of any maintenance.

The suction unit is run by an electric box with a stardelta-star starting, housed in the rear casing and power is supplied by a 9 meters-long, 4 core cable. The on/off switches are within a control panel, in the upper part of the rear casing.

In the control panel, there are also a timer and a manometer to enable visual control of the filter condition. An external electric filter shaker enables easy and efficient filter cleaning. The "L" class star filter is mounted on the vac as standard and guaranties an efficient filtration. The cyclone plate is already incorporated into the filter chamber in order to protect the filter itself.

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

The machine body is made of heavy duty tubular steel and painted with epoxy powders, to ensure robustness and a longer lifetime. An useful basket tool is mounted on the rear casing. The head of the filter housing is easily detachable by means of 4 hooks.

In the low part there are two guides to help moving the machine through a forklift.

The stability of the machine is ensured by the position of the suction unit placed at the bottom of the casing.
