Johnson Pump 54124 Bilge Blower Flange Mount, 3 Inch, 112 CFM, 12 Volt

The Johnson Pump 54124 Bilge Blower Flange Mount is a 12 volt ventilation blower built to clear fumes and moisture from bilges, engine compartments, heads, and galleys. 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.

This 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.
