Low Pressure Loss PTFE Gas Filter TF Series

  • High Efficiency Filtration
    Stable efficiency filtration with two-layer filtration film made of PTFE causing little stretches by aging or vibration. 0.01μm 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 TF-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 or less and passivation process.
Filtration Accuracy 0.01μm
