BelAire 6320D Air Compressor – 20HP Duplex

Description

BelAire 6320D Air Compressor – 20 HP Duplex Industrial Two-Stage Air Compressor

The BelAire 6320D Air Compressor is a heavy-duty industrial duplex piston compressor designed for manufacturing plants, CNC machining centers, automotive production facilities, and large-scale workshops requiring continuous, high-volume compressed air. Built with two 10 HP electric motors (20 HP total), rugged two-stage cast iron pump systems, and a large 200-gallon ASME-certified horizontal tank, this unit delivers exceptional airflow, redundancy, and long-term reliability for demanding industrial environments.

It produces up to 70 CFM at 100 PSI and operates at a maximum pressure of 175 PSI, making it suitable for multi-user air systems and continuous production operations.

Key Features

• Duplex configuration with 2 × 10 HP motors (20 HP total)
• Heavy-duty two-stage cast iron pump system
• Large 200-gallon horizontal ASME air receiver tank
• High airflow output: ~70 CFM at 100 PSI
• Maximum pressure: 175 PSI
• Magnetic starters included for motor protection
• Alternator system balances runtime between compressors
• Built-in redundancy for uninterrupted operation
• Designed for 3-phase industrial electrical systems
• Fully enclosed belt guard for safety and durability
• Continuous-duty industrial design for 24/7 environments

Industrial Performance

The BelAire 6320D is engineered for continuous air demand environments where downtime is not acceptable. Its duplex system allows one compressor to handle lighter loads while both units engage during peak demand, improving efficiency and reducing wear.

The 200-gallon tank stabilizes pressure across multiple workstations, making it ideal for facilities running several pneumatic tools or production lines simultaneously.

Ideal Applications

• Manufacturing plants
• CNC machining operations
• Automotive production facilities
• Heavy fabrication workshops
• Industrial maintenance departments
• Packaging and assembly lines
• Multi-user compressed air systems

Before ordering the BelAire 6320D Air Compressor – 20HP Duplex from BelAire, review the points below against your actual site conditions and workload. Published specifications describe the equipment under test conditions, and real-world performance depends on how closely your application matches those conditions. Buyers in the United States, Canada, and Asia should also confirm local voltage and frequency requirements, applicable safety or emissions standards, and freight or import logistics for the destination before finalizing an order.

What to Check Before You Buy

• Total the real CFM demand of every tool that could run at the same time, then add reserve capacity for leaks and future tools – not just the single largest tool's rating.
• Confirm voltage and phase availability (120V/240V, single/three-phase) matches the compressor's electrical requirement.
• Check tank size relative to duty cycle – a larger tank reduces motor cycling on intermittent loads but does not substitute for adequate CFM on continuous-demand tools.
• Review noise rating if the compressor will run in an occupied or noise-sensitive space.

Does tank size matter more than CFM for a shop air compressor?

CFM output matters more for continuous-demand tools (sanders, grinders); tank size matters more for intermittent high-draw tools (impact wrenches, nail guns) where the tank supplies a burst faster than the motor could alone. Undersized CFM cannot be fixed by a bigger tank if the tool's continuous demand exceeds the compressor's output.

For sizing help across the full Compressor category, compare specifications side by side before committing to a specific model, and confirm current pricing, availability, and freight details for your location. Keep the supplier data sheet and any acceptance criteria on record for future maintenance and replacement decisions.
