Overview and Applications<\/strong><\/h3>\n

The Stauff SFZ Pressure Filter<\/strong> series is engineered for hydraulic applications requiring sandwich plate mounting on manifold blocks. These components are designed to operate in high-pressure systems, ensuring a maximum operating pressure of 315 bar (4560 PSI) and a minimum burst pressure of 945 bar (13,705 PSI), thus providing a high structural safety factor.<\/p>\n

Design Specifications and Materials<\/strong><\/h3>\n

Robustness is a core feature of the SFZ series. The filter head is manufactured from free-cutting steel, while the bowl is made of cold-drawn steel. To ensure optimal sealing, the filters are equipped with O-rings available in NBR (Buna-N\u00ae), FKM (Viton\u00ae), or EPDM, combined with PTFE backup rings. The connection interface complies with ISO 4401-03-02-0-05 NG6 \/ DIN 24340-A6 \/ Cetop R 35 H standards.<\/p>\n

Filter Elements and Media<\/strong><\/h3>\n

SFZ filters use Stauff SE series filter elements, offering high dirt-holding capacity and long service life. Various filter media can be selected depending on the application:<\/p>\n

    \n
  • Inorganic glass fiber (Codes G and H):<\/strong> Available with collapse pressure of 25 bar (G) or 210 bar (H) for fine filtration (3, 5, 10, 20 \u00b5m).<\/li>\n
  • Stainless steel fiber (Code M):<\/strong> High collapse resistance (210 bar) for fine filtration.<\/li>\n
  • Stainless steel wire mesh (Code S):<\/strong> Collapse pressure of 30 bar for coarse filtration (25, 50, 100, 200 \u00b5m).<\/li>\n<\/ul>\n

    Indicators and Safety Devices<\/strong><\/h3>\n

    For monitoring the condition of the filter element, visual, electrical, or visual-electrical clogging indicators are available, with a standard actuation pressure of 5 bar. It is important to note that the filter element is not protected by an internal bypass; therefore, the hydraulic system must be designed with sufficient means to protect the element from overpressure. Available options also include a \u201cThermostop\u201d function to inhibit the electrical signal at low temperatures.<\/p>\n
