The Jabsco 4" 250 CFM Flangemount Heavy Duty Blower is a powerful, reliable marine ventilation blower engineered to deliver high airflow in demanding onboard environments. Designed for continuous-duty use, this 12V blower provides effective removal of heat, fumes, moisture, and odors from engine rooms, bilges, cabins, and enclosed compartments.
With a robust 250 CFM airflow rating and rugged marine-grade construction, this blower is an ideal solution for both safety-critical engine ventilation and general onboard air circulation.
Capable of moving up to 250 cubic feet per minute, this heavy-duty blower ensures rapid air exchange, helping maintain safe operating conditions in engine compartments and improving overall comfort throughout the vessel.
The flangemount configuration allows for solid, vibration-resistant mounting directly to bulkheads or flat surfaces. This design provides a clean, secure installation and is well-suited for permanent ventilation setups in tight marine spaces.
Built for continuous operation, the blower features a long-life motor and reinforced housing. Its design minimizes vibration and noise while delivering consistent performance over extended periods of use.
Manufactured by Jabsco, this blower is ignition protected and constructed with corrosion-resistant materials to withstand harsh saltwater and high-humidity environments. It meets marine safety requirements for use in engine compartments.

Most consumer-grade bilge blowers are rated for short-term use (e.g., 15 minutes before engine start). The 35760-0092 is built for continuous duty, making it ideal for engine room cooling, constant head/galley exhaust, or moisture control in electronics lockers.
This blower is fully compliant with USCG and ISO 8846 Marine standards for Ignition Protection.6 This means it is safe to install in engine compartments containing gasoline-powered engines where fuel vapors may be present.
Despite its low 11.0 Amp draw, this blower moves a massive 250 CFM (Cubic Feet per Minute). Its radial leaf fan design provides high pressure, allowing it to move air effectively even through long or complex ducting runs.

"To get the full 250 CFM performance, avoid sharp $90^\circ$ bends in your ducting. For every sharp turn, you lose approximately 15-20% of your actual airflow. If you must turn the ducting, use long, sweeping curves and ensure the 4-inch hose is pulled tight so the internal wire ribbing doesn't create excessive turbulence."
