Machine Life Extension Calculator

ISO 4406 Oil Cleanliness Calculator

Machine Life Extension Calculator

Estimate potential machine life extension by improving lubricant cleanliness according to ISO 4406 particle count codes.

ISO 4406 Format 4 µm(c) / 6 µm(c) / 14 µm(c)

Example 20/18/15

Result Colours Red = low, Orange = medium, Green = high

Machine Type

Current Oil Cleanliness ISO 4406: 4 µm(c) / 6 µm(c) / 14 µm(c)

New Target Oil Cleanliness ISO 4406: 4 µm(c) / 6 µm(c) / 14 µm(c)

Estimated Life Extension —

Select a machine type, current ISO 4406 cleanliness code and new cleaner target.
