50 Micron Pleated Coarse Sediment Filter 20" Big

$114.40

The 20" Big 50 Micron Pleated Coarse Sediment Filter is designed to remove large suspended solids, dirt, rust, sand, silt, and other coarse particulate matter from water supplies. Manufactured using durable pleated polypropylene filter media, this cartridge provides a large filtration surface area, high dirt-holding capacity, and excellent flow performance for high-volume water filtration applications.

The 20" Big 50 Micron Pleated Coarse Sediment Filter is designed to remove large suspended solids, dirt, rust, sand, silt, and other coarse particulate matter from water supplies. Manufactured using durable pleated polypropylene filter media, this cartridge provides a large filtration surface area, high dirt-holding capacity, and excellent flow performance for high-volume water filtration applications.

    • Premium pleated polypropylene filter media for coarse sediment removal.

    • 50 micron filtration rating for large particulate reduction.

    • High dirt-holding capacity for extended cartridge life.

    • Reduces sand, rust, dirt, silt, scale, and suspended solids.

    • Large surface area design provides high flow rates with low pressure drop.

    • Rigid pleated structure maintains filtration performance under pressure.

    • Standard 20" Big Blue (4.5") cartridge size.

    • Compatible with most standard 20" Big Blue filter housings.

    • Helps protect pumps, valves, carbon filters, membranes, and other downstream equipment.

    • Whole-house water filtration systems.

    • Bore water and rainwater filtration.

    • Pre-filtration before finer sediment and carbon filters.

    • Commercial and industrial water filtration.

    • Irrigation and agricultural water systems.

    • Protection of pumps, valves, plumbing, and water treatment equipment.

    • General coarse sediment removal applications.

    • Filter Type: Pleated Sediment Cartridge

    • Media: Pleated polypropylene

    • Size: 20" Big Blue (20" x 4.5")

    • Micron Rating: 50 micron

    • Function: Coarse sediment, dirt, rust, sand, silt, and suspended solids reduction

    • Temperature Range: 4°C to 45°C

    • Maximum Operating Pressure: 125 psi (862 kPa)

    • Housing Compatibility: Standard 20" Big Blue filter housings

  • Typical replacement interval: Every 6–12 months, depending on water quality, sediment levels, and water usage.

    Replace sooner if:

    • Water flow decreases noticeably.

    • Pressure drop increases across the filter.

    • The cartridge becomes heavily clogged or discoloured.

    • Sediment begins passing through the filtration system.

    • Filtration performance declines.

    Pleated polypropylene media may be rinsed and reused in some non-potable applications. Replace the cartridge when the media is damaged, permanently blocked, or no longer provides effective sediment reduction.

    Best Used With

    • A 20 micron or 5 micron sediment filter as a secondary stage for finer sediment removal.

    • Activated carbon filters for chlorine, taste, and odour reduction.

    • As the first stage of a multi-stage filtration system to maximise the life of downstream filter cartridges.

    Not Suitable For

    • Fine sediment removal below the 50 micron rating.

    • Chlorine, taste, or odour reduction.

    • Bacteria or virus removal.

    • Water softening or hardness reduction.

    • Dissolved chemical contaminant removal.
