Pure Air Systems has been making commercial grade, fan powered HEPA air filtration systems since 1985. They are one of three companies in the world that provide this type of filtration systems. PAS makes a number of models of HEPA systems that range from 600 CFM to 2000 CFM all using variable speed drive motors. Their portable system, the HPS series was introduced around 1992 and has since gone through a number of refinements. It was the only HEPA unit in the line-up that did not use a variable speed drive motor. In stead, it used a 4 speed motor from EBM. 

Coming this year, PAS will be fitting the popular portable HPS unit wiith it’s own variable speed drive motor. This will allow for a CFM range from 25 CFM up to 250 CFM in 1% increments. In addition, the new motor will be designed to maintain the same speed/cfm rating even as the pressure drop increses across the HEPA filter.And likes the original version, the new HPS unit will have a prefilter,carbon filter and a true 99.99% scanned HEPA fitler as standard equipment.

The portable HEPA unit has a wide range of applications and is very well suited fror the laboratory environment as well as small confined areas requiring HEPA filtraiton in both a positive or negative room application. The all metal housing and rugged construction make this one of the best portable HEPA systems on the global market.

My name is Don Musilli. I started Pure Air Systems in 1985 and then sold it in 2006. I continue to consult for PAS and write their blog and control their Twitter account. I also, on occasion, make changes to the website. The company is now almost 26 years old and has been a major player in offering commercial grade, high performance HEPA and Carbon based filtration systems for the commercial, institutional, industrial and residential markets.

I currently reside in Englewood, Florida where I write blogs and do social media marketing for a number of clients.
