Replacement parts for dust collector filter bags

If you’re looking for the best dust collector filter bag material, there are a few things to consider.

First, what kind of dust are you collecting?

Second, what’s the temperature inside your dust collector?

 And third, how often do you need to change the bags?

Here’s a quick rundown of some of the most popular materials for dust collector filter bags:

Polyester is a popular choice for general purpose dust collection, and can handle temperatures up to 200 degrees Fahrenheit.Polyester fabric is the most widely used material at normal temperatures and is the most cost effective option in many factories in low temperature environments.

Acrylic fiber filter bag features: It has good acid resistance, alkali resistance, heat shrinkage rate and hydrolysis stability. Excellent abrasion resistance, oil and fat resistance. Good heat setting performance.

PPS dust collector filter bag is widely used in carbon black, waste incineration flue gas purification and other industries. PPS has good heat resistance and stable size under the working temperature of 160-180 degrees Celsius.

Aramid(NOMEX) is an aromatic polyamide fiber with excellent heat resistance. It can work continuously at 204 degrees Celsius and has a maximum working temperature of 240 degrees Celsius. Nomex needle felt is widely used in metallurgy, chemical industry, building materials and other industries with poor working conditions due to its excellent heat resistance and high filtration efficiency.

PTFE dust collector filter bags are made of PTFE fiber, which has excellent heat resistance and chemical stability. It can be used in a wide temperature range from -180°C to +260°C. PTFE bag filters have good acid and alkali resistance and are suitable for filtration of strong acid and alkali. PTFE material has good hydrolysis resistance and is suitable for wet gas filtration. PTFE bag filters have good self-cleaning performance, which can reduce the frequency of filter bag replacement and maintenance, and improve production efficiency.

P84 polyimide filter bags have excellent performance on heat resistance, working temperature as high as 250-280 degree C/482~536F; P84 polyimide filter bags have good performance on anti-acid and anti-alkali, but not recommended to be used in strong oxidizing agent environment; P84 polyimide filter bags have excellent abrasion resistance, 3 times higher than that of the traditional fiberglass filter bag;

Fiberglass fabric is a very economical alternative to expensive PTFE, P84, NOMEX, PPS and other high temperature fabrics in many environments and performs equally well. It is usually 20-40% cheaper than PTFE, P84 and Nomex for the same size. So glass fibre is also an option for high temperature environments and can withstand temperatures of up to 260 degrees Celsius.

There are a few other things to keep in mind when choosing a dust collector filter bag material. Make sure the material is compatible with the type of dust you’re collecting, and check the maximum operating temperature to make sure it won’t be damaged by the heat inside your dust collector. Also, consider how often you’ll need to change the bags – some materials are more durable than others and can last longer before needing to be replaced.

Once you’ve considered all of these factors, you should have a good idea of which dust collector filter bag material is right for your needs.
