The BelAire 418V Iron Series delivers 18 CFM at 100 PSI and 16 CFM at 175 PSI from a solid cast-iron, two-stage pump running at just 689 RPM. That slow pump speed is the key differentiator: fewer operating cycles, lower heat generation and reduced mechanical stress compared with faster-running compressors of the same horsepower. The unit uses an 80-gallon vertical ASME tank and weighs 580 lbs. It operates on 208V or 230V single-phase power with a factory-installed magnetic starter. Note: the compressor stands approximately 72" tall on a 37" × 24" footprint, so verify ceiling clearance, access and floor conditions before installation.
The pump’s low operating speed is paired with automotive-style rod bearings and wrist pins, giving the reciprocating assembly a serviceable design rather than relying on lighter-duty components. Belt drive keeps pump speed below motor speed, while splash lubrication and an oil sight glass make routine oil checks straightforward. The fully enclosed belt guard protects the drive system, and the two-stage design compresses air in two steps with cooling between them before reaching 175 PSI. In practical terms, the combination of high output and slow pump speed is suited to sustained shop use where heat, noise and long-term wear matter as much as raw horsepower.
This compressor is a strong fit for automotive repair shops, restoration garages, fabrication workspaces and other facilities with sustained daily air demand but only single-phase electrical service. Its slow-running cast-iron pump also makes sense for owners who prioritize long service life and lower operating noise over a smaller, lighter machine. The manufacturer does not specify a fixed breaker or amp draw, so have a certified electrician determine the electrical requirements based on your installation and local code. The tank uses a manual drain, and an air dryer, filtration and regulation equipment are not included. BelAire recommends the CPXHT25 dryer for applications where moisture control is important.

Certification, Stated Plainly
The tank is ASME certified and includes a safety relief valve. This certification applies to the pressure vessel, not the complete assembled machine.
This listing does not claim a third-party safety listing for the finished machine. If your insurer, corporate standard or local inspector requires an independently listed assembly for hard-wired equipment, confirm the requirement with us before ordering. We will verify the available documentation with BelAire in writing.
Freight & Receiving
Ships by palletized freight throughout the lower 48 states, with freight included.
Delivery is to the back of the trailer, so plan for a forklift, loading dock or pallet jack with level ground. If unloading equipment is unavailable, terminal pickup is an alternative. Residential deliveries carry an additional fee.
Inspect before signing. Check the tank, shroud, belt guard and gauges with the driver present. Record any damage on the bill of lading and photograph it before accepting the shipment.
Warranty
BelAire provides a 2-Year bumper-to-bumper factory warranty for consumer and commercial use, with no additional purchase required.
If a problem develops, do not disassemble the pump before opening a warranty claim. Keep the compressor intact so the manufacturer can assess the failure. Contact us first and we will help start the claim.
