Replacement intervals depend on operating hours, system load, environmental conditions, and cleanliness requirements. In general, filter replacement should be based on differential pressure indicators or the manufacturer’s recommended service interval, rather than calendar-based maintenance alone. For critical systems, the oil cleanliness class should be monitored regularly.
A nominal filtration rating indicates the typical percentage of particles of a given size that a filter removes.
An absolute filtration rating refers to filtration efficiency measured by the Beta ratio, providing a more precise indication of filter performance. In hydraulic systems with strict cleanliness requirements, filters with a documented Beta value are recommended.
The Beta ratio is a measure of a filter’s efficiency at a specified particle size. A Beta 200 at 10 micron means that 99.5 percent of particles measuring 10 microns are removed. This is a critical parameter when selecting filter elements for systems with defined ISO cleanliness class requirements.
Filter selection depends on:
- System pressure
- Oil volume and viscosity
- Filter location within the system, such as suction, pressure, or return line
- Required cleanliness class
- Operating cycle and load conditions
We always recommend starting with the existing filter reference number or machine type to ensure accurate cross-referencing.
Yes. We supply replacement filters for most major hydraulic filter manufacturers. Provide the original OEM number or machine type, and we will identify the correct alternative for your application.
Insufficient filtration can lead to:
- Wear of pumps and valves
- Reduced system efficiency
- Increased heat generation
- Unplanned downtime
- Shortened component lifespan
Particle contamination is one of the most common causes of hydraulic system failure.
Yes. Maintaining the correct cleanliness level reduces component wear, extends oil service life, and minimizes the risk of downtime. Over time, this results in lower total operating costs.
Why is hydraulic filtration critical?
Contamination in hydraulic oil is one of the most common causes of component failure. Even microscopic particles can cause significant damage to pumps, valves, and cylinders.
Proper filtration contributes to:
- Reduced component wear
- Stable pressure and smooth system operation
- Extended oil and system service life
- Lower maintenance costs
- Fewer instances of unplanned downtime
Effective particle filtration is not merely about removing visible debris, but about maintaining controlled cleanliness levels in accordance with ISO classification standards.
Proper filtration begins with proper advisory support
Hydraulic filtration is more than simply replacing a filter. It requires an understanding of system load, operating cycles, and cleanliness requirements.
We assist with:
- System assessment and evaluation
- Recommendation of appropriate filtration grade
- Optimization of service intervals
- Reduction of overall operating costs
