What is a PPS filter bag?

The PPS filter bag is made of polyphenylene sulfide raw material. Polyphenylene sulfide is a high-performance thermoplastic. It is produced using different production equipment and manufacturing procedures based on the characteristics of working conditions and usage requirements. High functional organic polyphenylene sulfide fibers are mixed through needle punching .Afterwards they are subjected to singeing, heat setting, and rolling to produce PPS needle punched felt with high filtration performance. Then they are sewed to form a traditional PPS filter bag using PPS needle felt.

What are the special production processes for PPS filter bags?

The PPS filter bag is made of PPS needle felt. The most traditional PPS needle 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 can be 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.

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 PPS filter bags?

Advantages of PPS filter bags:

The biggest advantage of PPS made filter bags is that they can also resist corrosion in high-temperature working environments. PPS is another type of high-performance fiber filter bag among organic fibers. Which not only can withstand high temperatures but also has excellent corrosion resistance that other high-temperature fiber filter bags cannot compare. So PPS filter bags are commonly used in the coal-fired boiler industry and high-temperature flue gas purification systems.

Good high-temperature resistance: PPS filter bags have excellent high-temperature resistance, can withstand temperatures up to 190 ℃, and are suitable for harsh environments that have high temperature, high humidity, strong acids, and alkali.

Good corrosion resistance: PPS filter bags have excellent corrosion resistance and can withstand the erosion of various acids, alkali, and organic substances. They will not harden or age after long-term use.

High filtration efficiency: The surface of the PPS filter bag is flat, with excellent resistance to adhesion and wear. It can efficiently filter small particles and harmful gases, ensuring the hygiene and safety of the environment it is used in.

High mechanical strength: PPS filter bags have high mechanical and tensile strength achieving great wear resistance .Thereby, they are not easily damaged or deformed. They can maintain high filtering effect and service life in harsh working environments.

5. Good re-usability: After cleaning and processing, PPS filter bags can be reused, thereby reducing usage costs and environmental pollution.
