Alkali resistance PTFE air filter bag for industrial use
Description:
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. has an extreme high cost and is typically used after
everything else has failed. 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.
