Attwood Turbo 4000, 4" Exhaust Blower - AW-1749-4

The Attwood Turbo 4000 Series II is a high-performance, water-resistant in-line exhaust blower designed to provide efficient ventilation for confined spaces. Originally engineered for marine environments to remove fumes and heat from engine compartments, bilges, galleys, and heads, this versatile blower is also widely utilized in specialty vehicle applications, including emergency vehicles and ambulances where reliable airflow is critical.

Featuring a patented in-line design and an advanced five-blade fan, the Turbo 4000 maximizes airflow while operating at significantly lower noise levels than traditional blowers. Its durable housing is reinforced with stiffening ribs to prevent deformation, and the nickel-plated motor ensures long-lasting corrosion resistance.
