Hydraulic & Lubrication filters

OP

The clogging indicator OP is a visual pressure difference indicator. This type of pressure difference indicator can be mounted on all pressure filters with operating pressure up to 63 bar, if the corresponding measuring ports on the filter housing are available. With contamination of the filter element the difference between the supply pressure and the output pressure of the filter is increasing. Depending on this pressure difference but independent of the operating pressure, a visual signal is released.
