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 thermic switch cuts off the motor in case of overheating The control board is placed in a safe position at the back, and include two independent ON and OFF switches (protection IP65); a vacuum indicator enables constant checking of the suction performance, and detecting possible clogging of the filter.
过滤系统 Filter unit
由聚酯制成的过滤网安装和保护在钢铁过滤桶里，以口袋形状裁剪，从而增加了过滤网的表面（20000 cm2）并且具有高过滤功效（3 微米）。手动震尘器使用户上下摇动来清洁过滤网，让大部分灰尘掉落保持过滤网干净，这样能够延长它的使用寿命和确保吸尘功效。前部铝质以印模压铸的吸尘接口（直径80 毫米）放置在过滤网下面，因此不用取出或更换过滤网就可以同时灰尘和固体、液体等物质（后者只能在集尘箱容积的范围之内）。过滤筒内一个气旋焊接的传输带直接传送大部分的灰尘，并能保护过滤网不被割破或撕开。
The filter is placed and protected inside the steel filter chamber; the filter is made of polyester, tailored with pockets in order to increase the filter surface (20.000 cm2), and has a high filtration efficiency (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 aluminium die-cast suction inlet (?80 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.
集尘系统 Collection unit
被吸的物质都落在带轮子的集尘箱里（100 升），从而可以方便安全处理被吸的物质。如果需要，可以直接收集到垃圾袋里。
整个机器安放在坚固钢铁底盘上，带两个旋转轮子，其中一个有制动装置，所有金属部件都是环氧喷漆的。
The vacuumed material is placed inside a drop-down bin mounted on wheels (100 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.
