Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 25 years of expertise since 1998. Our Stainless Steel Fiber Felt Filter Bag is engineered for demanding chemical filtration applications, featuring a precise 0.5 micron rating and constructed from premium 316L stainless steel. This filter bag is designed to withstand high pressure environments, making it an ideal solution for aggressive chemical processes where reliability and efficiency are paramount. With our deep understanding of filtration needs, we deliver a product that combines durability, precision, and cost-effectiveness.
Our filter bag utilizes a stainless steel fiber felt structure, which provides a three-dimensional depth filtration mechanism. Unlike traditional woven or mesh filters, the fiber felt captures particles throughout its entire thickness, offering high dirt-holding capacity and longer service life. The 316L material ensures excellent corrosion resistance in acidic, alkaline, and solvent-based chemical environments. Additionally, the bag can withstand high temperatures up to 450°C and pressures up to 30 bar, making it suitable for extreme conditions such as hot gas filtration, polymer processing, and catalyst recovery.

Key Features & Benefits:
- High Filtration Efficiency: The 0.5 micron absolute rating ensures removal of fine particles, meeting stringent chemical purity requirements.
- Excellent Chemical Compatibility: 316L stainless steel resists corrosion from acids, alkalis, and organic solvents, extending filter life in harsh environments.
- High Temperature & Pressure Resistance: Suitable for processes up to 450°C and 30 bar, reducing the need for cooling or pressure reduction steps.
- Reusable & Washable: The fiber felt structure can be cleaned via backwashing, ultrasonic cleaning, or chemical washing, reducing replacement costs.
- Customizable Design: We offer various sizes, connection types, and optional gaskets to fit existing filter housings.
- Low Pressure Drop: The open fiber structure minimizes flow resistance, saving energy in continuous filtration systems.
- Long Service Life: Compared to disposable filter bags, stainless steel fiber felt bags can last for years with proper maintenance, lowering total cost of ownership.
Typical Applications:
- Chemical processing: catalyst recovery, solvent filtration, acid purification
- Petrochemical & refining: hot gas filtration, polymer melt filtration
- Pharmaceutical: active ingredient filtration, sterile air/gas filtration
- Environmental: industrial wastewater treatment, scrubber liquid filtration
- Food & beverage: edible oil filtration, syrup clarification
