① food grade, no additives PP is used, but due to production small amounts of other materials might be used, please consult us for chemical resistance
② VMQ O-ring material is possible
③ module should be connected fexibly, to allow temperature dilatations and eliminate material stress

Possible Applications

  • Gas transfer, microporous hollow fiber membrane is used so gas/liquid or liquid/gas
  • Gas filtration - gas/solids separation on microfiltration level
  • Membrane degassing and various industry processes

Applications Notes

  • Ports are plastic, excessive tightening moments and forces will cause breakage.
  • Try to avoid temperature shocks, slow change is preferable. For contactor (liquid / gas, degassing) applications temperature gradients might cause condensation inside the pores, wetting and module bleeding. When this happens thorough drying (dry air @50°C at least 24 hours) will restore the module.
  • No oxidizing chemistry or UV light – PP membrane is very sensitive. For chemical cleaning use standard NaOH / citric acid procedure.
  • Chemical resistance can be estimated from used materials PP, PVCu, polyurethane, usually least resistant is potting - polyurethane.

Custom Options

There are other custom variations of the D50 HZ Module:
  • Length from 500 to 1 000mm
  • Membrane P80, custom or customer supplied
  • Port type can be modified as needed
  • O-ring material silicone, EPDM
