1. Product Overview
Pleated filter bags are an upgraded version of traditional round dust collection bags. The filter media is pleated during processing, which significantly increases the effective filtration area for the same installation dimensions, resulting in higher dust removal efficiency and lower operating resistance. These products must be used with specialized pleated cages and are widely applied in flue gas dust control in industries such as cement, steel, power generation, waste incineration, chemicals, metallurgy, and coking.
2. Temperature Resistance Parameters for Common Materials
• Polyester with PTFE coating: 130°C (continuous), 150°C (short-term); commonly used in dry dust applications at ambient temperatures
• PPS with PTFE coating: 160–190°C (continuous); resistant to acidic flue gas; commonly used in power plants and waste incineration facilities
• Aramid (Nomex): Continuous 210°C, peak 240°C; suitable for high-temperature hard dust and blast furnace flue gas applications
• Basalt/glass fiber composite: Designed for ultra-high-temperature conditions with excellent flame-retardant properties
3. Product Advantages
✅ Pleats increase the filtration area, enabling higher airflow capacity without modifying the dust collector housing
✅ PTFE-coated surface filtration prevents dust penetration, ensures thorough cleaning, and reduces the likelihood of bag clogging
✅ Optional anti-static treatment meets explosion-proof requirements for flammable and explosive dusts such as pulverized coal and aluminum powder
✅ Custom-designed pleated cage frames (with reinforced vertical ribs and a dual-support ring structure) provide sturdy support and prevent deformation
✅ Multiple mouth sealing options, including spring expansion rings and clamps, ensure a tight seal during installation, preventing air leakage and dust escape
4. Compatible Components and Customization Services
We can manufacture compatible accessories such as pleated cages, Venturi tubes, and spring expansion rings of the same specifications; we support customization based on provided drawings or samples for outer diameter, length, filter media thickness, and post-treatment processes to meet the requirements of various project operating conditions.
