GUANLIN FMS composite fiberglass filter bags, 260°C temperature resistance, for cement kiln, steel furnace and waste incineration high temperature flue gas dust collection.
FMS glass fibre composite needle felt filter bags for extreme high-temperature baghouses in cement kilns, steel furnaces, industrial boilers and waste incineration, rated 260°C continuous with excellent acid and alkali resistance at low cost per unit.
Description
FMS (fibre-grade composite) media blends glass fibre with a high-temperature synthetic fibre to deliver 260°C capability at a fraction of the cost of pure PTFE or ceramic media. GUANLIN FMS filter bags are the practical choice where gas temperature exceeds what PPS and aramid can survive but the budget cannot stretch to premium media.
Why Choose GUANLIN FMS Filter Bags
- 260°C continuous rating — handles kiln and furnace exhaust that would destroy PPS or aramid.
- Glass fibre composite structure — glass fibre provides the temperature backbone while the synthetic component improves flex life and abrasion resistance.
- Acid and alkali resistance — withstands the SO₂, HCl and alkaline dust chemistry typical of cement and incineration.
- Cost-effective at high temperature — a fraction of PTFE or ceramic media cost for comparable duty.
- ≥99.9% filtration efficiency — dense needle-punched structure captures fine particulate down to 1 μm.
- Good dimensional stability — low shrinkage at temperature keeps the bag snug on the cage.
- Custom sizing — Ø130–160 mm × 2000–6000 mm to your drawing.
- Matched high-temperature cages — stainless steel or silicone-coated cages supplied as a set.

Application Scenarios
Cement kiln and preheater exhaust
Kiln gas at 200–260°C with alkaline clinker dust and sulphur compounds is the classic FMS duty. The glass fibre backbone survives the temperature while the composite structure resists the abrasion that pure glass media cannot.
Steel making and electric arc furnaces
Furnace and ladle hood exhaust carries hot metal oxide fume with temperature spikes above 250°C. FMS bags absorb the excursions that would embrittle aramid.
Waste incineration and hazardous waste
Incinerator flue gas at 200–260°C with HCl, SO₂ and heavy metal fume is handled by the composite media, especially with a PTFE membrane for dioxin control.
Industrial boilers and biomass combustion
Where flue gas temperature runs higher than a standard PPS installation can tolerate, FMS provides a cost-effective upgrade without changing the baghouse.
Non-ferrous smelting and roasting
Roasters and converters discharge hot, acid-bearing gas with fine oxide fume; FMS handles both the temperature and the chemistry.
Glass, ceramics and refractory kilns
Kiln exhaust with alkaline dust and 200–260°C temperature is well matched to FMS media.

Applicable Working Conditions
- Continuous gas temperature ≤260°C (500°F), short-term peak ≤280°C (536°F)
- Acid and alkali bearing dust and flue gas

FAQ
Q1. What does FMS stand for?
A glass fibre composite needle felt media combining glass fibre for temperature capability with synthetic fibre for flex life.
Q2. What is the maximum temperature?
260°C (500°F) continuous, 280°C short-term peak.
Q3. Why choose FMS over PTFE?
Comparable temperature capability at significantly lower cost, though PTFE offers better chemical resistance in the most aggressive streams.
Q4. Is it suitable for cement kilns?
Yes, it is one of the most common media for kiln and preheater exhaust where temperature exceeds aramid limits.
Q5. Does it resist acid attack?
Yes, it performs well against SO₂, HCl and alkaline dust within the rated temperature.
Q6. What sizes do you supply?
Ø130–160 mm standard, 2000–6000 mm length, fully customisable.
Q7. What is the MOQ and lead time?
MOQ 10 pcs, 7–15 days for standard sizes.
