Attwood 1749-4 Turbo 4000 Series II Blower for 4-Inch Vent Hose, Water Resistant, 12-Volt

The Attwood Turbo 4000 Series II In-Line Blower is specifically designed to provide exceptional ventilation airflow in various areas such as engine compartments, galleys, bilges, and heads. Its patented in-line design and 5-blade fan are engineered to maximize airflow and efficiency. The blade sweep and pitch are carefully calculated to create a high lift coefficient, resulting in increased airflow speed for optimized ventilation. This innovative design allows the blower to match the airflow of competitive models while significantly reducing noise output.

In terms of durability, the blower features an engineered plastic housing that resists deformation during installation and prevents blade-to-housing interference. This ensures a longer lifespan and consistent performance. The blower also boasts a powerful system output at a low power input, outperforming older-style in-line blowers by up to 25 percent and being up to four times more efficient than competitive models, drawing up to 40 percent fewer amps.

The blower is marine ignition protected and comes with built-in mounting feet, allowing for easy vertical or horizontal installation. This 12-volt, water-resistant white blower is designed for use with 4-inch interior diameter ventilation hose and can be easily installed with #10 fasteners. It is also equipped with features such as 7/8" I.D. thru-hull ideal for livewell drains, brass snaps, and plates. However, it is important to note that this blower is not intended for use with chemicals or fuels.
