HEPA Filter is a high efficiency cartridge filter of industrial
vacuum cleaners which can hold the fine particles up to 0.3 microns and make
the filtration process up to 99.97% efficient. This filter is installed as a
secondary filter (safety) on the top of the main filter of industrial and semi
industrial vacuum cleaners and it can be very useful in cases where the
particle size distribution is very tiny. The HEPA filter is the final stage of
filtration and the use of HEPA filter is essential when fine powder is
collected or the environment is the smallest proportion of pollutant particles.
The HEPA filter is also used for collecting toxic and hazardous dust and it is
necessary to install a class H filter on vacuum cleaner.
HEPA is abbreviation of High Efficiency Particulate Air. The HEPA
filter is composed of highly interlaced fiberglass fibers, which tends to trap
fine particles. Particles with dimensions of 0.3 microns are more suspended in
air than other particles with smaller or larger sizes and pass through common
filters, so filters in the H class are based on filtration of these particles. The
H class filter (HEPA) will be used with vacuum cleaner in various industries
such as pharmacy, food industry, chemical industry, rubber, electronic
manufacturing industry, cement industry, construction industry and in any other
environment that is considering any kind of powder materials and fine dust. The
HEPA filter guarantees user safety in the work environment and does not allow
returning collected particles and materials to the environment.
