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.

Additional Information

N/A Performance and Innovation
The LEAC2 comes standard with a solid-state speed control and will operate against high external static pressure to provide superior filter life. By taking advantage of a unique combination of motor blower technology, along with Envirco®'s proprietary baffling system, the LEAC2 delivers uniform airflow over a wide range of cfm.

Envirco® MAC 10® FFUs are used worldwide for a variety of critical clean air applications. Learn more about how you can benefit from the LEAC2 in your next critical room application.
