The series 3907 /18 ATEX are the right I-Vacs for the industries who have to work in potentially explosive atmospheres as the Directive 94/9/EC and 99/92/EC state. This vac offers high performances while still being extremely manoeuvrable and versatile. It mounts a Threephase Side Channel Blower that guarantees a silent and continuous running. The suction unit is controlled by an electrical equipment with a star-triangle starting as standard, housed in the rear casing. It gets a large Stainless Steel container and an Antistatic Star filter in “L” class as standard.
