Jabsco 4" 250 CFM Flexmount Blower - 12V

The Jabsco 4" 250 CFM Flexmount Blower – 12V is a DC-powered ventilation system engineered for marine cabin air circulation and bilge ventilation. With 250 cubic feet per minute (CFM) of high-volume airflow and a reinforced plastic housing built to resist marine corrosion, this flexmount blower delivers efficient, low-current operation in demanding saltwater environments where standard ventilation systems fail.

The universal flexmount bracket is a key design feature—it permits the 4-inch outlet to face any direction without requiring multiple unit variants, simplifying installation across different cabin layouts and hull configurations. Slip-on inlet ducting connections reduce fitting complexity, while corrosion-resistant materials throughout the assembly ensure durability in saltwater conditions where moisture and salt air accelerate degradation. This 12V blower meets USCG regulations 183.410 and ISO 8846 marine ignition protection standards, plus ISO 9097 marine variations compliance, making it a code-approved choice for both commercial and private vessel applications.

Weekend fishermen rely on blowers like this for cabin comfort during idle periods, while offshore and liveaboard boaters depend on them for consistent bilge ventilation and cabin air exchange in confined spaces. The low-current draw specification is particularly valuable on vessels with battery capacity constraints or solar-charged power systems. N.M.M.A type acceptance confirms this unit meets the marine industry's performance and safety benchmarks, making it a recognized solution among dealers and marine surveyors for retrofit installations and new-build specifications.
