Key Features & Benefits
1. High-Efficiency 24V Motor
Designed for boats with 24V battery banks, this blower draws a very low 2.2 Amps. This makes it extremely efficient for long-term use, such as exhausting heat from an engine room during a long passage or providing constant ventilation to a battery locker.
2. Ignition Protected (ISO 8846)
This blower is fully compliant with USCG 183.410 and ISO 8846 Marine standards. This means it is safe to use in environments where gasoline fumes may be present, as any internal sparks are contained within the motor
3. Quiet & Compact
The 3-inch diameter allows this blower to fit into tight spaces where larger 4-inch blowers cannot. Its radial leaf fan design is balanced to minimize vibration and noise, making it less intrusive when used near living quarters.
4. Corrosion-Resistant Materials
The motor features a nickel-plated shell, and the housing is made of a tough thermoplastic that will not rust or corrode in the humid, salty environment of a boat's bilge.

Pro-Tip for Installation:
"To maintain maximum airflow, ensure the 3-inch ducting is pulled taut and has as few bends as possible. If you are using this blower for exhausting engine room fumes, mount it as high as possible in the compartment. If you are using it to cool sensitive electronics, ensure the intake air is pulled from a cool, dry area of the boat rather than the humid bilge."
