Parker MBA0.5M20 Meltblown Filter Cartridge 0.5 Micron

Product Description

The PARKER MBA0.5M20 is a thermally bonded meltblown polypropylene filter cartridge rated at 0.5 micron for high-precision sediment and particulate removal. Measuring 20 inches in length with a 2.5-inch outside diameter, it is constructed entirely from polypropylene — including the core, media, and outer shell — making it chemically compatible with a broad range of liquid process streams. Rated for a maximum operating temperature of 180 degrees F and a maximum flow rate of 10 GPM, this cartridge is suited for applications where fine filtration is required without media migration. Licensed plumbers, water treatment technicians, and industrial maintenance professionals install this cartridge in standard 20-inch single or multi-stage filter housings.

The MBA0.5M20 is designed for liquid filtration service in residential, light commercial, and industrial settings. Typical applications include point-of-entry water treatment, pre-filtration ahead of membrane systems such as reverse osmosis units, process water filtration, and chemical-compatible liquid handling lines. The 0.5 micron rating targets fine sediment, dirt, and suspended particulate that pass through coarser cartridges. The all-polypropylene construction makes it suitable for mildly acidic or alkaline liquid streams where fiber shedding or binder contamination is a concern.

Key Features

• 0.5 micron rating captures fine sediment, particulate, and dirt from liquid streams
• Thermally bonded meltblown construction eliminates adhesives or binders that can contaminate process fluids
• All-polypropylene construction — media, core, and shell — for broad chemical compatibility
• Rated to 180 degrees F maximum operating temperature
• Maximum flow rate of 10 GPM for standard housing applications
• 20-inch length with 2.5-inch outside diameter fits standard 20-inch filter housings

Compatibility

Designed as a direct replacement cartridge for standard 20-inch filter housings accepting a 2.5-inch outside diameter meltblown polypropylene cartridge; intended for use with liquid service applications only.

Installation Notes

Installation is performed by a licensed plumber or qualified water treatment technician. Shut off the supply line and depressurize the filter housing fully before removing the spent cartridge. Inspect the housing O-ring for wear or deformation before seating the new cartridge, and hand-tighten the housing sump only — do not use a filter wrench to overtighten. Reinstall per local plumbing code requirements and verify for leaks after returning the system to service.
