Hydrophobic PTFE Pleated Membrane Filter Cartridge
Product Overview
The Hydrophobic PTFE Membrane Pleated Cartridge is engineered for critical gas and air filtration applications that demand high chemical resistance, sterility, and durability. Featuring a hydrophobic polytetrafluoroethylene (PTFE) membrane, this filter is ideal for sterile gas venting, compressed air systems, solvent filtration, and aggressive chemical environments.
Its pleated construction increases surface area and ensures high flow rates with low pressure drop, while maintaining 0.1 to 1.0 micron filtration precision (typically 0.2μm for sterile applications). Constructed with all thermally bonded components and non-leaching materials, it provides excellent compatibility with strong acids, alkalis, and solvents.
This cartridge is widely used in biopharmaceuticals, food & beverage gas filtration, semiconductor processing, and chemical manufacturing. Available in various lengths and end cap configurations to fit most standard filter housings.
Key Features
✅ Ultra-Hydrophobicity & Gas Permeability
· PTFE hydrophobic membrane inherently repels liquids while allowing gas passage, effectively blocking microbes and liquids. Ideal for sterilizing compressed air, nitrogen, and other gases, preventing cartridge clogging.
✅ Exceptional Chemical Resistance
· Resistant to strong acids, alkalis, organic solvents (e.g., acetone, DMSO), and oxidizing agents (e.g., ozone). Suitable for pH 1-14 environments, perfect for corrosive gas and solvent filtration.
✅ Precision Particle Retention
· Controlled pore sizes (0.01µm, 0.1µm, 0.22µm) ensure >99.99% efficiency in capturing bacteria, aerosols, dust, and submicron particles.
✅ High-Temperature Resistance & Repeatable Sterilization
· Withstands steam sterilization (121°C, 30 minutes) and supports SIP (steam-in-place) or multiple autoclaving cycles, extending service life.
✅ Low Pressure Drop & High Flow Rate
· Pleated design maximizes filtration area, combined with PTFE’s low gas flow resistance, enabling high throughput and energy efficiency for large-scale gas systems.
