What Is The Electronic Flow Control?

EXAIR’s EFC is a user-friendly electronic flow control for compressed air that is designed to minimise compressed air use on blowoff, drying, cooling, conveying and static elimination operations. The EFC combines a photoelectric sensor with a timing control that limits compressed air use by turning it off when no part is present. The timing control permits easy tuning to the application requirements while providing flexibility in sensing distance. The EFC also has eight programmable on and off modes.

For most companies, the air compressor uses more electricity than any other type of equipment. One simple operation that uses compressed air can easily waste thousands of electricity dollars per year if not properly controlled. The EFC has been designed to improve efficiency by minimising compressed air use and, as a result, reduces compressed air costs. It turns on the air only when the part is present and provides just enough air to complete a specific task or operation.

The EFC has an easy electrical connection for voltages from 100 to 240VAC, 50/60 Hz making it suitable for applications throughout the world. The compact photoelectric sensor has a sensitivity adjustment and detects objects up to 1m (3-foot) away. The sensor has superior immunity to noise and inductive loads that are common to industrial environments and installs easily in tight spaces with the supplied mounting bracket. The control system provides flexibility with numerous valve operating modes and timing delays. The polycarbonate enclosure is suitable for use in a wide range of applications including those located in wet environments.

The timing control unit and the photoelectric sensor are equipped with a 2.74m (9-foot) power cord. The timing control unit is housed in a polycarbonate NEMA 4 / IP66 water tight enclosure.

There are four models of the EFC. Each includes the timing control unit and photoelectric sensor with a choice of solenoid valve sizes of 40, 100, 200 and 350 SCFM (1,133, 2,832, 5,664 and 9,911 SLPM).
