Six Steps to Optimizing Your Compressed Air System

Electronic Flow Control (EFC)

Electronic Flow Control

EXAIR's EFC is a user-friendly electronic flow control 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 application requirements while providing flexibility in sensing distance.

For most companies, the air compressor uses more electricity than any other type of equipment. 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 the part is present and provides just enough air to complete a specific task or operation.
