Overview
The SMC AC30-E3K01A is a precision air pressure regulator built for reliable pneumatic system control in industrial applications. Part of SMC’s renowned AC30 series, this unit combines modular construction with proven regulator technology for consistent pressure management across manufacturing, automation, and process control installations.
Key Features
- Modular Design: The modular design allows for easy installation and maintenance.
- Reduced Pressure Drop: The pressure drop across the regulator has been reduced, creating a more efficient unit.
- Compact Size: Space-efficient form factor for panel and inline mounting applications.
- Locking Adjustment Knob: The locking adjustment knob prevents accidental setting changes.
- Multiple Configuration Options: Options include a mounting bracket and set nuts for panel mounting as well as pressure gauges.
Technical Specifications
- Maximum Set Pressure: The -A version has a max set pressure of 100 PSI and the -B version has a max set pressure of 125 PSI.
- Port Thread Size: 3/8″ NPT (standard)
- Operating Pressure Range: 0–100 PSI (standard configuration)
- Series: AC30 modular air preparation equipment
- Body Material: Aluminum die-cast with polyacetal components
