Q: What is an R20T filter?

R20T filter is a type of fuel filter, usually referring to an oil-water separator, mainly used in equipment such as construction machinery, ships, diesel engines, etc., to protect the engine system by filtering impurities and moisture in the fuel.
Main features and applications: This filter is commonly used in fuel systems of brands such as Parker Racor. The "R" in the model may represent the Racor series, "20" represents capacity or size class, and "T" may refer to specific variants or technical versions; It is suitable for scenarios such as loaders, excavators, and marine diesel engines, and can effectively separate moisture from fuel and intercept particulate impurities, ensuring efficient engine operation.

Q: What does the "T" mean?

In Racor fuel filters, the "T" in codes like R12T or R20T typically signifies a 10-micron filtration rating, indicating the size of particles the filter is designed to capture, with "S" often meaning 2-micron and "P" for 30-micron, ensuring effective water/dirt separation for engines. 

Here's a breakdown:

• T = 10 Micron:This is a common fine-filtration rating, good for removing smaller contaminants and water from diesel fuel.
• S = 2 Micron:A finer rating for higher protection against very small particles.
• P = 30 Micron:A coarser rating, often used as a pre-filter to catch larger debris and water. 

Q: When should I change my Racor filter?

The timing of replacing Racor filters should be comprehensively judged based on usage time, mileage, operating status, and environmental conditions. The regular replacement cycle is usually 500 hours or 10000 kilometers of operation, but in practical operation, priority should be given to operating parameters and abnormal signals.

When the following situations occur, the filter element needs to be replaced immediately: the differential pressure gauge (optional) shows a pressure difference of more than 6-10 inHg, the engine power significantly decreases, the system performance does not recover after changing the oil, the vehicle is stopped for a long time before first use, or the vehicle is frequently fueled with inferior fuel or driven in a dusty environment for a long time with high pollution risks.

Attention should be paid during maintenance operations: Racor Aqualoce II original filter element must be used, and before replacement, ensure that the engine is turned off and the pipeline is depressurized; The operation includes loosening the T-shaped handle to remove the top cover, injecting clean fuel, lubricating the O-ring seal, reinstalling it and manually tightening it (tools are prohibited), starting the engine to check for leaks; If equipped with a heater, ensure that the relay and fuse are functioning properly (such as using a 25A fuse for a 12V system).
