Woven Fiberglass Filter Bag
High-Temperature & Corrosion-Resistant Filtration Solution
Engineered for extreme industrial environments, our woven fiberglass filter bags withstand continuous 500°C temperatures and resist acid/alkali corrosion (pH 2-12). Ideal for coal-fired boilers, waste incinerators, and metallurgical kilns, ensuring stable dust capture and reducing equipment wear.
Key Features
Ultra-high temperature resistance (500°C continuous, 550°C peak)
High-strength woven structure (warp tensile strength ≥1200N/5cm)
Uniform pressure design, 30% improvement in cake release rate
Performance Benefits
Initial operating resistance ≤150Pa, 15% energy savings
Powder-coated cage frames, corrosion life extended to 8 years
Optional "full bag status indicator"
