It uses Johnson Pump's radial flow design with a squirrel cage type blower wheel, which produces substantial airflow at relatively low RPM compared to lighter inline tunnel type blowers, resulting in a quieter operating blower well suited to living spaces aboard as well as machinery spaces. The massive 3 inch diameter motor idles at 3100 RPM and is built for long service life, moving 112 CFM through 3 inch ducting.\u003c\/p\u003e\u003cp\u003eThis is the flange mount configuration: a conventional outlet flange mounts directly to the exhaust opening in the hull, and molded mounting brackets simplify installation. The housing is molded from tough glass filled composite resin for durability in the marine environment, and the shaft and hardware are stainless steel. The blower is ignition protected and factory tested, and it meets and exceeds NMMA, ABYC, ISO 8846, CE, and USCG specifications. The Johnson Pump 54124 is a direct replacement for older Mayfair Flange Mount Bilge Blowers.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Johnson Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 54124\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Bilge Blower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Style:\u003c\/strong\u003e Flange Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Diameter:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow:\u003c\/strong\u003e 112 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Speed:\u003c\/strong\u003e 3100 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Draw:\u003c\/strong\u003e 5.0 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Size:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material:\u003c\/strong\u003e Glass-filled composite resin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft and Hardware:\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Protected:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 13 inches L x 10 inches W x 9 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.89375 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 729321541244\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e Meets NMMA, ABYC, ISO 8846, CE, and USCG specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Johnson Pump 54124 used for?\u003c\/strong\u003e The Johnson Pump 54124 is a flange mount bilge blower used to ventilate bilges, engine compartments, heads, and galleys by drawing out fumes and moisture.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much airflow does the 54124 blower produce?\u003c\/strong\u003e The 54124 produces 112 CFM of airflow through 3 inch ducting, driven by a 3 inch diameter motor idling at 3100 RPM.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 54124 a flange mount or remote mount blower?\u003c\/strong\u003e The 54124 is the flange mount version, with a conventional outlet flange that mounts directly to the exhaust opening in the hull and molded mounting brackets for installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage and amperage does this blower require?\u003c\/strong\u003e This blower operates on 12 volts and draws 5.0 amps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Johnson Pump 54124 ignition protected?\u003c\/strong\u003e Yes, the 54124 is ignition protected, which matters for a blower installed near an engine compartment or fuel system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the housing made of?\u003c\/strong\u003e The 54124 housing is molded from tough glass filled composite resin, and the shaft and hardware are stainless steel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 54124 replace an older Mayfair blower?\u003c\/strong\u003e Yes, the Johnson Pump 54124 Flange Mount Bilge Blower is a direct replacement for older Mayfair Flange Mount Bilge Blowers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat marine standards does this blower meet?\u003c\/strong\u003e The 54124 meets and exceeds NMMA, ABYC, ISO 8846, CE, and USCG specifications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 54124 blower weigh?\u003c\/strong\u003e The Johnson Pump 54124 weighs 2.89375 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 54124 be used in the cabin, not just the bilge?\u003c\/strong\u003e Yes, the low noise level of the 54124's radial flow design makes it a good choice as an exhaust fan in heads and galleys as well as bilges and engine compartments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 54124 bilge blower?\u003c\/strong\u003e The Johnson Pump 54124 measures 13 inches by 10 inches by 9 inches.\u003c\/p\u003e","brand":"Johnson Pump","offers":[{"title":"Default Title","offer_id":49028227760347,"sku":"MAY-54124","price":82.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/54124__56413.1722372460.500.750.jpg?v=1785164657","url":"https:\/\/www.goodvibesmarina.com\/products\/johnson-pump-54124-bilge-blower-flange-mount-3-inch-112-cfm-12-volt","provider":"Good Vibes Marina","version":"1.0","type":"link"}
