The MAC 10® LEDC FFU can help provide opportunities to earn LEED points with its many energy-saving features. Note: LEED (Leadership in Energy and Environmental Design) is the rating system of US Green Building Council by which building designs are certified.

By taking advantage of a unique combination of EC motor technology with Envirco’s proprietary baffling system and backward inclined fan, the LEDC tops the industry in energy efficiency. Its electronically commutated (EC) motor with internal microprocessor offers high performance and delivers long motor life with energy consumption rates as low as 90W @ 90 fpm. Utilizing Envirco’s experience in FFU development, the LEDC also features low sound levels of 52.3 dBA, which are a MAC 10® family benchmark.

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