PTFE dust filter bag PTFE dust filter bag

  • Product Description
  • Technical Data Sheet

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. 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.
