The Jabsco 3" Flangemount Blower is a compact, dependable 115-volt ventilation blower designed to provide consistent airflow in marine, RV, and light commercial applications. With a 100 CFM airflow rating, this blower efficiently circulates air to help remove heat, moisture, fumes, and odors from engine spaces, compartments, and enclosed areas.
Built with Jabsco’s proven ventilation technology, this flangemount blower offers long service life and reliable performance in demanding environments.
Rated at 100 cubic feet per minute, this blower provides steady air movement for smaller compartments and ventilation needs. It is ideal for applications where compact size and controlled airflow are required.
The flangemount design allows for stable mounting to bulkheads or flat surfaces, ensuring reduced vibration and long-term reliability. This mounting style makes the blower well-suited for permanent ventilation installations.
Operating on 115V AC power, this blower is compatible with shore power or onboard AC electrical systems, making it ideal for marina-connected vessels, RVs, and stationary marine applications.
Manufactured by Jabsco, this blower features corrosion-resistant materials and a rugged housing designed to withstand moisture, vibration, and harsh operating conditions commonly found in marine environments.
(1) Jabsco 3" Flangemount Blower: 115V AC unit with a corrosion-resistant housing.
(1) Integrated Mounting Flange: Pre-molded into the intake side of the housing.
(1) Wiring Lead: For connection to an AC power source.
(1) Instruction Sheet: Including mounting hole patterns and electrical safety data.
Unlike most marine blowers that run on battery power (12V/24V), this unit is designed for boats with active AC systems (Generators/Shore Power). It is an excellent choice for:
Galley Exhaust: Removing cooking odors and heat.
Head Ventilation: Constant moisture and odor extraction.
Electronic Cooling: Keeping rack-mounted navigation or audio equipment cool.
The 3-inch diameter makes this blower ideal for tight spaces where a 4-inch model is too bulky. Despite its smaller size, it still moves a respectable 100 CFM, which is more than enough for small compartments or focused cooling.
High-Impact Housing: The tough plastic housing is designed to withstand the vibration and salt-air exposure of a marine engine room or bilge area.
Low Amp Draw: Drawing only 0.5 Amps, this blower is highly efficient and won't put a significant strain on your AC circuit.

NOT IGNITION PROTECTED: Like most AC-powered blowers, the 34744-0000 is not ignition protected. It must not be used in areas where flammable gasoline vapors may be present. It is strictly for diesel engine rooms, galleys, heads, or general industrial ventilation.
"Because this blower uses AC voltage, ensure it is wired through a dedicated GFCI-protected circuit if installed in a damp environment like a head or bilge. To reduce noise, ensure the mounting surface is rigid; if mounting to a thin fiberglass bulkhead, adding a small rubber gasket between the flange and the wall can significantly cut down on vibration resonance throughout the boat."
