High Temperature Filter Bags


Is your application operating at a high temperature over 275 degrees Fahrenheit? If so, there are many dust collector

Aramid




Aramid filter media is commonly used in asphalt plants and rock plants where there is high heat but are no chemical issues. You can typically distinguish an Aramid filter bag by its color. It is usually yellow and can have brown speckles which is caused by singeing.

Characteristics Rating Relative Cost $$$ Max Continuous Operating Temperature 400 Degrees F. Abrasion Good Energy Absorpsion Good Filtration Properties Excellent Moist Heat Good Alkaline Good Mineral Acids Fair Oxygen (15%+) Excellent

Pros Cons Provides great resistance to highly abrasive dust applications. Mineral oxides can cause deterioration or partial decomposition over time.

Applications Cement Cupolas High Temp Dryers

Fiberglass


Fiberglass

It is cost efficient when compared to similar high heat filter medias and is the most common choice for situations where heat is above 400 degrees Fahrenheit. Fiberglass can have a lot of variation in color, and depending on the application, can have different types of treatment (i.e. silicon, carbon).

Characteristic Rating Relative Cost $$$$ Max Continuous Operating Temperature 500 Degrees F. Abrasion Fair Energy Absorption Fair Filtration Properties Fair Moist Heat Excellent Alkaline Fair Mineral Acids Poor Oxygen (15%+) Excellent

Pros Cons Performs excellent in high temperature applications up to 500 Degrees Fahrenheit. Sensitive bag to cage fit. Has poor flex abrasion qualities and would require a cage with 20 vertical wires for minimum support.

Applications Power Plants Cement Kilns Carbon Black Reactors

PPS




Characteristic Rating Relative Cost $$$$$ Max Continuous Operating Temperature 375 Degrees F. Abrasion Good Energy Absorption Good Filtration Properties Good Moist Heat Good Alkaline Excellent Mineral Acids Excellent Oxygen (15%+) Poor

Pros Cons Excellent resistance to acids and alkaline Sensitive bag to cage fit.

Applications Asphalt Plants Cement Mills Incinerators

P84




Characteristic Rating Relative Cost $$$$$$ Max Continuous Operating Temperature 500 Degrees F. Abrasion Fair Energy Absorption Good Filtration Properties Excellent Moist Heat Good Alkaline Fair Mineral Acids Good Oxygen (15%+) Excellent

Pros Cons Excellent stability in applications with high dry heat temperatures, mineral acids, and alkaline. Must oversize bag for shrinkage that can occur in temperatures above 450 Degrees F.

Applications Waste-to-Energy Coal Fired Boilers Incinerators

PTFE




Characteristic Rating Relative Cost $$$$$$$ Max Continuous Operating Temperature 500 Degrees F. Abrasion Good Energy Absorption Good Filtration Properties Fair Moist Heat Excellent Alkaline Excellent Mineral Acids Excellent Oxygen (15%+) Excellent

Pros Cons Teflon delivers superior dust cake release and high filtration efficiency in high heat applications that demand high resistance to acids and moist heat. Must oversize bag for shrinkage that can occur in temperatures above 450 Degrees F.

Applications Steel Foundries Coal Fired Power Plants Carbon Black Plants

Is your application operating at a high temperature over 275 degrees Fahrenheit? If so, there are many dust collector filter bag options to choose from. Outlined below is your guide to high temperature dust collector filter bags. We've broken down characteristics and properties of the top five most common filter media options. Aramid filter media, otherwise known by the brand name Nomex©, can handle up to a maximum continuous operating temperature of 400 degrees Fahrenheit. The main advantage of Aramid is how well Aramid can withstand high heat. In fact, Aramid media is commonly used in household oven mittens. Aramid is not ideal for applications looking for acid resistance.Aramid filter media is commonly used in asphalt plants and rock plants where there is high heat but are no chemical issues. You can typically distinguish an Aramid filter bag by its color. It is usually yellow and can have brown speckles which is caused by singeing.Fiberglass filter media has been the leading industry standard for dust collection applications where high temperatures above 500 degrees Fahrenheit are present. Fiberglass filter media is composed of a dense structure of fine fiberglass filaments. You’ll see Fiberglass used in industries such as energy, chemicals , and minerals.It is cost efficient when compared to similar high heat filter medias and is the most common choice for situations where heat is above 400 degrees Fahrenheit. Fiberglass can have a lot of variation in color, and depending on the application, can have different types of treatment (i.e. silicon, carbon). PPS , also otherwise known by the proprietary name Ryton© or Procon© is commonly used in dust collection applications that require excellent resistance to acids and alkaline. Out of all the options for high temperature filter medias, PPS has the lowest tolerance to heat in comparison with others but handles chemicals better. PPS can be used in applications with maximum continuous operating temperatures of 375 degrees Fahrenheit. PPS filter bag media is commonly used in carbon black, chemicals cement , asphalt, coal fired boilers, and incinerator applications. P84 (polymide) dust collector filter media is used in operating conditions of a maximum 500 degrees Fahrenheit. P84 performs well under dry high heat temperatures and can even withstand some elevated levels of moisture. P84 has a slightly better resistance to acids than PPS. This is a proprietary fabric that is imported from Germany to all manufacturers. For these reasons, P84 is one of the more expensive filter medias used in pulse jet baghouse dust collectors. P84 filter can be seen in used in waste to energy, power, lime kilns, smelting, glass and ceramic, and cement applications. PTFE , otherwise known as Teflon, is one of the most expensive dust collector filter medias used in pulse jet baghouse dust collectors . PTFE is considered a premium filter media because it can deliver superior dust cake release, withstand high heat temperatures of up to 500 degrees Fahrenheit, resist acids and moist heat. Cement, steel foundries, coal fired power plants, carbon black, steel and energy applications are just a few example of industries that use PTFE. PTFE is alfso known by its proprietary names Gore-Tex© and Tetratex©.Do you need more information after reading this guide to high temperature dust collector filter bags?

The advantages and disadvantages of Fiberglass filter bag

The advantages and disadvantages of Fiberglass filter bag

What is fiberglass filter bag?

Fiberglass filter bag is a traditional filter material, at the same time it is also the most widely used filter material in high temperature flue gas dust removal.

The advantages of Fiberglass filter bag:

Fiberglass filter bag is a filter material with reasonable structure and good performance , meanwhile , has the advantages of stable size 、minimal expansion rate and high intensity. Furthermore, felt fiber structure is in a single fiber state with  three-dimensional-pore structure which has high porosity. Fiberglass filter cloth can be used for a long time at 260°C which is base on its excellent performance in chemical erode resistant property and heat stability. At 300°C, the shrinkage of the glass fiber is close to zero and it also has good performance in dust stripping property and low energy for ash removal. Compare to other chemical fiber filter cloth, fiberglass filter cloth is appropriate used for rotary blowback bag filter.

Contact us to discuss your requirements of application of fiberglass filter. Our experienced sales team can help you identify the options that best suit your needs.

The disadvantages of Fiberglass filter bag:

(1)Running resistance is higher than the general chemical fiber filter cloth of high temperature.

(2)Poor wrinkle resistance which is seriously affect its lifespan.
