Economy here means a plainer finish and a shorter options list, not a lighter pump: it is the same slow-speed cast-iron two-stage recipe, 17 CFM at 175 PSI at 700 RPM, with inserted connecting rods and centrifugal unloading. A pump that makes its air at 700 RPM instead of 1200 lives a great deal longer, and inserted rods mean the rod bearings are serviceable rather than disposable.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHorsepower: 5 HP\u003c\/li\u003e\n\u003cli\u003eDelivery: 17 CFM at 175 PSI\u003c\/li\u003e\n\u003cli\u003eSpeed: 700 RPM, slow speed\u003c\/li\u003e\n\u003cli\u003eStages and cylinders: 2 stage, 2 cylinder\u003c\/li\u003e\n\u003cli\u003eConstruction: cast iron\u003c\/li\u003e\n\u003cli\u003eConnecting rods: inserted\u003c\/li\u003e\n\u003cli\u003eUnloading: centrifugal\u003c\/li\u003e\n\u003cli\u003eMotor frame: suitable for 184T frame motors\u003c\/li\u003e\n\u003cli\u003eWeight: 240 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow it relates to the E Series\u003c\/h3\u003e\n\u003cp\u003eThe GL5 shares its ring sets and rod inserts with the ACS EC-5, so the common wear parts are the same across both pumps and the rebuild kits interchange. The AirComParts catalog lists the Gray Line as a replacement clone for the Saylor-Beall 705. Confirm the cross-reference against your own machine before ordering if you are replacing a branded OEM pump.\u003c\/p\u003e\n\u003ch3\u003eService notes\u003c\/h3\u003e\n\u003cp\u003eCentrifugal unloading suits ordinary start-stop operation, where the pressure switch stops the motor and the unloader bleeds the head so it restarts against no pressure. Do not put a centrifugal-unload pump on a constant-run, dual-control or engine-driven machine; those need head unloaders. Replace the check valve and belts with the pump, keep the intercooler and flywheel fins clean, and use compressor oil rather than automotive oil.\u003c\/p\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cp\u003eStationary shop compressors, automotive and fleet service bays, fabrication and welding shops, farm and agricultural air, and as a cost-conscious replacement pump on any 5 HP 175 PSI two-stage package taking a 184T frame motor.\u003c\/p\u003e\n\u003cp\u003eThe ACS Gray Line GL5 two-stage air compressor pump delivers 17 CFM at 175 PSI on 5 HP, in slow-speed cast iron at 700 RPM with inserted rods and centrifugal unloading.\u003c\/p\u003e","brand":"AirComParts","offers":[{"title":"Default Title","offer_id":67618155364627,"sku":"X1215","price":741.6,"currency_code":"USD","in_stock":true}],"url":"https:\/\/aircompressorstore.com\/products\/acs-gray-line-gl5-two-stage-air-compressor-pump-5-hp","provider":"Warthog Air Compressor Store","version":"1.0","type":"link"}
