{"product_id":"schulz-560hv20-3-air-compressor","title":"Schulz Air Compressor 560HV20-3 5 HP 60 Gallon Oil Free Two Stage 230V 3 Phase","description":"\u003ch2\u003eSchulz 560HV20-3: oil-free air, running on a 230V 3-phase supply\u003c\/h2\u003e\u003cp\u003eTwo requirements that rarely arrive in the same machine meet in this one. The pump is \u003cstrong\u003eoil-free\u003c\/strong\u003e, so nothing in the compression chamber can carry over into the air line. The motor is \u003cstrong\u003e3-phase\u003c\/strong\u003e on a \u003cstrong\u003e230V\u003c\/strong\u003e supply, which is the service a great many older industrial and light-manufacturing buildings already have. If both of those describe your situation, the list of candidates is short, and this is on it.\u003c\/p\u003e\u003cp\u003eThe rest of the specification: \u003cstrong\u003e5 HP\u003c\/strong\u003e, a 60-gallon horizontal steel tank, \u003cstrong\u003e20 CFM at 90 PSI\u003c\/strong\u003e with a ceiling of \u003cstrong\u003e120 PSI\u003c\/strong\u003e, and a belt-driven cast iron pump turning at \u003cstrong\u003e1,050 RPM\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eWhy a 3-phase motor suits an oil-free pump in particular\u003c\/h3\u003e\u003cp\u003eThe pairing is not a coincidence of the catalogue. It addresses a specific weakness.\u003c\/p\u003e\u003cp\u003eA dry-running pump has no oil film to carry away frictional heat, so it depends on slow speed and iron mass to stay within itself — and it is least happy when it is asked to start, repeatedly, against tank pressure. That is exactly the duty a compressor sees in a clinic, a laboratory or a process line, where a lot of small demands mean the machine cycles many times a day rather than running in long steady stretches.\u003c\/p\u003e\u003cp\u003eA 3-phase motor answers that duty. Its torque is continuous rather than pulsed, so it breaks the pump away smoothly instead of jerking it into motion, and it does so without a start capacitor or a centrifugal starting switch — the two components most likely to fail on a single-phase compressor motor after tens of thousands of starts. It also spreads current across three conductors rather than two, so the windings run cooler through a heavy cycling day. On plant nobody visits, fewer things that can fail beats any headline figure.\u003c\/p\u003e\u003ch3\u003eConfirm the supply before you order\u003c\/h3\u003e\u003cp\u003eThe phase and voltage on this listing are a specification, not a preference. A motor wound for a \u003cstrong\u003e230V 3-phase\u003c\/strong\u003e supply will not simply adapt to a different one — mismatched, it draws the wrong current, overheats and takes its insulation with it, and the remedy is a transformer or a new motor on top of freight you have already paid.\u003c\/p\u003e\u003cp\u003eThe check is quick. Have a certified electrician measure line-to-line at the panel that will feed the machine and confirm both the phase and the voltage, rather than inferring them from the building's age or from a label on other plant. Schulz recommends a \u003cstrong\u003e40 Amp\u003c\/strong\u003e breaker for this model — treat that as the manufacturer's starting point and let your electrician size the circuit properly against your conductor, run length and local code. If the measurement comes back as something else, contact us before ordering and we will point you at the correct variant.\u003c\/p\u003e\u003ch3\u003eConfirm the regulator before you order\u003c\/h3\u003e\u003cp\u003ePublished figures for the regulator differ: the copy that has been on this page lists a \u003cem\u003ebuilt-in regulator switch\u003c\/em\u003e; the manufacturer specification field we hold records the regulator as \u003cem\u003eNo\u003c\/em\u003e. Both are shown here, each attributed to its source. \u003cstrong\u003eIf a factory-fitted regulator decides your purchase, confirm it with us before ordering\u003c\/strong\u003e and we will get it in writing from Schulz. A regulator can be fitted downstream easily enough — the point is that you should know what arrives in the crate.\u003c\/p\u003e\u003ch3\u003eRead the pressure band before you commit\u003c\/h3\u003e\u003cp\u003eRated flow is \u003cstrong\u003e20 CFM at 90 PSI\u003c\/strong\u003e; the maximum is \u003cstrong\u003e120 PSI\u003c\/strong\u003e. Within that band it comfortably runs air tools, blow-off and cleaning, pneumatic actuators, laboratory and dental equipment and general shop work.\u003c\/p\u003e\u003cp\u003eAbove it, it does not. The oil-lubricated two-stage compressors in this range reach considerably higher pressure, and if your work depends on the top of that band — certain plasma cutters, high-pressure test equipment — you want one of those and not this. Buy for the pressure you actually use, and buy the air quality you cannot add afterwards.\u003c\/p\u003e\u003ch3\u003eWill It Fit?\u003c\/h3\u003e\u003cul\u003e \u003cli\u003e \u003cstrong\u003eFloor:\u003c\/strong\u003e 66.9 inches by 21.3 inches.

