In the field of Air-Compressors, two types of compressors are being used : - Oil-flooded or Oil-injected Air-Compressors (Oil-injected Screw, Oil-flooded vane compressors) - Oil-free Compressors (Oil-free Screw, Turbo Compressors, Piston Compressors, Water Injected Screw and Oil-free Scroll Compressors, Membrane Compressors). The Oil-flooded Air-compressors leave 2-10ppm of oil in the...
Vision and believes
Vision and Believes by Chris Lybaert Climate change is all over the news. Horrifying stories and images are shown by environmental activist almost daily. Documentaries shows how Ice caps are melting. Floodings, draught, hurricanes are violently distroying nature and humans life. Our youth, for who life still has to...

42 Can an Oil-free installation be more cost effective than an Oil-lub installation ?
The only reason why Oil-lubricated compressors exist, is the initial cost of an Oil-lubricated compressor is cheaper. Yes I use the word cheaper and not lower cost ! Many users, when they need to select a new compressor, they are shocked about the high purchase price and the difference between...
41 Can your Oil-free Air compressor run a marathon in years ?
Running a marathon is for most people a physical challenge. Running 42 kilometers in one go is not for everybody. Your body needs to be adapted, wel trained in order to be able to run that far. Air-compressors are not only designed for a certain capacity, but also for a...
40. Are you saving 30% on your Oil-free Compressed Air installation ?
Good marketing is convincing you that something is better than others. This is common practice throughout industry ! So have we been told that drinking cow milk and eating white bread is healthy. While in the meantime, everybody starts to realise that the opposite is true. More and more it...

39. Is an Oil-free screw compressor a volumetric or dynamic compressor ?
To compress air, two compression principles are defined, either volumetric compression either dynamic compression. The Volumetric compression reduces a volume to a smaller volume, and the ratio of the two volumes defines the compression ratio. This is the working principle of a reciprocating air-compressor. During compression, the compressor chamber is...
