BelAire 438VL Iron Series 7.5 HP 80-Gallon Two-Stage Compressor — 3-PhaseThe 438VL is the dual-voltage member of BelAire’s 7.5 HP Iron Series: one machine that wires into either a 208 Volt or a 230 Volt 3-phase supply without a different part number, a different motor or a special order. If you have ever had a compressor delivered and then discovered the building’s three-phase service was the other one, you already know why that matters more than any headline figure.Underneath the wiring flexibility it is a solid cast iron two-stage pump with automotive-style rod bearings and wrist pins, on a vertical 80 gallon ASME tank, with a magnetic starter fitted. BelAire sizes the larger CPXHT50 dryer to this model rather than the smaller unit it recommends across most of the range — a detail that tells you how much air it expects this compressor to be moving.Dual-voltage three-phase, and why it is a buying featureThree-phase service in North American buildings comes at more than one voltage, and shops rarely get to choose which one they inherited. A compressor built for one and not the other becomes an expensive problem the moment the electrician opens the panel. The 438VL is built to be wired into either, so the decision moves from “hope it is the right one” to a straightforward connection.It also protects the machine’s second life. Shops move. A dual-voltage unit goes with you to a building whose service is not the same as the one you are leaving, which is not true of a single-voltage machine.What BelAire does not publish for this model is a breaker size — the recommendation reads “consult a certified electrician”, which at 7.5 HP three-phase is the right answer, because the correct breaker and conductor sizing depend on which of the two supply voltages you are on and on the length of the run. Book the electrician before the machine arrives.An honest note on this model’s published airflow, and on its voltage fieldTwo of BelAire’s numbers for the 438VL do not agree with each other, so we are printing both rather than choosing.Airflow at 100 PSI. The feature list and the specification block say 23 CFM. The product description says approximately 22 CFM. The 19 CFM figure at 175 PSI is consistent across the sources we hold; the 100 PSI figure is not. Ask us to confirm in writing before you order if that difference is load-bearing for your air system design.Supply voltage. The title, the feature list and the specification block all describe a 208 Volt / 230 Volt three-phase machine. One stray field on the same listing reads 460 volt. Three sources against one is suggestive, not conclusive, and wiring a compressor to the wrong service is not a mistake you get to make twice — so confirm your supply with us in writing before you buy, and we will have BelAire verify the build.Will it fit?Vertical tank, so height is the constraint: 72" to the top of the machine, plus clearance for the outlet plumbing and access to the pressure switch. Footprint is about 37" by 24". Do not box it into a corner — the belt guard, the oil sight glass and the manual tank drain all need to be reachable during normal weekly maintenance.The floor needs to be level and solid, and it is carrying roughly 600 lbs on a small pad. Getting it from the pallet to that spot is the customer’s job and is worth planning before delivery day, not on it.The pump and the tankTwo-stage means the air is compressed twice, with the second cylinder finishing what the first started. That is what lets the machine hold 175 PSI usefully rather than merely reaching it, and it is why two-stage pumps run cooler and last longer at high pressure than a single-stage pump pushed to the same figure.The pump is solid cast iron throughout and belt driven, with splash lubrication and an oil sight glass. Automotive-style rod bearings and wrist pins mean the reciprocating assembly is built the way an engine bottom end is built rather than as a consumable. The fully enclosed belt guard covers the drive without choking the cooling airflow the flywheel provides.The receiver is an 80 gallon vertical ASME tank with a safety relief valve and a 3/4" outlet, drained manually. Drain it at the end of the working day; standing water is what kills receivers.Perfect For Shops on three-phase service that do not yet know which voltage — the dual-voltage build removes the question. Busy multi-bay workshops where more than one air tool is in use at once. Operations that expect to relocate and want the compressor to be usable in the next building. Fleet, agricultural and industrial maintenance with continuous rather than intermittent air demand. What’s in the BoxCompressor complete: solid cast iron two-stage pump, motor, vertical ASME tank, magnetic starter, start-stop pressure switch, pressure gauge, fully enclosed belt guard, oil sight glass, manual tank drain, safety relief valve.Not included: the CPXHT50 dryer BelAire recommends alongside it, plus any filtration, regulation or shop plumbing.SpecificationsMotor and electrical supply Rated power 7.5 HP Supply 208 Volt or 230 Volt AC, 3-phase (wireable for either) — see the voltage note above; one field on this listing reads 460 volt and contradicts the other three sources Magnetic starter Included Breaker Not published — consult a certified electrician Pump and output Pump type Two-stage, solid cast iron, belt drive, splash lubricated Bearings Automotive-style rod bearings and wrist pins Delivered air at 100 PSI Disputed. 23 CFM per the feature list and specification block; approximately 22 CFM per the product description.

That is what the product data claims, and on a receiver holding 175 PSI it is the claim that carries the most weight.The data claims no third-party safety listing for the packaged machine. There is no electrical listing mark stated anywhere in the material we hold, and we are not going to invent one for the sake of a tidier page. If your insurer, your facility standard or your local inspector requires a specific listing on hard-wired shop equipment, raise it with us before you order.We would rather tell you that plainly than let a badge you assumed was there turn up missing during an inspection.Getting it to youThe compressor travels palletised as freight to the lower 48 states, free of charge.Two customer responsibilities are worth knowing in advance. Unloading is yours: the driver delivers to the tailgate, not into the building, so have a forklift, a dock or a pallet jack ready — or select terminal pickup and collect the pallet from the freight terminal instead. And if the address is a home rather than a commercial premises, it is a residential delivery and carries a residential fee.Finally, inspect before you sign. Note every mark on the bill of lading while the driver is still there. A signature with no exceptions written on it closes off the claim.WarrantyCovered by BelAire’s 2 Year bumper-to-bumper factory warranty, consumer and commercial, on the complete unit and with nothing extra to buy.And the rule that protects the claim: leave the pump assembled. If it develops a fault, call us before a spanner goes near it — a stripped pump cannot be assessed, and a claim on one rarely ends well.
