Compressed air treatment

4.0 Introduction

Problems caused by contaminated compressed air can lead to disastrous damage to the production equipment and to end products. The task of compressed-air treatment is to reliably remove these contaminations from the compressed-air system in order to provide the consumer with the compressed-air quality necessary for his application.

4.4 Oil-free operation

In numerous fields of application, for example in medical technology, pharmaceutics and food processing, even technically oil-free compressed air of Class 1 (0.01 mg/m³ ) is not clean enough. In these fields, oil-free compressed-air with a residual oil content of sometimes even less than 0.003 mg/m³ is required.

4.5 Condensate technology

For most condensates, the static oil-water separation turned out to be efficient and reliable.
