Pentair 155392-03 Semi Rigid Bag Filter 50 Micron Size 5

Product Description

The PENTAIR 155392-03 is a Size 5 semi-rigid polypropylene bag filter rated at 50 microns, designed for liquid filtration applications in industrial, commercial, and process systems. Measuring 4 inches in diameter and 18.5 inches in length with 1.75 square feet of filter area, this bag filter captures particulate matter at the 50-micron threshold. The semi-rigid construction maintains bag shape under flow, reducing collapse and ensuring consistent filtration efficiency throughout the service cycle. Licensed filtration technicians and industrial maintenance professionals typically specify this unit for high-flow housings that accept Size 5 bags.

This filter is suited for use in liquid process filtration systems where consistent particulate removal at 50 microns is required. Common applications include water treatment, chemical processing, and general industrial fluid filtration. The Size 5 form factor fits standard bag filter housings designed for that basket dimension. The polypropylene body material offers broad chemical compatibility, making it appropriate for mildly aggressive fluid streams as well as clean-water applications.

Installation Notes

Installation should be performed by a qualified filtration or industrial maintenance technician. Always depressurize and isolate the filter housing before removing the used bag. Confirm the housing basket is clean and free of debris before seating the new bag. Follow local industrial safety codes and the housing manufacturer's torque and seating procedures for the closure ring or lid.
