Return Line Filters

Modern hydraulic and lubrication systems now consider return line filters as indispensable components. The Pi series filters have a proven design that guarantees secure and cost-effective production processes within the fluid system. These filters perform the crucial task of collecting dirt before it is reintroduced to the hydraulic reservoir. Consequently, fewer particles find their way into the tank, leading to reduced wear on the intake pump and downstream components in the fluid circuit. Return line filters employ highly efficient filter elements, ensuring the maintenance of appropriate ISO fluid cleanliness classes. This is particularly critical in mobile applications, such as special vehicles, agricultural machinery, and construction equipment, where return line filters serve as essential working filters, contributing to defined oil cleanliness standards.
