PURETEC GRANULAR CARBON CARTRIDGE

Puretec GC051 Granular Carbon Water Filter Cartridge

The Puretec GC051 is a genuine granular activated carbon replacement cartridge designed to significantly reduce chlorine, unwanted taste, odour, volatile chemicals, pesticides and sediment from compatible water filtration systems.

Rather than using a solid carbon block, the GC051 directs water through a bed of granular activated carbon to maximise contact between the incoming water and the carbon media.

The cartridge uses the standard 2.5" × 10" format, Puretec currently lists a 5 micron post-filter rating, and the individual cartridge has a manufacturer-listed flow rate of up to 13 litres per minute.

Quick answer: the Puretec GC051 is a 2.5" × 10" granular activated carbon cartridge for compatible Puretec systems. It targets chlorine, unwanted taste, odour, volatile chemicals, pesticides and sediment, with a current Puretec-listed cartridge flow rate of 13 L/min. Puretec specifies the GC051 in systems including the TS100 and CT15, as well as selected compatible filter housings.

WHAT IT DOES

What Does the Puretec GC051 Reduce?

Chlorine

Granular activated carbon is designed to significantly reduce chlorine from compatible mains-water applications.

```

Taste & Odour

The GC051 targets unwanted taste and odour to improve the drinking-water characteristics of compatible systems.

Volatile Chemicals

Puretec specifically lists volatile chemical reduction among the treatment functions of the GC Series.

Pesticides

Puretec also identifies pesticide reduction as part of the GC051's activated-carbon treatment capability.

Sediment

The cartridge incorporates post-filtration to reduce carbon fines and suspended particulate material before water exits the cartridge.

General Carbon Treatment

The GC051 is designed for general-purpose carbon filtration in compatible drinking-water and filtration applications.

```
GRANULAR ACTIVATED CARBON

Designed for Maximum Water-to-Carbon Contact

The GC051 is constructed so water enters at one end of the cartridge and travels through the length of the granular activated carbon bed before exiting.

This arrangement is designed to maximise contact between the water and carbon media, supporting adsorption of chlorine and other manufacturer-specified substances.

Puretec also incorporates an expansion pad intended to minimise channelling or bypass through the carbon bed.

POST-FILTRATION

Reducing Carbon Fines Before Water Leaves the Cartridge

A post-filtration layer is positioned downstream of the granular carbon media.

This stage helps reduce carbon fines and other suspended particles before the treated water exits the cartridge.

Puretec's current online product specification lists the GC051 with a 5 micron post-filter rating.

Primary Treatment Chlorine, unwanted taste, odour, volatile chemicals, pesticides and sediment
Construction Feature Full-length carbon bed with expansion pad and downstream post-filtration
TS100 COMPATIBILITY

Puretec GC051 & the TS100 System

Puretec currently lists the GC051 as a genuine replacement cartridge for the TS100 dual under-sink drinking-water system.

Within the TS100, the GC051 provides the carbon-treatment stage alongside the system's separate sediment cartridge.

Do not confuse TS100 and TS200 replacement cartridges. The TS100 uses GC051 as its carbon stage, while the TS200 uses the finer CB951 carbon block cartridge.
CT15 COMPATIBILITY

Puretec GC051 & the CT15 Countertop Filter

Puretec also specifies the GC051 as the replacement cartridge for the CT15 countertop filtration system.

The complete CT15 has a manufacturer-listed flow range of up to 4 L/min. This is lower than the GC051 cartridge's individual 13 L/min rating because complete-system flow depends on the housing, connections and overall system design.

OTHER COMPATIBLE PURETEC HOUSINGS

Selected FP & TSI Applications

Puretec's replacement guides also list the GC051 as the mains-water taste-and-odour cartridge for selected standard 10-inch housings.

Selected FP Housings

Puretec lists GC051 for compatible FP10-series housings where a mains-water taste-and-odour cartridge is required.

```

Selected TSI Housings

Puretec lists GC051 as a taste-and-odour option for selected TSI 10-inch stainless filter housings.

Check the Exact Model

Cartridge dimensions alone do not confirm compatibility. Always check the replacement guide for the installed system or housing.

