MTL352 DS AIR EX

AIR OPERATED INDUSTRIAL VACUUM CLEANER
(With EXPLOSION PROOF ATEX CERTIFICATE for areas 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 vacuum cleaner MISTRAL 352 DS AIR EX is an explosion proof compressed air vacuum cleaner powered by one powerful Venturi suction unit, (using no electric or mechanical components), 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 enable an easy lifting and removal of the suciton 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 antistatic (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 (35 litres capacity), 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 filter chamber and collection container are made of stainless steel (AISI304 type); 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.
