The BelAire 318V is a 5 HP two-stage air compressor with an 80-gallon vertical ASME tank, designed to deliver substantial air capacity without consuming a long stretch of valuable floor space. Its vertical configuration occupies roughly 39" × 24", making it easier to place in a corner than a comparable horizontal receiver. The pump delivers 18.5 CFM at 100 PSI and 16.6 CFM at 175 PSI, while the motor can be configured for 208V or 230V single-phase power. A factory-installed magnetic starter provides motor switching and overload protection. Note: allow approximately 77" of clear height for the compressor, plus additional space for plumbing and service access.
The two-stage belt-driven pump compresses air in two steps, with cooling between stages, allowing the compressor to reach 175 PSI while maintaining strong air delivery at higher pressure. That matters when using tools that need consistent pressure rather than short bursts of airflow. The pump is splash lubricated and includes an oil sight glass for routine level checks, while the fully enclosed high-flow belt guard protects the drive components without restricting cooling airflow. BelAire does not specify a breaker size or amp draw for this model, so electrical protection and conductor sizing should be confirmed with a qualified electrician based on the selected 208V or 230V supply and local requirements. Published pump-construction details also conflict, so confirm the exact material if that specification is important to your purchase.
The 318V is a practical choice for small and mid-size automotive shops, restoration and fabrication spaces, and well-equipped home garages that do not have three-phase service. Its vertical design is especially useful where floor space is limited but adequate ceiling height is available. The 80-gallon receiver provides reserve air for demanding pneumatic tools, while the two-stage pump is suited to regular shop use rather than occasional tire inflation. Buyers planning paint work or other moisture-sensitive applications should also account for appropriate downstream air treatment, as the recommended CPXHT25 dryer is not included.

Certification, Stated Plainly
The receiver is an ASME-certified pressure vessel fitted with a safety valve. This certification applies to the pressure vessel itself, which is rated for 175 PSI.
The available data does not claim a third-party safety listing for the complete packaged machine, so we will not imply one. If your insurer, corporate facility standard or local inspector requires an independent listing for hard-wired shop equipment, ask us to confirm the available documentation with BelAire in writing before ordering.
Shipping & Delivery
Ships palletized by freight to the lower 48 states, with freight included.
Plan unloading before delivery. The carrier delivers to the tailgate, so you will need a forklift, loading dock or pallet jack to move the compressor safely. Terminal pickup is an alternative if you prefer to collect the pallet yourself.
Residential deliveries carry an additional fee.
Inspect before signing. Check the compressor for shipping damage and record any issues on the bill of lading with the driver present. A clean signed receipt can make a freight damage claim difficult.
Warranty
BelAire provides a 2-Year bumper-to-bumper factory warranty for consumer and commercial use, covering the complete unit with no additional purchase required.
If the pump develops a problem, do not disassemble it before opening a warranty claim. Keep the affected components intact so the manufacturer can assess the failure. Contact us first and we will help start the claim.
