Air is compressed in the large low-pressure cylinder, cooled through an air-cooled intercooler, then finished in the small high-pressure cylinder. Two-stage compression is what lets an oil-free pump reach 145 PSIG without the discharge temperatures that destroy dry piston rings, and it does it on less horsepower per CFM than a single-stage pump would need.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHorsepower: 5 HP\u003c\/li\u003e\n\u003cli\u003eDelivery: 16.5 SCFM at 100 PSIG\u003c\/li\u003e\n\u003cli\u003ePump speed: 800 RPM\u003c\/li\u003e\n\u003cli\u003eMaximum pressure: 145 PSIG\u003c\/li\u003e\n\u003cli\u003eCylinders: 2, two stage\u003c\/li\u003e\n\u003cli\u003eBore: 4.13 in. low pressure, 2.95 in. high pressure\u003c\/li\u003e\n\u003cli\u003eStroke: 3.35 in.\u003c\/li\u003e\n\u003cli\u003eFlywheel: 16.9 in.

Piston rings are the scheduled wear item at roughly 10,000 operating hours. Keep the intercooler fins, flywheel and cooling fan clean, because the intercooler is doing real work on a two-stage oil-free pump and a fouled one pushes second-stage temperatures up and ring life down.\u003c\/p\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cp\u003eHospital and dental medical air plants, laboratory and research air, pharmaceutical and food processing, electronics and cleanroom assembly, instrument air, and any 5 HP application that needs genuinely oil-free air at full shop pressure.\u003c\/p\u003e\n\u003cp\u003eThe Powerex OPT050 two-stage oil-less pump delivers 16.5 SCFM at 100 PSIG on 5 HP, up to 145 PSIG, as a bare-pump replacement for Powerex 5 HP oil-free reciprocating compressors.\u003c\/p\u003e","brand":"AirComParts","offers":[{"title":"Default Title","offer_id":67614858215699,"sku":"P4010","price":10485.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/aircompressorstore.com\/products\/powerex-opt050-two-stage-oil-less-air-compressor-pump","provider":"Warthog Air Compressor Store","version":"1.0","type":"link"}
