NPS offer oil-free pistons, scrolls, water injected screws and oil-free screws. 100% oil-free compressed air for critical applications.

Applications that are sensitive to any kind of contamination in the compressed air supply require an oil-free compressor for compressed air generation. Clear examples of such applications are met in medical, dental and pharmaceutical industries, as well as in the food and beverage industries. Nevertheless, industries like chemical, electronics, oil & gas and textile use also oil-free compressors. Eventually, oil-free compressed air is a requirement for PET bottle blowing, textile processing and in farming for milking.


100% oil-free air certification & risk elimination
The oil-free compressed air generated by our compressors comply with ISO class 0 (class zero), i.e. ISO 8573-1. This means that there is no risk of any contamination caused by the compressed air production.

Small footprint & quiet operation
Particularly the CleanAIR and SpiralAIR range contain compact compressors, that require a small footprint. Moreover, due to their compressing principles and canopies they are considerably quiet in operation.

Low cost of ownership
Due to the fact that no oil has to be changed and there is no oil waste management the total cost of ownership automatically is reduced. The SpiralAIR and WisAIR compressors can adjust to demand fluctions as well as the WisAIR operates isothermally.

Ultimate quality and reliability
Since, as less moving parts and merely high quality materials are used, we ensure a long operation life time with a minimum number of service interventions.

Oil-free Scroll Compressors

The SpiralAIR 2-30 oil-free scroll compressor range provides top class performance, premium efficiency and quality. What’s more, with an oil-free compressor, you are also reducing your total cost of ownership in three ways: (1) by avoiding expensive filter replacements, (2) cutting maintenance costs for treating oil condensate and (3) the costs of extra energy needed to combat pressure drop across filters. Medium applications like milk robots in farming do not consume that much air, but may have to run continuously. Consequently, our SpiralAIR is the ideal choice.

100% Oil-free air meeting all requirements

Since no oil is used during the compressing process, logically this does not have to be filtered out and there is no risk of oil erupting in the air line work. Together with adequate air drying and filtering the compressed air we produce can be applied anywhere where pure quality compressed air is required!
