Single-phase vacuum cleaner
35 L, 1.5 kW | MTL 150 ECO / M Delfin srl

Suction unit
The suction is provided by a suction unit of the side channel blower type (working at 230 volt single phase), 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; a safety 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), and a safety emergency stop button; a vacuum indicator enables constant checking of the suction performance, and detecting possible clogging of the filter. 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 polyester filter provides 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 . A sturdy 80 mm. Ø suction inlet (reductions available down to 40 mm.) enables to suck up the material in a position below the filter, thus reducing its impact and clogging effect.
