Johnson Pump 3" In-Line Blower - 158CFM - 12V

The Johnson Pump 3" In-Line Blower is purpose-built ventilation equipment designed for cruisers, cabin boats, and enclosed marine spaces where engine fumes and moisture accumulation pose safety and comfort concerns. Proper bilge and engine compartment ventilation is essential for any experienced boater, as stale air can lead to mold, corrosion, and dangerous vapor buildup.

This compact 12-volt blower effectively addresses these issues by providing reliable, continuous air movement that keeps below-deck environments fresh and dry. Engineered with an inline 3-inch ducting connection, the Johnson Pump 3" In-Line Blower delivers 158 cubic feet per minute (CFM) of airflow, making it suitable for mid-size cabin spaces and engine compartments without excessive noise or current draw.

Boaters operating diesel or gasoline engines, especially in humid climates or during seasonal storage, will find this blower invaluable for long-term hull and engine preservation. Its inline configuration ensures quiet operation and straightforward ductwork integration, minimizing vibration transfer to the hull and maintaining a peaceful cabin environment.
