Schroeder DD-3 Hydraulic Filter

Schroeder DD3 is a double‑length hydraulic cartridge filter element from the DD series, engineered for hydraulic and lubrication circuits and compatible with Schroeder filter housings that use a seal-type connection. It uses E Media (Cellulose) to deliver a 3 µm nominal filtration with a Beta Ratio of 200 and an efficiency around 99.5%, helping remove fine contaminants before they reach pumps and valves. The element is 9.7 inches tall, with an outer diameter of 2.6 inches and an inner diameter of 1.1 inches, designed as a double‑length replacement for Schroeder DD housings. The Buna seal and seal‑type connection ensure a reliable fit in typical Schroeder filter systems. Operating temperature ranges listed on supplier pages show a maximum of 107 and a minimum of -29, indicating suitability for a broad range of hydraulic fluids and service conditions. This DD3 element is categorized as a hydraulic and lube filter element and is intended to be used with Schroeder filter housings designed for the DD series, making it a straightforward upgrade or replacement in compatible equipment. With its cellulose media and compact, high‑efficiency construction, the DD3 provides strong particulate removal while fitting standard DD‑series housings in industrial or mobile hydraulic applications that require precise micron‑level filtration.
