BelAire 4312DL4 Air Compressor – 15 HP Duplex Industrial Two-Stage Air Compressor

The BelAire 4312DL4 Air Compressor is a heavy-duty industrial duplex piston air compressor designed for manufacturing plants, automotive production facilities, CNC machining centers, and large workshops that require continuous, high-volume compressed air. Built with two 7.5 HP electric motors (15 HP total), rugged cast iron two-stage pumps, and a large 120-gallon horizontal ASME-certified tank, this system is engineered for reliability, efficiency, and long service life.

It delivers approximately 46 CFM at 100 PSI and operates up to 175 PSI maximum pressure, making it suitable for multi-user air systems and demanding industrial applications.

Key Features

- Duplex configuration: 2 × 7.5 HP motors (15 HP total)
- Heavy-duty two-stage cast iron pump system
- Large 120-gallon horizontal ASME air tank
- High output: ~46 CFM at 100 PSI
- Maximum pressure: 175 PSI
- Magnetic starters included for motor protection
- Alternator system for balanced runtime between pumps
- Built-in redundancy (one pump can operate independently)
- Low-RPM industrial design for durability and reduced wear
- Designed for continuous-duty industrial operation

Industrial Performance

The BelAire 4312DL4 is built for environments where air demand is constant and downtime is costly. Its duplex system allows alternating operation between compressors, reducing wear and improving overall efficiency. When demand increases, both compressors engage to maintain stable pressure across multiple production lines.

The cast iron pump design ensures thermal stability and long service life, even under continuous heavy-duty cycles.

Ideal Applications

- Manufacturing plants
- CNC machining facilities
- Automotive production lines
- Metal fabrication workshops
- Industrial maintenance systems
- Packaging and assembly operations
- Multi-user compressed air networks
