Mod. DG 300HD
INDUSTRIAL HEAVY DUTY WET & DRY VACUUM CLEANER
SUCTION UNIT
The suction is provided by a suction unit of the 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 safety thermal switch cuts off the motor in case of overheating.
The control board is placed inside a sturdy metal casing, in a safe position at the back, and include two independent ON and OFF switches (protection IP65), a safety emergency stop button and a star-triangle soft start device. A vacuum indicator enables constant checking of the suction performance, and detecting possible clogging of the filter. Two pressure relief valves protect the motor from overheating in case of clogging of the filter or other blockings in the suction system.
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 polyester star filter provides a filter surface of 120.000 cm2, and high filtration efficiency (class L, 3 micron).
An automatic filter shaking system, operated by an installed compressor, enables to clean the filter efficiently and constantly, by a vertical shaking movement (the frequency and length of which can be adjusted by means of a timer), so as to detach most of the dust and maintain the filter clean, in order to increase its life and improve the suction performance of the machine. The tangential aluminium die-cast suction inlet (Ø120 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.
A cyclone welded inside the filter chamber conveys most of the dust directly in the container, and protects the filter from cutting or tearing.
COLLECTION
The vacuumed material is placed inside a drop-down bin mounted on wheels (220 litres capacity), which makes it possible to dispose easily and safely of the sucked material, if need be collecting it 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.
