Filters

N/A Aluminum framed High Efficiency Particulate Air (HEPA) type, with a minimum efficiency of 99.99 % at 0.3 micron, aerosol challenged (zero probed).

Motor/Blower Assembly

N/A Direct drive, continuous duty motor with sealed-for-life bearings and inherent overload protection. The blower assembly is electronically (dynamically) balanced and is designed to provide rated airflow through a 50 % increase in initial static pressure.

Additional Information

N/A Fewer components mean lower installed costs. With use of the MAC 10® LEDC 4 x 4 unit, additional savings are captured in the ceiling plenum because less grid is required and fewer electrical connections are needed. Even better, this model also provides a lower sound level than most competitive 2 x 4 fan filter units.
