MAC 10 Original

The Envirco® MAC 10 is the original modular, self-powered, high efficiency particulate air (HEPA) filter ceiling grid module. Since its debut, it continues to lead the way with constant improvements and innovations. Known for being the quietest modular ceiling unit available, the MAC 10 is built to last with quality construction and innovative, patented technology.

MAC 10 HEPA Filter graphicThe MAC 10’s modular design fits conveniently into 2’x4′ T-Bar drop ceilings. The standard MAC 10’s low profile of less than 13″ also permits installation into tight ceiling spaces. Plus, threaded corner inserts provide convenient attachment of seismic hangers. In addition to the standard MAC 10 2’x4′, there are other MAC 10 sizes to choose from. These sizes accommodate various ceiling layouts and permit convenient sprinkler penetrations.

Now Even Better

We’ve beat our own record again. Now the standard MAC 10 2’x4′, with optional speed control, tests below NC 45 at 51 dBA measured 30 inches from the filter set at the rated flow of 90 FPM.*

It is the only low profile fan filter unit that has achieved such a low noise level at 90 FPM. That’s because the patented VE5 baffling system gives the MAC 10 uniform airflow and absorbs sound, contributing to its low noise levels.

Only the MAC 10 is a MAC 10. No other fan filter unit is quite the same. The patented technology and quality construction make it the best value available worldwide.

*Digital control or Solid Speed Controller option required.
