The Jabsco 4" Heavy Duty Flexmount Blower is a high-performance marine ventilation blower designed to provide reliable airflow in demanding onboard environments. Engineered for continuous-duty use, this blower is ideal for engine rooms, bilges, galleys, cabins, and enclosed compartments where efficient air circulation is critical for safety and comfort.
Built with marine-grade, corrosion-resistant materials, the Jabsco Flexmount blower delivers long-lasting durability in harsh saltwater conditions while maintaining quiet, efficient operation.
This 4-inch inline blower is designed to move large volumes of air efficiently, helping remove fumes, heat, moisture, and odors from enclosed spaces. It is especially well-suited for engine compartment ventilation, improving airflow and helping meet marine safety requirements.
The Flexmount construction reduces vibration and noise while allowing for easy installation in tight or irregular spaces. Its rugged housing and sealed motor ensure dependable performance even in high-humidity or corrosive environments.
Manufactured by Jabsco, a trusted leader in marine ventilation and pumping solutions, this blower features:
Corrosion-resistant housing
Ignition-protected design for marine safety
Long-life motor built for continuous operation
These features make it a dependable choice for both recreational and commercial marine applications.
While standard blowers are limited to 15-minute cycles, the 36770-0115 is built for 24/7 operation. This makes it the ideal choice for:
Equipment Cooling: Preventing overheating in electronics lockers or battery rooms.
The "Flexmount" design features a universal mounting bracket that allows the blower housing to rotate.7 This means you can mount the bracket to a flat bulkhead and then aim the discharge port in any direction (360°) to create the straightest, most efficient ducting path possible.8
Corrosion-Resistant: Constructed with a tough, reinforced thermoset plastic housing and corrosion-resistant materials throughout to withstand salt air.
Thermal Protection: The motor includes automatic thermal overload protection to prevent damage in the event of a blockage or overheating.
Quiet Efficiency: The radial leaf fan design provides high-volume airflow (250 CFM) with relatively low noise and vibration.

NOT IGNITION PROTECTED: This specific 115V AC blower is not ignition-protected. It must not be used to exhaust flammable vapors (like gasoline fumes) and should only be installed on diesel-powered vessels or in non-explosive industrial environments. For gasoline engine compartments, you must use Jabsco’s DC-powered ignition-protected models (e.g., the 35770 series).
Mounting Location: Install the blower in the highest part of the compartment to effectively exhaust heat, ensuring it is protected from direct spray or deck wash.
Ducting: Use 4-inch flexible ducting. Keep runs as short and straight as possible; every $90^\circ$ bend significantly reduces actual CFM.
Wiring: Always have AC electrical components installed by a qualified marine electrician. Use a minimum of 16 AWG wire for runs up to 50 feet.
