Founded in 1985, Pure Air Systems offers one of the most complete line-up of HEPA air filtration systems anywhere. In fact, there are now only three companies in the world, including Pure Air Systems, that offer fan-powered, high-performance true HEPA filtration systems in the world.
PAS currently uses variable speed drive motors in all of its filtration systems and that now includes the HPS series portable units. Unlike the older style induction motors, the variable speed drive motors can be programmed to run at any speed and are capable of ramping up if the pressure drop across the HEPA filters increases. This allows for a constant flow of air ( measured in CFM ) through the filtration systems over the life of the HEPA filter.
The all-metal housing units also include a prefilter and carbon filter along with the scanned HEPA filters. There are three base units, the 600HS, 1200HS and 2000HS units along with the HPS portable series. The housings for the base units are split into two sections, with one section containing the blower/motor and the other section containing the filters. By modifying the sections we can offer straight through units, or left or rignt 90 degree angles and also change the type of filters that are put into the units. This design technique allows us to offer a unti to fit any configuration whether the units are installed as along with existing duct work or as stand alone systems.
