DF..QE Series Manifold Mount Filters (4568 PSI)

The HYDAC DF…QE Series high-pressure manifold mount filters provide reliable filtration for demanding hydraulic systems. Rated up to 4,568 psi with flow rates up to 110 gpm, they feature rugged high-fatigue-strength construction, easy element replacement, optional bypass valves and multiple clogging indicator options.

Product Description

DF..QE Series Manifold Mount Filters (4568 PSI)

Features:

The DF…QE Filters have a filter head of ductile iron and a screw-in bowl of cold-formed steel for high fatigue strength.
• The filter housings are designed to withstand pressure surges as well as high static pressure loads.
• The screw-in bowl or lid/cap allows the filter element to be easily removed for replacement or cleaning.
• Visual (pop-up), electrical, electrical/visual (lamp), or electronic differential type clogging indicators can be installed.
• DF…QE filters are available with or without a bypass valve located in filter head, so either high or low collapse pressure
elements may be used.
• Fatigue pressure rating equals maximum allowable working pressure rating.
