That is not a side effect to be managed politely, it is the central engineering problem of the machine — heat is what thins the oil, fatigues the valves, and eventually decides how long the pump lasts. This compressor is built around getting rid of it, and the evidence is in the materials rather than the marketing: \u003cstrong\u003ecast iron cylinders with aluminium heads\u003c\/strong\u003e, a \u003cstrong\u003ehigh-efficiency fin-and-tube intercooler\u003c\/strong\u003e between the stages, and a \u003cstrong\u003emounted air-cooled aftercooler\u003c\/strong\u003e behind the pump.\u003c\/p\u003e  \u003cp\u003eIt is a 5 HP two-stage machine turning at 942 RPM on a vertical 80-gallon receiver, with a magnetic starter, stainless steel reed valves and graphite gaskets, and this part number is wound for 460V, 3-phase plant service.\u003c\/p\u003e  \u003ch3\u003eTwo metals, two jobs\u003c\/h3\u003e  \u003cp\u003eCast iron and aluminium are in this pump for opposite reasons. Iron goes where the wear happens: it is hard, it holds a bore, and its mass acts as a thermal flywheel that damps the temperature spikes of each compression cycle. Aluminium goes on top, in the heads, because aluminium conducts heat several times better than iron does — and the head is where the hot discharge air actually leaves the cylinder.\u003c\/p\u003e  \u003cp\u003eUsing one material throughout would mean accepting the wrong property somewhere. An all-aluminium pump gives up bore durability; an all-iron pump holds heat exactly where you least want it held. Splitting the job is a more expensive way to build a pump and it is the reason this class of machine survives a duty cycle that kills lighter ones.\u003c\/p\u003e  \u003ch3\u003eCooling in two places, for two different reasons\u003c\/h3\u003e  \u003cp\u003eThe intercooler sits \u003cem\u003ebetween\u003c\/em\u003e the compression stages. The first cylinder raises the air part of the way and hands it over hot; the fin-and-tube intercooler strips that heat out before the second cylinder receives it. This is not a comfort measure — compressing cool, dense air takes measurably less work than compressing hot air, so interstage cooling is what makes the second stage capable of reaching the 175 PSI maximum rating without cooking itself.\u003c\/p\u003e  \u003cp\u003eThe aftercooler sits \u003cem\u003eafter\u003c\/em\u003e the pump, and its job is about water rather than efficiency. Hot discharge air holds moisture that will condense the moment it cools, and if it cools in your pipework it condenses in your pipework. Dropping the temperature before the receiver forces that water out inside the tank, where a drain can deal with it, which is also why a compressor with an aftercooler is the sensible starting point for any air system feeding finishing tools.\u003c\/p\u003e  \u003ch3\u003eThe 460V build\u003c\/h3\u003e  \u003cp\u003eFor a given horsepower, current falls as the supply voltage rises. That is simply how electrical power behaves, and it is why larger industrial buildings distribute at 460V: the same power travels a long run on smaller conductors without excessive voltage drop, and the starter and overload devices handle a gentler load.\u003c\/p\u003e  \u003cp\u003eThe practical warning is the same one we give on every 460V machine. The motor winding and the magnetic starter are fixed at the factory and this unit cannot be converted to another service voltage on site. Put a meter on the panel, or have your electrician do it, before the order is placed — assuming a large building must be at 460V is an expensive assumption to be wrong about once a crated compressor is standing on your floor.\u003c\/p\u003e  \u003ch3\u003eWill It Fit?\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003e \u003cstrong\u003eSupply:\u003c\/strong\u003e 460V, 3-phase, and nothing else.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eCircuit:\u003c\/strong\u003e breaker and conductors sized on site by a certified electrician; we publish no figure, because the correct one depends on your run length and local code.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003ePlan area:\u003c\/strong\u003e 37\" by 24\", plus access to the belt guard and oil fill.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eHeight:\u003c\/strong\u003e 74\", with headroom above for lifting the pump at service time.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eWeight:\u003c\/strong\u003e 680 lbs dry, high on a narrow base — level slab, anchored.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eVentilation:\u003c\/strong\u003e a machine designed to reject heat has to have somewhere to reject it to.

The manufacturer’s feature list describes a fully pressure-lubricated package built around a gerotor positive-displacement oil pump; the structured specification field on this page records the oil system as splash lubricated — two different designs rather than two wordings. The tank drain is the same: the feature list and detailed specification both record an electronic automatic drain, while a summary field records none.
