Absolute-rated filtration means the cartridge is designed to provide a defined level of particle retention at the specified micron rating, offering more predictable filtration performance than general nominal filtration. This makes the cartridge suitable for applications where consistent particle control and downstream cleanliness are important.

The correct micron rating depends on the particle size to be removed, required filtrate cleanliness, feed contamination level, flow rate, and allowable differential pressure. Available ratings range from 0.1 to 10 μm, allowing selection for fine filtration, polishing, and other precision liquid filtration duties.

PTFE filter media provides reliable particle retention together with good chemical stability, making it suitable for demanding food, beverage, and pure water filtration applications. Final suitability should still be confirmed according to the actual process fluid, temperature, chemical composition, and operating conditions.

The listed maximum operating temperature is 80°C, and the maximum differential pressure is 2.0 bar at 20°C. Actual allowable conditions should also consider the selected micron rating, process fluid, flow rate, and cartridge construction. Pressure and temperature should be evaluated together before final selection.

Compatibility should be checked according to cartridge outer diameter, length, sealing interface, and housing dimensions. The listed cartridge lengths are 20" and 40", with outer diameters of approximately 152–165 mm. Providing your current cartridge model or housing dimensions is the most reliable way to confirm fit.