```
NOT UNIVERSAL

Check Compatibility Before Ordering

The GC051 uses a common 2.5" × 10" cartridge format, but it should not be described as universally compatible with every standard filter housing.

Different systems can require different filtration media, flow characteristics, micron ratings or cartridge configurations even where the physical dimensions look similar.

Confirm the replacement code where possible. If your current system specifies GC051, use the genuine GC051 replacement unless Puretec provides an approved alternative for that particular application.
GC051 VS CB951

Granular Carbon vs Fine Carbon Block Filtration

Feature GC051 CB951
Carbon Type Granular activated carbon Bonded carbon block
Size 2.5" × 10" 2.5" × 10"
Nominal / Post-Filter Rating 5 micron post-filter listing 0.5 micron nominal
Listed Flow 13 L/min 15 L/min
Chlorine, Taste & Odour Yes Yes
Specified Cyst Reduction Not the standard GC051 claim Yes

GC051 and CB951 should not be treated as interchangeable solely because both are standard 10-inch carbon cartridges.

SPECIALTY GC SERIES

Do You Need a Different GC Cartridge?

Puretec produces other GC Series cartridges for applications requiring treatment functions beyond the standard GC051 specification.

GC051

Standard granular-carbon cartridge for chlorine, taste, odour, chemical and sediment reduction.

```

GC201-H

A separate Puretec granular-carbon cartridge specified for applications requiring heavy-metal reduction.

GC051-SL

A separate slimline granular-carbon cartridge that includes scale-control treatment.

```
Do not apply specialty-cartridge claims to the standard GC051. Heavy-metal or dedicated scale-control performance belongs to specific Puretec models designed for those treatment requirements.
WHEN TO REPLACE

How Often Should the GC051 Be Replaced?

Replacement timing depends on the filtration system in which the GC051 is installed.

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

  • Applicable 6–12 month service interval has been reached
  • Chlorine taste begins to return
  • Unwanted odour becomes noticeable
  • Water flow has noticeably reduced
  • Incoming water quality has changed
  • Previous cartridge replacement date is unknown
WHY SERVICE LIFE VARIES

What Affects GC051 Cartridge Life?

Water Consumption

Higher water use moves a greater total volume through the granular activated carbon bed.

```

Chlorine & Chemical Loading

Higher incoming treatment demand can use the adsorption capacity of the carbon more quickly.

Sediment Levels

Suspended particulate material can contribute to restriction and influence practical cartridge life.

```
CARTRIDGE REPLACEMENT

What Is Involved in Replacing a GC051?

The GC051 is a conventional replacement cartridge installed inside a compatible reusable filter housing. It is not a sealed quick-twist cartridge.

  • Confirm the system specifies GC051
  • Isolate the incoming water supply
  • Relieve system pressure
  • Open the appropriate filter housing
  • Remove the used cartridge
  • Clean the accessible housing as required
  • Inspect the O-ring and sealing surfaces
  • Install the replacement GC051 correctly
  • Reassemble the filter housing
  • Restore water pressure gradually
  • Check the housing and connections for leaks
  • Flush the system according to the applicable Puretec instructions
WATER QUALITY CAUTION

Carbon Filtration Is Not Water Disinfection

The GC051 is designed for carbon filtration and particulate post-filtration. It should not be described as sterilising water or guaranteeing microbiological safety.

Where source water is microbiologically unsafe or of unknown quality, use the disinfection and treatment arrangement required for the complete system and water source.

DIY OR PROFESSIONAL SERVICE

Can the GC051 Be Replaced Yourself?

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

Always follow the instructions for the complete Puretec system or housing rather than relying only on the cartridge's physical dimensions.

Professional servicing may be appropriate where the system is leaking, difficult to access or cannot be safely isolated. Worn O-rings, damaged housings, valves, fittings or plumbing faults can require additional components or repair work.