Both exist for the same reason: a compressor tank is a cool vessel full of humid air, so it accumulates water, and water on bare steel produces rust in a workshop and a contamination question in a clinic or a food area. Coating the inside of the vessel rather than only painting the outside is a deliberate choice for those rooms. It does not, however, excuse you from draining the tank on a schedule, which remains the maintenance job that repays the least effort.\u003c\/p\u003e\u003ch3\u003ePerfect For\u003c\/h3\u003e\u003cul\u003e \u003cli\u003e \u003cstrong\u003eIndustrial and light-manufacturing buildings with an existing 230V 3-phase supply\u003c\/strong\u003e that need air with no oil in it.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eLaboratories, clinics and dental practices\u003c\/strong\u003e operating from a plant room, where the machine runs unattended and cycles frequently.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFood handling, packaging and process lines\u003c\/strong\u003e where compressed air contacts the product.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFacilities teams tired of oil changes\u003c\/strong\u003e on plant they can only reach out of hours.\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003eWhat Is Fitted\u003c\/h3\u003e\u003cul\u003e \u003cli\u003eOil-free belt-drive cast iron pump, two-stage, 1,050 RPM\u003c\/li\u003e \u003cli\u003e5 HP electric motor, 230V 3-phase\u003c\/li\u003e \u003cli\u003e60-gallon horizontal steel air tank with internal antibacterial powder coating\u003c\/li\u003e \u003cli\u003eASME safety valve and tank drain\u003c\/li\u003e \u003cli\u003eBuilt-in regulator switch (see the note above)\u003c\/li\u003e \u003cli\u003eIntake air filter\u003c\/li\u003e \u003cli\u003eSwedish steel valves\u003c\/li\u003e \u003cli\u003eEpoxy coated construction\u003c\/li\u003e \u003cli\u003ePressure gauge\u003c\/li\u003e \u003cli\u003e1\/2-inch tank outlet\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ch4\u003eOutput\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eDelivered air\u003c\/th\u003e \u003ctd\u003e20 CFM\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eRated at\u003c\/th\u003e \u003ctd\u003e90 PSI\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eMaximum pressure\u003c\/th\u003e \u003ctd\u003e120 PSI\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003ePump speed\u003c\/th\u003e \u003ctd\u003e1,050 RPM\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e\u003c\/table\u003e\u003ch4\u003eMotor, pump and power\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eMotor\u003c\/th\u003e \u003ctd\u003e5 HP electric\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eVoltage\u003c\/th\u003e \u003ctd\u003e230V AC\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003ePhase\u003c\/th\u003e \u003ctd\u003e3-phase\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eRecommended breaker\u003c\/th\u003e \u003ctd\u003e40 Amp\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003ePump\u003c\/th\u003e \u003ctd\u003eTwo-stage, belt drive, solid cast iron\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eLubrication\u003c\/th\u003e \u003ctd\u003eOil free\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eAir dryer\u003c\/th\u003e \u003ctd\u003eNo\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e\u003c\/table\u003e\u003ch4\u003eTank and dimensions\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eTank\u003c\/th\u003e \u003ctd\u003e60-gallon, horizontal steel\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eTank outlet\u003c\/th\u003e \u003ctd\u003e1\/2-inch\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eLength\u003c\/th\u003e \u003ctd\u003e66.9 inches\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eWidth\u003c\/th\u003e \u003ctd\u003e21.3 inches\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eHeight\u003c\/th\u003e \u003ctd\u003e40.6 inches\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eWeight\u003c\/th\u003e \u003ctd\u003e447 lbs\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eCertification, stated plainly\u003c\/h3\u003e\u003cp\u003eThe certification recorded for this compressor is ASME, covering the safety valve and the air receiver.

That boundary matters more on this model than on a workshop compressor, for two reasons at once — it is a fixed 3-phase electrical installation, and it is destined for the kind of room that gets inspected against a facility standard. If a specific listing or approval is required by your regulator, insurer or client, ask us before ordering and we will confirm in writing exactly what this unit carries.
