Boat owners, this AIR V radial blower is exactly what you need for proper engine compartment ventilation! Running on 12V power and drawing 12.5 amps, this heavy-duty marine blower moves an impressive 324 CFM of air to clear out dangerous fumes before startup. The flange mount design makes installation straightforward, and the 4-inch hose connection fits standard marine ventilation systems perfectly. Measuring 11.5 inches high by 10 inches wide by 6 inches deep, it's compact enough to fit in tight spaces but powerful enough to do the job right. What really stands out is the construction - double ball bearing motor, high-impact anti-shock ABS body, and stainless steel shaft and screws that can handle the harsh marine environment. This isn't some cheap blower that'll quit after one season; it's built for continuous duty and can handle air intake or extraction in bilges, galleys, accommodation areas, and other compartments. It's the Johnson Pump 80-47417-01 replacement that marine professionals trust. Whether you're replacing a worn-out blower or upgrading your boat's safety systems, this radial blower delivers reliable performance when you need it most. Proper ventilation isn't just about comfort - it's about safety, and this blower gives you peace of mind knowing your engine compartment is properly cleared of explosive fumes before you turn that key.
