Zanxis sintered activated carbon block filter cartridge Ф60×130 is a coconut-shell carbon and food-grade ion-exchange resin filter element for water purifiers, refrigerators, and coffee machines. It reduces chlorine, taste and odour, colour, lead and mercury, and helps inhibit scale. It suits appliance makers and water-treatment brands that need documented, repeatable filtration performance.

Before approving a carbon block for a new appliance, specify the values that matter to your system. Confirm the inlet water quality, because chlorine load and turbidity affect cartridge life. Confirm the flow rate and pressure drop your appliance can tolerate; the micro-pore structure gives high initial flow, but the system curve must be checked. Confirm the required reduction targets for chlorine, taste and odour, colour, lead and mercury, and whether ion-exchange softening is needed. Confirm the dimensional envelope: OD, length, and ID/OD ratio, plus any end-cap welding or connection detail. Confirm the expected replacement interval in your duty cycle, typically measured in months under stated water conditions. Finally, confirm the compliance documents your market requires. Zanxis can supply CNAS-accredited test reports for efficiency, dust holding capacity, and resistance, plus REACH and RoHS compliance files, so each value is backed by a report rather than an assumption.
The cartridge is formed from high-iodine coconut-shell activated carbon and food-grade ion-exchange resin in a sintered block. The uniform micro-pore structure gives a high initial flow and fine filtration while holding the carbon together so the cartridge does not release black powder into the water. The ion-exchange resin softens the water and helps prevent scaling, while the carbon adsorbs chlorine, odours, colour, and volatile organic compounds, and captures heavy metals such as lead and mercury. Standard sizes range from Ф32×106 to Ф62×240, including the Ф60×130 size. Typical installations are household reverse-osmosis purifiers as a pre-filter (CTO) or post-filter (T33), direct-drinking water dispensers, built-in refrigerator water filters, and commercial coffee machines. Because dimensions can be customised, the same media can be supplied in the length, diameter, and end-cap format your appliance requires.
Zanxis operates a CNAS-accredited laboratory that issues test reports for filtration efficiency, dust holding capacity, and resistance, giving appliance makers citable data for design validation and market submissions. Production runs under ISO 9001, ISO 14001, and ISO 45001 systems, and the site holds IATF 16949 certification obtained in 2024. Quality control follows IQC, IPQC, and OQC stages, so incoming media, in-process blocks, and outgoing cartridges are checked against the approved specification. The manufacturing base covers 50,000 m², including six clean rooms totalling 20,000 m², which supports stable output and controlled handling of drinking-water contact parts. Products meet REACH and RoHS requirements, and compliance files are available. With more than 20 years of filtration experience and exports to Europe, the United States, Japan, and South Korea, Zanxis supports OEM/ODM programmes covering size, structure, media grade, end caps, logo, and packaging, with more than 1,000 filtration solutions developed to date.
To receive samples and the relevant test reports, send your device or vehicle model, target size or drawing, required airflow or water flow, operating conditions, and quantity. Zanxis will confirm the suitable carbon block specification and the documentation package for your market. Contact us to start the sample validation.
Yes. Zanxis can provide CNAS-accredited test reports covering filtration efficiency, dust holding capacity, and resistance for the sintered activated carbon block. REACH and RoHS compliance files are also available. Share your target market and specification so the correct report package can be prepared.
Sample validation time depends on whether the size is standard or custom. Standard sizes such as Ф60×130 can be supplied quickly for bench fitting, while custom tooling and end-cap welding add development time. Zanxis confirms the schedule after reviewing your drawing and operating conditions. Plan your validation around your own appliance testing, because flow and pressure drop must be measured in your system.
The sintered carbon block is designed to reduce chlorine, taste and odour, colour, and heavy metals such as lead and mercury, and the ion-exchange resin helps soften the water. Efficiency values are stated in the CNAS-accredited test report for the specific construction and test conditions. Confirm the report against your required reduction targets before sign-off.
Yes. Zanxis supports OEM/ODM customisation of length, diameter, and ID/OD ratio, and can tool the cartridge to match your device. End-cap welding is available. Provide a drawing or target dimensions so the construction can be confirmed before sampling.
MOQ and lead time are confirmed per specification, because standard sizes and custom tooled parts follow different production routes. Zanxis reviews quantity, packaging, and end-cap requirements before quoting. Lead time is then stated in the quotation so you can plan inventory.
Replacement interval depends on inlet water quality and daily flow. The carbon block has a high adsorption capacity for long service life, but chlorine load and turbidity determine when capacity is exhausted. Confirm the interval through your own validation under the intended operating conditions.
Confirm inlet water quality, flow rate, pressure drop, operating pressure and temperature, and the required reduction targets. Also confirm the dimensional envelope and connection detail. These values let Zanxis match the carbon block and resin loading to your appliance.
Send your device or vehicle model, size or drawing, required water flow, operating conditions, and quantity through the <a href="/en/contact">contact page</a>. Zanxis will reply with a suitable specification, sample arrangement, and quotation. Include any market compliance requirements so the correct test reports are included.
