Polyamide fiber is commonly known as nylon (Nylon), the English name is Polyamide (PA), and its density is 1.15 g/cm3; it is a general term for thermoplastic resins containing repeating amide groups -[NHCO]– on the molecular backbone. Including aliphatic PA, aliphatic-aromatic PA and aromatic PA.

Polyester is one of the most economical low temp filter bag medias used in the dust collection industry because of its reliable performance in a broad range of applications and availability. This media is used in industries including food manufacturing, woodworking, metalworking, building products, and energy. Polyester is one option if you are continuously operating between ambient – 275 degrees Fahrenheit, and have less than 10% moisture.

Filter bag is the most important part in dust collector which influences the collection efficiency and working temperature.

Renewal of bags creates major cost in maintaining bag house, so the lifetime of bags are the main factor affecting the cost and working condition of bag-house.

There are three types: woven fabric dust bag, non-woven fabric bag and compound filter material.

Three shapes: round type, flat type and customized type

Filtering method: inner filtering & outer filtering

Nylon has excellent toughness, self-lubricity, wear resistance and chemical resistance.

Academic properties, gas permeability, and oil resi stance, non-toxic and easy to color, etc.

Advantages: Long-term use temperature: less than 80 °C of organic acids with different concentrations,Alkali or salt can cause the swelling, dissolution or hydrolysis of PA.

Polyester filter bags are widely used in food, medicine, petroleum, paint, coating, chemical industry, metallurgy, electronics, machinery, automobile, light industry and other fields.

Specific applications of dust filter bags in various working conditions:where will be the filter bag installed in each plant?

Scope of application for filter bagCement plant: crushing, grinding, coal grinding, material transportation, dedusting on the top of the warehouse, raw meal grinding, cement grinding, packaging.

Metallurgical plants: electric furnaces, blast furnaces, desulfurization furnaces, induction furnaces, casting, sandblasting, barrel furnaces.

Power plant: material conveyor, smoke (powder) dust treatment, fly ash storage.
