Description
Construction Features and Materials
The SAF-05/06/07/11 Spin-On Filter Heads represent an advanced technical solution for hydraulic filtration, configured as in-line Spin-On filter heads. The construction is made of aluminum, ensuring both light weight and structural strength. The design is optimized for installation with SF-65 series filter elements (Type A sealing contour), which are not included in the standard supply of the filter head.
Performance Specifications and Operating Conditions
From a fluid dynamics standpoint, these filter heads are designed to handle different flow rates depending on the application. For return-line use, the maximum flow rate is 90 l/min (25 US GPM), while for suction-line applications the flow rate is 23 l/min (6 US GPM). The maximum supported operating pressure is 14 bar (200 PSI). For applications without a bypass valve, the maximum allowable differential pressure is 5.5 bar (80 PSI). The operating temperature range is wide, allowing use from -30 °C to +100 °C (-22 °F to +212 °F). Fluid compatibility includes standard mineral oils, with the option to request compatibility for other fluids.
Connection Configurations and Variants
The SAF series stands out for the variety of available port connection options, which define the specific model code (05, 06, 07, 11):
- Code 05: 1/2 NPT thread.
- Code 06: 3/4-16 SAE O-ring thread.
- Code 07: 3/4 NPT thread.
- Code 11: 1-1/16-12 SAE O-ring thread.
Bypass Valve and Clogging Indicator Options
The SAF-05/06/07/11 Spin-On Filter Heads provide flexibility in circuit protection through optional integrated bypass valves. Available bypass settings include:
- No bypass (Code 0).
- 0.2 bar / 3 PSI (Code B0.2).
- 0.35 bar / 5 PSI (Code B0.35).
- 1 bar / 15 PSI (Code B1.0).
- 1.7 bar / 25 PSI (Code B1.7).
In addition, the filter heads are prepared for the installation of clogging indicators (standard 1/8 NPT). Drilling options include configurations for return-line applications (Pos. 1), suction-line applications (Pos. 2), or both, ensuring optimal filter condition monitoring.
