The Jyntrel Ф32×126 sintered activated carbon rod is a coconut-shell carbon block filter element with built-in food-grade ion exchange resin, supplied by Jyntrel for water purifier and refrigerator water circuits. It filters residual chlorine, odours, colour, and harmful heavy metals such as lead and mercury, while the resin fraction softens the water and helps limit scaling. It is intended for appliance and water-treatment manufacturers, OEM/ODM buyers, and brand owners who need a compact carbon block matched to a defined flow path and operating envelope.
In a water purifier or refrigerator water circuit, the carbon rod sits in the liquid path rather than in an air stream, so the governing conditions are water quality, flow rate, pressure drop, and the duty cycle of the appliance. The Ф32×126 format is a compact cartridge: water enters the outer surface, passes through the sintered carbon wall, and leaves through the core, contacting the carbon and resin throughout the traverse. Because the microporous structure is uniform, initial flow is high and the element holds a large saturation capacity before breakthrough.
The practical operating envelope in the available data is a conventional municipal supply: TDS below 500 ppm and residual chlorine below 2 ppm, with a recommended service life of 6–12 months or roughly 2,000–4,000 litres, depending on feed quality and working flow. Where a system runs at higher flow or a longer duty cycle, the element should be sized against the actual litres processed rather than nominal life alone. For OEM programmes, Jyntrel can run life testing against the target market's water conditions and issue a service-cycle recommendation, so the replacement interval in the appliance manual reflects the real installation rather than a generic figure.
The filtration medium is high-iodine-value coconut-shell activated carbon, sintered into a rigid rod with food-grade binder. The high iodine value indicates a well-developed micropore network, which is what drives adsorption of residual chlorine (bleaching powder), organic matter, VOCs, and taste and odour compounds. The sintered body is dimensionally stable and is described as not releasing black carbon fines downstream, a point that matters in potable-water circuits where fines can foul RO membranes or appear in dispensed water.
Food-grade ion exchange resin is incorporated in the rod. This adds softening action to limit scale deposition on downstream components and supports capture of harmful heavy metals including lead and mercury. Filtration accuracy is typically 5–10 microns. For a compact element in the Ф30–Ф60 outside-diameter family, the balance between wall thickness, carbon mass, and open core area determines both pressure drop and capacity, and the Ф32×126 size is aimed at appliances where installation space is limited. Jyntrel's CNAS-accredited laboratory can run flow, pressure-drop, capacity, particulate retention, TOC, and heavy-metal leaching tests, and can supply filtration performance reports with shipments.
Selection starts from the appliance, not the part number. To propose the right carbon rod, Jyntrel needs the device or vehicle model and the cavity or housing drawing, including the permitted outside diameter, inside diameter, and length, plus any end-cap welding requirement. Flow data matters as much as dimensions: state the working flow rate, the expected daily or annual litres treated, the inlet pressure, and the acceptable pressure drop across the element. Feed-water data (TDS, residual chlorine, hardness, and any target contaminants) defines whether the standard coconut carbon and resin blend is sufficient or whether a functional medium should be added.
Customisation is open across the range: outside diameters from Ф30 to Ф60, any length and inner/outer diameter ratio, end-cap welding, and OEM/ODM branding including logo printing, individual packaging, and colour-box and manual design. The Ф32×126 element is one standard size among references including Ф60×130, Ф62×240, Ф37.5×75, Ф38×57, Ф40×195, Ф51×127, and Ф32×106. Where a new housing demands a non-standard profile, tooling can be opened to the device requirement. Please share the operating data and quantity early so the proposal reflects the real duty.

Across these duties, the same engineering question applies: what flow, what feed water, and what pressure drop can the appliance tolerate? The answers determine the carbon mass and wall thickness, and therefore the service interval.
Jyntrel operates multiple automated production lines with monthly capacity in the millions of pieces, and has exported filtration products to Europe, the United States, Japan, and South Korea for more than 20 years, which supports stable, repeatable supply for appliance programmes. The production base covers 50,000 m², including 6 clean workshops totalling 20,000 m², where the sintered carbon rods are made in a controlled environment to avoid cross-contamination.
Quality control runs from IQC incoming inspection through IPQC in-process checks to OQC outgoing inspection on every batch. The in-house laboratory is accredited by CNAS and can issue reports on filtration efficiency, capacity, and resistance. The plant holds ISO 9001, ISO 14001, and ISO 45001 certification, and IATF 16949, obtained in 2024. Products meet REACH and RoHS requirements and compliance documents can be supplied. More than 1,000 filtration solutions have been developed to date, and OEM/ODM programmes can specify size, structure, media grade, end-cap format, logo, and packaging. The company is located in Zhongshan, Guangdong, China.
To receive a solution-oriented quote, send the device or vehicle model, the size or housing drawing, the working flow rate or daily litres, the operating conditions (TDS, residual chlorine, hardness, pressure, temperature), and the required quantity. If you are still in design, the target cavity dimensions and pressure-drop limit are enough to start. Contact the Jyntrel team with these details and we will propose the carbon rod format, medium, and packaging that fit your system.
For this carbon rod the governing data is water flow, not airflow: the working flow rate, expected daily or annual litres treated, inlet pressure, and acceptable pressure drop across the element. Feed-water TDS, residual chlorine, and hardness complete the picture. With those figures Jyntrel can size the carbon mass and wall thickness and recommend a service interval.
The Ф32×126 element is a water filter, not an air filter, so air velocity does not apply. In water circuits the relevant limit is flow and pressure drop: at higher working flow the element reaches its rated litres sooner. Size the rod against actual litres processed rather than nominal life.
Filtration accuracy is typically 5–10 microns, and the high-iodine coconut carbon adsorbs residual chlorine, organic matter, VOCs, and taste and odour compounds. The built-in ion exchange resin softens the water and supports capture of lead and mercury. Jyntrel's CNAS-accredited laboratory can provide filtration performance test reports.
Yes. Outside diameters from Ф30 to Ф60 are supported, with length and inner/outer diameter ratio made to the device requirement, plus end-cap welding and OEM/ODM branding such as logo printing and packaging. Share the housing drawing and the target cavity dimensions so tooling can be confirmed.
Send the device model, size or drawing, flow data, and quantity, and Jyntrel will propose the format and medium and prepare a quotation. Sample and tooling arrangements are confirmed against the specific configuration and order volume. The standard reference sizes, including Ф32×126, give a starting point for evaluation.
Standard sizes typically start at 1,000–2,000 pieces, while custom configurations are recommended from 5,000 pieces; the exact figure depends on size and packaging. Standard stock can ship in 7–15 days, and OEM production runs generally take 25–35 days from the Zhongshan plant.
In conventional municipal water with TDS below 500 ppm and residual chlorine below 2 ppm, the recommended life is 6–12 months or roughly 2,000–4,000 litres. Commercial coffee machines and ice makers running at high duty should be changed by litres processed. Jyntrel can test against your target market's water to confirm a cycle.
Send the device or vehicle model, the size or drawing, the working flow rate or water flow, the operating conditions, and the quantity. If you are still in design, the target cavity dimensions and pressure-drop limit are enough. <a href="/en/contact">Contact Jyntrel</a> and we will respond with a proposal.
