Filter Fabric

In modern industries, controlling and treating dust and emissions are crucial factors for ensuring a safe working environment, complying with environmental regulations, and optimizing production efficiency. The baghouse dust collection system, with its two main components—filter media and filter cages—plays a vital role in removing fine dust particles, contributing to the protection of both human health and machinery.

What is the Filter fabric?

Filter fabric is a woven or non-woven material manufactured from various types of synthetic and inorganic fibers that meets the requirement for efficient filtration in baghouse dust collection systems.

The production line adheres to European standards to ensure consistent input and output quality. This, combined with highly automated technology, guarantees a uniform fabric surface, tight seams, precise stitching, and optimal filtration efficiency and lifespan. Selecting the correct filter media that precisely matches the operating conditions and environment is a crucial factor for ensuring filtration effectiveness, long lifespan, and optimal operating costs.

Technical Specifications of Basic Fiber Types

Below is a summary table of the main filter fiber properties, including density, tenacity (tensile strength), working temperature and peak temperature (short-term temperature resistance), and the Oxygen Limit Index (OLI), which indicates the material’s ability to sustain combustion:

Filter Media Technical Specifications

Depending on the characteristics of the exhaust gas and the working environment, filter media types are selected based on their resistance to heat, chemicals, and abrasion. Below are the common filter media types:

Chemical Resistance and Working Environment

Fiber types demonstrate resistance to various chemical factors—strong/weak acids, strong/weak alkalis, solvents, oxidation, hydrolysis, and more—with performance ranging from “Very Good” to “Poor”. Below are some typical evaluations:

• PTFE and Glass Fiber offer very good resistance to most chemicals; PTFE fabric, in particular, demonstrates comprehensive chemical inertness.
• PPS offers very good resistance to alkali, acid, and hydrolysis, but its oxidation resistance is moderate.
• Aramid and Acrylic (Homopolymer) show good resistance to abrasion and hydrolysis; Aramid also offers higher heat resistance.
• Polyester and Polyamide show moderate to poor chemical resistance and are susceptible to degradation under high temperature and high humidity.

Role and Application of Filter Media in Industries

• Blocking particulate matter and fine dust: Ensuring clean exhaust gas that meets environmental requirements.
• Resistance to chemicals, temperature, and corrosion: Filter media is selected based on the environment (heat, chemicals, moist dust, etc.).
• Enhancing lifespan and saving costs: Suitable media helps limit replacement frequency, reducing maintenance costs.
• Applications: Cement, steel, hot mix asphalt, animal feed, waste incineration, thermal power, chemicals, fertilizer, wood, paper, pharmaceuticals, etc.

Guidelines for Selecting Appropriate Filter Media based on Specific Needs

• Medium temperature (<150∘C), dry environment → Polyester (cost-effective, high performance)
• Moist environment, high humidity → Polyester with oil- and water-repellent finish or Acrylic
• High temperature (180–200∘C), acidic/alkaline chemicals → PPS (Ryton)
• Very high temperature, high abrasion, strong oxidation → Nomex (Aramid), or P84 if higher heat resistance is required
• Requirement for anti-static properties – in cement, flammable chemicals → Anti-static Polyester
• Gas containing extremely strong chemicals, high heat, and oxidation → PTFE or Glass-ePTFE (optimal durability)
