Provides outstanding ventilation airflow for areas such as engine compartments, galleys, bilges, and heads 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, resulting in increased airflow speed for optimized ventilation System airflow exceeds older-style in-line blowers by as much as 25 percent Up to four times more efficient than competitive blowers as it draws up to 40 percent fewer amps Marine ignition protected and has built-in mounting feet for easy vertical or horizontal installation Do not operate in area of high heat over 160º F (71º C)
