Since it’s beginnings in 1985, Pure Air Systems has strived to push the limits of available technology to continue to improve its HEPA based air filtration systems and offer more operational flexibility for its commercial and residential customer base. During the early years of operation PAS used the common induction motors for their systems. These were limited to one speed and limited the amount of volume adjustment in the filtration systems. 

In 1999, GE produced a new variable speed drive motor known as an ECM motor. This motor was a total departure from the wound copper induction motors as it use magnets for its drive mechanism. It could run forward or backwards and could be controlled digitally to operate in 1% increments from % of volume to 100% of volume. PAS was one of the first companies in the US to test this motor and eventually incorporate it into all of our systems. Additionally, these motors could be used in 120/240 50/60 Hz applications, making them perfectly suited for use overseas where most electrical systems are 240 volt/50Hz. This allowed us to open up new markets in Europe and Asia.

In the past year the the 2nd generation of these motors now allows us to operate them using Bluetooth apps on any smart phone. This gives the customer complete control of the HEPA systems no matter where they are located. And, the new motors can be programmed for different HP requirements from 1/3 HP up to 1 HP and run at full speed even when the pressure drop across the HEPA filters gets as high a 3.3 inches of static pressure.

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.
