FST
FST
The document discusses the FST series of filters developed by FAI FILTRI, designed to efficiently control contamination levels in hydraulic fluids and fuels. These filters are suitable for various applications, including earthworks machinery and agricultural machines, and can handle pressure peaks up to 12 bar.
Key Features
- Easy replacement of clogged filters through a quick and clean procedure.
- Supports flow rates up to 300 l/min.
- Equipped with an anti-emptying membrane and optional by-pass valve.
- Spin-on cartridges with new-generation 'A' filtering media for high performance.
- Absolute filtration power of 3, 6, 10, 25 microns.
- Resistant to deformation and strain, preventing contaminant release.
Technical Specifications
- Materials: Galvanized stamped plate flange, sintered and painted sheet steel vessel, perforated supporting pipes, and aluminum casted head.
- Operating pressure: 12 bar.
- Impulse test: ISO 3724 compliance.
- Filtering elements: 'P', 'A', and 'M' types with varying micron ratings.
- Retention power: Complies with ISO 4572 Multi-pass test method.
International Standards
- Complies with ISO 4406 contamination codes and NAS 1638 corresponding class.
- Suggested filtration application fields range from high accuracy servo-plants to low-pressure plants.
Additional Features
- By-pass valve with a differential pressure of 2 bar ±10%.
- Gaskets available in Buna-N and Viton types.
- Operating temperature range: -25°C to +110°C.
- Flow rate up to 200 l/min.
- Indicators include VR Type pressure gauge and L1 Type manostat.
Pressure Drop
- Calculated in compliance with ISO 3968.
- Valid for mineral oils with specific density and viscosity.
Dimensional Information
- Detailed dimensions provided for different FST models.
Functional Diagram
- Illustrates the flow of return lines through the filter elements.
Order Code
- Provides a structured format for ordering specific filter types and configurations.
Catalog excerpts
Many years of in-field experience have shown the necessity of more and more efficient controls on the contamination level of hydraulic fluids and fuels. With this goal uppermost in its mind, and thanks to sophisticated design patterns and the use of cutting-edge materials and technologies, FAI FILTRI has engineered the FST series of complete filters , in different models and sizes, designed to meet a wide array of filtration and operating requirements, in order to allow a more effective control of contamination levels in hydraulic, lubricating, engine circuits, etc. FST filters provide a valid...
