Since 1985 when Pure Air Systems first came out with its fan powered, commercial grade HEPA filtration unit, the systems have been used for all types of air quality problems and co-joined with other equipment proving its all around capabilities. Because the PAS HEPA systems use highly efficient yet powerful fan motors these units are like WD40, they work on everything.

When you think about an air filtration unit, especially a HEPA based unit, you automatically think the system is used strictly as a filtration device. While that may be true for the majority of HEPA filtration units, the PAS systems can be used as a small air handler, pressurization unit, stand-alone mobile unit, in conjunction with any HVAC unit, and as an all Carbon unit.

The PAS line of fan powered HEPA and Carbon based systems were originally designed to be installed on the return air side of any forced air ducted heating/cooling system. In this capacity they can clean all the air in a house or office area up to 48 times per day.  They can even introduce small amounts of outside filtered fresh air through the unit to assist in pressurizing the environment and reducing the levels of CO2 in heavily occupied facilities.

In applications where a small amount of heating or cooling (1 to 2 ton capacity) is required, the larger, more powerful PAS HEPA systems can be mated with a cooling coil or electric heating element so that the system will move the heated or cooled HEPA filtered air through a small area and provide comfort control with filtration all in one unit.

The PAS HEPA Systems can be used in any medical, electronic assembly or critical high tech environment to both filter the air to meet the clean room requirements as well as pressurize the room to minimize any in-leakage of outside air. In addition, the unique variable speed dual voltage digitally controlled motors used in the PAS unit allow for finite air volume control to maintain proper air flow and pressurization when needed.

The ECM variable speed motors are rated 120/240 volt, 50/60 Hz and will operate anywhere in the world. This means remote areas when a HEPA filtration type of system is required can be accomplished using the PAS HEPA filtration systems. The units can also be installed in mobile trailers or wheeled mobile units like ambulances, mobile labs, mobile medical units and mobile HAZMAT units.

When an application calls for removal or reduction of a specific odor or gas, the PAS HEPA units can be easily converted to all Carbon units to effectively handle the gaseous problem. This conversion can even be accomplished in the field.

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.
