ATEX Certified Air Powered Vacuum cleaners
99.995% filtration efficiency
Each model in the range is equipped with three stages of filtration on the negative pressure (suction) side of the motor. The first stage is a sealable disposable microfibre bag, the second is a high-efficiency filter assembly using a filter medium that is specially designed as a pre-filter material for HEPA (High Efficiency Particulate Air) filters. The third stage is an oversized HEPA cartridge filter (H14 as standard) housed in a sturdy replaceable module. Every Type H vacuum cleaner is individually DOP tested on calibrated test equipment to achieve a filtration efficiency of greater than 99.995% up to 0.6 microns.
