Description
- High Efficiency Filtration
Stable and efficient filtration with two-layer PTFE films producing little stretches due to aging or vibrations. 0.003μm particle capture test conducted by nucleus particle counter for all products.
- Low Pressure Loss
High flow rate and low pressure loss by PTFE’s two-layer structure and high hole rate. Much lower pressure loss especially for STF-4 series by large effective filtration area from film laminate structure.
- High Corrosion Resistance
Fluorine resin used for element film, element support, O-ring etc., while SUS316L used for housing and every gas contacting part polished to R max 0.5μm and passivation process.
