EXAIR’s EFC is designed to minimize compressed-air use on blowoff, drying, cooling, conveying, and static-elimination operations. The controller 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 of the controller permits tuning to the application requirements with numerous valve operating modes and timing delays. The compact photoelectric sensor has a sensitivity adjustment and detects objects up to three feet away. The sensor is resistant to noise and inductive loads that are common to industrial environments and installs in tight spaces with the supplied mounting bracket. The electrical connection supports voltages from 100V to 240VAC (50/60 Hz). A NEMA 4 polycarbonate enclosure allows the unit to support applications in wet locations. The timing control unit and photoelectric sensor are equipped with a 9’ (2.74m) power cord. Three models of the EFC are offered that include the timing control, photoelectric sensor, and choice of a 40, 100 or 200 SCFM solenoid valve.
