Filtering performance
ISO qualification, according to the WEARCHECK GmbH, Brandenburg, 28 September 1993, laboratory report
No 1101/13535/36 |
Water absorption, high filtering power of solid particles down to 0.1 m m; medium range: 1 m m.
TRABOLD filter corresponds to the prescriptions of the ISO/DIS 4406 NORM 11/8. standard. Achieving this qualification, the filter can operate at a cleaner output of the average commercial quality. The water take-up capacity of the grade10 filter cartridge under operational conditions is 60 - 100 g. The water absorption of larger filters varies in proportion with the volume. |
Mode of filtering |
High-power filtering with radial and axial mode; both flow directions combined; using the whole filter cartridge, the filter volume is minimized. |
Inlet pressure |
Minimum pressure = 0.5 bar, maximum pressure - filter cartridge is compressed only slightly even at 400 bar. Filter case can be loaded steadily up to 20 bar, and max. 30 bar pressure peaks are allowed. |
Pressure reduction in engine |
According to tests, the pressure in the engine does not decrease because the oil pump has adequate reserve capacity. |
Changing the filter cartridge |
In engines: every 10,000 - 30,000 miles, or equivalent operation time; in hydraulic or oil-heater systems: with a frequency depending on the equipment and contamination. |
Time of filter cartridge change |
5 - 10 minutes. |
