Suction unit: Suction provided by unit of side channel blower type, with direct coupling between the fan and the motor shaft and no transmission system. It is thus completely maintenance free, fit for round-the-clock 24 hours duty, very silent and provides outstanding suction performances; a pressure relief valve protects the motor from overheating in case of clogging of the filter or continuous duty at high depression. A diffuser filter reduces the speed and noise of the air on the exhaust outlet.
Filter unit: The filter is placed and protected inside the steel filter chamber; the star filter is made of polyester, providing a filter surface of 20.000 cm2 and a high filtration efficiency (Class L, 3 micron). A manual filter shaker enables the user to clean the filter efficiently, by a vertical shaking movement, so as to detach most of the dust and maintain the filter clean, in order to increase its life and maintain the suction performance of the machine. The frontal aluminium die-cast suction inlet (Ø80 mm. diameter), placed below the filter, makes it possible to vacuum at the same time dust, solid and liquid material (the latter only within the capacity of the container), with no need to change or take out the filter.
- The vacuumed material is placed inside a drop-down bin mounted on wheels (50 litres capacity), which makes it possible to dispose easily and safely of the sucked material, that can be collecting directly into a plastic bag.
- The vacuum is mounted on a sturdy steel chassis with two pivoting wheels, one of which with brakes; all metal parts of the vacuum are epoxy painted
