The DF FIX 75 Z2-Z22 is a fixed industrial vacuum with a three-phase fan that can be used for medium-sized centralized systems. Inside the vacuum cleaner, there is a large surface filter in antistatic polyester (45,000 cm2), M class certified with a filtration efficiency of 1 micron, to suck up electrostatically charged dust in total safety. In addition, it is possible to install an H14 filter for situations that require the suction of the finest dust. To clean the filter there is a very effective manual filter cleaning system as standard. Thanks to a lever outside the filtering chamber, the operator is able to shake the filter and deposit the dust directly in the collection container. On request, it is possible to install an automatic piston filter shaking system or a counter-current filter cleaning system. The unit is equipped with a release container on wheels with a capacity of 175Lt in AISI 304 stainless steel.
