Stauff SSFT-20B Tank-Top Spin-On Filter Heads: Precision and Reliability for Hydraulic Systems
The Stauff SSFT-20B Tank-Top Spin-On Filter Heads are an advanced technical solution for return-line filtration or specific tank-top applications. Designed to deliver high performance in hydraulic circuits, these filter heads combine robust construction with versatile connection options.
Design Features and Materials
The filter head is manufactured entirely from aluminum, ensuring low weight and excellent corrosion resistance. The design is optimized for direct mounting on top of the reservoir (Tank Top Spin-On filter head), facilitating integration into existing system layouts. The structure includes a standard G1/8 port for a clogging indicator.
Performance Specifications and Fluids
These filter heads are engineered to handle flow rates of up to 200 l/min (53 US GPM) with a maximum operating pressure of 7 bar (100 PSI). Compatibility is ensured for mineral oils, covering a wide operating temperature range from -30 °C to +100 °C (-22 °F to +212 °F). Use with other fluids is possible subject to specific verification.
Filter Element Compatibility and Connections
The SSFT-20B model features a dual spigot connection system supporting G1-1/4 and 1-1/2-16 UN threads, making it specifically compatible with SFCT-57 and SFCT-58 filter elements (type A sealing profile). Technical note: The bypass valve (set at 1.7 bar / 25 PSI) is integrated into the filter element rather than the filter head; the filter element is not included with the filter head and must be ordered separately.
Ordering Code Configuration
The code SSFT-20B-1 identifies the specific configuration:
- SSFT: Spin-On filter head type.
- 20B: BSP 1-1/2 connection style (Thread Code 20B).
- 1: Drilled clogging indicator port option for return-line applications. Special versions (code 9) are available on request.
