Q: What is the difference between R90T and R90P? 

R90T and R90P are two diesel fuel filter models from the Racor series, a division of Parker in the United States. They are primarily used for fuel water separation and diesel pre-filtration, and are commonly found in diesel engine systems such as Cummins, Weichai, Mercedes-Benz, and Volvo.

• Different filtration accuracy:

R90T: Typically featuring a filtration accuracy of 10 micrometers (μm), it is suitable for high-end electronically controlled diesel engines (such as those compliant with China IV/China V or higher standards).
R90P: Typically featuring a filtration accuracy of 30 micrometers (μm), it is commonly used in scenarios with slightly lower filtration requirements, such as the China III emission standard or construction machinery.

• Different types of compatible engines:
R90T: Applicable to high-end electronically controlled diesel engines with a displacement of 3–7 liters, such as Cummins ISF, Weichai WP10/12, etc.
R90P: It is more commonly found in National III EGR engines or heavy-duty construction machinery, such as certain Foton and Dongfeng Cummins models.

• Structural and functional differences:

Some R90T models (such as R90T-PHC-B1) come with a water level sensor cable interface and support intelligent alarm functionality.
The R90P mostly adopts a standard fuel water separation structure, and some models are equipped with a sedimentation cup for easy manual drainage.

• Similar but not exactly identical physical dimensions:
R90T: The diameter is approximately 108mm, and the height is approximately 158–160mm.
R90P: With a diameter of 108mm and a height of 220mm, it is noticeably taller and boasts a larger internal volume, making it more suitable for high-flow or high-impurity environments.

Compatibility description

The two cannot be directly interchanged, as they share the same thread specification of 1"-14 UNF, but differ in height, filtration accuracy, and compatible engines. Selection should be made according to the original manufacturer's recommendations.

Typical application scenarios
• R90T: urban buses, heavy-duty trucks meeting China IV emission standards or above, and high-end imported trucks (such as Mercedes-Benz and Volvo).
• R90P: construction machinery, mining vehicles, Euro III trucks, port machinery, etc.

Q: What micron is the R90T? 

 10-micron

Q: How does it work?

PARKER R90T is a diesel filter (coarse filter) primarily used to separate water and impurities from diesel, protecting the engine fuel system. Its working principle is based on physical filtration and fuel water separation technology.

• Filtering mechanism:
After entering the filter element, diesel passes through a high-precision pleated glass fiber filter material, which intercepts impurities such as solid particles, rust, and colloids in the fuel.

• Fuel water separation:
Utilizing coalescence and separation technology, tiny water droplets gather on the surface of the filter material into larger droplets, which then sink to the bottom of the filter bowl under gravity, achieving fuel water separation. Some models (such as R90T-PHC-B1) are also equipped with a water level sensing line interface, which can be connected to a sensor for alarm and prompt drainage.

• Structural characteristics:
o Adopting a rotary design, it is convenient for replacement and maintenance 10.
The pleated structure of the filter element increases the filtration area (approximately 45 cm²), enhancing both flux and lifespan.
With an applicable flow rate of 341 L/h, it meets the needs of high-displacement diesel engines.
