Filter elements
Up to 1 µm: Excellent oil purity even surpasses new oil
Up to 1 µm: Excellent oil purity even surpasses new oil
The ultra-fine particle filtration up to NAS 1 (corresponds to ISO 4406: 13/10/7) provides the following benefits:
- Receives important components of the oil such as additives
- Absorbs up to 5 liters of water per element
- Keeps the oil from aging
- Works against contamination of the system
- Extends oil change intervals
- Ensures less failures (i.e. of servo valves)
3 sizes for different requirements
C-1000-filter: Maximum service life
C-750-filter: Long service life
C-500-filter: Low space requirement
6 types of filters: The proper processing for each type of oil
Types of filters | Use | Features | Application examples | NAS-purity classes | ISO 4406 purity classes |
1 | water-based fluids with viscous character | plastic content in the element | cooling lubricants, water-glycol-fluids | up to NAS 2 | 14/11/8 |
2 | low-viscosity oils (up to 40 cSt) | very high water absorption | cutting-, transformer-, forming oils, kerosene, petrol | up to NAS 1 | 13/10/7 |
3 | medium-viscosity oils (20 cSt up to 60 cSt) | high water absorption | hydraulic oil, low-viscosity engine oil | up to NAS 1 | 13/10/7 |
4 | higher viscosity oils (40 cSt up to 75 cSt) | good water absorption | engine oils, higher viscosity hydraulic oils | up to NAS 2 | 14/11/8 |
5 | fluids with a high water content, water-/ oil-emulsions | no water absorption | cooling lubricants, water based hydraulic fluids | up to NAS 2 | 14/11/8 |
6 | high viscosity oils | good water absorption | gear oils, high viscosity engine oils | up to NAS 2 | 14/11/8 |
