Jyntrel Sintered Activated Carbon Block Filter Ф40×195 for Water Purifiers

This Jyntrel product is a sintered activated carbon block filter with a nominal outer diameter of Ф40 mm and a length of 195 mm, moulded from high-iodine coconut shell carbon with food-grade ion exchange resin built into the matrix. It filters chlorine and chloramine taste and odour, organic compounds, discolouration and heavy metals such as lead and mercury, while the resin fraction softens the water and reduces scale. It is intended for appliance and equipment builders, water treatment OEMs and brand owners who need a stable CTO-stage or T33-stage cartridge for reverse osmosis purifiers, dispensers, refrigerator water systems and commercial coffee machines.

Operating Conditions and Airflow Path

Although this stick is a liquid-phase cartridge, the design logic follows the same system discipline we apply to air filtration: define the path, the duty point and the environment before the media is fixed. Here the path runs from the supply line through the cartridge wall from outside to inside (or inside to outside depending on the housing), and the operating point is set by the feed pressure, the flow rate you draw and the pressure drop that the block presents at that flow.

Three conditions govern performance. First, flow and contact time: a higher flow through the same Ф40×195 block shortens the residence time in the carbon and resin, so an oversized pump on an undersized cartridge will pass chlorine earlier than the rated life suggests. Second, feed water quality: turbidity, hardness, iron and the chlorine load all consume capacity, and the ion exchange resin is affected by the hardness and regeneration history of the supply. Third, the mechanical environment: the sintered block is a rigid moulded body, but it should be supported in a housing that seals the end faces without imposing bending loads on the cylinder. In coffee and beverage equipment, the same cartridge sees hot or warm water and intermittent draw-off, which is a different duty cycle from a domestic reverse osmosis system running at low flow for long periods.

For air-side systems, the analogous questions are velocity, dust loading and pressure drop across the media; for liquid-side applications, they are flow, differential pressure and water chemistry. Our engineering team will map your duty point onto the cartridge geometry before confirming a specification.

Core Performance

The block uses 100% coconut shell activated carbon, selected for a high iodine number so that the micropore structure is well developed for chlorine, taste, odour and volatile organic compounds. Sintering binds the carbon into a uniform porous body with a fine, even pore distribution rather than a compressed granular fill, which gives a high initial flow and a stable differential pressure through life.

Filtration accuracy is fine enough to intercept particulate matter, and the moulded structure does not release loose carbon fines downstream — a point that matters where the cartridge sits ahead of a membrane or a beverage valve. The built-in food-grade ion exchange resin softens the water, reduces scaling potential and contributes to the reduction of heavy metals including lead and mercury. The carbon fraction carries the chlorine and organic load; the resin fraction carries the hardness and metal load; together they let one cartridge serve as a combined CTO and softening stage in space-constrained equipment.

Adsorption capacity is large relative to the compact Ф40×195 envelope, which supports a long service interval under typical municipal water conditions. As with any adsorption media, the actual interval depends on the feed water and the volume drawn, so we recommend setting the change-out point from your own water analysis rather than from a single fixed figure.

Selection and Customisation: the Data We Need

This cartridge is one point in a flexible size range. Standard reference dimensions include Ф60×130, Ф62×240, Ф37.5×75, Ф38×57, Ф40×195, Ф51×127, Ф32×126 and Ф32×106 mm, and the platform supports outer diameters from Ф30 to Ф60 mm. Length, diameter and the ratio between inner and outer diameter can be set to suit your housing, and end-cap welding can be configured to match your connection.

To select or customise a cartridge, send us:

• the device or appliance model and the housing or manifold it fits;
• the required outer diameter, inner diameter and length, or a drawing;
• the flow rate you draw and the feed pressure, plus any peak demand;
• the feed water analysis: chlorine or chloramine level, hardness, turbidity, iron and target contaminants;
• the operating temperature and whether the duty is continuous or intermittent;
• the annual or per-order quantity and your packaging requirements.

With those inputs we can confirm whether the Ф40×195 standard size meets the duty or whether a custom mould is the better route.

Parameters

Typical Applications

The Ф40×195 format suits equipment where a compact cylindrical cartridge sits in a moulded housing. In household reverse osmosis purifiers it is used as the CTO pre-filter ahead of the membrane or as the T33 post-filter for taste polishing; in direct drinking water dispensers it provides the combined chlorine, odour and hardness duty in a single stage. Built-in refrigerator water filters use the same construction where the housing envelope allows, and commercial coffee machines use it to protect boilers and valves from scale while improving the taste of the brew water.

Because sizing is flexible, the same media can be supplied in the other reference dimensions listed above for appliances with different housing volumes. If you are specifying a new platform, the earlier in the design cycle you share the housing drawing and duty point, the more of the standard range we can apply without tooling.

Manufacturing and Testing at Jyntrel

Jyntrel has more than 20 years of experience in filtration research and manufacturing, with continuous export to Europe, the United States, Japan and Korea for over two decades — a supply record that supports stable, repeatable delivery for programme customers. Multiple automated production lines give a monthly capacity of several million pieces, which is what allows standard sizes and OEM runs to be scheduled without long queues.

Production takes place in a 50,000 m² plant in Zhongshan, Guangdong, China, including six clean workshops totalling 20,000 m². Quality is controlled through IQC, IPQC and OQC across the whole process, and the in-house laboratory is accredited by CNAS (China National Accreditation Service for Conformity Assessment), so filtration efficiency, dust holding capacity and resistance test reports can be issued from our own facility. The plant holds ISO 9001, ISO 14001 and ISO 45001 certification and achieved IATF 16949 certification in 2024. Products meet REACH and RoHS requirements and compliance documents can be provided. OEM/ODM support covers dimensions, structure, media grade, end-cap material, logo and packaging, and we have developed more than 1,000 filtration solutions to date.
