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.
Features and Benefits

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 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 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
▶ No odor, no foaming and no media migration.
▶ Computer programming capability optimizes the filter cartridge geometrically and
maximizes the use of surface area.
The titanium rod filter element has a very wide chemical compatibility, can be used for most liquid filtration, and has a good performance in dust filtration. Because of its high porosity and good strength, it is particularly excellent infiltration of rigid particles, so it is widely used in the decarbonization filtration of liquids. At the same time, because of the chemical properties of titanium, it is used in strong oxidizing liquids, various complex chemical liquids, steam, and other filtration systems. , very suitable for selection.
▶ Uniform structure, narrow pore size distribution, and high separation efficiency.
▶ High porosity, low filtration resistance, and high penetration efficiency.
▶ High-temperature resistance generally can be used normally in the wet state below 280 degrees.
▶ Good chemical stability, acid, and alkali corrosion resistance, and oxidation resistance.
▶ It is non-magnetic and non-toxic and has good compatibility with human tissue and blood, so it is widely used in the pharmaceutical industry, food industry, and water treatment industry.
▶ No particles fall off, do not cause secondary pollution of the original solution, and meet the requirements of food hygiene and pharmaceutical GMP.
▶ It has a strong anti-microbial ability and does not interact with microorganisms.
▶ It can be regenerated online, is easy to clean, and has a long service life (usually several times that of the membrane filter element).
The stainless steel powder sintered filter element is made of 304 or 316 stainless steel powder. Process is that stainless steel powder is hydrostatic molded, and then sintered in high temperature vacuum. They can provide micron-level precision filtration, separate liquid, solid particles in the gas impurities. The filter elements can be cleaned by backwashing or back flushing, so that the filter element can be reused. They are high strength, chemical resistance, high temperature resistance and the applications are broad.
