What is an Acrylic filter bag?

Acrylic filter bag chemically named {Acrylonitrile} is made from acrylic needle punched felt that is produced by using needle punching method. Acrylonitrile fiber is produced using different production equipment and manufacturing procedures according to the characteristics of working conditions and usage requirements. After special hydrophobic treatment, it is singed, heat set, and rolled to produce acrylic needle felt with high filtration performance and efficiency. Afterwards, it is sewed to form a traditional acrylic filter bag with acrylic needle felt.

What are the special production processes for Acrylic filter bags?

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

How to check what kinds of filter bag is suitable for the bag house?

When old filter bag requires replacement:

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 Acrylic filter bags?

In low-temperature working conditions, acrylic filter bags have better resistance to chemical corrosion and moisture than polyester filter bags. Making them a good choice to replace polyester filter bags in certain special low-temperature environments.

Acrylic filter bags have the following characteristics:

1. High temperature resistance:

Acrylic fibers have high temperature resistance and can be used for a long time in high-temperature environments without melting or deformation.

2. Excellent chemical resistance:

Acrylic fibers have good corrosion resistance to chemicals such as acids and alkali, which can avoid damage to filter bags caused by chemicals. Hence, increasing the service life.

3. Excellent wear and tear resistance:

Acrylic fibers have excellent wear and tear resistance and can be used for a long time under the impact of high-speed airflow without any wear and tear .Insuring high performance over longer period of time.

4. Good breathing ability:

Acrylic filter bags have good breathing ability and can effectively filter dust particles.

5. Good re-use ability:

After cleaning and processing, PPS filter bags can be reused, thereby reducing usage costs and environmental pollution.
