The OMT 90910-175-042, also known as model STR 175-4-S-G-M-M90, is a high-quality immersed suction strainer designed for direct installation onto the suction lines of hydraulic pumps. Its primary function is to protect the pump from coarse contaminants and foreign particles that may be present in the reservoir fluid. This model is constructed with a durable 90-micron wire mesh filtering element and features an integrated magnetic core. The magnetic core effectively captures and retains fine ferrous particles, providing an extra layer of protection and extending the life of the pump and other hydraulic components.
