What Are The Types Of Dust Collector Filter Bags?

Having an effective and efficient dust collector filter bag is essential. A dust collector is used to improve the quality of the air released from commercial and industrial processes by collecting dust as well as other impurities from gas and air. The air is directed by employing vacuum suction into a range of ducts, which run vertically and horizontally from pick-up points at multiple or single plant processes.

This process helps capture impurities and dust into filter bags and the best way to Buy Dust Extractor Filter Bags is to first determine their usage. Dust collectors are designed in such a way that they capture the dust and this way, filter the air from dusty and particle-laden air. Once the air is cleaned, it is released from the clean air side of the collector into the atmosphere while the surface of the filter bags contains all the solid particles.

This means a filter bag surface has a clean side and a dirty side. The bags are automatically cleaned so that their surface becomes permeable and air can flow again. The cleaning can be done by either pushing the air or sucking it using fans and blowers. Dust Collector Filter Bags Suppliers make filter bags of different shapes, sizes, and materials. Different materials offer varying applications, which are mentioned below.

· Cotton – The filter bags made of cotton are generally used on shaker type collectors and general applications include woodworking applications, atmospheric air cleaning, rock and cement products, cleaning rooms, and usual application handling surrounding air. The flammability is high and the chemical resistance is poor. This type of filter bag is not recommended for conditions where oxidizing agents and mineral acids are present.

· Polyester – This material allows filter bags to possess impressive resistance to abrasion, chemicals, and dry heat degradation. Moreover, they offer exceptional dimensional stability and are amongst the most commonly used filter bags today. However, they should not be used where phenolic compounds, moist heat, and hydrolytic degradation are present.

· Polypropylene – This material is desirable in conditions where moisture and chemical attack other fibers. Polypropylene filter bags offer excellent resistance to almost all alkalis and acids as well as possess high strength. The smoothness of fibers offers good cake release as well as resistance to blinding. This fabric is suitable to filter both organic as well as mineral acids, and except potassium and sodium hydroxide above 200F, it boasts decent resistance to alkalis.

· Acrylic – The general applications of acrylic filter bags include dryers, primary or secondary smelting, electric furnace, and aluminum reduction. These offer satisfactory chemical resistance to almost all organic and mineral acids and are superior to polyesters and polyamides in this regard. However, their resistance to alkalis is below most fibers except organic protein fibers like wool and silk. Overall, these bags possess great acid resistance as well as high resistance to hydrolysis.

Investing in a good filter bag would make the air filtration process easier. Based on the requirement and budget of the industries, bags made of different materials can be used.
