The fabric filter bags are used as filter media. The bags are oval or round tubes made of woven or felted material. Depending upon the chemical and moisture content of the gas stream, temperature, and other conditions, bag may be made out of cotton, nylon, polyester, fiberglass, ptfe or other materials.
The bags are chosen by depending on the need, that which type of cleaning methods are to be used. The Woven Filter Bags are used for the cleaning methods like shaking, reverse air. The efficiency of the bag depends on the space between the individual fibers. It affects the strength and permeability of the bag.
The fiberglass woven filter bags are made up of glass fiber fabric. The chemical finish to the fiberglass fabric is the important aspect tp get the best result of the filter bags with respect to its performance. So to enhance the life and performance of the filtration media, some finishes are apply to the filtration media. It leads to good performance and durability of the fabric.
To get best quality of filter bags, the environment for the manufacturing must be completely controlled.
The fiberglass woven filter bags are mainly used in chemical, cement, steel, utility boilers, carbon black and ferro-alloy industries.
The PTFE Laminated Filter Bag have the efficiency of fine particles at high temperature. The filter bags have easy installation and running cost.
The ptfe material is laminated to the base material. It is designed to resist sticky and sub- micron particulates leads to high air flow.
