Rated up to 4,568 psi, they feature rugged construction, easy element replacement, optional bypass valves and multiple clogging indicator options for dependable system protection.

Product Description

Manifold Mount (Top) Industrial Filter (DFP Series 4568 PSI)

Features:

• 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.
• A visual (pop-up), electrical, electrical/visual (lamp), or electronic differential type clogging indicator can be installed.
• DFP filters are available with or without a bypass valve (located in filter head) so either high or low collapse pressure elements may be used.
• Multiple indicator port locations (DFP330/660/1320 only) also allow two different types of indicators to be installed into the filter.
Indicators of the same type, but with different trip pressures can also be installed. (both ports machined and plugged)
• Fatigue pressure rating equals maximum allowable working pressure rating.
