Q: What does 'PM' stand for?

The "PM" in Racor fuel filters represents filtration accuracy, specifically referring to the diameter of particulate matter that the filter element can filter out, measured in micrometers (μ m). For example, PM30 indicates that the filtration accuracy of the filter element is 30 microns, which can effectively intercept impurities with a diameter greater than 30 microns. ‌
In the fuel system, filtration accuracy is a key indicator for measuring filter performance, and high-precision filtration can protect the engine from particulate matter wear. Racor brand fuel filters are commonly used in equipment such as ships and generators, and their "PM" label is directly associated with the separation efficiency of the filter element. ‌

Q: How does a racor fuel filter work?

The working principle of the Racor fuel filter primarily relies on multi-stage filtration and separation technology to effectively remove particulate impurities and moisture from the fuel, thereby protecting the engine's fuel system. Its core mechanisms include physical filtration and selective permeation, ensuring fuel cleanliness.

• Filter Medium Characteristics: The filter element is made of special materials that are hydrophilic to oil but hydrophobic to water, allowing fuel to pass through while blocking moisture. Additionally, the metal mesh at the bottom intercepts solid impurities, achieving oil-water separation and particle filtration.
• Multi-stage filtration process: In operation mode, the fuel first passes through a pre-filter to remove large particle contaminants, then enters a fine filter element (such as Aquabloc media), where it captures tiny particles and residual moisture to prevent damage to the fuel injection system.
• Design Optimization: Some models (e.g., Racor 700 series) incorporate pump components to simplify maintenance and startup processes, reducing the risk of air entering the pipeline. Filters are typically installed in hard-to-reach locations but designed for easy replacement and maintenance.

• Materials and Safety: The filter element material is compatible with ultra-low sulfur diesel and biofuels (e.g., B20), and static-dissipating carbon powder is added during manufacturing to prevent static charge accumulation, enhancing safety in use.
• Maintenance Convenience: Some models feature an upper-disassembly design, allowing residual oil to be drained through an automatic oil discharge valve when replacing the filter element, reducing oil contamination and environmental pollution.
This design ensures the efficient and reliable operation of the fuel system, particularly suitable for diesel engines.
