{"product_id":"chicago-pneumatic-qrs3-0hp-3-air-compressor","title":"Chicago Pneumatic Air Compressor QRS3.0HP-3 3 HP Rotary Screw 3 Phase","description":"\u003ch2\u003eChicago Pneumatic QRS3.0HP-3: the smallest step into continuous-duty air on three-phase power\u003c\/h2\u003e \u003cp\u003eThere is a size of workshop that needs air all day but does not need a lot of it at once — a one- or two-technician bay, a fabrication corner, a wheel and tyre operation. That shop is normally sold a piston compressor, and it spends the next five years listening to it labour. The QRS3.0HP-3 is the alternative: \u003cstrong\u003e3 HP\u003c\/strong\u003e of rotary screw rated \u003cstrong\u003e100%\u003c\/strong\u003e duty, delivering \u003cstrong\u003e8.5 CFM at 150 psi\u003c\/strong\u003e at \u003cstrong\u003e61 dBA\u003c\/strong\u003e, on \u003cstrong\u003e208-230\/460 Volt\u003c\/strong\u003e three-phase supply.\u003c\/p\u003e \u003cp\u003eThe defining figure is the duty rating, not the horsepower. This machine has no rest cycle to respect. Where a piston unit of comparable output has to stop and cool — and drops your line pressure while it does — the screw airend keeps turning for as long as the shop draws air. Small does not mean intermittent here.\u003c\/p\u003e  \u003ch2\u003eSizing it honestly: what 8.5 CFM runs, and what it does not\u003c\/h2\u003e \u003cp\u003eAn air rating is only useful next to a list of tools, so here is the plain version. \u003cstrong\u003e8.5 CFM at 150 psi\u003c\/strong\u003e comfortably supports intermittent hand-tool work — impact wrenches, ratchets, blow guns, tyre inflation, a die grinder used in bursts — for one or two people working steadily.\u003c\/p\u003e \u003cp\u003eWhat deserves more thought is anything that consumes air continuously rather than in bursts: sustained sanding, media blasting, or a spray gun running for long stretches. Those draw at a constant rate and will out-consume a machine of this size if you plan optimistically. The correct method is boring and reliable: add up the consumption of the tools you will genuinely run \u003cem\u003eat the same time\u003c\/em\u003e, then compare. Send us the list and we will check it against this model before you order rather than after the pallet has arrived.\u003c\/p\u003e \u003cp\u003eBeing deliberately clear about that is more useful to you than a page implying this compressor does everything. It is a well-built machine for a defined job.\u003c\/p\u003e  \u003ch2\u003eConfirm the dryer before you order\u003c\/h2\u003e \u003cp\u003ePublished entries for this machine differ: the feature list states an \u003cstrong\u003eintegrated air dryer\u003c\/strong\u003e, while a separate specification field records the dryer as not fitted. Both are given here, attributed, so nothing rests on the version that reads better.\u003c\/p\u003e \u003cp\u003eGet it settled before you order, because it changes both the price and the plumbing. \u003cstrong\u003eAsk us and we will confirm the dryer configuration of the specific unit we would ship, in writing.\u003c\/strong\u003e If no dryer is fitted, downstream air treatment is easy enough to add — but only if you know it needs adding before you commission the installation.\u003c\/p\u003e  \u003ch2\u003eThree-phase, an approved panel, and a certified receiver\u003c\/h2\u003e \u003cp\u003eThe supply requirement is the first hurdle and the one nobody can engineer around after delivery: this variant is built for three-phase service. If your building has single-phase only, this is the wrong model and no wiring arrangement fixes it.\u003c\/p\u003e \u003cp\u003eWhat you get in return is a motor that runs cooler and starts more gently than its single-phase equivalent — three-phase power arrives in overlapping cycles instead of pulses, so torque is smooth and starting current is easier on the supply. On a machine designed to run continuously, cooler running is directly a longevity argument, because heat is what ages windings.\u003c\/p\u003e \u003cp\u003eTwo supporting specifications are worth reading precisely rather than skimming. The control panel is approved by UL and cUL: that covers the electrical control gear, which is what an electrician and, in some jurisdictions, an inspector will look at. The receiver is an \u003cstrong\u003eASME\/CRN\u003c\/strong\u003e tank, which is the pressure-vessel side of the machine. The motor itself is a \u003cstrong\u003eTEFC Baldor\u003c\/strong\u003e — totally enclosed and fan cooled, from a manufacturer with a parts and service network, which is the right answer for a motor living in dust and aerosol.\u003c\/p\u003e  \u003ch2\u003eWill It Fit? Supply, space and siting\u003c\/h2\u003e \u003cp\u003eConfirming power, floor and ventilation before the machine ships is the buyer's responsibility.

Insurers, fleet standards and certain local inspectors ask for independent listing documentation on hard-wired plant, and a manufacturer's own declaration is not that document. Installation to local electrical code remains your electrician's responsibility. If you work to a requirement of that kind, tell us before you order and we will establish in writing what this model can actually evidence.\u003c\/p\u003e  \u003ch2\u003eShipping and delivery\u003c\/h2\u003e \u003cp\u003ePalletised freight to the lower 48 states, priced live at checkout against the address you enter rather than estimated from a zone chart.\u003c\/p\u003e \u003cp\u003eDecide how the pallet comes off the truck before you commit. \u003cstrong\u003e397 lbs\u003c\/strong\u003e means a forklift, a dock, or a pallet jack on level ground; the driver is not equipped to lower it for you and is not expected to.
