This Attwood Turbo 4000 Series II In-Line Blower provides outstanding ventilation airflow for areas such as engine compartments, galleys, bilges, and heads. It features a patented, in-line design and the 5-blade fan maximizes airflow and efficiency. The blade sweep and pitch are engineered for a high lift coefficient, which ends up in increased airflow speed for optimized ventilation. It matches the airflow of competitive in-line blowers with significantly reduced noise output. For added durability, it has an engineered plastic housing that resists deformation right through installation, and prevents blade-to-housing interference. No other bilge blowers in the industry provide such powerful system output at such low power input in a compact size. System airflow exceeds older-style in-line blowers by as much as 25 percent. It’s also as much as four times more efficient than competitive blowers as it draws as much as 40 percent fewer amps. This blower is marine ignition secure and has built-in mounting feet that permit easy vertical or horizontal installation. This 12-volt, water-resistant white blower is intended to be used with 4-inch interior diameter ventilation hose. It installs with #10 fasteners. Attwood Corporation has been an award-winning leader in engineering, testing, and manufacturing of the best quality marine products for over 100 years. We deliver secure and reliable lighting, fuel systems, water systems, seating & pedestals, swim ladders, custom upholstery, and general marine accessories which are easy to install and meet regulatory compliance.
