PURETEC MOULDED CARBON CARTRIDGE

Puretec MC051 5 Micron Moulded Carbon Cartridge

The Puretec MC051 is a genuine moulded carbon replacement cartridge designed to combine sediment filtration with chlorine, unwanted taste and odour reduction in a single standard-size cartridge.

Unlike a basic polypropylene sediment filter, the MC051 uses powdered activated carbon attached to a cellulose-free synthetic fibre matrix. This gives the cartridge both particulate-filtration and carbon-treatment capabilities.

The MC051 has a nominal 5 micron rating, measures 2.5" × 10" and has a manufacturer-listed flow rate of up to 16 litres per minute.

Quick answer: the Puretec MC051 is a 5 micron moulded carbon cartridge, not a sediment-only polypropylene filter. It is designed to reduce sediment, chlorine taste and odour, unwanted taste and odour and some organic chemicals. The cartridge uses the standard 2.5" × 10" format, is rated at up to 16 L/min and is used as stage one in the Puretec RO270 reverse osmosis system.

WHAT IT DOES

What Does the Puretec MC051 Reduce?

The MC051 combines the functions of a sediment cartridge and a carbon treatment cartridge in one filter.

Sediment

The nominal 5 micron filtration structure is designed to capture suspended particulate material.

```

Chlorine Taste & Odour

Activated carbon provides high chlorine taste-and-odour reduction compared with a sediment-only cartridge.

Some Organic Chemicals

Puretec also specifies the MC Series for reduction of some organic chemicals as water passes through the carbon media.

```
IMPORTANT CORRECTION

The MC051 Is Not a Basic Polypropylene Sediment Cartridge

The MC051 is sometimes confused with Puretec's PX051 because both are standard 2.5" × 10" cartridges with a nominal 5 micron rating.

They are different products. The PX051 is a graded polyspun sediment cartridge, while the MC051 is a moulded activated-carbon cartridge that combines sediment reduction with chlorine, taste and odour treatment.

Check the cartridge code before ordering. If your system specifies MC051, do not automatically substitute a PX051 simply because the physical size and nominal micron rating appear similar.
MOULDED CARBON TECHNOLOGY

Carbon & Sediment Filtration in One Cartridge

Puretec manufactures the MC Series using a modified moulded-block construction.

Powdered activated carbon is attached to a cellulose-free synthetic fibre matrix, forming a single filtration medium that combines the properties of a sediment filter with carbon treatment.

Puretec states that this construction provides low pressure drop through the service life of the cartridge and increased chlorine taste-and-odour and dirt-holding capacity compared with traditional carbon blocks.

CARBON FINES CONTROL

Designed to Prevent Carbon Fines Release

Puretec incorporates a fused post-filtration layer into the MC Series design.

This layer is designed to prevent carbon fines from being released into the filtered water stream during normal operation.

The result is a moulded cartridge that combines carbon treatment and sediment capture while avoiding the loose-media arrangement used by granular carbon cartridges.

RO270 COMPATIBILITY

Puretec MC051 & the RO270 System

Puretec currently specifies the MC051 as stage one in the RO270 reverse osmosis drinking-water system.

Within the RO270, the MC051 operates before the CB951 carbon block cartridge and reverse osmosis membrane.

Stage 1

MC051 – sediment and carbon pre-filtration.

```

Stage 2

CB951 – the next filtration stage within the current RO270 arrangement.

RO Membrane

RET1812-75 – the reverse osmosis membrane specified for the current RO270.

```
OTHER APPLICATIONS

Where Can the MC051 Be Used?

Puretec describes the MC Series as suitable for a range of residential, food-service, commercial and industrial filtration applications.

That does not mean the MC051 should be treated as universally compatible with every 10-inch filter housing or filtration system.

Confirm the cartridge specification before ordering. Check the replacement-cartridge code required by the existing Puretec system or confirm that the housing and application are specified for an MC051-compatible 2.5" × 10" cartridge.

MC SERIES OPTIONS

Other Puretec Moulded Carbon Cartridge Sizes

Puretec's MC Series includes several cartridge sizes and micron ratings for different filtration requirements.

MC051

5 micron, standard 2.5" × 10", listed flow rate 16 L/min.

```

MC052

5 micron, standard 2.5" × 20", listed flow rate 22 L/min.

MC05MP1

5 micron, 4.5" × 10" MaxiPlus cartridge with a larger physical format.

```

Different MC Series cartridges are not automatically interchangeable. Cartridge diameter, length, micron rating and system specification should all be checked.

WHEN TO REPLACE

How Often Should the MC051 Be Replaced?

Puretec provides a general replacement guide of approximately 6–12 months for standard filtration cartridges, with actual service life dependent on water quality and usage.

Where the MC051 is installed in the current Puretec RO270, Puretec specifies replacement of the applicable cartridges approximately every 6 months, depending on water quality and usage.

  • Applicable service interval has been reached
  • Chlorine taste or unwanted odour begins to return
  • Water flow has noticeably reduced
  • Cartridge has experienced high sediment loading
  • System manufacturer specifies replacement
  • Previous replacement date is unknown
WHY SERVICE LIFE VARIES

What Affects MC051 Cartridge Life?

Water Consumption

Greater water use moves a higher total volume through the activated carbon media.

```

Chlorine Loading

Higher incoming chlorine concentration places greater treatment demand on the carbon stage.

Sediment Loading

Greater particulate loading can increase restriction through the cartridge and affect practical service life.

```
CARTRIDGE REPLACEMENT

What Is Involved in Replacing an MC051?

The MC051 is a conventional cartridge installed inside a compatible reusable filter housing. It is not a sealed quick-twist cartridge.

  • Confirm the existing system requires MC051
  • Isolate the incoming water supply
  • Relieve pressure from the filtration system
  • Open the appropriate filter housing
  • Remove the used MC051 cartridge
  • Clean the accessible filter bowl as required
  • Inspect the housing O-ring and sealing surfaces
  • Install the new cartridge correctly
  • Reassemble the filter housing
  • Restore water pressure gradually
  • Check the housing and connections for leaks
  • Flush the system according to the applicable Puretec system instructions
DIY OR PROFESSIONAL SERVICE

Can the MC051 Be Replaced Yourself?

Routine replacement may be practical where the existing filtration system is designed for owner servicing and you can safely isolate the water, release pressure and correctly reseal the filter housing.

Always follow the instructions for the complete filtration system rather than relying on cartridge size alone.

Professional servicing may be appropriate where the system is difficult to access or isolate. Damaged seals, leaking housings, valves, tubing or other existing components may require additional work beyond a standard cartridge replacement.

FINAL CHECK

Is the Puretec MC051 the Right Cartridge for Your System?

The Puretec MC051 is a genuine 5 micron moulded carbon cartridge designed to combine sediment filtration with chlorine, unwanted taste and odour reduction in one standard-size filter.

It measures 2.5" × 10", has a manufacturer-listed flow rate of up to 16 L/min and is currently specified by Puretec as the stage-one replacement cartridge in the RO270 reverse osmosis system.

Before ordering, confirm that your existing system specifies the MC051. Do not substitute a sediment-only cartridge solely because the physical dimensions or micron rating are similar. Follow the maintenance requirements of the complete filtration system and check the housing for leaks after replacement.
