Technical and Construction Features<\/strong><\/h3>\n

The SLF-02\/03\/04 Spin-On Filter Heads<\/strong> provide a reliable solution for in-line filtration in hydraulic systems. Manufactured entirely from aluminum, these filter heads ensure light weight and high strength. The design includes 1\/4-20 UNC threaded mounting holes<\/strong>, enabling easy installation in confined spaces with compact dimensions and optimized overall size. The system is designed to operate at a maximum pressure of 14 bar<\/strong> (200 PSI) and a maximum differential pressure of 5.5 bar<\/strong> (80 PSI) for applications without a bypass valve.<\/p>\n

Flow Performance and Applications<\/strong><\/h3>\n

These components are highly versatile and suitable for various system configurations. In return-line applications, the filter heads handle flow rates of up to 26 l\/min<\/strong> (7 US GPM). For suction-line use, the nominal flow rate is 7 l\/min<\/strong> (2 US GPM). Fluid compatibility is ensured for mineral oils, with the option to request configurations for other fluids. They operate efficiently within a wide temperature range from -30 \u00b0C to +100 \u00b0C<\/strong>.<\/p>\n

Available Variants and Connections<\/strong><\/h3>\n

The SLF-02\/03\/04 series stands out for the variety of available port connections, offered in both NPT and SAE O-ring thread standards to meet different installation requirements:<\/p>\n

    \n
  • SLF-02:<\/strong> Equipped with 1\/4 NPT<\/strong> connections.<\/li>\n
  • SLF-03:<\/strong> Equipped with 3\/8 NPT<\/strong> connections.<\/li>\n
  • SLF-04:<\/strong> Equipped with 9\/16-18 SAE<\/strong> connections.<\/li>\n<\/ul>\n

    The filter element connection is a standardized 3\/4-16 UNF<\/strong>.<\/p>\n

    Filter Element Compatibility and Accessories<\/strong><\/h3>\n

    The filter heads are specifically designed for use with SF-63 series filter elements<\/strong> and elements with a Type A sealing contour. Please note that the filter element is not included in the standard supply. For filter condition monitoring, the heads feature ports for clogging indicators with 1\/8 NPT<\/strong> threads. Indicator positioning depends on the application: Position 1 for return lines and Position 2 for suction lines, ensuring accurate monitoring under all operating conditions.<\/p>\n
