GoAir Mini Portable Air Compressor — 110V, Oil-Free, Lift-Lock DutyBuy this one for what it is, and it is excellent: a small, quiet, oil-free air source whose real job is to operate the pneumatic safety locks on a vehicle lift, top up a tyre, and blow out a bearing race. It holds 0.5 Gallon. That is the whole specification argument, and it is the reason the GoAir Mini exists — a shop with a four-post lift and no plumbed air line needs a few seconds of pressure at the lock cylinder, not a compressor room.Judged as a tool-running compressor it will disappoint anyone, and we would rather say so on this page than take the order and hear about it later. Judged as a lift accessory, a tyre inflator and a bench-side utility, it does something a full-size machine cannot: it runs at roughly 55 dBA, needs no oil changes, and is small enough to bolt to the lift post it serves.Will It Fit?The unit measures 10.5" x 16" x 7" (267 mm x 406 mm x 178 mm). It runs on standard 110V power — a normal wall receptacle, no dedicated installation — and the supplied cord is 42" (1,067 mm) long, which is short by design and is the number to check first. Forty-two inches reaches an outlet on the same post or the same wall; it does not reach across a bay. Plan the mounting point around the outlet, or plan the outlet around the mounting point.Many owners mount it directly onto a lift post using slide-track mounts, which puts it within arm's reach of the pneumatic lock control and takes it off the floor entirely. That is the installation this compressor was shaped for. Checking that the chosen mounting point is sound, and that the supply outlet is close enough, is the customer's responsibility — nothing about a small compressor makes a wall anchor optional.One honest note on the figures. The specification table gives the three dimensions as width, height and length in that order, while the individual product data fields on this store label the same three numbers as length, width and height. The measurements agree; only the axis labels disagree. Treat 10.5" x 16" x 7" as the overall envelope, and if orientation matters for the space you have in mind, ask us and we will confirm it against the current specification sheet rather than guess.Oil-free, brushless, and what that buys youAn oil-free pump has no crankcase to check, no oil to change and no risk of oil mist reaching the air line — which matters if that air is ever pointed at a surface due to be painted. The trade, universally, is that oil-free pumps run hotter and wear faster under continuous load. On a machine intended for short, intermittent bursts, that trade is the right way round.A brushless motor removes the wearing part of a conventional motor and the arcing that goes with it, which is where a small compressor's service life usually ends. Combined with the sealed control housing, it means the unit tolerates the dust and coolant mist of a working bay rather than quietly ingesting them.Quiet enough to leave runningAround 55 dBA is the specification, and it is the feature customers notice first. A conventional compressor cycling in the corner interrupts a phone call and a technician's concentration; this one does not. In a bay with a waiting area on the other side of the wall, or a garage attached to a house with people in it, the acoustic figure is what decides whether the compressor gets left switched on or switched off and forgotten.Pressure, controls, and one figure to confirm before you orderThe compressor is fitted with an adjustable pressure regulator and dual gauges, so tank pressure and delivery pressure are both visible at a glance, and a pressure relief valve protects the system against over-pressurisation. An auto start-stop control refills the tank when pressure drops below the set threshold and shuts off when it is restored, so the machine is not running while it is not needed. A ball valve on the tank drains accumulated moisture, and an inlet air filter keeps debris out of the pump.Published figures for the maximum pressure differ, so confirm it with us if the exact figure decides your purchase. The product title and the manufacturer's own description state a maximum of 120 PSI. The product specification field on this store records 90 PSI. Those are not the same machine setting. If your application depends on the exact figure — seating a bead, or a lock cylinder with a specified minimum supply pressure — ask us before you order and we will confirm it in writing against the current specification sheet and manual. What is not in dispute is the intended duty: short bursts at moderate pressure, not sustained high-flow tool work.Perfect For Lift owners — the pneumatic safety locks on a four-post or scissor lift need a small, reliable air source and nothing more. Home garages with no plumbed air — tyre pressures, blow-off, seat cushions, sports gear, and the jobs that do not justify a shop compressor. Mobile and roadside technicians — 110V, light, and it fits behind a seat. Busy shops that need a second source in a bay the main air line never reached, or a quiet backup when the big machine is down. What's in the BoxThe compressor with its oil-free pump, brushless motor, sealed control housing, 0.5 Gallon tank, adjustable regulator, dual gauges, pressure relief valve, inlet air filter and ball-valve tank drain; the 42" power cord; quick-release fittings; and a wye fitting that lets two hoses run from the single outlet at once — genuinely useful when the lock line stays permanently connected and you want a second hose for a blow gun.Not supplied: hose, slide-track or post mounting hardware, and any downstream filtration or lubrication.Specifications Supply voltage 110V Tank capacity 0.5 Gallon (2 litres) Maximum pressure Stated as 120 PSI by the manufacturer's description; recorded as 90 PSI in the product specification field.

That is worth stating plainly rather than leaving as a gap on the page: a manufacturer's own declaration of conformity is a different document from an independent laboratory listing, and some insurers, facility standards and workplace inspectors ask specifically for the second on mains-powered shop equipment.For a small plug-in compressor this rarely comes up. If it does come up in your building — a leased unit with a landlord's schedule, an insurer's equipment list, a workplace inspection — tell us the requirement before you order and we will confirm what documentation exists rather than let you assume.Shipping and deliveryThis ships within the lower 48 states, free of charge. It is a small, light item by the standards of this catalogue, so receiving it is straightforward — but the same rules apply as to everything else we send.Inspect the carton before you sign for it. Damage noted on the bill of lading in front of the driver is claimable; damage discovered after a clean signature usually is not. If a home address is used, that is a residential delivery and carries a residential fee. Collection in person is also available from the pickup locations listed further down this page.WarrantyThis model is covered by the manufacturer's warranty, and the full warranty document is linked in the downloads on this page — read the term and the conditions there rather than take a summary from us, because the document is the thing that governs a claim.One rule of ours protects that cover: if the pump or the motor develops a fault, leave the unit assembled. An oil-free pump that has been opened cannot be assessed for what failed first, and a claim on a dismantled machine is a very difficult conversation. Call us, describe the symptom, and let it be looked at whole.
