The BelAire QP318VE is a 5 HP, 208–230V single-phase compressor with a two-stage cast iron pump, 80-gallon vertical ASME tank, and 175 PSI maximum pressure. Its main advantage is the sound enclosure, which brings operating noise down to a published 66 dBA while keeping the compressor suitable for home and light commercial environments. BelAire also specifies a 40-amp breaker for the dedicated circuit, giving you a concrete starting point for electrical planning before installation. The compressor includes a magnetic starter, but circuit installation and conductor sizing should still be handled by a qualified electrician.
The two-stage pump compresses air in two steps, with cooling between stages, allowing the QP318VE to reach 175 PSI while managing compression heat. An integrated aftercooler further reduces discharge temperature and helps remove moisture before air reaches the tank. The cast iron cylinder is designed to maintain its bore under repeated heating and cooling, while the belt-driven, splash-lubricated pump includes an oil sight glass for routine checks. Low-oil protection and high-temperature shutdown provide additional safeguards, particularly important because the pump operates inside a high-strength ABS enclosure with a dedicated cooling fan. Keep the enclosure's airflow openings clear during operation.
The QP318VE is a good fit for one- and two-bay repair shops, serious home workshops, and shared or attached buildings where compressor noise matters. Its vertical 80-gallon tank and approximately 38.2" × 24.3" footprint make efficient use of floor space, while the stored air provides reserve capacity for intermittent tools such as impact guns, air ratchets, blow-off equipment, plasma cutters, and occasional spraying. If your panel can support the specified 40-amp circuit but you want to avoid stepping up to a larger motor, this model offers a practical balance of air capacity, noise control, and electrical requirements.

One specification we are leaving blank on purpose. The delivered air volume for this model appears in the product data as a bare number with no unit attached. We will not turn that into a published flow rate when the source data does not establish what the number means — the risk of giving you a wrong CFM figure is greater than the inconvenience of leaving it blank.
If air delivery is what your purchase decision depends on, ask us in writing and we will have BelAire confirm the figure and its units before you order.
Certification, Stated Honestly
This compressor's data records ASME certification, and it applies to the pressure-containing components: the tank is an ASME-certified pressure vessel, and the relief devices are ASME safety valves.
The data does not record any listing by an independent testing laboratory for the electrical assembly as a whole. That is a separate approval from a separate body, and an ASME tank certification does not substitute for it. Insurers, workplace safety programs and local electrical inspectors may require an independent electrical listing for equipment installed in a commercial facility; in a private garage, it may not matter at all. Find out which situation applies to you before you buy, not on inspection day.
Shipping and Delivery
This compressor ships by freight to the lower 48 states at no additional charge. Plan the unload before delivery: you will need a forklift, loading dock, or another suitable way to receive the pallet, or you can arrange to collect it from the freight terminal.
Residential delivery carries an additional fee, which is applied and shown at checkout.
Inspect the crate and equipment before signing for the shipment. If you see damage, note it on the bill of lading while the driver is still present. Signing a clean receipt and reporting damage afterwards leaves you with very little leverage on a freight claim.
Warranty
A 2-Year consumer warranty is recorded for this model, and the warranty document linked on this page is the governing version.
Whatever the warranty covers, protect your position if something fails: photograph the problem where it sits, leave the assembly intact, and contact us before dismantling anything. Taking a component apart before it has been assessed can make it much harder to establish what failed and whether the warranty applies.
