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 photoelectric sensor with a timing control that limits compressed air use by turning off the air control valve when no part is present. The timing control permits easy tuning to the application requirements while providing flexibility in sensing distance. Available to improve applications with flow up to 350 SCFM.
