PBT provides a combination of thermal stability, mechanical strength, and chemical resistance for demanding industrial filtration. In this series, both the filter media and cage use PBT construction, supporting operation at temperatures up to 120°C while maintaining stable filtration performance under suitable process conditions.

These fluids are listed among the intended applications for the Extreme Temp Series. However, final compatibility should still be confirmed according to chemical concentration, operating temperature, contact time, pressure, and the complete cartridge and sealing configuration before use in the actual process.

The correct micron rating depends on the contaminant size, required downstream cleanliness, solids loading, flow rate, allowable differential pressure, and filtration stage. Available ratings range from 1 to 100 μm, allowing the cartridge to be used for both general prefiltration and finer particle-removal duties in chemical and solvent systems.

The listed maximum operating temperature is 120°C, and the maximum differential pressure is 3.0 bar at 20°C. Because allowable pressure can change as temperature increases, pressure and temperature should be evaluated together rather than independently when defining the actual operating conditions.

It is designed as a replacement solution for 3M HFR-type high flow applications, but dimensional compatibility should still be verified before installation. Key factors include cartridge length, outer diameter, sealing interface, flow direction, and housing dimensions. The listed lengths are 20", 40", and 60", with outer diameters of approximately 158–164 mm.
