Key Features & Benefits
1. 115V AC Power Versatility
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.
2. Space-Efficient Design
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.
3. Built for Longevity
-
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.

Important Safety Note
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.
Pro-Tip for Installation:
"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."

-
Marine compartments and lockers

-
RV and camper ventilation
-
Light commercial and utility spaces
-
Shore power–connected vessels
