product detail

FMS, also known as Flumex is a mixture of P84 fiber or two or more other high-temperature resistant fibers added to the glass needle felt. The felt layer is tighter and the entanglement between fibers is stronger. Which can cope with higher filtration wind speeds. It has efficient corrosion resistance, high temperature resistance, acid and alkali resistance, folding and wear-resistant composite needle felt.

Compared with pure glass fiber filter material, FMS filter material has significantly improved wear resistance, bending resistance, and peel strength and can withstand high filtration loads.

The filtration speed can reach over 1.0m/min and the operating resistance is low. Compared with synthetic fiber and other high-temperature resistant filter materials, it overcomes the weaknesses of high elongation, large deformation and poor corrosion resistance.

The size stability and strength are better and the price is lower than other high-temperature resistant chemical fibers making it more cost effective.

Technical characteristics of FMS high-temperature resistant filter material:

1. Can withstand high gas temperatures. In general, the operating temperature can be between 260 ° C and 300 ° C and some varieties can withstand a high temperature of 350 ° C instantly.

2. It can bear high filtration loads, with a gas filtration load of 60-90m3/nf hour.

3. It has very low operating resistance and is more suitable for changes in blast furnace fan air volume.

4. High filtration efficiency, the dust content of filtered gas is generally less than 3-5 mg/nm3 °

5. It has a long service life and greatly superior cost-effectiveness compared to fiberglass needle felt filter materials. It has a cost about 10-20% higher than fiberglass needle felt, but its service life is more than twice under similar operating conditions.

FAQ

Q
What is FMS (Fluorocarbon) filter media? What are its main characteristics?
A
FMS (Fluorocarbon) filter media is a composite high-temperature resistant needle-punched felt, made by blending and layering two or more types of high-temperature resistant fibers. Its core characteristics include exceptional high-temperature resistance, high strength, excellent acid and alkali corrosion resistance, abrasion resistance, and fold resistance.
Q
What is the grammage (GSM) range for this FMS filter media?
A
This FMS filter media has a grammage range between 800-900 GSM, falling within the high-grammage series. It provides enhanced mechanical strength and durability.
Q
How does the FMS filter media perform in high-temperature environments?
A
FMS filter media exhibits outstanding temperature resistance. Different product series are suitable for temperature ranges of 150-200°C (300-392°F) and 250-300°C (482-549°F). Certain models can withstand continuous operation at 204-260°C (392-500°F) and momentary exposure up to 230-400°C (446-712°F).
Q
What is the function of the P84 fibers added to FMS filter media?
A
P84 fibers feature a unique trilobal cross-section that creates a high surface area coefficient, increasing dust capture probability. This structure also concentrates dust primarily on the media surface, preventing penetration into internal pores and reducing operational resistance, thereby enhancing filtration air velocity.
Q
What advantages does FMS filter media offer over standard glass fiber media?
A
Compared to glass fiber media, FMS filter media demonstrates significantly improved abrasion resistance, flexural strength, and peel strength. It can handle higher filtration loads, achieve filtration velocities exceeding 1.0 m/min, and maintain lower operational resistance.
