Pressure Equalization Venting Technology
Advanced ePTFE vent membrane solutions for waterproofing, dust protection, and stable pressure balance in sealed systems.
What is Pressure Equalization Technology
Pressure equalization technology uses a microporous ePTFE membrane that allows air exchange while blocking liquids, dust, and oils.
- Prevents container deformation
- Balances internal and external pressure
- Improves transport stability
- Protects sealing systems
How Venting Works
- Pressure increases due to temperature change
- Air passes through microporous membrane
- Pressure is balanced instantly
- Liquids are blocked by hydrophobic structure
Technical Mechanism
Microporous ePTFE Structure
- Micron-level pore control
- Gas-permeable / liquid-blocking
- Stable under pressure difference
Key Benefits
