Depth Filter Sheets for Challenging Filtration in Pharmaceutical, Food, Bioengineering, Chemical, and Other Industries
Carbflex Depth Filter Sheets combine high-performance activated carbon with cellulose fibers and are widely used in pharmaceutical, food, and bioengineering industries. Compared to traditional powdered activated carbon (PAC), Carbflex is more efficient at removing color, odor, and endotoxins while reducing dust generation and cleaning efforts. By integrating activated carbon with fiber materials, it eliminates the issue of carbon particle shedding, ensuring a more reliable adsorption process.
To meet diverse needs, Carbflex offers filter media in various removal ratings and configurations. This not only standardizes carbon treatment but also simplifies operation and handling, allowing users to select the most suitable product according to their specific requirements.

6. Long Service Life: Decreases replacement frequency and lowers operational costs.
The remarkable advantage of Carbflex ™ Depth Filter Sheets stems from the highly porous structure of the activated carbon used. With pore sizes ranging from tiny fissures to molecular dimensions, this structure offers an extensive surface area, enabling effective adsorption of colors, odors, and other organic contaminants. As fluids pass through the filter sheets, contaminants physically bond with the internal surfaces of the activated carbon, which has a strong affinity for organic molecules.
The efficiency of the adsorption process is closely linked to the contact time between the product and the adsorbent. Therefore, adsorption performance can be optimized by adjusting the filtration speed. Slower filtration rates and extended contact times help fully utilize the adsorption capacity of the activated carbon, achieving optimal purification results.We offer various models of activated carbon, each activated through different methods, resulting in differing adsorption capacities and characteristics. Additionally, different models of filter sheets and processes are available. We can provide customized filtration solutions and filter sheet services to meet your specific process requirements. For details, please contact the Great Wall sales team.
Product Range & Available Sheet Formats
Carbflex depth activated carbon filter sheets offer various filtration grades designed to handle products with different viscosities and characteristics.We categorize different types of products into specific grades to simplify the selection process of Carbflex ™ filter sheets.
We can produce filter sheets in any size and cut according to customer requirements, such as round, square, and other special shapes, to fit different types of filtration equipment and process needs. These filter sheets are compatible with various filtration systems, including filter presses and closed filtration systems.
In addition, the Carbflex ™ Series is available in modular cartridges suitable for use in closed module housings, catering to applications with higher demands for sterility and safety. For more information, please contact the Great Wall sales team.
Characterization
| Products | Thickness(mm) | Gram weight (g/m²) | Tightness (g/cm³) | Wet strength (kPa) | Filtering rate (min/50ml) | |
| CBF945 | 3.6-4.2 | 0.26-0.31 | ≥ 130 | 1'-5' | ||
| CBF967 | 5.2-6.0 | 1450-1600 | 0.25-0.30 | ≥ 80 | 5'-15' | |
Moistened Carbflex™ Depth Activated Carbon Filter Sheets can be sanitized with hot water or saturated steam up to a maximum temperature of 250°F (121°C). During this process, the filter press should be slightly loosened. Ensure thorough sterilization of the entire filtration system. Apply final pressure only after the filter pack has cooled down.
| Parameter | Requirement |
| Flow Rate | At least equal to the flow rate during filtration |
| Water Quality | Purified water |
| Temperature | 85°C (185°F) |
| Duration | Maintain for 30 minutes after all valves reach 85°C (185°F) |
| Pressure | Maintain at least 0.5 bar (7.2 psi, 50 kPa) at the filter outlet |
Steam Sterilization
| Parameter | Requirement |
| Steam Quality | Steam must be free of foreign particles and impurities |
| Temperature (Max) | 121°C (250°F) (saturated steam) |
| Duration | Maintain for 20 minutes after steam escapes from all filter valves |
| Rinsing | After sterilization, rinse with 50 L/m² (1.23 gal/ft²) of purified water at 1.25 times the filtration flow rate |
For liquids in the food and beverage industry, a typical flux rate is 3 L/m2·min. Higher flux rates may be possible depending on the application. Since various factors can influence the adsorption process, we recommend conducting preliminary scale-down tests as a reliable method to determine filter performance. For additional operational guidelines, including pre-rinsing the filter sheets before use, please refer to the instructions we provide.
* Filter sheets are produced in a controlled environment to ensure high quality and reliability.
* Manufactured under an ISO 9001:2015 certified Quality Management System.
Please contact Great Wall for recommendations on your specific filtration process as results may vary by product, pre-filtration and filtration conditions.
