The BelAire 338VL combines a 7.5 HP three-phase motor with an 80-gallon vertical ASME tank, a solid cast iron two-stage pump, stainless steel valves, and a triple-pass aftercooler. Its 175 PSI maximum gives the receiver substantial pressure reserve, while the vertical layout keeps the footprint to a listed 39" × 24". BelAire also states that every tank is factory tested at full pressure before shipment, rather than testing only a sample. Note: published airflow information conflicts, with 22.3 CFM listed at both 100 PSI and 175 PSI in different sections. Confirm the correct delivered-air rating before using it to size the compressor for a specific continuous-demand tool.
The two-stage pump and triple-pass aftercooler are the key working features. Compressing air in two stages allows the compressor to reach 175 PSI, while the aftercooler helps reduce the temperature of compressed air before it reaches the receiver. The solid cast iron pump adds mass for vibration control and thermal stability, while stainless steel valves are designed for the repeated heat and cycling inside a reciprocating compressor. An oil sight glass makes routine level checks straightforward, and the factory-installed magnetic starter provides motor overload protection from startup.
This compressor is suited to professional repair shops, fabrication areas, and production environments with 208–230V three-phase service and enough vertical clearance for a 73-inch-tall machine. The 80-gallon receiver is useful for applications with intermittent demand because stored air can handle short bursts without immediately starting the motor. The published electrical specification calls for a 40-amp breaker, but the actual circuit should be verified by a qualified electrician. Allow additional clearance for piping and access above the tank, and confirm the listed dimensions before delivery if the installation space is tight.

Certification, Stated Plainly
The receiver is an ASME-certified pressure vessel, and BelAire states that every unit is factory tested at full pressure. These claims apply to the tank.
We do not have a North American third-party electrical safety listing from an accredited testing laboratory for this compressor. Pressure-vessel certification does not cover the motor, starter or control wiring.
If your insurer, facility policy or local electrical inspector requires an independent electrical listing, confirm the requirement with us in writing before ordering. We would rather verify it now than leave you with an inspection issue later.
Delivery
Ships free within the lower 48 states.
Plan unloading before delivery. You will need a forklift or loading dock, or you can choose terminal pickup. Residential delivery is available for an additional fee.
Because the compressor ships upright, inspect the crate for shifting or tipping, along with tank dents, guard damage and any oil on the trailer deck. Record damage on the delivery paperwork and take photographs before the driver leaves.
Warranty
A 2-Year factory warranty applies. Record the serial number when you uncrate the compressor and keep it with your invoice.
If a problem develops, do not disassemble the pump, motor or pressure switch before opening a warranty claim. Contact us first so the manufacturer can inspect the affected component intact.
Follow the recommended oil-change schedule, recheck belt tension after initial operation and drain the receiver regularly.
