Extra low watts, sound, and profile
The Envirco® LEAC2 fan filter unit is the first (FFU) with low watts, low profile, and high airflow. The MAC 10® LEAC2 2 x 4 ft (600 x 1210 mm) provides one of the lowest power consumption levels of any FFU in the industry. Running at only 208 watts @ 90 fpm, the unit uses less energy than traditional FFUs and reduces operating costs. The MAC 10® LEAC2 standard model maintains a low profile, measuring less than 13" (318 mm) tall. The MAC 10® LEAC2 comes standard with the filter integral with the unit housing. Room-side replaceable filters and motor blower removable from room-side are available.
