PTFE dust filter bag






 



Introduction

----------------------------------------------------------------------

PTFE dust filter bag 

Teflon PTFE dust filter bag (Fluorocarbon fiber/Polytetraflouroethylene aka PTFE).
Normal maximum continuous operating temperature is 240degrees. Generally used for severe chemical environments

 at high temperatures.Common applications include coal-fired power plants, cement production, and steel foundries.
Chemical resistance is excellent and abrasion resistance is generally superior to protein fibers,
but not as good as most synthetics. 

 

Features

 ● PTFE is one of the best fibers with outstanding chemical and thermal resistance, operating,operating up to 240℃

● Teflon has an extreme high cost and is typically used after
● Everything else has failed. Teflon is available in both a woven and a felt finished product.
● This media has poor flex abrasion qualities and requires a 20 vertical wire minimum support cage when used in tubular bag form.
