Product Description

Choose SFFILTECH's wholesale air filters for the following reasons.

What is aramid filter bag

Aramid filter bags utilize high-strength aramid fibers, known for their heat resistance and chemical durability. These industrial filtration components, integral to dust collectors and environmental equipment, excel in high-temperature filtration applications and flue gas treatment. Designed for industrial use, they contribute to efficient particle removal in diverse industrial applications. The aramid fiber's chemical resistance ensures longevity, making it a reliable choice for demanding environments. These filter bags play a crucial role in enhancing air quality, exemplifying exceptional filter media performance and embodying key features such as industrial strength, environmental protection, and versatility in combating pollutants.

Two factors effect the choice of filter bags

Temperature: As the main component of dust collector, it is very important whether selected filter bag adapt to the flue gas temperature. Such as, the heat resistance of filter material exceeds the flue gas temperature too much, which will cause the waste of high temperature filter material as well as big investment in equipment. If it is lower than that of flue gas, it is possible to cause the burning of bag. So how to select the filter material according to the flue gas temperature? It can be divided into the following according to the temperature: normal temperature filter material: below 130 degrees Celsius, medium temperature filter material 130~180, high temperature filter material 180~280.

Flue gas composition: It includes the content of dust, specific gravity, particle size, viscosity or not, the water content in the flue gas and other parameters. All of these decide the way of cleaning, filter bag material treatment,filtration velocity. Usually, if the dust is dense, sticky and light, we usually choose pulse bag house and pulse bag filter. In addition, the filtration velocity is control more than 1.2m /min, sometimes 1m /min. As well as, the Filter material treatment is generally membrane, water and oil repellent, anti - static, oriented anti adhesive treatment.

Dust Separation Procedure

Different dust separation procedures require different weights and air permeability values for filter media.

Rules:

- The more effective the cleaning process, the more compact and heavier the filter medium can be.

- The higher the emission control standards, the heavier the filter medium should be.

Topsa: If these factors are well considered in advance, running cost like electricity for the fan or pressured-air for the cleaning pulses can be saved later on in a great amount.
