High-Temperature Composite Fiberglass Dust Collector Media
The FMS Filter Bag (Fiberglass Mixed Synthetic) is a high-performance composite needle felt designed for extreme-heat dust collection environments where standard polyester bags would quickly melt or degrade. By blending alkali-free glass fibers with high-temperature synthetic fibers (such as Nomex, P84, or PPS), FMS media overcomes the structural brittleness of pure fiberglass while remaining significantly more cost-effective than 100% premium synthetic bags. Operating continuously at temperatures up to 260°C (500°F), it delivers a 99.9% filtration efficiency for blast furnaces, cement kilns, and waste incineration plants.

Features of FMS Filter Bag: Quality, Value & Expertise
FMS filter bag is a high-performance filtration material, which combines a variety of high-temperature-resistant fibres and is made through a special process, aiming to meet the filtration needs of industrial production for high temperature, corrosion, abrasion and other harsh environments. The following is the detailed introduction of FMS filter bag:
Material Composition: FMS filter bags are usually made of alkali-free glass fibre staple yarn, aramid, P84 and other high-temperature-resistant fibres mixed in a certain proportion. These materials give the filter bag excellent physical and chemical properties.
High Temperature Resistance: FMS filter bags are able to withstand temperatures up to 260 degrees Celsius, with transient temperatures even reaching 300 degrees Celsius. This characteristic enables it to maintain good filtration performance and stability under high temperature environment.
Corrosion resistance: FMS filter bag made of polytetrafluoroethylene (PTFE) membrane material has excellent corrosion resistance. It can resist the erosion of many chemicals, including acids, alkalis, salts and other corrosive substances.
Filtering Efficiency: The filtration efficiency of FMS filter bag can reach more than 99.99%, which can effectively filter tiny particles and harmful gases. Its unique fibre structure and surface area coefficient make the dust mostly concentrated on the surface of the filter media, and it is more difficult to penetrate into the filter media to block the voids.
Wear resistance and folding resistance: P84 fibres are added on the basis of glass fibre needle felt, which makes the felt layer more compact and enhances the entanglement between fibres, thus improving its wear resistance and folding resistance.
Dust-cleaning effect: The surface of FMS filter bag has been specially treated with excellent hydrophobicity and anti-static properties, which is not easy to attach dust and has a better dust-cleaning effect.
Applications: FMS filter bags are widely used in iron and steel, smelting, chemical industry, carbon black, building materials, electric power and other industries, providing efficient dust filtration solutions for these industries.
Economy: Compared with synthetic chemical fibre high temperature resistant filter media, FMS filter bag overcomes the weaknesses of chemical fibre filter media such as large elongation, large deformation, low temperature resistance and poor corrosion resistance, and the price is relatively low.
In short, with its excellent high temperature resistance, corrosion resistance, abrasion resistance and high efficiency filtration efficiency, FMS filter bag plays an important role in industrial production, and is the ideal filtration material for high temperature and corrosive environment.

FMS Filter Bags: Quick FAQ
Q1: What exactly is an FMS filter bag material?
FMS (Fiberglass Mixed Synthetic) is a high-performance composite needle felt. It blends alkali-free glass fibers with high-temperature synthetic fibers (such as P84, Aramid, or PTFE) to overcome the structural brittleness of pure fiberglass while keeping production costs significantly lower than 100% pure synthetic options.
Q2: What is the maximum operating temperature threshold?
FMS filter bags handle a continuous operating temperature of up to 260°C (500°F), with short-term dry-heat surge limits reaching 280°C (536°F). This makes them ideal for blast furnace gas, cement kilns, and waste incineration plants.
Q3: How do FMS composite elements improve on pure fiberglass?
By needling synthetic fibers into the glass matrix, FMS media achieves:
Folding & Wear Resistance: Eliminates fiberglass micro-fracturing from high-frequency pulse-jet flexing.
Higher Airflow: Allows a higher filtering wind speed while maintaining a lower initial running resistance drop (1000 Pa to 1450 Pa).
Q4: What is the chemical resistance profile of FMS bags?
FMS bags expand the chemical window of traditional glass fibers, stably operating across a pH chemical resistance window of pH 1 to pH 12. The inclusion of P84 or PTFE fibers protects the glass cores against aggressive SOx and NOx acid hydrolysis in flue gases.
Q5: Why is P84 often added to the FMS fiber blend?
P84 (polyimide) fibers feature a unique trilobal cross-section. When blended into FMS needle felt, this shape drastically increases the surface area matrix, trapping ultra-fine particulate directly on the surface layer and preventing deep pore blinding.
Q6: What are the standard physical tolerances for FMS bags?
To prevent hazardous dust bypass leaks in heavy-duty baghouses, high-precision factory lines manufacture FMS bags to tight physical tolerances of ±0.5mm on the snap-band cell plate diameter and ±10mm on the overall flat bag length.
Q7: Which surface treatments optimize FMS performance?
PTFE Impregnation / Bath: Coats individual fibers to protect against high-sulfur chemical attack.
ePTFE Membrane Lamination: Achieves ultra-low emissions (<5 mg/Nm³) by restricting filtration strictly to the surface layer.
Q8: What specifications are required to request a B2B factory price quote?
To receive accurate volume pricing for senotay.com inquiries, provide the exact cell plate hole diameter, total flat length, material blend ratio (e.g., Fiberglass + P84), top/bottom connection configurations, and your flue gas chemistry.
