Certified in accordance with the EU-wide binding ATEX Directive 2014/34/EU by the independent and renowned testing institute IBExU, the NT 75/1 Me Ec M Z22 safety vacuum cleaner is suitable for the removal of combustible and other dusts of dust class M in explosion-risk areas of Zone 22. The brushless EC motor ensures a lifespan of 5,000 hours. The fully grounded design and the associated conductive accessories effectively prevent electrostatic discharges. Thanks to the 75-liter container made of stainless steel and the robust chassis with adjustable push handle, large quantities of dust, coarse dirt, or liquids can be comfortably removed from the hazardous area and disposed of safely. The NT 75/1 Me Ec M Z22 features the Wet & Dry flat-fold filter of dust class M, which guarantees a dust retention rate of 99.9 percent and is also suitable for vacuuming liquids. If needed, the wet/dry vacuum cleaner is also approved for use without a filter bag or disposal sack – for this purpose, the optionally available "Wood" candle filter is designed specifically for vacuuming fibrous dusts without a filter bag.
