 EFC? Electronic Flow Control for Compressed Air

Electronic Flow ControlMinimize 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?
EXAIRs 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.
