BelAire 3312D 2 x 5HP 120G 2-Stage H Elec Duplex Air Compressor
BelAire 3312D 2 x 5 HP 120H Gal. Horizontal Two Stage Three Phase Electric Duplex Air Compressor
⚠ CRITICAL REQUIREMENT: This compressor MUST have three-phase electric power (208-230V / 3-Phase). Verify your facility has the proper electrical service before ordering.
The BelAire 3312D is a professional-grade duplex air compressor engineered to deliver maximum uptime and reliability for demanding commercial and industrial applications. This powerhouse features dual 5 HP motors mounted on a robust 120-gallon horizontal tank, providing 37 CFM at 100 PSI and capable of reaching pressures up to 175 PSI. Built with solid cast iron cylinders and two-stage compression, the 3312D ensures consistent performance even under heavy, continuous use.
What sets this duplex system apart is its intelligent alternator control that automatically rotates operation between the two pumps and motors. This advanced feature dramatically reduces wear on individual components, extends service intervals, and virtually eliminates downtime due to pump failure. When one pump is running, the other stands ready—giving you the redundancy and peace of mind that your air supply will never let you down during critical operations. The dual pressure switch control and magnetic starters ensure seamless, automatic operation tailored to your facility's air demand.
This compressor arrives 100% factory tested at full pressure and comes complete with everything you need to optimize your compressed air system right out of the crate. The tri-voltage motors provide installation flexibility, while ASME-certified tank and safety valves guarantee compliance with the strictest industry standards. Backed by a comprehensive 2-year bumper-to-bumper warranty (including valves), the BelAire 3312D represents a serious investment in reliability, performance, and long-term cost savings for shops that demand professional-grade air delivery.
