DF...QE Series
Manifold Mount Filters
4500 PSI • Up to 180 GPM
|
|
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 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 so either high or low collapse pressure elements may be used.
- Fatigue pressure rating equals maximum allowable working pressure rating.
