BelAire 3312DL4 2 x 7.5HP 120G H 2-Stage Elec Duplex Air Compressor
BelAire 3312DL4 2 x 7.5HP 120 Gallon Horizontal Two-Stage Three Phase Electric Duplex Air Compressor
Maximize uptime and optimize your compressed air system with the BelAire 3312DL4 duplex air compressor. Engineered for demanding professional environments, this two-stage, dual-motor compressor delivers 50.50 CFM at 100 psi from a robust 120-gallon horizontal tank. Featuring two 7.5 HP motors working in tandem with an intelligent alternator system, this unit ensures continuous air supply while reducing wear and extending equipment life. Built with solid cast iron cylinders, tri-voltage 460V 3-phase motors, and magnetic starters, the 3312DL4 is factory-tested to full pressure and backed by a comprehensive 2-year bumper-to-bumper warranty.
Professional Duplex Power for Maximum Reliability
The BelAire 3312DL4 is purpose-built for shops and facilities that cannot afford compressed air interruptions. This compressor comes complete with everything you need to optimize your work and minimize downtime. The BelAire duplex compressors are available up to 20 HP and can deliver up to 50.50 ACFM on three-phase power. Unlike single-motor units, this duplex configuration employs two independent pumps and motors working alongside an advanced alternator system that intelligently rotates operation between the two compressors. This design ensures optimal performance, balanced run times, and the peace of mind that comes from built-in redundancy.
When one compressor handles the demand, the second remains on standby, ready to kick in when air consumption increases. This not only extends the service life of both units but also provides a fail-safe: should one compressor require service, the other continues to supply air to keep your operations running. All BelAire two-stage compressors come with a full 2-year warranty, including coverage for valves—a testament to the durability and engineering quality behind every unit.
Key Highlights
- Dual 7.5 HP Motors: Two independent compressors with alternator control for balanced operation and built-in redundancy
- Two-Stage Cast Iron Construction: Solid cast iron cylinders deliver efficient compression and long-lasting durability
- Generous 120-Gallon Horizontal Tank: ASME-certified tank with 175 psi max pressure provides ample reserve capacity
- Industrial 460V 3-Phase Power: Tri-voltage magnetic starter motors designed for heavy-duty, continuous-use environments
- 100% Factory Tested & 2-Year Warranty: Each unit is tested at full pressure before shipment and backed by comprehensive bumper-to-bumper coverage
⚠ IMPORTANT: Three-Phase Electric Power Required
This compressor MUST be connected to 460V three-phase electrical service. Verify your facility's electrical capacity before ordering. Single-phase power is not compatible with this model.
Engineered for Continuous Performance
The BelAire 3312DL4 combines time-tested two-stage compressor engineering with the intelligent redundancy of a duplex system. The dual pressure switch control manages both compressors, ensuring optimal cycling and preventing overwork of either motor. Magnetic starters provide reliable, safe motor engagement every time, while the ASME-certified horizontal tank and safety valves meet or exceed all industry standards.
With dimensions of 77" L x 27" W x 56" H and a shipping weight of 886 lbs, this is a substantial, floor-mounted unit designed for permanent installation in professional shops, manufacturing facilities, automotive service centers, and industrial applications. The horizontal tank configuration keeps the footprint manageable while maximizing air storage capacity.
