Tank mounted return filters
Return filters on the reservoir catch the wear particles the system makes before the oil goes back to the pump.
Industrial power units
Return and pressure filters on presses, machine tools, plastics machines and test rigs take this element. A fresh element keeps pumps and valves at the cleanliness they were designed for.
Mobile and marine hydraulics
The same element sizes run on cranes, winches, deck machinery and mobile plant, where contamination is the main cause of pump and valve wear.

Sites with several filters on the same element can hold stock for scheduled changes at a lower price than buying OEM every time.
