attwoodmarine.com WATER SYSTEMS & VENTILATION 36 Turbo In-Line Blowers The first vane axial-flow fan bilge blowers designed using aerospace technology to maximize performance. No other bilge blowers in the industry provide such powerful system output at such low power input in a compact size. • Patented in-line design – provides ventilation for engine compartments, galleys, bilges, and heads • System airflow exceeds old-style in-line blowers by as much as 25% • Draws up to 40% fewer amps, making our Turbo blowers up to four times more efficient than competitive blowers • Marine ignition protected Note- In system = 3 ft of duct with one 90° bend, a collector box and louvered vent on discharge side of blower at 13.6V DC 1731 1747 Nickel-plated motor can for greater corrosion resistance Tabs on intake and exhaust hold ventilation hose/ clamp firmly in place Stiffening ribs reduce housing distortion Motor cap seals wires and motor for better water resistance Caulked and tinned wires for improved corrosion resistance Low amp draw motor for longer blower and battery life Five-blade fan maximizes airflow and efficiency Blade sweep and pitch are engineered for a high lift coefficient, increasing airflow speed Built-in mounting feet allow easy vertical or horizontal installation Pump Dimensions Model No. A B C D Turbo 3000 3-5/8" 4-1/2" 5-1/16" 3" Turbo 4000 4-17/32" 5-1/2" 6-1/16" 4" Specifications Model No. Rated Voltage CFM Open Flow CFM In System* Current Draw Amps Fuse Size Wave Length Turbo 3000 12V nominal 120 90 2.6 4A 7-1/2" 13.6V design 145 100 3.1 4A 7-1/2" Turbo 4000 12V nominal 200 100 2.5 5A 7-1/2" 13.6V design 230 125 2.9 5A 7-1/2" 24V nominal 200 100 1.5 3A 7-1/2" 27.2V design 230 125 2.0 3A 7-1/2" Turbo 3000 Series For 3" I.D. ventilation hose.
