Fuel Tank Vent Filters in marine fuel systems prevent contaminants and moisture from entering fuel tanks during ventilation. They ensure clean airflow while maintaining proper tank pressure to avoid vacuum or overpressure. These filters enhance fuel quality and protect engine performance in marine environments.

Size: Typically ranges from 1/2" to 2" in diameter, with lengths varying based on application.

Grade: Available in various grades such as 5 micron, 10 micron, and 20 micron for particulate filtration.

Viscosity: Compatible with fuels ranging from low viscosity (e.g., gasoline) to high viscosity (e.g., heavy fuel oil).

Buoyancy: Designed to prevent fuel spillage while allowing air passage; some models include buoyant elements for marine use.

Material: Constructed from corrosion-resistant materials like stainless steel, aluminum, or high-grade plastics (e.g., PTFE, polypropylene).

Operating Pressure: Typically rated for 3-10 psi, depending on design and application.

Temperature Range: -40°C to +120°C (-40°F to +248°F) for standard models.

Flow Rate: Varies by size, typically 5-30 CFM (cubic feet per minute).

Compatibility: Suitable for diesel, gasoline, biodiesel, and other marine fuels.

Standards Compliance: Meets ISO, SOLAS, and IMO regulations for marine fuel systems.

Fuel Tank Vent Filters and Marine Fuel Systems may comply with maritime standards such as ISO 10088, USCG regulations, or IMO guidelines, depending on the specific product and manufacturer. Always verify with the supplier for exact certifications.
