Provide ventilation for engine compartments, galleys, bilges, and heads.Designed using aerospace technology for high-efficiency. In independent testing at Western Michigan University, these blowers were proven to be as much as four times more efficient than other in-line models. Offered in a standard or in a water resistant design for use in bilge applications. Mounting feet allow vertical or horizontal installation in confined spaces. Install with #10 fasteners.Key FeaturesNickel-plated motor can for corrosion resistanceStiffening ribs to reduce housing distortionMotor cap to seal wires and motor for water resistanceFive-blade fan maximize airflow and efficiencyTabs in intake and exhaust hold ventilation hose to clamp firmly in placeLow amp draw motor for longer blower and battery lifeBuilt-in mounting feet allow easy vertical or horizontal install
