Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Fuel Filtration: Designed to remove contaminants (dirt, debris, water) from diesel fuel, ensuring clean fuel delivery to Caterpillar diesel engines.
  • Engine Protection: Prevents wear and damage to injectors and fuel pumps by maintaining optimal fuel purity, extending engine lifespan.

Key features

  • 1. Corrosion-Resistant Iron Casing

    • With a durable iron casing and layered filter paper, you can ensure long-lasting performance in harsh diesel engine environments, outlasting plastic-bodied filters by up to 30%*

  • 2. Universal Mounting Design

    • With a universal mounting system compatible with Caterpillar engines, you can achieve quick installation without specialized tools compared to custom-fit filters*

  • 3. High-Pressure Filtration Efficiency

    • With a 500-psi pressure tolerance and multi-layer filtration, you can maintain optimal fuel flow in heavy-duty trucks, filtering 98% of contaminants versus 85% in standard filters*

  • 4. Commercial-Grade Scenario Adaptability

    • Tailored for diesel generator use in industrial settings, you can ensure uninterrupted operation during prolonged runs, unlike residential-grade filters prone to clogging*

  • 5. EPR Germany Certified Sustainability

    • With EPR Germany certification for eco-friendly packaging, you can meet EU environmental regulations while reducing waste compared to non-compliant alternatives*
