PURETEC POLYSPUN SEDIMENT CARTRIDGE

Puretec PX051 5 Micron Polyspun Sediment Cartridge

The Puretec PX051 is a genuine 5 micron sediment replacement cartridge designed to reduce dirt, rust, sand, silt, algae and other suspended particles from compatible water filtration systems.

Manufactured from virgin polypropylene, the PX051 uses Puretec's graded-density polyspun construction to provide depth filtration throughout the cartridge rather than relying only on the outside surface.

The cartridge uses a standard 2.5" × 10" format and has a manufacturer-listed individual flow rate of up to 28 litres per minute.

Quick answer: the Puretec PX051 is a 5 micron, 2.5" × 10" graded polyspun sediment cartridge. It is designed for sediment, dirt, rust, sand, silt and algae reduction and is listed by Puretec at up to 28 L/min. Puretec specifies the PX051 as the sediment stage in systems including the TS100 and TS200 and as a sediment option in selected FP and TSI housings.

WHAT IT DOES

What Does the Puretec PX051 Filter?

The PX051 is specifically a sediment-removal cartridge. It does not contain activated carbon and should not be confused with cartridges intended for chlorine, taste or odour treatment.

Dirt & Sediment

Designed to capture suspended particulate material from compatible incoming water supplies.

```

Rust

Helps reduce particulate rust carried through water lines before it reaches downstream filtration stages.

Sand & Silt

The graded-density structure captures common suspended sand and silt particles through the filter media.

Algae

Puretec also lists algae among the suspended particulate material targeted by the PX Series.

5 Micron Filtration

The PX051 has a nominal particulate filtration rating of 5 micron.

Sediment Only

For chlorine, taste or odour reduction, a compatible carbon cartridge is required as a separate filtration stage.

```
GRADED DEPTH FILTRATION

How the PX051 Polyspun Cartridge Works

Puretec manufactures the PX Series from virgin polypropylene that is spun and melted simultaneously to form a graded-density filtration structure.

This allows suspended particles to be captured through the depth of the filter media rather than being retained only on the outer surface.

Puretec also designs the PX cartridge without a centre core, avoiding a solid internal core that would otherwise occupy filtration area inside the cartridge.

SEDIMENT-ONLY FILTRATION

What the PX051 Does Not Do

The PX051 is designed for physical sediment filtration. It is not an activated-carbon, scale-control, reverse-osmosis or disinfection cartridge.

Do not rely on PX051 for chlorine or taste-and-odour treatment. Systems such as the Puretec TS100 and TS200 pair the PX051 with a separate carbon cartridge specifically because the two stages perform different filtration functions.

TS100 COMPATIBILITY

PX051 in the Puretec TS100

Puretec currently specifies the PX051 as stage one in the TS100 dual under-sink filtration system.

The PX051 removes sediment before water passes through the GC051 granular carbon cartridge in stage two.

Stage 1 – PX051

5 micron polyspun sediment filtration.

```

Stage 2 – GC051

Granular activated carbon treatment for chlorine, unwanted taste and odour.

```
TS200 COMPATIBILITY

PX051 in the Puretec TS200

The PX051 is also the first-stage sediment cartridge in the Puretec TS200.

In the TS200 it is followed by the finer CB951 0.5 micron carbon block cartridge.

Stage 1 – PX051

5 micron sediment treatment on the inlet side of the twin filtration system.

```

Stage 2 – CB951

0.5 micron carbon block treatment for chlorine, unwanted taste, odour, sediment and specified cyst reduction.

```
OTHER PURETEC APPLICATIONS

Selected FP & TSI Housing Compatibility

Puretec's current replacement guides also list the PX051 as the mains-water sediment cartridge for selected standard 10-inch housings.

FP10 Series

Puretec lists PX051 as a mains-water dirt, rust and sediment cartridge for selected FP10 housings including FP10M, FP10B, FP10C and FP100.

```

TSI Standard Housings

Puretec lists PX051 as a sediment option for selected standard TSI housings including TSI-151, TSI-201 and TSI-251 configurations.

Check the Exact System

Always confirm the cartridge code required by the installed Puretec system or housing before ordering.

```
NOT UNIVERSAL

Standard Size Does Not Mean Universal Compatibility

The PX051 uses a common 2.5" × 10" cartridge format, but that does not mean it is automatically the correct cartridge for every 10-inch water-filter housing.

Different systems can require a different micron rating, filtration media, cartridge length or treatment type.

Confirm the model before ordering. If the existing system specifies PX051, use that replacement unless Puretec provides another approved cartridge option for the particular application.
PX051 VS MC051

Sediment Filtration vs Moulded Carbon Filtration

The PX051 and MC051 are both 5 micron, 2.5" × 10" Puretec cartridges, but they perform different treatment functions.

WHEN TO REPLACE

How Often Should the PX051 Be Replaced?

Replacement frequency is determined by the complete filtration system in which the PX051 is installed and by incoming water conditions.

Puretec's TS Series and standard housing maintenance guides commonly specify cartridge replacement approximately every 6–12 months, depending on water quality and usage.

  • System's recommended service interval has been reached
  • Water flow has noticeably decreased
  • Sediment loading is visibly high
  • Incoming water contains increased dirt or rust
  • Water conditions have changed
  • Previous cartridge replacement date is unknown
WHY SERVICE LIFE VARIES

What Affects PX051 Cartridge Life?

Sediment Loading

Water containing more dirt, rust, sand or silt can load the cartridge more quickly.

```

Water Consumption

Higher usage passes a greater total volume through the filter media.

Incoming Water Conditions

Changes to source-water conditions can shorten or extend the practical service interval.

```
CARTRIDGE REPLACEMENT

What Is Involved in Replacing a PX051?

The PX051 is a conventional cartridge installed inside a compatible reusable filter housing. It is not a sealed quick-twist cartridge.

  • Confirm the installed system specifies PX051
  • Isolate the incoming water supply
  • Relieve pressure from the filtration system
  • Open the applicable filter housing
  • Remove the used sediment cartridge
  • Clean the accessible filter bowl as required
  • Inspect the housing O-ring and sealing surfaces
  • Install the new PX051 in the correct position
  • Reassemble the filter housing
  • Restore the water supply gradually
  • Check the housing and fittings for leaks
  • Flush or recommission the complete system according to its instructions
BEFORE ORDERING

Check These Details First

  • Existing cartridge code is PX051
  • Required nominal sediment rating is 5 micron
  • Required cartridge size is 2.5" × 10"
  • You require sediment filtration rather than carbon treatment
  • Existing filter housing is serviceable
  • System-specific cartridge order has been checked
  • Water can be safely isolated for maintenance
  • Other filtration stages have been identified where applicable
DIY OR PROFESSIONAL SERVICE

Can the PX051 Be Replaced Yourself?

Routine cartridge replacement may be practical where the complete filtration system is intended for owner servicing and can be safely isolated, depressurised and resealed.

If the PX051 forms part of a multi-stage system such as the TS100 or TS200, make sure it is returned to the correct sediment-stage position.

Professional servicing may be appropriate where access or condition is uncertain. Damaged O-rings, leaking housings, valves, tubing or other system components can require additional parts or repair work beyond the cartridge itself.
