What is a nomex aramid filter bag?

The aramid filter bag is made of 100% polyester raw material. According to the characteristics of working conditions and usage requirements. Different production equipment and manufacturing procedures are adopted. A mixture of aramid fibers with different denier numbers through needle punching is made. Afterwards it undergoes from singeing, heat setting, and rolling to produce aramid felt with high filtration performance and efficiency. Then it is sewed to form a traditional aramid filter bag.

What are the special production processes for nomex aramid filter bags?

The aramid filter bag is made of aramid needle felt. The most traditional aramid needle punched felt on the market only requires needle punching, singeing, heat setting, and rolling before use. However, in complex working conditions with special and high filtration requirements, special production procedures are used to improve the performance of filter bags.

Filter bags can be treated with singeing, calendaring, water and oil repellent coating, PTFE impregnation and lamination as per customer’s demand and configuration.

Once you remove the filter bag from the filter housing, you can just take some measurements and pictures to send them to us. We would be able know your filter bag specifications using this method.

If you are able send us the samples, we can analyse the sample bag material and treatment.

We can make a sample for you to test its fitment with your bag house within a few days.

When you want to install a new filtration system and need some advice:

1. We will send you a configuration to fill it according to your specifications and conditions like temperature, chemical content and others. After you send it back to us .We will inform you about what kind filter bag is suitable for you.

2. Our engineers can arrange online meeting with your engineer or provide you with the configuration based on your demand.

What are the advantages of nomex aramid filter bags?

The biggest advantage of aramid dust removal filter bags is their good high-temperature resistance, wide temperature range, and generally can work continuously at around 240 ℃, with peak temperatures up to 260 ℃. Very suitable for dust collection systems in high-temperature environments.

Advantages of nomex aramid filter bags:

The biggest advantage of aramid dust removal filter bags is their good high-temperature resistance, wide temperature range. They can generally work continuously at around 240 ℃, with peak temperatures up to 260 ℃. Therefore making them highly suitable for filtration systems in high-temperature environments.

Good fire resistance and flame retardant ability: with a fiber oxygen index of 29, making the fibers difficult to burn. At a high temperature of 400 degrees, fibers slowly carbonize

Good chemical resistance: resistance to low concentrations of acids, alkali, hydrocarbons, and a small amount of cyanide.
