Air Filtration 33 Years Later
Pure Air Systems has been in the Air Filtration business since 1985 and has successfully kept its position in the HEPA based air filtration market by continuing to make advancements in its product line.
Since its’ beginning, Pure Air Systems has pushed the envelope in bringing HEPA based air filtration technology to the residential and commercial markets. It was the first company to develop the partial by-pass concept allow us to attach very large, fan-powered true HEPA systems to any forced air ducted heating/cooling systems.
In the later part of the 1990’s we were one of the first companies to use the new variable speed drive, ECM motors from GE. These motors were digitally controlled and they were rated 120/240 v 50/6h0Hz. So we could sell our filtration systems anywhere in the world. This opened up a whole new market for Pure Air Systems.
In 2001 we began working on the HPS portable HEPA unit. This small HEPA system used a four-speed EBM combination blower/motor and had a 12″ square housing that was 21″ long. It was designed for Laboratory applications as well as small rooms and offices. This was the first portable to use a scanned HEPA filter rated at 99.99% at 0.3 microns. It also included a carbon media filter like all of our other systems utilized.
The addition of the ECM motors also allowed us to develop some digital speed controllers that would give our customers the ability to use the systems in a stand-alone configuration and control fan speed from 1% to 100% in 1% increments. This opened up the door for applications where customers wanted to control the air flow for positive and negative room conditioning or where the application required a specific volume for proper ventilation or contaminant capture.
Pure Air Systems continues to use all metal housings for their Air Filtration systems and these powder-coated housings are designed to last up to 20 years and longer. We still have systems in the field that have been running since the late 1980’s.
