Melt-Blown Polypropylene Filter Cartridges

PARSWOOD melt-blown polypropylene filter cartridges provide depth filtration for suspended particles, sediment and rust in compatible liquids. Thermally bonded polypropylene fibres form a graded-density structure that captures particles through the cartridge depth, without added binders or adhesives.

Choose your sediment filter

The PARSWOOD melt-blown polypropylene range offers the following options:

• Nominal filtration grades: 1, 3, 5, 10, 25, 50, 75 and 100 µm.
• Outside diameters: nominal 2.5 inches (63 mm) or 4.53 inches (115 mm), with a 1.10-inch (28 mm) inside diameter.
• Lengths: 9.75, 9.87, 10, 20, 30 and 40 inches.
• End connections: DOE without end caps, DOE with PE gaskets, 222/Flat, 222/Fin, 226/Fin and 226/Flat.
• Seal options: no seal, silicone, EPDM, NBR or FKM, depending on configuration.
• Core options: coreless or polypropylene core.
• Surface options: smooth, deep groove, mini-groove or coarse.

The ordering table below lists the configurations currently offered for online purchase, with individual part numbers, prices, stock quantities and delivery estimates.

Our currently stocked standard DOE cartridges have a deep-groove surface, a nominal 2.5-inch outside diameter (63 mm), and a 1.10-inch inside diameter (28 mm). Selected 40-inch cartridges with a spring cap or Code 8 (222/Fin) connection are also listed.

9.75-inch and 10-inch cartridges are different lengths. Match the installed cartridge length, outside diameter, bore and end connection to your housing before ordering. Micron rating and length alone do not establish fit.

Selecting a micron rating

A lower micron number targets finer particles. Finer filtration may require more frequent cartridge changes when solids loading is high. Select the grade for your incoming liquid, flow requirements and the equipment being protected.

These are nominal depth-filtration grades, not absolute membrane ratings or sterilizing-grade claims. Retention depends on the test conditions and process liquid; do not treat the micron number as complete removal of every particle at that size.

Typical applications

• Sediment prefiltration for water-treatment and reverse-osmosis systems.
• Particulate filtration of compatible process water, coolants and plating solutions.
• Prefiltration in food, beverage and other industrial processes, subject to application and material qualification.

This polypropylene sediment medium is intended for particulate filtration. Do not select it for dissolved chlorine removal without a separate treatment stage designed for that purpose.

Construction and operating limits

• Filter media: Polypropylene.
• Construction: Thermally bonded fibres without added binders or adhesives.
• Maximum operating temperature: 65°C.
• Maximum differential pressure: 2.0 bar at 20°C.

Confirm the applicable limits for the selected configuration, liquid and housing. The differential-pressure limit is measured across the cartridge; it is not the housing's maximum working-pressure rating. Do not assume the maximum temperature and differential pressure can be applied simultaneously.

Stock and backorders

Available stock is shown beside each SKU. Out-of-stock cartridges and quantities exceeding available stock can be ordered online with estimated delivery of 4–8 weeks from order confirmation. We will notify you if the delivery estimate changes.

Replacement selection

For replacement matching, compare the original part number, dimensions, end connection, seal requirements and filtration performance. Brand name or micron rating alone does not establish interchangeability.
