Founded in 1985, Pure Air Systems has been manufacturing commercial grade, fan powered, HEPA filtration systems with a wide range of performance. Beginning with their 600HS Plus, PAS has been adding variable speed motors to their line up since 1999 and now offers a new variable speed motor for their HPS 250 portable unit. This unit. first introduced in 2000, used a four speed EBM motor/blower unit and offered air flows from 50 CFM to 250 CFM and immediately became a major addition to the product line. 

The new variable speed motor now offers the same advantages it provides in the models, 600HS, 1200HS and 2000HS units. The ability to have finite control over the air flow to exactly match the needed performance of the unit depending upon the application. Since the portable unit is most often used in a smaller environment such as a laboratory, clinic, semi-clean room or medical facility, the control of speed also allows for control of the noise level. In addition, using the new motor allowed PAS to use a fan blade design that has better air flow and performance over the range of the life of the HEPA filter as well as minimizing fan noise. And like the variable speed motors used in the other systems, this one can be programmed to automatically ramp up and maintain the same speed even as the HEPA filter loads up and the static pressure increases.

This new unit will be available soon. For more information on this updated unit and the complete line of HEPA and Carbon based air filtration systems please go to our website at:  http://pureairsystems.com    or call us on our toll-free number at: 800-869-8025.
