MAC 10® IQ Fan Filter Unit


The first Fan Filter Unit with a built-in brain. The MAC 10® IQ is the world’s first smart fan filter unit. With its microcomputer-controlled DC motor, the MAC 10® IQ dynamically adjusts itself to maintain the set airflow, compensating for changes in static pressure, filter loading or other local conditions. Competitively priced, the MAC 10® IQ offers low sound, low energy consumption, and a low profile with high performance and built-in intelligent control. While Envirco® has introduced a variety of proprietary products, one of its most successful continues to be the MAC 10® family of fan filter units (FFUs). MAC 10® FFUs are used worldwide for a variety of critical clean air applications. The novel MAC 10® IQ FFU uses a combination of DC motor technology with Envirco’s patented baffling system and forward curve fan to make it intelligent and energy-efficient. This unique combination takes advantage of Envirco’s expertise in FFUs and energy efficiency of EC motors. The electronically commutative (EC) motor with internal micro-computer provides low energy consumption (235 W @ 90 fpm (0.45 m/s)), high performance and long motor life. The IQ utilizes Envirco’s their unique baffling technology, offering low sound levels that are a MAC 10® family benchmark.

Constant airflow. Unlike conventional induction motors, the EC motor regulates itself by automatically adjusting its torque and speed. Each MAC 10® IQ includes a visual control unit which provides a constant air volume of 250-660 CFM over a wide range of static pressure. The MAC 10® IQ maintains airflow so constantly and consistently that the need for future balancing is greatly reduced. The correlated velocity feature of the visual control unit provides infinite control and fine tuning capabilities for each FFU. The MAC 10® IQ efficiently and easily maintains set clean room airflow velocities that meet IEST Recommended Practices. With its unique constant airflow feature, the MAC 10® IQ is also an ideal component for mini-environments.
