MAC 10® IQ Fan Filter Unit


The MAC 10 IQ® is the world’s first smart fan filter unit. With its microcomputer-controlled EC 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. Unlike conventional induction motors, the EC motor regulates itself, automatically adjusting its torque and speed to provide a constant air volume of 250-660 CFM over a wide range of static pressure. The MAC 10® IQ maintains airflow at such a constant rate that the need for future balancing is greatly reduced. A Universal Control Card with three different control modes, provides installation versatility by allowing the FFU to be controlled via a MODBUS RTU network, an analog 0-10 VDC control signal, or by adjusting the onboard potentiometer.

The MAC 10® IQ FFU uses a combination of EC motor technology with Envirco’s unique baffling system and forward curve fan to make it intelligent and energy-efficient. The electronically commutated (EC) motor with internal micro-computer provides low energy consumption (235 watts at 90 fpm (0.45 m/s)), high performance and long motor life. The IQ utilizes Envirco’s VE5 baffling technology, offering low sound levels that are a MAC 10® family benchmark.
