The BelAire QP338VE is a 5 HP, two-stage piston compressor built around one practical advantage: 66 dBA operation. Its solid cast-iron pump sits inside a high-strength ABS sound enclosure with a high-flow cooling fan, reducing the noise that normally makes a compressor disruptive in a working space. It combines an 80-gallon vertical ASME tank, 175 PSI maximum working pressure, and 208-230V 3-phase power, with a magnetic starter already fitted. The enclosure is not simply a sound barrier; it is designed to manage airflow around the pump while keeping the machine substantially quieter.
The cooling system is what makes the enclosed design practical. The high-flow fan moves air through the enclosure and across the pump, helping control operating temperature rather than trapping heat around the compressor. The two-stage pump compresses air in two steps with cooling between stages, while the integrated aftercooler lowers the temperature before air enters the tank. That combination helps reduce moisture reaching downstream equipment and limits heat-related stress on the pump. The cast-iron, splash-lubricated pump also uses an oil sight glass for quick level checks, while low-oil protection and high-temperature shutdown help prevent damage when operating conditions become unfavorable. The pump delivers 18.5 CFM at 100 PSI.
The QP338VE is particularly well suited to professional automotive and body shops, fabrication areas, dealerships, and other workspaces where the compressor needs to operate near people rather than in a separate room. Its vertical 80-gallon configuration also makes efficient use of floor space, while the sound enclosure can be valuable in shops where conversations, phone calls, training, or customer-facing work happen alongside compressed-air operations. For facilities with 208-230V 3-phase service that need substantial air capacity without making the compressor the loudest machine in the room, the Quiet Performance design addresses a very specific problem without moving away from conventional two-stage cast-iron compressor construction.

Certification, Stated Plainly
The tank and safety valves are ASME-rated, and the unit is factory tested at full pressure. This standard applies to the pressure vessel—the tank holding compressed air—not the electrical side of the machine.
BelAire’s published data for this model does not list a third-party North American electrical safety listing, and we will not imply one. If your insurer, corporate safety policy or local inspector requires that type of listing for shop equipment, ask us to confirm the available documentation in writing before ordering.
Shipping & Delivery
Ships by freight to the lower 48 states on a pallet. You are responsible for unloading, so plan for a forklift, loading dock or pallet jack with a flat, level approach. If none is available, terminal pickup may be the better option, and we can arrange it. Residential deliveries carry an additional fee, quoted with shipping at checkout.
Inspect before signing. Check the pallet, enclosure panels, gauge and tank for dents or other damage. Record anything you find on the delivery receipt while the driver is present and take photographs. A clean signed receipt can make a freight damage claim difficult to pursue.
Warranty
BelAire provides a 2-Year factory warranty for this model. The warranty document supplied with the unit controls the coverage, so review it when the compressor arrives.
If a problem develops, do not disassemble the pump, motor or electrical enclosure before opening a claim. Keep the affected components intact for inspection. Contact us first, describe the symptoms and let us start the warranty process.
