Low pressure drop ePTFE HEPA media
Huzhou Kaili New Material Technology Co., Ltd. offers a specialized line of Low Pressure Drop ePTFE (expanded Polytetrafluoroethylene) HEPA media. Traditional fiberglass HEPA filters often create significant resistance to airflow, forcing HVAC systems to work harder. Our ePTFE membrane technology features a unique, highly uniform microporous structure that captures 99.97% to 99.99% of particulates while allowing air to pass through with minimal resistance.
Operating from our 3,000m² facility in the Yangtze River Delta fluoromaterial cluster, we provide the core filtration media that powers the next generation of energy-efficient cleanrooms and high-end air purifiers.

The Advantage of Low Resistance Technology
- Reduced Energy Consumption: Our ePTFE media can reduce the initial pressure drop by up to 40%–50% compared to traditional micro-fiberglass media. This translates directly into lower utility costs for large-scale facilities.
- Surface Filtration Excellence: Unlike depth-loading fiberglass that clogs internally, our ePTFE membrane captures dust on the surface. This prevents "pressure drop spikes" and ensures a stable, linear performance over the filter's lifespan.
- High Mechanical Strength: The expanded fluoropolymer structure is exceptionally durable and resistant to pleat damage or "pinholing" during the filter assembly process, ensuring 100% leak-free performance.
- Hydrophobic & Chemically Inert: Naturally repels moisture and resists degradation from common cleaning agents or corrosive gases, making it ideal for pharmaceutical and semiconductor environments.
- Zero Off-Gassing: Our high-purity virgin ePTFE is ideal for "Boron-free" and "Silicone-free" cleanroom requirements, preventing chemical contamination in sensitive manufacturing processes.
