EFC™ Electronic Flow Control for Compressed Air


Minimize compressed air use
for blowoff, drying, cooling, conveying and static elimination operations!

Dramatically reduces compressed air costs by turning off the compressed air when no part is present!

What is the EFC? EXAIR’s EFC™ is a user-friendly electronic flow control for compressed air that is designed to minimize compressed air use on blow off, drying, cooling, conveying and static elimination operations. The EFC combines a photo electric 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.

Why the EFC? 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 those electricity dollars per year if not properly controlled. The EFC has been designed to improve efficiency by minimizing compressed air use and, as a result, reduces compressed air costs. It turns on the air only when a part is present and provides just enough air to complete a specific task or operation.

Photoelectric sensor withstands water and dust.

Applications	Advantages
Auto body blowoff Package cleaning Part drying after wash Dust removal Scrap removal Filling operations Pre-paint dust removal Wiping contaminants Cooling hot parts Neutralizing static Cleaning molded parts	Easy electrical hook-up; 100V-240VAC NEMA 4/IP56 environments Compact sensor for mounting in tight spaces Eight function analog timer for on/off, pulsing and delay control Time setting from 0.10 sec. to 120 hrs. Sensor withstands water and dust for accurate readings Sensor has superior immunity to noise and inductive loads Sensor has long distance sensing up to 3 feet (1m)

The EFC has an easy electrical connection for voltages from 100V to 240VAC, making it suitable for applications throughout the world. The compact photoelectric sensor has a sensitivity adjustment and detects objects up to 3’ (1m) 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.
