Introduction Description Features and Benefits OFP filters are designed for pressure line applications and are suitable for in-line installation. OFMT filters are designed for return lines and are installed semi-immersed in a reservoir. OFRT filters are also designed for return lines and are installed semi-immersed or totally immersed in a reservoir. All remove particulate contaminants from the fluid, thus improving performance and reliability of system components while extending their service life. D High efficiency filter elements with superior dirt-holding capacity. D Excellent pressure...

Contamination Control The Systemic Approach to Contamination Control For a hydraulic or oil lubricated machine, the development of a target cleanliness level and the plan to achieve it is as much a part of system design as the selection of the pump, valves, actuators or bearings. Proper selection and placement of contamination control devices in a system to attain the targeted cleanliness eliminates up to 80% of hydraulic system failures. Additionally, the system cleanliness approach assures the user of the hydraulic system a cost effective approach to contamination control that allows the...
