PLF Series Pressure Line Filter

PLF Series Pressure Line Filter

Pressure line filters are an essential part of most hydraulic systems, located downstream from the system pump and designed to handle the system pressure and flow rate. They are available in a variety of sizes and types, including the PLF series. Pressure line filters are used to protect hydraulic systems from wear and tear, as well as to reduce the risk of hydraulic system failure.


PLF series filter is of high-pressure type and used in the pressure line of the hydraulic system. It can remove all the contaminants from the hydraulic system. The element of this series is made of glass fiber. it has high efficiency and filtration, large dirt capacity, and low initial pressure drop. The beta ratio is over 200.

It has two pieces of protection equipment which are by-pass valve and contamination indicator. The indicator will act when the pressure drop across the element attains adjustable pressure. The element should be cleaned or changed in time. Compare to other filters, this kind of filter is designed in small size. It can be used in different pressure levels and can be easily installed and the filter element also can be easily changed.
