Envirco products

A Second Generation FFU: The MAC 10® LEDC features the most control options and the most versatile control system available on the market today, while topping the industry in energy efficiency. The MAC 10 LEDC comes standard with the filter integral with the unit housing, while roomside replaceable filters, motor blower, and now controls are available. Roomside Replaceable Controls (RSRC): Roomside replaceable filter, motor assembly, and control card are now available for the MAC 10 LEDC. With the RSRC, the control card is replaceable through the top and roomside. FFUs can be auto programmed with selection of the proper controller. Filters are shipped loose for easy access and replacement.

A Second Generation FFU: 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). We add to this industry’s leading line of products a second generation FFU, the MAC 10® LEDC, which features the most control options and the most versatile control system available on the market today.

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.

ENVIRCO developed the MAC 10 RFAC for applications requiring negative pressure reverse flow FFUs. The RFAC is designed to pull contaminated air from the intake side of the filter, filter the air, and then exhaust it outside of the area required. The most common negative pressure applications are for modular cleanrooms, cleanroom garmenting rooms, healthcare contamination control, cleanroom workstations, clean workbench enclosures, and associated air hoods. The RFAC is a versatile FFU capable of being used in ceiling grids, installed inside equipment, or wall-mounted. Alternatively, the RFAC can be designed into an AC-powered mobile cart to function as a portable negative pressure FFU.

Extra low watts, sound, and profile. The Envirco MAC 10 fan filter unit, was the first (FFU) to combine low sound, low watts and a low profile. Measuring only 51 dBA, the MAC 10 Original Standard (2 ft x 4 ft [600 mm x 1,210 mm]) provides one of the lowest sound levels of any FFU in the industry. Running at only 310 watts @ 90 fpm, the unit uses less energy than traditional FFUs, lowering operating costs. The MAC 10 Original maintains a low profile, measuring less than 13” (330 mm). MAC 10 Original comes standard with the filter integral with the unit housing, requiring the unit to be removed from the ceiling grid to replace the filter. The RSR unit has the filter sealed to the unit using the knife edge/gel seal construction, allowing the filter to be replaced from the roomside. The RSRE unit has the added feature of allowing the motor blower and filter to be replaced from the roomside.

Envirco introduces the Next-Gen cleanroom monitoring and control system products that have the ability to automatically monitor and report errors found on any fan filter unit. System level sensors can be monitored (i.e. particle counters, pressure transducers and airflow sensors) by adding them to the network through Envirco’s Interface Modules. Our total control systems support digital, high-speed, and analog I/Os for Alarm output, remote standby or BMS override.
