*1 The surface dimensions are calculated value, and not guaranteed.
*2 The value is just for your reference.
The value is calculated with the flux under the following in-company measuring condition.
Flux of the polysulphone hollow fiber : 20 L / min / m^2 or more
Test condition

  • Feed Water: Pure Water
  • Water Temperature: 20 Degrees Centigrade (°C)
  • Feed Water Pressure: 0.1 MPa

The flux value is a lower limit under the above-mentioned condition. The performance of the module differs individually and differs according to the actual use conditions. There is no measured data of individual modules.



The pores of the outer layer are structured to be very precise, whereas the intermediate layer structured to be more rough. This realizes high removal as well as high flux in membrane performance.



  • The material is polysulfone
  • Low Elution
    • Safe enough to be applied to artificial kidney.
      Standard Toray Sample A Sample B
    Dimethlacetamide (DMAC) <0.2mg/L <0.005mg/L 1.4mg/L 1.5mg/L
  • Dry membrane    
    • Easy to handle, transport, assemble and store
    • Effective performance even after once dried during use
