How to choose a dust collector filter bag?
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?

Which types of dust Collector filter bags?
Here’s a quick rundown of some of the most popular materials for dust collector filter bags:
Polyester
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
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
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)
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
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
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
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.

Why So Many Different Types of Dust Collector Bags?
There are many different types of dust collectors used in industrial processes, and their requirements for a collector bag will vary depending on what process they’re intended to handle. For example: steel foundries need high efficiency; chemical plants may require acid or alkali resistant materials such as Ryton® Felt / PPS – but even within industries there can be substantial differences between system configurations requiring unique solutions meeting needs accordingly.
Larger companies might be able to invest in expensive dust collector bags with a higher initial price, but this is only if they’re willing put up with lower efficiency on the front end. Smaller businesses require cheaper equipment that won’t break their budget – which typically means more compact or lighter-weight options when compared side by sides against larger models from other brands

Larges firms may opt for costly collectors utilizing advanced technology such as electric motors at first; however these can translate into greater energy costs over time so there needs+to consider whether it makes sense given your business goals before making a decision.
