The BelAire 6312H4 Iron Series is a 10 HP, 460V three-phase compressor built for facilities that already have 460V plant power. Its horizontal 80-gallon ASME tank keeps the overall height to 49 inches, while the two-stage cast iron pump delivers 35 CFM at 100 PSI and 32 CFM at 175 PSI, with 175 PSI maximum pressure. The factory-configured 460V motor and magnetic starter eliminate the need to adapt the compressor to a lower-voltage supply. Note: the source does not provide breaker or amp-draw figures, so a qualified electrician should size the circuit, conductors, and disconnect for the installation.
The pump uses solid cast iron cylinders, automotive-style rod bearings and wrist pins, and splash lubrication with an oil sight glass for routine checks. Two-stage compression divides the work of reaching high pressure between two cylinders, while the integrated aftercooler removes heat from the compressed air before it enters the tank. In practical terms, that combination supports sustained air delivery while helping reduce the amount of heat and moisture carried downstream. A manual tank drain is fitted, so regular condensate removal remains part of routine maintenance. BelAire recommends the CPXHT50 dryer for applications requiring drier air, but it is not included.
At 73" long × 24" wide × 49" high and 830 lbs, the 6312H4 is designed for industrial facilities, large automotive shops, production areas, and other operations with 460V three-phase service. The horizontal configuration works particularly well where ceiling clearance is limited, while the 10 HP pump and 80-gallon receiver provide the capacity for multiple air tools and heavier workloads. Plan the installation around the machine's substantial weight, provide access to the pump for belt and oil service, and have a qualified electrician verify electrical requirements and motor rotation before startup.

| Before you order |
Ask us to put the tank capacity in writing |
Published figures for the tank capacity differ, so both readings are set out above beside the source that states each one. The 80 gallon wording is identical to the line BelAire uses on its 80 gallon models, which makes it look like sheet text that travelled — but a compressor's air reserve is not something to buy on a guess. If the tank capacity decides your purchase, confirm it with us in writing before you commit and we will get it from the manufacturer.
Certification, Stated Plainly
The tank and its safety valve carry an ASME rating, which is a pressure-vessel standard covering the vessel that holds the air. It is not a statement about the machine's electrical assembly, and the product data does not claim a third-party North American electrical safety listing for the machine as a whole.
That distinction matters more on a 460V unit than it does on a small shop machine, because the people most likely to ask for independent electrical certification are often the industrial insurers and plant safety officers responsible for approving higher-voltage equipment. If that describes your site, ask us for the documentation supplied with the unit and get the answer in writing before you order.
Shipping and Delivery
This compressor ships by freight carrier to the lower 48 states on a pallet. You are responsible for getting the 830 lb shipment off the truck, so plan on a loading dock, forklift, or pallet jack with a hard, level approach. If you have none of those options, terminal pickup is usually simpler and may be less expensive; we can help arrange that with you.
Residential delivery carries a residential fee, which will be quoted with your shipping at checkout.
Inspect the equipment before you sign for it. Check the tank, motor terminal box, gauge and guard, and note anything that looks damaged or out of place on the delivery paperwork while the driver is still there. Once you have signed a clean receipt, a freight claim becomes much harder to establish.
Warranty
The listed coverage is a 2-Year factory warranty for both consumer and commercial use, with no additional purchase required.
Treat the warranty document supplied with the machine as the final authority and read it when the compressor arrives, not when something goes wrong. One important house rule: do not open the pump, motor or starter enclosure before a warranty claim has been raised. A component that has been dismantled before inspection is much harder to assess, and that can complicate a claim that might otherwise have been straightforward.
