Blowoff, Drying, Cooling, & Conveying Apps

EXAIR’sEFC is designed to minimize compressed-air use on blowoff, drying,cooling, conveying, and static-elimination operations. The controllercombines a photoelectric sensor with a timing control that limitscompressed-air use by turning it off when no part is present. Thetiming control of the controller permits tuning to the applicationrequirements with numerous valve operating modes and timing delays. Thecompact photoelectric sensor has a sensitivity adjustment and detectsobjects up to three feet away. The sensor is resistant to noise andinductive loads that are common to industrial environments and installsin tight spaces with the supplied mounting bracket. The electricalconnection supports voltages from 100V to 240VAC (50/60 Hz). A NEMA 4polycarbonate enclosure allows the unit to support applications in wetlocations. The timing control unit and photoelectric sensor areequipped with a 9’ (2.74m) power cord. Three models of the EFC areoffered that include the timing control, photoelectric sensor, andchoice of a 40, 100 or 200 SCFM solenoid valve.
