High Efficiency Particulate Air (HEPA) Filter

Clean Filter Industries Pvt Ltd (CFI) offers a range of HEPA Filter. The acronym HEPA stands for High Efficiency Particulate Arrestance. A true Hepa is also known as an absolute filter because of its efficiency. For a filter to be called a true Hepa it must retain and filter out all particles from the air that passes through it down to 0.3 microns in size at an efficiency rating of 99.97%. The efficiency of a true Hepa does not decrease because during its life, it actually increases. For a filter to be labelled “True Hepa” it must be certified 99.97% efficient in capturing 0.3 microns respirable-size-particles (RSP) according to the US Military standard MIL-STD-282, commonly known as the DOP test. True Hepa filtration is recognised as one the most efficient air filtration methods known and proven to remove airborne particles down to 0.3 microns and are used for the purpose of absolute filtration in nuclear installations, toxin research laboratories, pharmaceutical industry, clean room systems, laminar flow working bench, hospital sterile area, space application, manmade fibre industry, food processing zone, biological centres and many other areas. Construction: absolute HEPA filters are made out of 100% water and fire-resistant imported micro glass fibre paper. The paper is pleated and the pleats are separated by super fine corrugated aluminium foil and finally fitted in an aluminium frame. Epoxy-based adhesive is used all over from the inside for effective sealing of gaps, and also neoprene-sponge rubber gasket is provided on the flanges to effectively seal the construction from the outside.
