What Are Spin-On Filters?
Spin-On Filters are compact hydraulic filter assemblies consisting of an aluminum head and one or two spin-on filter elements, typically installed inline for easy maintenance. They act as safety and process filters that protect valves, pumps, cylinders, and complete hydraulic circuits from contamination, ensuring compliance with ISO 4406 hydraulic cleanliness standards.
Why Choose Our Hydraulic Spin-On Filters?
The hydraulic spin-on filters we supply are engineered through years of testing and continuous research into filter media and mechanical performance. This advanced design ensures superior oil filtration and consistent performance across both hydraulic and lube oil systems. Key advantages include:
- Lower pressure loss during operation
- Improved filtration efficiency and flow stability
- Extended equipment life and enhanced reliability
- High contaminant retention capacity for longer service intervals
Result: Consistent filtration performance, reduced maintenance downtime, and extended service life for hydraulic systems and lube oil circuits.
Spin-On filter elements feature an absolute filtration rating made from inorganic impregnated and resin-bonded inert micro-fibres. This creates a compact filtering core that resists deformation, prevents contaminant release, and improves overall filtration performance. Each spin-on filter element is engineered for durability and high dirt-holding capacity, ensuring maximum system reliability.
