Schroeder's line of hydraulic filters includes: High Pressure, Medium Pressure, Tank-Mounted, Return Line, Base-Ported and Water Filters. Our expertise in filtration technology, our superior manufacturing capabilities, and our dedication to customer service and product support are the reasons we're considered "The Filter Company".

Schroeder offers a vast array of in-tank filters ranging from 15 to 450 gpm (55 to 1700 L/min). In-tank filters are a space-saving solution for filtering return line fluid when space is critical. Cap-mounted dirt alarms are available on all models. In addition, many models offer a number of other options, such as check valves that allow mounting in configurations other than vertical and diffusers which help to minimize flow turbulence.
