Quick Summary
A guide to industrial filter bags for plants operating over 275 degrees Fahrenheit. Includes high an overview of temperature filter media such as Fiberglass, PPS, P84, Aramid, and PTFE>
High Temperature Filter Bags
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 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.

Applications

Cupolas
High Temp Dryers
Fiberglass
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).

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.
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.

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.
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

We are looking for pleated cartridge filters (similar to those standard FARR type) that can withstand temperature of up to 190 degree Celsius. Each should have filter area of 225 sq. ft. or 21 sq. metres.
Application for incinerator fly ashes and dust.
Instead of baghouse, we are looking for cartridge type to save on foot print.
