The Johnson Pump 3 in 12V flange-mount bilge blower is a compact ventilation component for marine ducting systems. Its flange-mounted configuration is intended for installations where the blower needs to be secured directly at a duct connection or mounting surface. The unit is designed around 3 in ducting and a 12V electrical system, making it suitable for common small-boat ventilation layouts.
Johnson Pump specifies the blower for 3 in ducts and subjects the unit to full factory testing before shipment. That factory-test process provides an additional check on basic operation before the blower is installed onboard. The simple configuration makes it useful for replacing an existing flange-mounted blower without adding unnecessary components.
- Flange-mounted design supports direct installation
- Sized for 3 in marine ventilation ducting
