Envirco Introduces MAC 10 Original ™ Control System
for Cleanroom Control

Albuquerque, NM, August, 2004 – Envirco Corporation, a division of Fedders Engineered Products, has developed, under the Envirco brand, MAC 10 Original ™ Control System to direct the flow of centralized air in small to medium-sized cleanroom networks at a reasonable cost. The MAC 10 Original Control System is ideal for applications requiring frequent adjustment of air flow rates and can replace manual, phase-control Fan Filter Unit switches. The MAC 10 Original Control System performs status monitoring, speed adjustment and “global set-back” speed adjustment.

The MAC 10 Original Control System’s advantages over competing models include faster setup and calibration time, quieter performance and energy savings through a “global set-back” feature that maintains balanced room set points in rooms used fewer than 24 hours a day.

“The MAC 10 Original Control System is a highly effective way to control
and monitor fan motors,” says Paul Christiansen, Envirco’s Director of Sales.

“The built-in MODBUS communication protocol and analog input, along with easy-to-use software and addressable units, make the MAC 10 Original the ideal solution for any cleanroom environment.”

The MAC 10 Original Control System mounts easily on the wall and requires no installer configuration. It has a simple user interface, and is able to support small networks. The device can be used with a variety of voltage and current models and wire configurations.

Envirco Corporation is a division of Fedders Engineered Products (NYSE: FJC), Liberty Corner, NJ, that manufactures clean air systems for the medical, pharmaceutical and laboratory markets, as well as for other sectors requiring ultra-clean environments for critical technologies.
