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.

Applications

  • Auto body blowoff
  • Package cleaning
  • Part drying after wash
  • Dust removal prior to packaging
  • Scrap removal
  • Filling operations
  • Pre-paint dust removal
  • Wiping contaminants
  • Cooling hot parts
  • Neutralizing static
  • Cleaning molded parts

Advantages

  • Easy electrical hook-up; 100-240VAC, 50/60Hz
  • NEMA 4/IP66 environments
  • Compact sensor for mounting in tight spaces
  • Eight function analog timer for on/off, pulsing and delay control
  • Timer setting from 0.10 sec. to 120 hrs.
  • Sensor withstands water and dust for accurate readings
  • Sensor has superior immunity to noise and inductive loads
  • Sensor has long distance sensing up to 3 feet (1 meter)
