Solid, capable and powerful, the three-phase industrial vacuum cleaner is equipped with turbines ranging from 2.2 to 5.5 kw, is characterized by large filter surface and containers between 50 and 100 lt. This vacuum cleaner, which in Delfin's range is represented by 4 models of the DG EXP line, can also be used as a suction  unit in small centralized systems, in combination or not with filtering preseparators or hoppers.

The real strength of this type of industrial vacuum cleaner is its reliability. In fact Delfin equips its industrial vacs only with Italian, German or American side channel blowers, which ensure outstanding performance, even in continuous and very heavy applications. The side channel blowers used, moreover, are suitable to work continuously and can work without problems even 24 hours 24 (in these cases it is recommended to adopt a safety valve that protects the turbine from overheating, allowing it to virtually work to infinity).
