BelAire 6312D4 2 x 10HP 120G H Iron Series Elec Duplex Air Compressor
BelAire 6312D4 2 x 10HP 120H Gallon Iron Series Three Phase Electric Duplex Air Compressor
⚠ IMPORTANT: Three-Phase Power Required
This compressor MUST have three-phase electric power (460V / 3-Phase). Verify your facility has the proper electrical service before ordering.
The BelAire 6312D4 represents the pinnacle of industrial air compression technology, delivering 70 CFM @ 100 PSI (64 CFM @ 175 PSI) from its robust dual 10HP motor configuration. This complete duplex air compressor system comes equipped with everything you need to optimize your work and minimize downtime in the most demanding shop environments. Featuring two independent pumps and motors with an intelligent alternator system, the 6312D4 ensures optimal performance, extended pump life, and continuous air delivery even during peak demand.
Built on BelAire's legendary Iron Series platform, this duplex compressor features all cast iron construction throughout its pump assemblies—engineered for decades of reliable service in professional automotive shops, manufacturing facilities, and industrial operations. The 120-gallon horizontal ASME-certified tank provides substantial air storage capacity to handle multiple high-demand tools simultaneously, while the included magnetic starter ensures safe, reliable motor protection and control.
Why Choose the BelAire 6312D4 Duplex System?
Duplex air compressor systems deliver distinct advantages over single-pump configurations. The BelAire 6312D4 alternates operation between its two pumps, dramatically reducing wear on each individual pump and extending overall system lifespan. Should one pump require service, your operation continues with the second pump—eliminating costly downtime. The alternator control system intelligently manages pump cycling to ensure balanced runtime and optimal efficiency across both compressor units.
Every Iron Series compressor is backed by BelAire's comprehensive 2 Year Bumper to Bumper Warranty with no additional purchase required—a testament to the quality and durability built into every component. Each unit is 100% factory tested at full pressure before leaving the facility, ensuring it arrives ready to perform from day one.

Cast Iron Construction Advantage
The BelAire Iron Series utilizes solid cast iron pumps throughout—the gold standard for industrial air compressor construction. Cast iron delivers exceptional thermal management, dissipating heat far more effectively than aluminum alternatives. This translates to cooler operating temperatures, reduced wear, minimal oil breakdown, and significantly extended pump life. For shops running extended hours or operating in hot environments, cast iron construction is not just preferred—it's essential for long-term reliability.
