Product Description

In-Line Duplex Industrial Filter (DFDK Series 4568 PSI)

The HYDAC DFDK Series high-pressure inline duplex filter provides continuous, reliable filtration for demanding hydraulic systems. Rated up to 4,568 psi with flow rates up to 90 gpm, it features rugged construction, a ball valve selector and multiple clogging indicator options for efficient operation and maintenance.

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 or lid, 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.
• DFDK sizes 330 and above can be ordered with a T Ball Valve which can operate in mid position with both elements fully open
and online in parallel.
Note: QPD is available in sizes 160-1320 only.
