Key Features & Benefits

1. High-Volume Performance

Moving 250 CFM , this blower is designed to overcome the resistance of long ducting runs. It is significantly more powerful than standard 3-inch blowers, making it the preferred choice for larger engine rooms or high-heat environments.

2. Versatile "Flexmount" Installation

The mounting bracket is separate from the blower body, allowing you to:

Mount the bracket to a floor, ceiling, or bulkhead.
Rotate the blower discharge port to the exact angle needed to align with your hoses.
This prevents "kinking" of the 4-inch ducting, which is the leading cause of reduced airflow.

3. Safety & Compliance

Ignition Protected: Meets USCG 183.410 and ISO 8846 Marine standards. It is safe for use in gasoline engine compartments.
Corrosion Resistant: Built with a nickel-plated motor and a tough, reinforced plastic housing to survive the salt-air environment of a bilge.

Pro-Tip for Installation:

"To ensure maximum airflow, keep the 4-inch intake hose as straight as possible. If you are using this blower for engine room ventilation, it is best practice to have the intake located in the lower third of the bilge to exhaust heavier-than-air fuel vapors, while the blower itself should be mounted as high as possible to protect it from bilge water."

Engine compartment ventilation
Bilge and battery compartment airflow
Cabin and locker ventilation
RV and camper ventilation systems
Utility and enclosed equipment spaces
