Wire Cages are professionally manufactured, constructed from galvanized or stainless steel and welded for structural stability.

Yuanchen manufactures a wide range dust collector filter cages to fit all baghouse makes and models. We can also manufacture uncommon and specialized cage designs as required.

Nomex Filter Fabric made aramid filter bags Features 1.Good temperature resistance. It can regularly work in the continuous 204℃, and can bear the instant temperature of 240℃. 2.Good stability. Under the 240 ℃, its heat shrinkage ratio is less than 1%. Nomex filter media has an excellent high temperature stability. 3. Excellent chemical resistance. It can work normally in the low concentration of acid , alkali and hydrocarbons even if in the small amount of the fluoride environment. 4.Good fire resistance. Nomex(aramid) filter media only start to carbonize from 400℃, which is neither easy to autoignition and combustion-supporting. With these good performances, Nomex(aramid) filter media is widely used in steel industry, carbon black industry, construction industry and power industry. And become the best selling high temperature resistance filter media

Needle felt is a kind of non-woven filter fabric specially used for dust collector filter bags. It is a major filter material for industrial air filtration and dust removal. The needle felt is made of randomly arranged fibers needle punched on the scrim fabric, after that the fibers are close-knitted to form a tortuous three-dimensional stereo-structure, which is different from the traditional woven filter cloth composed of warp and weft yarns. It makes dust particles adhere to the surface of the filter material and form an initial layer of dust ( Filter cake), with the remarkable characteristics of small pore size, high filtration efficiency and low air resistance, greater air permeability and excellent dust particle capture.

1. Excellent high temperature resistance: it can work continuously at 204 ℃, and the instantaneous working temperature can reach 240 ℃.  2. High dimensional stability: only 1% expansion rate at 230 ℃, with high temperature stability.  3. Fire resistance and flame retardancy: decomposition and carbonization begin at 400 ℃, the limit oxygen index (LOI) is 30, and it does not spontaneously ignite or support combustion.  4. Good chemical corrosion resistance: acid and alkali resistance, not easy to corrosion.

The chemical name of PPS is polyphenylene sulfide. It is a white material with excellent thermal stability. Although it will burn when it is placed in a flame, the combustion will stop immediately when the flame is removed. It will show a yellow-orange flame when it burns, and a trace of black will be generated. Soot does not fall off the burned material, and forms residual coke, showing low flame spread and smoke density. The limiting oxygen index is 34-35. The most commonly used fineness is: 2.2 dtex. Other finenesses are: 1.1 dtex 1.7 dtex 3.0 dtex and so on. The most commonly used lengths: 51mm and 60mm. The working temperature is 130～160℃, the short-term working temperature is 190℃, and the melting point is 285℃. In addition, the oxygen content of the fiber should be less than 8% during normal use. The higher the oxygen content, the use temperature should decrease accordingly.

Features and advantages of needle felt filter fabrics: 1) Needle filter felt makes the air filter bags has a high and stable dust collection efficiency. 2) The statical dust capture rate of needle felt filter cloth could up to 99.5% ~ 99.99%. 3) The porosity of needle filter felt is as high as 70% ~ 80%, which is 1.6 ~ 2.0 times of woven filter fabrics, it gets larger air permeability and lower air resistance.
