High-Performance Diesel Filter Paper for Advanced Fuel Filtration

1. Product Overview

Our premium diesel filter paper is engineered to meet the rigorous demands of modern diesel engine fuel systems. Designed as a critical component in fuel filtration, this specialized filtration media effectively removes particulate contaminants, water, and other impurities from diesel fuel. By ensuring a clean fuel supply, our filter paper protects sensitive engine components such as injectors, pumps, and combustion chambers from premature wear and failure. Manufactured using advanced resin-impregnated cellulose and synthetic fiber blends, this product offers exceptional filtration efficiency, high dirt-holding capacity, and long service life. Whether for automotive, marine, agricultural, or industrial diesel engines, our filter paper guarantees reliable performance under extreme operating conditions.

2. Key Features

• High Filtration Efficiency: Achieves up to 99.5% removal of particles down to 2-5 microns, ensuring ISO 4406 cleanliness standards are met.
• Superior Water Separation: Hydrophobic treatment enables >95% water removal efficiency, preventing fuel system corrosion and microbial growth.
• Enhanced Dirt-Holding Capacity: Multi-layered gradient density structure traps more contaminants without restricting fuel flow.
• Thermal & Chemical Resistance: Stable up to 120°C (248°F) and resistant to diesel fuel additives, biodiesel blends (B20), and acidic byproducts.
• Low Flow Resistance: Optimized pore distribution maintains consistent fuel pressure for optimal engine performance.
• Long Service Life: Durable construction withstands cyclic pressure, vibration, and temperature fluctuations.

7. FAQ

Q: What is the typical shelf life of diesel filter paper?

A: When stored in a cool, dry environment (15-25°C, <60% RH) away from direct sunlight, our filter paper maintains full performance for 24 months from the date of manufacture.

Q: Can this filter paper be used with biodiesel blends?

A: Yes. Our media is formulated to resist swelling and degradation from B20 biodiesel. For higher blends (B30+), we recommend consulting our technical team for a custom formulation.

Q: How does your filter paper compare to standard cellulose-only media?

A: Our hybrid cellulose-synthetic media offers 40% higher dirt-holding capacity and 2x longer service life compared to standard cellulose, while maintaining lower pressure drop across the filter element.

Q: Do you provide samples for testing?

A: Yes. We offer free A4-sized samples for laboratory evaluation. For production-scale trials, we can supply 10-meter rolls at nominal cost. Contact us with your target specifications.

Q: What is the minimum order quantity (MOQ)?

A: Standard MOQ is 500 kg per specification. For first-time customers or custom formulations, we accept 200 kg trial orders to validate performance before scaling up.

Q: How is the filter paper packaged for export?

A: Media is wound on 3-inch ID cores, wrapped in moisture-proof polyethylene, and packed in reinforced cardboard boxes or wooden crates. Each roll is labeled with batch number, weight, and technical data.
