Return line filters, tank-mounted
The return filtration functions as a crucial protection stage before the fluid returns to the tank. HYDAC tank-mounted return line filters are specially designed to separate particles efficiently and ensure the long-term reliability of the overall system. This prevents damage to the pumps and enables greater system availability and reduced life cycle costs thanks to longer maintenance intervals.

Our tank mounting filters can handle flow rates of up to 15,000 litres per minute and are designed to withstand pressures of up to 25 bar. A key feature is the integrated return line check valve (depending on the product), which prevents the return line from running dry during filter element changes. The use of SUSTAINMICRON elements ensures that the initial differential pressure remains low, which is crucial during cold starts to minimise bypass activation. The compact design also allows tank breather filters to be integrated directly into the filter head, depending on the product.
