Savings potential with oil-free air compressors

The potential savings over the years can be enormous. As an example, one customer’s data shows that the cumulative maintenance costs of our oil-lubricated compressors over a period of 20 years and 146 units in their fleet resulted in a potential savings of 2.95 million Euros, equivalent with 86%, when compared to the oil-lubricated air compressors. And the positive impact on the environment, is always priceless.
