DG HD Z20/21 - II 1/2D Atex internal zone 20 and external zone 21 certified industrial vacuum

The most powerful Atex certified vacuum cleaners in the range when it comes to sucking up dust, solid and liquid in Atex zones 21.


Vacuuming potentially explosive dusts in zone 21 hazardous areas can create an even more perilous situation inside the industrial vacuum cleaner, where the extracted dust is moved and collected. Zone 20 certification of the interior of the vacuum chamber, the AISI304 stainless steel container and additional H14 absolute filter eliminate this risk and guarantee maximum suction performance.
