TURBO IN-LINE BLOWERS The first vane axial-flow fan bilge blowers designed using aerospace technology to maximize performance. No other bilge blowers in the industry provide such powerful system output at such low power input in a compact size. • Patented in-line design – provides ventilation for engine compartments, galleys, bilges, and heads. • System airflow exceeds old-style in-line blowers by as much as 25% • Draws up to 40% fewer amps, making our Turbo blowers up to four times more efficient than competitive blowers.
