Three-phase industrial vacuum cleaners that are powerful yet easy to move, for applications requiring frequent movements in reduced spaces. They are fitted with a three-phase co-axial turbine in aluminum. Reliable, and designed for continuous heavy-duty use, they are recommended for car washes and for ceramic, chemical, mechanical and textile sectors. They are ideal for removing dust, flours, chips and liquids of varying densities. The SS version is fitted with a radial filter as standard, and is referred to as a vacuum cleaner for dusts, while the S version can work on both dusts and liquids. Upon request, class M and heatproof filters can be installed on both models.
