Introduction to Industrial Pre Filters

AXENIC SYSTEMS (established in 1995) is one of the leading companies engaged in manufacturing and supplying Industrial Pre Filters to carry out the decontamination process in a cleanroom. Our finest quality Industrial Pre Filters are wisely constructed at our factory, tested at different parameters then dispatched to the client’s site. We have an in -house facility of design, production and installation of Industrial Pre Filters for laboratories, clean rooms and manufacturing areas. 

Industrial Pre Filters are air filters (commonly Coarse) used before other filters (mostly fine or HEPA) as a way of recollecting solid particulates that are present in the air, thus maximizing the productivity of the air filtration system. The primary pre-filters perform the first filtration, retaining the largest particulates, thus protecting the next stage of filters in the filtration system, enhancing the performance and stability.

Another vital role of pre-filtration is its use as an optimization approach in the filtering procedure and extending the useful life of other filters, as they will receive a lower particulate load, which will result in better durability and greater particulate retaining capacity as well. The sequence and optimal of filters for use as pre-filters will depend a lot on the application for which the air treatment is anticipated, as well as the segment for which it is serving. Coarse filters are generally used as Pre-filters for fine filters and fine filters as Pre-filters for HEPA absolute filters. But there are particular applications, where there may be more filters used than those mentioned.

Use of Pre-filters in cleanroom environments

In critical surroundings like clean rooms, the use of pre-filters is extremely essential. In some of these procedures, even more than one pre-filter is used to assure excellence in filtration.

In these environments, the Pre-filter maintains the coarse particles coming from the outer air consumption for restoration and pressurization and the return of air from the clean room, the fine filters maintain all kinds of particulates while the absolute HEPA captures the micro particles. Using the fine and coarse filter as a Pre-filter increases the lifespan of the absolute HEPA filter. Filters in cleanroom environments can be installed in HVAC Systems equipment, in ducts in special filter boxes and also in terminal filter boxes.
