DM3 AIR EX

AIR OPERATED IDUSTRIAL VACUUM CLEANER
With EXPLOSION PROOF ATEX CERTIFICATE for Zone 1, 2, 21, 22

ATEX – Explosion Proof compliance

The explosion proof conformity of the machine is certified according to use in Zones classified as subject to risk of explosion, as Zone 1 and 2 (presence of explosive gas) and 21 and 22 (explosive dust).

 

Suction unit

The suction is provided by two powerful Venturi suction units, (using no electric or mechanical components),  operated by an external compressor (not included) and placed inside a sturdy steel casing. The control board includes an air pressure gauge (to check the pressure of the incoming air supply) and vacuum indicator, useful to detect possible clogging of the filter. Two handles placed on the sides enable an easy lifting and removal of the suction head, for possible inspection or replacement of the underlying filter.

 

Filter unit

The filter is placed and protected inside the stainless steel filter chamber; the polyester star filter provides a filter surface of 20.000 cm2, and high filtration efficiency (class L, 3 micron). and is conductive in order to avoid sparks from static energy. 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. The frontal aluminium die-cast suction inlet (Ø80 mm. diameter), placed below the filter, makes it possible to vacuum at the same time dust and solid, with no need to change or take out the filter.

 

Collection unit

The vacuumed material is placed inside a stainless steel drop-down bin mounted on wheels (55 litres capacity, optional 100 litres), which makes it possible to dispose easily and safely of the sucked material, if need be collecting it directly into a safety seal-off single use plastic bag with lid, suitable and certified for collection and disposal of hazardous dust
The vacuum is mounted on a sturdy steel chassis with antistatic wheels and earth chain. All metal parts of the vacuum are electrically grounded and made conductive, in order to avoid sparks from static energy.
