Low Sound. Low Watts. Low Profile.
Industry-Leading Clean Air Performance
MAC 10® Original Fan Filter Unit
The Envirco® MAC 10® Original Fan Filter Unit (FFU) was the first in the industry to combine low sound, low energy usage, and a slim profile. Measuring only 51 dBA and operating at just 310 watts @ 90 fpm, it delivers quiet, energy-efficient performance that lowers operating costs. At less than 13” tall, it also provides one of the lowest profiles available.
The MAC 10 Original comes standard with an integral HEPA filter, requiring unit removal from the ceiling grid for filter replacement. The RSR model allows filter replacement from the roomside with a knife edge/gel seal construction. The RSRE model goes a step further, enabling both the filter and motor/blower assembly to be replaced from the roomside.
