MEP Ex - Atex dust collector filter

The assurance of safety, for dust with explosion hazard.

MEP Ex filters belong to the category of ATEX extraction equipment: these are state-of-the-art dust extraction equipment designed for the abatement of explosive-risk dust. These filters find application in numerous areas, including for example:

• Industrial or handicraft activities involved in metal processing and finishing, with a focus on the production of light metal dusts, such as aluminum dusts.
• In the pharmaceutical industry, the production of highly flammable light dusts is well known, the hazard potential of which must be contained by the adoption of ATEX industrial dust collectors, certified for the degree of risk of the dusts (see below for the risk classes in which ATEX dusts are currently classified).
• In the agri-food industry, the processing of flours of all kinds involves a number of risks related to the flammable potential of some of them. Again, the risk can be effectively contained by dust extraction and filtration.
• Wood processing requires the adoption of special extraction equipment for wood dust, which requires ATEX certification due to the natural flammable note of these dusts.

Dust and explosion hazards

Dust explosions are extremely violent and develop with great speed. In most cases they cause severe damage to equipment and long plant restoration times, but sometimes there can also be damage to people and property.

Dusts are divided into hazard classes St. 1, St. 2, St. 3; the higher the class number, the more violent the explosion. NEDERMAN has developed industrial dust extractors with special filters, suitable for all classes, with which the explosion force can be controlled, damage minimized, and the best possible protection towards people and property achieved.

Minimizing explosion damage

These Atex MEP Ex filters operate exactly like standard filters but the filter body is reinforced. The filters are also equipped with bursting discs that have no mechanical parts. If the pressure inside the filter due to an explosion exceeds a predetermined value, the burst disk breaks and the pressure wave is vented to a safe area.The explosion is thus controlled and the resulting damage is minimized.

Approved and certified

MEP Ex filters are designed and manufactured according to German VDI 3673 standards and are ATEX certified.

As all SO.TEC dust extraction systems, MEP Ex filters feature a compact design that minimizes space requirements while still providing maximum extraction and filtration efficiency. The small size allows dust extractors to be installed close to where the dust is produced, thereby reducing energy consumption during extraction, the length of piping and thus the overall cost of installation.
