The Zanxis Ф32×106 sintered activated carbon rod is a cylindrical filter element made from high-iodine-value coconut shell activated carbon and food-grade ion exchange resin, designed to reduce chlorine, odours, colour, scale-forming minerals and heavy metals such as lead and mercury in drinking water. It is used in household reverse osmosis systems (as a pre- or post-carbon filter), direct drinking dispensers, refrigerator water filters and commercial coffee machines. Zanxis manufactures this rod in Zhongshan, Guangdong, China, and supports custom outer diameters from Ф30 to Ф60 mm with a fully flexible moulding process.

| Quality certification systems | The company’s 20,000 m² production base is certified to ISO 9001 and IATF 16949. Filter materials meet strict drinking water safety and hygiene standards and are backed by quality control at a national-level CNAS testing centre. |
Before specifying the Ф32×106 rod, confirm the values that directly affect fit and performance. The standard outer diameter is 32 mm and the length is 106 mm; if your housing requires a different dimension, Zanxis can mould to your drawing. Confirm the inlet water quality and flow rate so that the carbon block’s adsorption capacity matches your expected replacement interval. The ion exchange resin contributes to scale reduction and heavy-metal interception, so confirm whether your application prioritises softening or chlorine removal. Also confirm the end-cap configuration and connection method: end-cap welding is available as a custom option. Finally, confirm the packaging and labelling requirements if you need retail-ready filters. Zanxis provides CNAS test reports covering filtration efficiency, dust holding capacity and resistance, so you can verify these parameters against your own acceptance criteria.
The Zanxis Ф32×106 rod is produced by a flexible moulding process that combines high-iodine-value coconut shell activated carbon with food-grade ion exchange resin. The carbon’s microporous structure provides a large surface area for adsorbing residual chlorine, organic compounds and odours, while the ion exchange resin helps soften water by reducing scale-forming minerals and assists in intercepting heavy metals such as lead and mercury. The sintered structure is uniform, giving a high initial flow and high filtration accuracy without releasing black powder. The rod is intended for use in household RO purifiers as a CTO pre-filter or T33 post-filter, in direct drinking water dispensers, in built-in refrigerator water filters and in commercial coffee machines. Zanxis supports custom outer diameters from Ф30 to Ф60 mm, and can produce non-standard lengths and inner/outer diameter ratios with tooling made to your equipment requirements. End-cap welding is available to match your housing. This product is not a stand-alone purifier; it is a replacement filter element and should be installed according to the equipment manufacturer’s instructions.
Zanxis operates a testing and quality system built around verifiable data. The company’s own laboratory is accredited by CNAS (China National Accreditation Service for Conformity Assessment) and can issue test reports covering filtration efficiency, dust holding capacity and resistance. These reports allow you to confirm performance values before placing an order. In production, Zanxis applies IQC, IPQC and OQC across the process: incoming materials are inspected, in-process parameters are monitored and finished goods are checked before shipment. The company holds ISO 9001, ISO 14001 and ISO 45001 certifications, and its production base was certified to IATF 16949 in 2024. Products comply with REACH and RoHS environmental regulations, and compliance documents can be provided. Manufacturing takes place in a 50,000 m² plant in Zhongshan, Guangdong, China, which includes six clean workshops totalling 20,000 m². With more than 20 years of filter development and manufacturing experience, Zanxis has developed over 1,000 filtration solutions and exports to Europe, the United States, Japan and South Korea. Multiple automated production lines support a monthly capacity of millions of pieces.
To receive samples and test reports for the Zanxis Ф32×106 sintered activated carbon rod, please send the following details: your device or vehicle model (if applicable), the required size or a drawing, the airflow or water flow rate, the operating conditions (inlet water quality, temperature, pressure), and the quantity you plan to order. This information helps Zanxis match the filter to your application and provide the most relevant test data. Submit your request through the contact page, and the team will respond with sample availability, lead time and pricing.
Yes. Zanxis operates a CNAS-accredited laboratory that can issue test reports covering filtration efficiency, dust holding capacity and resistance. These reports are available with samples so you can verify performance before ordering. Contact Zanxis with your specific parameter requirements to request the relevant reports.
Sample validation time depends on your test plan and the parameters you need to confirm. Zanxis typically provides standard-size samples such as Ф32×106 for bench testing, and the CNAS test reports are supplied with the samples. The overall timeline is agreed when you specify your verification criteria.
The MOQ for standard sizes is typically 1,000–2,000 pieces, depending on the specific size and packaging requirements. For custom sizes, the suggested MOQ is 5,000 pieces. Zanxis will confirm the exact MOQ based on your order details.
Standard stock items can ship within 7–15 days. For OEM custom orders, mass production lead time is generally 25–35 days. Zanxis manufactures in its own plant in Zhongshan, Guangdong, China, and can arrange scheduled deliveries for long-term customers.
Replacement interval depends on inlet water quality and daily water consumption. Under typical household conditions, the carbon rod’s service life is approximately 6–12 months. Zanxis recommends monitoring flow rate and taste/odour as indicators for replacement.
Yes. The carbon rod’s performance is tested at Zanxis’s CNAS-accredited laboratory, with reports covering filtration efficiency, dust holding capacity and resistance. These reports allow you to confirm the efficiency values for your application. Request the reports together with your sample.
Yes. Zanxis supports OEM/ODM customisation, including outer diameters from Ф30 to Ф60 mm, non-standard lengths, inner/outer diameter ratios and end-cap welding. Tooling can be made according to your equipment requirements. Provide a drawing or sample to start the customisation process.
