BelAire 6312D 20HP 120-Gallon Duplex Air Compressor for Heavy-Duty Industrial Redundancy
The BelAire 6312D Air Compressor is the high-capacity solution for industrial facilities that require maximum air volume without sacrificing system reliability. By integrating two 10HP heavy-duty pumps on a single 120-gallon horizontal tank, this duplex system provides reliable redundant power for critical manufacturing and automotive operations. Professional shop owners trust the Iron Series to maintain uninterrupted production workflows even during peak demand cycles or scheduled motor maintenance. Choosing this model from BelAire industrial compressors ensures that your facility has a consistent air reserve capable of delivering an impressive 70 CFM at 100 PSI.
The BelAire 6312D Air Compressor features two 10HP motors and solid cast iron pumps that deliver a combined 64 CFM at 175 PSI for maximum high-pressure output. This twin-motor setup optimizes pump cooling cycles by alternating lead/lag operation via an intelligent control panel, which effectively doubles the service life of internal components. For managers sourcing BelAire duplex systems, the mounted and pre-wired magnetic starters offer superior motor protection and simplified electrical integration for 20HP loads. The duplex design excels at reducing thermal stress, ensuring that moisture levels remain low and pneumatic tool efficiency remains high during continuous sandblasting or industrial painting.

It’s a heavy unit at nearly 1,400 lbs, so make sure your floor is ready for a serious industrial asset.
Redundant Duplex Engineering and Internal Build
- Having a twin pump configuration ensures your shop stays fully operational even if one motor requires scheduled maintenance
- Mechanical friction and noise are suppressed significantly by slow-speed pumps while extending the overall valve life
- Every unit is built with automotive-style rod bearings and wrist pins for long-term reliability under load
- The use of concentric ring valves is specifically designed to provide high airflow while resisting carbon buildup
- Operational safety is guaranteed as each ASME certified tank meets the most stringent industrial standards
Ideal Applications for Continuous Air Operations
- Perfectly suited for large-scale manufacturing plants running multiple CNC machines and automated lines
- This system is a staple for commercial sandblasting facilities requiring non-stop abrasive cleaning power
- Guarantees a stable and consistent air supply for high-volume automotive shops with multiple spray booths
- A smart choice for heavy equipment repair facilities utilizing 1-inch and larger impact wrenches
- Delivers the sustained volume required for industrial packaging and bottling plants using pneumatic actuators
