Click to Enlarge

HDF series drains are compact and highly reliable automatic float controlled condensate drains for industrial compressed air treatment applications. Due the fact that the drain never runs completely dry, no air is lost during the discharge process. HDF series condenste drains therefore reduce the waste of compressed air which has a positive effect on the efficiency of the whole compressed air system.

  • No need for electrical wiring, as no power supply is require
  • Manual drain valve for discharge and operational check fitted as standard
  • Improved reliability due to large cross section outlet valve opening which minimizes the chance of blockage
  • A low velocity condensate outlet ensures that no emulsion is created and supports installation of a static oil/water separator
