Advanced PTFE Membrane Filter Bags designed for extreme industrial environments, engineered for maximum durability in the harshest operating conditions.
Our PTFE (Polytetrafluoroethylene) filter bags deliver unparalleled filtration efficiency and extended service life. Featuring a proprietary microporous ePTFE membrane laminated onto PTFE felt substrate, these bags achieve >99.99% filtration efficiency for sub-micron particles while maintaining ultra-low pressure drop.
Key Advantages
Extreme Temperature Resistance: Stable performance from -260°C to +260°C (-436°F to 500°F)
Unmatched Chemical Immunity: Resists all acids, alkalis, and solvents (including HF acid)
Zero Moisture Absorption: Hydrophobic surface prevents blinding in humid environments
Non-Stick Surface: Reduces cake buildup and enables effortless pulse-jet cleaning
Extended Lifespan: 5x longer service life compared to conventional fiberglass/P84 bags
Waste incineration flue gas (dioxin/furan capture)
Chemical processing industries
Carbon black & titanium dioxide manufacturing
High-temperature metal smelting fumes
