SCHROEDER

SCHROEDER hydraulic filter elements are available in a range of micron ratings, including 3, 5, 10, and 25 microns, as seen in models like the SBF-9600-8Z3B (3 micron), SBF-8300-16Z5V (5 micron), SBF-9020-4Z10B (10 micron), and SBF-8900-13Z25B (25 micron). These ratings indicate the particle size at which the filter achieves a specified efficiency, typically with a Beta ratio of 1000 or higher for the rated micron size. The choice of micron rating depends on the system's cleanliness requirements, such as ISO 4406 codes, and the sensitivity of components like servo valves or pumps.

Yes, SCHROEDER filter elements with fiberglass media are compatible with a wide range of hydraulic fluids, including mineral oils, synthetic esters, polyalphaolefins (PAO), and water-glycol mixtures. The fiberglass media is chemically resistant and does not degrade in the presence of common additives or high temperatures up to 120°C. However, for specific fluid types, it is recommended to verify compatibility with the manufacturer's technical data, as some fluids may require special seal materials (e.g., FKM or EPDM) that are available on request.

SCHROEDER cartridge filter elements are designed for use in filter housings that can withstand operating pressures up to 420 bar (approximately 6090 psi) for high-pressure applications, such as those in the SBF-9600 series. For return-line and suction filters, the pressure rating is typically lower, around 10 to 25 bar. The element itself does not have a pressure rating independent of the housing; the assembly's pressure capability is determined by the housing design and material (e.g., steel or aluminum). Always check the housing specifications for the maximum allowable working pressure.

SCHROEDER filter elements often have multiple cross-reference numbers, including the manufacturer's own part number (e.g., SBF-8900-13Z25B) and common OEM numbers like HC8900FKT13H or 1.08.13D25BN. To cross-reference, compare the key specifications: micron rating, media type (fiberglass), dimensions (outer diameter, inner diameter, length), and connection type (e.g., thread size or flange). 3G Electric provides cross-reference support for these elements, and you can use the manufacturer part number or OEM number to verify compatibility with your existing filter housing.

The service life of a SCHROEDER hydraulic filter element depends on the system's contamination level, flow rate, and fluid viscosity. Under normal operating conditions with moderate contamination, a 10-micron fiberglass element may last between 2000 and 4000 hours before reaching its differential pressure limit (typically 2 to 5 bar for return-line filters). High dirt-holding capacity designs, such as those in the SBF series, can extend service life. Regular monitoring of differential pressure gauges or clogging indicators is recommended to determine replacement intervals.
