The motor is specified \u003cstrong\u003e208-230\/460V, 3 Phase\u003c\/strong\u003e — a dual-voltage winding. A building on the higher three-phase band and a building on the lower one order the same machine, and the decision is made by the electrician at connection rather than by the purchase order. If you are equipping a second site, moving premises, or buying ahead of an electrical upgrade, that is one fewer irreversible choice to get right months in advance.\u003c\/p\u003e \u003cp\u003eUnderneath it, the QRS package: an oil-injected rotary screw airend on a \u003cstrong\u003e60 Gallon\u003c\/strong\u003e horizontal receiver, rated \u003cstrong\u003e100%\u003c\/strong\u003e duty, running at \u003cstrong\u003e64 dBA\u003c\/strong\u003e, delivering \u003cstrong\u003e21.2 CFM at 150 psi\u003c\/strong\u003e. Chicago Pneumatic builds its rotary screws in Italy through Atlas Copco, which this listing describes as the world's largest air compressor manufacturer.\u003c\/p\u003e  \u003ch2\u003eTwo things to confirm before you order\u003c\/h2\u003e \u003cp\u003ePublished figures differ on both, and both change what you receive and what it costs to install, so each is set out here with its source.\u003c\/p\u003e \u003ch3\u003eIs a dryer fitted?\u003c\/h3\u003e \u003cp\u003eThe feature list on this product says \u003cstrong\u003eDryer Included\u003c\/strong\u003e. A separate specification field on the same product records the air dryer as \u003cem\u003enot\u003c\/em\u003e fitted. Those cannot both be true, and the answer is worth real money: an integrated refrigerated dryer is a substantial part of the machine's value, and if it is absent you need downstream drying before you spray anything or feed air-driven instrumentation.\u003c\/p\u003e \u003ch3\u003eWhat is the maximum pressure?\u003c\/h3\u003e \u003cp\u003eThe feature list states \u003cstrong\u003e150 psi\u003c\/strong\u003e maximum. A specification field on the same product instead records \u003cstrong\u003e145 PSI\u003c\/strong\u003e. The gap is small, but it is exactly the sort of number that gets designed into a system and then argued about later.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eOn both points: ask us before you order and we will confirm the configuration of the actual unit against the current manufacturer data sheet, in writing.\u003c\/strong\u003e Both figures stand as published until the factory sheet settles them.\u003c\/p\u003e  \u003ch2\u003eThree-phase, and what it buys beyond availability\u003c\/h2\u003e \u003cp\u003eA three-phase motor delivers power in overlapping cycles rather than the pulsing single phase gives you, so torque arrives smoothly, starting current is easier on the supply, and the motor runs cooler for the same shaft output. On a machine expected to run continuously, cooler is the operative word — heat is what ages windings and insulation.\u003c\/p\u003e \u003cp\u003eThat pairs with the \u003cstrong\u003e100%\u003c\/strong\u003e duty rating in a way that is easy to under-read. This compressor is not rated for a percentage of the hour; it is designed to run for as long as the shop is pulling air, at full output, without that shortening its life. A busy afternoon does not become a queue for pressure.\u003c\/p\u003e \u003cp\u003eThe other half of the argument is noise. At \u003cstrong\u003e64 dBA\u003c\/strong\u003e the machine can stand inside the working space instead of being pushed into an outbuilding for peace, and the shorter the pipe run from receiver to tool, the less pressure you give away getting there.\u003c\/p\u003e  \u003ch2\u003eWill It Fit? Power, space and siting\u003c\/h2\u003e \u003cp\u003eConfirming the supply, the floor and the ventilation before ordering is the buyer's responsibility. Take the first line to your electrician early — it is the one thing that cannot be improvised on delivery day.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eElectrical supply:\u003c\/strong\u003e \u003cstrong\u003e208-230\/460V, 3 Phase\u003c\/strong\u003e. If your building is single-phase only, this is the wrong variant and no amount of wiring cleverness fixes that. Conductor size and breaker rating depend on which voltage you connect and on the length of the run, and both are your electrician's call.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eTank:\u003c\/strong\u003e \u003cstrong\u003e60 Gallon\u003c\/strong\u003e, horizontal — low, wall-huggable, and easy to site under a mezzanine or a low garage ceiling.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFootprint:\u003c\/strong\u003e overall length \u003cstrong\u003e75\"\u003c\/strong\u003e.

This product's data does not claim a third-party safety listing for the packaged compressor, and we are not going to write one onto the page. What exists is the manufacturer's own specification and its factory commissioning programme.\u003c\/p\u003e \u003cp\u003eFor most buyers that is a non-issue. For a few it decides the purchase: insurers, fleet standards and some local inspectors ask for independent listing documents on hard-wired plant, and a maker's declaration is a different piece of paper. If your site works to a requirement like that, ask us first and we will confirm in writing exactly what documentation ships with this model.\u003c\/p\u003e  \u003ch2\u003eShipping and delivery\u003c\/h2\u003e \u003cp\u003eThe compressor moves as palletised freight to the lower 48 states, free of charge.\u003c\/p\u003e \u003cp\u003ePlan the unload before you buy. At \u003cstrong\u003e441 lbs\u003c\/strong\u003e this is forklift or dock work, or a pallet jack on level ground; the carrier's obligation stops at the back of the trailer. Without equipment on site, choose terminal pickup and collect it yourself. Delivery to a home address is a residential delivery and attracts a residential fee.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCheck it over before signing.\u003c\/strong\u003e Walk round the pallet with the driver present, look at the enclosure, receiver, panel and fittings, and write any damage or missing item onto the bill of lading before you sign. That note is what makes a claim possible; a clean signature says it arrived intact.\u003c\/p\u003e  \u003ch2\u003eWarranty\u003c\/h2\u003e \u003cp\u003eStandard cover is \u003cstrong\u003e1 year\u003c\/strong\u003e. A \u003cstrong\u003e5 Year\u003c\/strong\u003e term is available instead where the machine is commissioned by a factory authorized start-up, and this listing puts a typical fee of \u003cstrong\u003e$350\u003c\/strong\u003e on that visit.\u003c\/p\u003e \u003cp\u003eRead that fee as an indication rather than a price: it is described as typical, and it is charged by whoever performs the commissioning, not by us — so get a current quotation before you count on it. The start-up is also worth buying on its own terms. Rotation direction, oil level and control settings verified by someone who does it weekly is cheap insurance on a machine you intend to run continuously for years.\u003c\/p\u003e \u003cp\u003eIf something goes wrong, shut the compressor down, isolate it and speak to us before any part of it is opened. A dismantled airend cannot be assessed, and a claim on one is close to unarguable.
