PTFE Gas Filter for High Withstanding Pressure STF-3000 Series
- High Efficiency Filtration
Stable efficiency filtration with two-layer filtration film made of PTFE with little stretches by aging or vibration. 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. - 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 .
