MAC 10® IQ LAF Fan Filter Unit


Programmed for low flow and low sound applications The MAC 10® IQ LAF is the world’s first smart fan filter unit to take advantage of torque programming to achieve low airflow set-points using a microcomputer-controlled ECM motor. This was previously not possible with units programmed for constant airflow. With the advancement in ECM motor technology, we are able to provide a fan filter unit that delivers low airflow and maintains airflow within 10% for up to .2” WC changes in static pressure. The ability to adjust to limited changes in static pressure gives the fan the ability to supply reduced airflow for critical applications requiring low flow and low sound.

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® LAF FFU uses a combination of ECM motor technology with Envirco’s unique baffling system and forward curve fan to make it intelligent and energy-efficient. The electronically commutated (ECM) motor with internal micro-computer provides low energy consumption high performance and long motor life. The LAF utilizes Envirco’s VE5 baffling technology, offering you versatility in your design that are a MAC 10® family benchmark.
