Tanvi DPTH filter cartridges are ideally suited for filtration of aggressive acids, bases & organic compound. The hydrophilic PTFE membrane has excellent chemical compatibility, wide-ranging thermal/pH resistance. These make the cartridge has a very good performance in chemical filtration at aggressive environment. With no need to pre-wet or flush pre-wetting, these hydrophilic cartridges are able to maintain filtration integrity, allow optical clarity when wet, reduce interference with biological processes, and maximize shelf-life.

Hydrophilic PVDF Membrane Filter Cartridge

Tanvi PFH series filter cartridges is particularly suited for the filtration of products containing elements that can adsorb to the media, such as preservatives and proteins. The very low binding nature of PVDF makes it a good choice for filtration of valuable protein solutions. It is absolute membrane filter cartridges and used for biological sterilization/clarification, and HPLC/analytical sample preparation. Tanvi PFH PVDF filter cartridges do not require the use of wetting agents, transmitting negligible extractables increase sample purity during sterilization or clarification procedures.

φ89 Capsule Filter

The large-diameter capsule filter is a disposable filter product equipped with a regular diameter 68mm pleated filter element. Filters are designed for final and pre-filtration in the pharmaceutical, biotechnology, microelectronics, and food and beverage industries. The larger diameter allows it to provide higher filtration flow while meeting the requirements of disposable filtration. Compared with ordinary capsule filters, it has a larger filtration area, larger filtration flow, and longer service life. And the clamp interface is easy to connect with other equipment. It can be used for sterile filtration of serum, tissue culture media, microbial growth media, and other viscous biological liquids in the pharmaceutical industry, as well as sterile tank venting. Also used in the filtration of metal and oxide CMP slurries, chemical rinses solutions, acids, bases, solvents, stripping solutions, deionized water, and storage tank vents in microelectronics manufacturing.

ACF Filter Cartridge

Activated Carbon Fiber Cartridges are designed to remove organic compounds, hydrocarbons, chlorine, color, and odors from aqueous and organic liquids and gases. The unique fibrous carbon media is designed for maximum flow and contaminant removal without the release of carbon fibers. The fibers allow for efficient contact time and adsorption capacity. ▶ Strong adsorption of chlorine, organics and odor; ▶ High dirt holding capacity and little carbon fiber release; ▶ No adhesives, binders, or surfactants are used in the manufacturing process; ▶ Depth filtration,high flow rate,durable and stable filtration effect; ▶ Manufactured in ISO class 8 clean room; ▶ Available in a range of lengths and connections to suit your individual purification and filtration needs.

Filter Bags

Monofilament multifilament filter bag It is a surface filter fabric structure, which is shaped at high temperatures to prevent the expansion of filter pores during the filtration process. Therefore, it has a filtration grade, captures impurities on the surface of its filter material, and the filter bag can be repeatedly cleaned and reused. Needle felt filter bag Using the principle of depth filtration, needle felt cloth filter bags can filter out a large amount of solid or gel soft impurities. 100% pure fiber is used to create a three-dimensional filter layer by acupuncture method. Larger particles of impurities are captured on the surface of the filter bag, while fine particles are captured in the deep layer of the filter material, so it is a depth filter material. Filtration accuracy from 1-200 m. Needle felt filter bag has the advantages of low cost, large filter area, and small pressure difference, and is the most economical filtration method. The surface of the needle-felt filter bag is specially treated to ensure that no fibers fall off, but the filter bag cannot be cleaned and reused. Melt blown non-woven filter bag A deep non-woven filter material composed of multiple layers of polypropylene microfibrils. The inner layer is composed of polypropylene needle felt cloth, which has a primary filtration function; the middle layer is composed of polypropylene microfibril melt-blown non-woven fabric, the filtration accuracy is from 1-200 m, and the filtration efficiency is 98%; the outer layer is composed of polypropylene Composed of spun-bond fibers, it has the advantages of high strength and no fiber shedding. Melt blown non-woven filter bag filtration accuracy: 1, 3, 5, 10, 25, 50, 100 m.

Depth Filter Modules

Features and Benefits Efficient filtration through high dirt holding capacity. Differentiated fiber and pore structure (internal surface area) for various applications and special process conditions. Reliable filtration effect through an ideal combination of the depth filter effect and the adsorptive potential. Maximum purity of raw material for minimum contamination on filtrate. Comprehensive quality assurance of all raw materials and additives.Intensive in-process control guarantees the consistent high quality of the final products.

Melt-blown filter cartridges

Melt-blown filter cartridges are made of polypropylene with the manufactural process: melting, spinning, drawing, receiving. Manufactural process lead pp fibers to interpenetrate and form winding path microporous structure.The fiber density along the direction of the filter diameter can be controlled, so the filter fiber density decreased from inside to outside. Features and Benefits ▶ All polypropylene construction ▶ Graded pore structure enhances dirt-holding capacity ▶ Unique proprietary process ▶ Easy and safe cartridge incineration and disposal ▶ No surfactants, binders, or adhesives ▶ Long service life and high dirt-holding capacity. ▶ Average pore size are widely optional ▶ Wide chemical compatibility

String Wound Filter Cartridges

String Wound Filter Cartridges are manufactured by computer modeling process which optimizes the filter cartridges geometrically and maximizes the use of cartridge surface area by the diamondshaped depth filtration cones. Enhanced graded density design offers high flow rate, low pressure drop and improved dirt holding capacity. Several filter media are available in Tanvi’s SW series, playing more effective and efficient solutions in different applications and processes. ▶ Continuous strand winding process provides consistent performances of high dirt holding capacity, long service and high flow rate. ▶ Numerous filter media provide excellent chemical compatibility for different applications. ▶ No odor, no foaming and no media migration. ▶ Computer programming capability optimizes the filter cartridge geometrically and maximizes the use of surface area.
