Electronic flow controller Model 9055 EFC™

volumetricfor airfor compressed air

Overview
EXAIR's EFC is a user-friendly electronic flow control for compressed air designed to minimize compressed air consumption on blowoff, drying, cooling, conveying and static elimination tasks. The unit combines a photoelectric sensor with an adjustable timing controller that shuts the solenoid valve when no part is detected. The timer allows fine tuning to application requirements while the sensor provides flexible sensing distance. Available for applications up to 350 SCFM (9,911 SLPM).

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

• Simple electrical hook-up: 100–240 VAC, 50/60 Hz
• NEMA 4 / IP66 enclosure for wet or dusty environments
• Compact sensor for installation in confined spaces
• Eight-function analog timer supporting on/off, pulsing and delay modes
• Timer range from 0.10 second to 120 hours
• Sensor designed to withstand water and dust for reliable detection
• High immunity to electrical noise and inductive loads
