An FMS Filter Bag is a specific type of industrial filter bag designed to meet precise dimensional and performance standards. "FMS" often refers to a set of manufacturing specifications that ensure consistency, quality, and interchangeability. These bags are engineered as exact OEM (Original Equipment Manufacturer) replacements for pulse-jet dust collection systems, guaranteeing a perfect fit, optimal cleaning performance, and maximum filtration efficiency.
An FMS Filter Bag is a high performance industrial filter media designed for demanding dust collection and filtration systems. It is Made from a composite blend of fiberglass, meta-aramid (Nomex) and PPS fibers. The bag able to provide exceptional resistance such like high temperatures, chemical corrosion and mechanical stress.
These filter bags are engineered for high-temperature dust removal that especially in industries such as cement, steel, smelting and waste incineration, where It conventional polyester bags fail to perform.
How It Works:
The FMS bag’s multi fiber composite structure combines the thermal stability of fiberglass with the flexibility of aramid and the chemical resistance of PPS. This unique composition forms a dense micro-pore network that captures fine dust particles while maintaining excellent air permeability and structural integrity.
Superior Temperature Resistance: It Performs reliably up to 260°C or 500°F.
Enhanced Mechanical Strength: The system Resists tearing, abrasion and pulse-jet stress.
Longer Service Life: Lasts 2–3x longer than standard polyester or acrylic filter bags.
Improved Filtration Efficiency: Its internal fnctions Achieves up to 99.9% dust removal in high-load applications.
Stable Performance in Harsh Environments: Ideal for acidic or high-moisture flue gases.

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.
