100% Heat Resistant PTFE Needle Punching Dust Filter Bag
Material: PTFE needle felt 750gsm
Also can be made of woven ptfe.
1. High temperature resistance
2. Excellent acidity resistance
3. Excellent alkalinity resistance,
4. High filtration efficiency
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.
Specification:
Size: diameter 100mm, 125mm, 130mm, 150mm, 180mm, 250mm ect.
Any length is available. Special size is customizable.
Process Method: sewing or welded
Dust collector filter bag tops include:Beaded snap band top, corded or ring top, raw top, flat sewn top, top with grommet, top with loop, gasket top and other.
