Industrial and ATEX Zone coded vacuums in which the common metal tank collection system is replaced with a 20 meters long continuous ultra-strong plastic tube bag. The LONGOPAC® system allows vacuumed material to be collected directly into bags that are sealed avoiding any direct contact with operators. Bag size and weight are varied according to the dust collected.

Tankless vacuums are driven by single or three phase turbines or compressed air. They have AUTOMATIC or SEMI-AUTOMATIC filter cleaning and HEPA filtration. Filter cleaning is carried out by internal vibrations and reverse flow.
