BelAire 6312HE4 Air Compressor – 20HP Horizontal

BelAire 6312HE4 Duplex Air Compressor: Industrial 460V 15-HP Power with Fail-Safe Redundancy

The BelAire 6312HE4 is a high-capacity 15-HP duplex air compressor engineered for large-scale industrial facilities that operate on a 460V electrical infrastructure. Featuring two independent 7.5-HP motors and two-stage cast iron pumps, this unit provides critical built-in redundancy on a massive 120-gallon horizontal ASME tank. By sourcing this high-efficiency system through Muldepot.com, your facility is protected against unplanned production downtime; if one pump assembly requires maintenance, the second unit continues to provide air, ensuring your essential pneumatic infrastructure remains operational 24/7.

The core of the 6312HE4’s performance lies in its dual two-stage pumps, delivering a consistent 50.6 CFM at 100 PSI and 46.4 CFM at 175 PSI. As a premier offering in our industrial-scale compressed air solutions, this unit utilizes 460V NEMA-rated high-efficiency motors that lower amperage draw and reduce long-term energy costs. The integrated automatic alternator balances the workload between both pumps, effectively doubling the system’s operational lifespan and preventing heat-induced fatigue. This duplex setup ensures peak pressure stability for heavy-duty manufacturing, multi-bay automotive centers, and automated assembly lines requiring high-volume air flow.

“The BelAire 6312HE4 has been the backbone of our 460V manufacturing plant for over a year. The duplex redundancy saved us twice during routine maintenance windows, allowing our CNC lines to stay active. It delivers a massive volume of air with surprisingly low vibration, and the high-efficiency motors have noticeably stabilized our shop’s electrical load. It’s the ultimate fail-safe for any high-output facility.”

Advanced Durability & Lifecycle Engineering

In the grueling environment of heavy industry, the BelAire 6312HE4 excels by utilizing solid cast-iron cylinder construction to eliminate thermal warping. The two-stage compression process significantly cools the air between stages, preventing moisture-driven corrosion and ensuring tight mechanical tolerances are maintained throughout the operational lifecycle. Furthermore, the 460V configuration provides a more efficient power draw, reducing heat buildup within the NEMA-rated motors. This focus on durability protects your facility against heat-induced performance degradation and maximizes your long-term ROI on pneumatic equipment.

Strategic Industry Use Cases

• Large-scale Manufacturing Plants operating on 460V industrial grids.
• Heavy Metal Fabrication Facilities requiring high-volume air for plasma and CNC.
• Industrial Sandblasting Operations where constant PSI is critical for flow.
• Commercial Automotive Assembly Lines with high-frequency pneumatic tools.
• Fleet Maintenance Hubs requiring fail-safe air for 24/7 logistics support.
