Nilfisk main filters are ideal for trapping impurities in vacuum cleaners and preventing the residue from blowing back into the environment. These units feature an oversized design to provide maximum surface area for filtering, which when coupled with the vacuum's powerful suction also maintains an optimal airflow rate. The anti-static filter models allow conduction and dissipation of static charge build-up during the filtration process, thereby providing a spark-free operation. These filters are capable of delivering a maximum efficiency of 99.7 per cent for particle sizes down to 1.5 microns. Choose from a wide range of these industrial vacuum filters available in polyester, cloth, paper and glass fibre variants on Raptor Supplies.
