Using HEPA filtration systems as air moving boosters is fairly common and in most cases necessary. If you have a multiple number of pick up points from which you want to remove contaminated air you need to understand the concept of air flow resistance or pressure drop.
When moving air through any type of duct system you have to take into consideration the resistance of air flow through the duct especially if it is flexible duct and you have some 45 degree and 90 degree bends. Air flow resistance is measured in inches and the higher the number the greater the resistance the larger the horsepower has to be on the motor/blower system that is moving that air from one point to another.
If you have any type of air filtration device in the air flow system that being used to remove the contaminants you also have to take into account the static pressure loss across that filter as well. If it is a HEPA filter you have a significant pressure drop which needs to be added into the total line loss when designing the blower/motor system.
Pure Air Systems has been making fan powered HEPA based air filtration systems since 1985. They use variable speed drive ECM motors on all their systems that adjust automatically by speeding up as the pressure drop across the HEPA filter increases.
Since Pure Air Systems makes HEPA filtration systems that are fan powered they can be used as boosters for moving air through an entire ducted system to maintain the proper carrying velocities through the ductwork even as the HEPA filters load up.
It takes a lot of power to move air through ductwork and a filter so using the PAS systems makes sense. The models range from 600 CFM to 2000 CFM air flow capability using 1/3, 3/4 or 1 HP ECM motors. PAS is one of the few companies in the world that make high end, fan powered, commercial grade HEPA air filtration systems that can be used as stand-alone systems or in conjunction with a ducted HVAC system or commercial air handlers.

About the Author: Don Musilli
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.
