What is a P84 filter bag?

Fiber shape:

Synthesized from biphthalic anhydride and p-phenylenediamine yellow, with a trilobal fiber cross-section. Under the premises of the same weight and linear density, such a structure greatly increases the surface area of the fiber. Which is more beneficial for intercepting dust particles and contaminants during the filtration process.

It is obtained from polyimide fiber by needle punching. Its characteristics are remarkable because of its fiber fineness.

P84 filter material:

P84 material is a composite fiber fabric product. It is mainly composed of polyethylene terephthalate (P84) and polyamide (PA). According to the characteristics of working conditions and usage requirements. Different production equipment and manufacturing procedures are adopted. Mixture of P84 fibers with different denier numbers through acupuncture is made .Afterwards it undergoes through singeing, heat setting, and rolling to produce aramid felt with high filtration performance. It is then sewed to form a traditional P84 filter bag with P84 felt.

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 P84 filter bags?

Advantages of P84 filter bags

(1) High strength: P84 dust filter bags have high strength and can withstand high temperatures, high pressures, and harsh environments .Ensuring efficient dust particles filtration and high performance as well as a long service.

(2) Flame retardant ability: P84 dust filter bags have good flame retardant ability so they can effectively prevent the occurrence of fires.

(3) High temperature resistance: P84 dust filter bag has good high temperature resistance and can withstand the dust particles and contaminants filtration process under high temperature conditions.

(4) Corrosion resistance: P84 dust filter bags have a good corrosion resistance and can effectively resist the invasion of corrosive substances on the filter bags.

What are the special production processes for P84 filter bags?

The P84 filter bag is made of P84 needle felt. The most traditional P84 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.
