That makes it the replacement pump for the lighter Unoair portables and for any 2 to 5 HP build where the motor you already own is a standard small frame.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHorsepower: 2 to 5 HP\u003c\/li\u003e\n\u003cli\u003eDelivery: 8 CFM at 100 PSI\u003c\/li\u003e\n\u003cli\u003eStages and cylinders: single stage, 2 cylinder\u003c\/li\u003e\n\u003cli\u003eConstruction: cast iron\u003c\/li\u003e\n\u003cli\u003eMotor frame: suitable for 56 and 145 frame motors\u003c\/li\u003e\n\u003cli\u003eWeight: 53 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eUH30D or UH30\u003c\/h3\u003e\n\u003cp\u003eThe frame is the deciding spec. The UH30D takes 56 and 145 frame motors and makes 8 CFM at 100 PSI. The standard UH30 (AirComParts U1261) takes a 182 frame motor and makes 13.8 CFM. Measure the motor shaft height and the mounting bolt pattern before ordering, because the two pumps are not interchangeable on a frame basis even though they share a model name. ACP lists this one as the slotted version, which is how the mounting accommodates the smaller frames.\u003c\/p\u003e\n\u003ch3\u003eService notes\u003c\/h3\u003e\n\u003cp\u003eCheck oil before every run and change it on the manufacturer's schedule. Keep the intake filter clean. Single stage means this pump is happiest below 135 PSI; asking a single-stage pump to make and hold high pressure is what burns valves and rings.\u003c\/p\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cp\u003eReplacement pump for Unoair portables and shop-cart machines, 2 to 5 HP single-stage builds on 56 or 145 frame motors, farm and ranch compressors, and service-truck air.\u003c\/p\u003e\n\u003cp\u003eThe Unoair UH30D single-stage air compressor pump delivers 8 CFM at 100 PSI on 2 to 5 HP, in cast iron with two cylinders, for 56 and 145 frame motors.\u003c\/p\u003e","brand":"AirComParts","offers":[{"title":"Default Title","offer_id":67616197869843,"sku":"U1286","price":289.49,"currency_code":"USD","in_stock":true}],"url":"https:\/\/aircompressorstore.com\/products\/unoair-uh30d-single-stage-air-compressor-pump-2-5-hp","provider":"Warthog Air Compressor Store","version":"1.0","type":"link"}
