Oil free Piston compressors
In many sectors of industry, high quality and extremely clean air is required. Dust, humidity and oil must be removed from the compressed air in order to meet more stringent requirements. Dust and humidity can be removed downstream by means of compressed air treatment. This is an effective and popular method.
Competent advice will help you find the right method, ensuring the safest and most cost efficient means of generating oil free compressed air, for your application.
The most direct method of generating oil free compressed air is to opt for an oil free compressor. Oil free piston compressors operate with no oil at all. Bearings are filled with grease and encapsulated. When there is no oil, no oil can penetrate into the compressed air. The result in either case is zero contamination.
Where no oil free compressors are used or only a small amount of the compressed air produced has to be treated in a standalone system, it is recommended that a retrofit installation be put in place. Microfilters in combination with active charcoal filters or active charcoal adsorbers serve to remove liquid and vaporous oil from the compressed air. The result is oil free compressed air with a residual oil content which may even be below that of the ambient air. If properly serviced and maintained, this type of generation of oil free compressed air is able to fulfil many quality requirements.
