Extreme Chemical Resistance for Demanding Industrial Filtration
In the world of industrial filtration, aggressive fluids and high-temperature applications present unique challenges that standard filter media cannot meet. Eaton PTFE (Polytetrafluoroethylene) Chemical Resistant Filter Bags are engineered specifically for these extreme environments. As a premium filtration solution available through Purecowater, these bags offer unmatched durability, ensuring process stability where other materials fail.
Whether you are filtering hot acids, concentrated alkalis, or aggressive solvents, Eaton’s PTFE filter bags provide a reliable barrier that maintains integrity under stress, preventing bypass and ensuring consistent product quality.
What Sets Eaton PTFE Filter Bags Apart?
The core advantage of these filter bags lies in the material itself. PTFE is one of the most chemically inert substances available, making it the ideal choice for filtration processes involving reactive chemicals. Unlike Polypropylene (PP) or Polyester (PE) bags, which may degrade, swell, or dissolve in the presence of strong oxidizers or continuously high temperatures, PTFE remains stable.
Key Features and Benefits
- Broad Chemical Compatibility: Withstands exposure to the full pH range (0-14), including aggressive acids, bases, and organic solvents.
- High Thermal Stability: Capable of operating at temperatures up to 500°F (260°C), significantly higher than standard synthetic media.
- Hydrophobic Nature: Naturally repels water, making it suitable for separating water from non-aqueous phases or for specialized gas filtration applications.
- Low Friction Coefficient: Facilitates excellent cake release properties, making cleaning and reuse possible in certain non-critical applications.
- Compliance: Manufactured to meet rigorous industrial standards, ensuring safety in chemical and pharmaceutical processing.
