4.2 Ducting
- Connect 3-inch (76 mm) diameter ducting to both the intake and exhaust ports of the blower.
- Use marine-grade ducting and secure connections with clamps to prevent air leaks.
- Ensure ducting runs are as straight and short as possible to maximize airflow efficiency. Avoid sharp bends or kinks.
- Position the intake in the lowest part of the compartment to effectively remove heavier-than-air fumes.
4.3 Electrical Wiring
The blower operates on 12V DC power. Refer to the wiring diagram below for correct connections.
- Connect the red wire from the blower to the positive (+) terminal of your 12V DC power source, through a suitable switch and a 5.0A fuse.
- Connect the black wire from the blower to the negative (-) terminal of your 12V DC power source.
- Ensure all electrical connections are watertight and corrosion-resistant, using marine-grade connectors and heat shrink tubing.
- The motor shaft is sealed to block moisture intrusion, enhancing longevity.

5. Operation
To operate the SEAFLO bilge air blower:
- Before starting your engine, activate the bilge blower for at least four minutes to evacuate any accumulated fumes from the engine compartment.
- Ensure the blower is running smoothly and quietly. The unit is designed for balanced, quiet airflow with a noise level of approximately 45 dB.
- The blower delivers 130 CFM (Cubic Feet per Minute) of airflow with a maximum draw of 2.5A, providing efficient ventilation without excessive battery drain.
- After engine startup, the blower can be turned off, or operated intermittently as needed for continued ventilation.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your blower.
- Monthly Inspection: Check the blower housing and ducting for any signs of damage, cracks, or obstructions. Ensure all mounting screws are tight.
- Wiring Check: Inspect electrical connections for corrosion or loose wiring. Clean any corrosion and re-secure connections as necessary.
- Impeller Cleaning: If airflow appears reduced, disconnect power and carefully remove any debris (leaves, dust, etc.) from the impeller blades. The blower features a four-blade impeller designed for efficient airflow.
- Housing Material: The blower is constructed from corrosion-resistant ABS plastic, which requires minimal maintenance. Clean the exterior with a damp cloth if needed.
