DFDK Series
Inline Duplex Filters
4500 PSI • Up to 90 GPM

Hydac_DFDK Series Filter

Features

  • The DFDK Filters have a filter head of ductile iron and a screw-in bowl of cold-formed steel.
  • The filter housings are designed to withstand pressure surges as well as high static
    pressure loads.
  • The screw-in bowl allows the filter element to be easily removed for replacement or cleaning.
    A visual (pop-up), electrical, electrical/visual (lamp), or other electronic differential types of clogging indicators are available to suit each application.
  • DFDK filters are available only with high collapse pressure elements since no bypass is provided.
