õlituseta

Õlituseta is an Estonian term that translates to "without oil" or "oil-free." It is primarily used in technical contexts to describe mechanical systems, processes, or components that do not require lubrication by oil. This can apply to a wide range of applications, from industrial machinery to food processing equipment and even certain types of coatings.

The concept of oil-free operation is often driven by the need to avoid contamination. In industries such as pharmaceuticals, food and beverage, and semiconductor manufacturing, the presence of oil can compromise the purity and safety of the final product. Therefore, equipment designed for these sectors is frequently engineered to function without any oil lubrication.

There are various technologies that enable oil-free operation. These can include the use of self-lubricating materials, such as certain plastics or composite materials that have low friction properties. Another approach involves employing alternative lubrication methods, like dry lubrication with solid lubricants or utilizing air as a lubricant in some specialized applications. In the context of compressors, "oil-free" specifically refers to compressors where the compression chamber itself is not lubricated with oil, preventing oil from entering the compressed air stream. This distinction is crucial for applications where clean air is a requirement.
