How to Choose the Filter Bag Material for Bag Filter Dust Collectors? – Professional Advice from Anhui Tiankang Environmental Technology Co., Ltd.

The core component of a bag filter dust collector is the filter bag, and its material directly affects filtration efficiency, operating costs, and equipment lifespan. As a high-tech enterprise specializing in environmental protection and pollution control, Anhui Tiankang Environmental Technology Co., Ltd. has extensive experience in designing bag filter systems for industries such as steel, cement, pharmaceuticals, and glass. Below, we analyze key considerations for selecting filter bag materials based on industrial application requirements:

1. Selecting Filter Media Based on Dust Characteristics

• High-temperature dust (e.g., steel, cement industries) : High-temperature resistant materials such as P84 (polyimide) , PTFE (polytetrafluoroethylene) , or glass fiber membrane-coated filter media are required, capable of withstanding temperatures above 200°C for extended periods.
• Corrosive gases (e.g., chemical, pharmaceutical industries) : PTFE filter bags or FMS (Fluorine-Modified Composite) filter media are recommended due to their strong resistance to acid and alkali corrosion.
• Sticky dust (e.g., asphalt, tar) : Anti-stick coated filter media or PTFE membrane-coated filter bags should be used to prevent clogging.

2. Matching Filter Material with Cleaning Method

• Pulse-jet cleaning : Suitable for high-strength polyester (PE) or Nomex filter bags , which offer excellent mechanical wear resistance.
• Reverse-air cleaning : Glass fiber filter bags or PPS (polyphenylene sulfide) are recommended due to their flexible structure, which accommodates low-frequency cleaning.

3. Balancing Cost and Lifespan

• Low-cost applications : For standard working conditions, polyester (PE) filter bags can be used—they are inexpensive but have a shorter lifespan (1-2 years).
• Longevity requirements : High-value industries (e.g., pharmaceuticals, food) should opt for PTFE membrane-coated filter bags . Although the initial cost is higher, their service life can exceed 5 years.

4. Customized Solutions from Anhui Tiankang

With extensive experience in steel plants (sintering, steelmaking), cement plants, and non-ferrous metal smelting, Anhui Tiankang provides:

• Filter material testing services : Analyzes dust samples to recommend the optimal filter media combination.
