A.: The Attwood Turbo 4000 Bilge Blower is designed to ventilate your boat’s bilge and engine compartment by removing harmful fumes and moisture. This 12 Volt in-line blower with a 100 mm (4-inch) ducting size ensures proper airflow, helping to prevent the buildup of explosive gases and maintain a safe environment on your vessel.
Q. What size ducting does the Attwood Turbo 4000 Bilge Blower fit?
A: This bilge blower is compatible with 100 mm (4-inch) ducting, making it suitable for a wide range of marine vessels. Ensure your boat’s ventilation system matches this size for optimal performance.
Q. How do I install the Attwood Bilge Blower Turbo 4000 on my boat?
A: Installation is straightforward. Mount the blower in a secure location in your boat’s bilge or engine compartment, connect it to a 12 Volt power source, and attach the 100 mm ducting to direct air out of the compartment. Always follow the manufacturer’s instructions and ensure the blower is positioned to avoid water ingress. For added safety, consult a marine electrician if you’re unsure about wiring.
Q. Is the Attwood Turbo 4000 Bilge Blower water-resistant?
A: Yes, the Attwood Turbo 4000 is designed with water-resistant materials to withstand the harsh marine environment. Its corrosion-resistant construction ensures durability even when exposed to moisture and saltwater conditions.
Q. Is the Attwood Bilge Blower noisy during operation?
A: No, the Attwood Turbo 4000 is designed to minimise noise with its advanced fan technology. While some sound is inevitable during operation, it is engineered for quiet performance compared to older or less efficient models.
Q. Why is a bilge blower important for boat safety?
A: A bilge blower is critical for boat safety as it removes potentially explosive gasoline vapours and other harmful fumes from the engine compartment and bilge area. Proper ventilation reduces the risk of fire or explosion, ensuring compliance with marine safety standards.
Q. Can I use the Attwood Turbo 4000 Bilge Blower continuously?
A: While the blower is built for durability, it is typically recommended to operate it for a few minutes (up to 20 minutes followed by 20 minutes cooldown) before starting your engine to clear fumes, and as needed during operation based on your boat’s ventilation requirements. Refer to your boat’s safety guidelines and the product manual for specific usage recommendations.
Warning: This bilge blower is designed for intermittent use only. Continuous operation may reduce its lifespan or cause overheating.
Boat Hut Insight
While the Attwood Turbo 4000 offers excellent efficiency and water resistance, one thing to consider is the placement of your blower relative to the engine and fuel tanks. Installing the blower so that it vents fumes directly overboard and away from air intakes or living spaces is crucial. A common mistake is to install the blower too close to the engine’s air intake or cabin vents, which can defeat the purpose of ventilation and create a safety hazard. Also, if you have a noisy boat, this blower’s quieter operation can be a welcome relief — but don’t expect complete silence; it’s still working hard to keep you safe!
Tip: When choosing ducting and clamps, opt for marine-grade materials resistant to UV and saltwater corrosion to maintain your blower’s performance over time.
