Buying a new car is always an exciting moment. Although you need to be looking at fuel efficiency and hybrid cars, emotionally, we like to have a large engine in the car. A 6-cyl or 8 cylinder will last much longer than a fast running 4 or even 3 cylinder. Trend is however...

The Reciprocating compressor or the Piston compressor, is one of the simplest and oldest way of compressing air. Before 1960, the piston compressor was the standard. They were used for all size, from small air compressors to large sizes, from low pressure to high pressure. The reliability and the maintenance intervals...

During my visit to Asia, I was confronted with again the daily reality. We all talk about climate change and the disaster it is becoming. Indeed, no explanation needed to illustrate the floodings, the melting of the Ice caps etc… At the same time, in the Compressed Air world, little changes....

During my recent interactions with customers and Energy consultants globally, my observations have been shocking. The reality is that the industry outsources more and more non-core related activities. The internal technical departments of companies have been squeezed to the minimum and the suppliers of equipment need to make offers to the...

Many users of compressed air in segments which needs ISO 8753 class 1 air quality, are still considering Oil-flooded compressors instead of Oil-free compressors. Injecting oil to compress air to seperate it again from the air, is an absurd idea. However, it is still a very common practice. The only reason is because...

After my article on the service factor used in Screw air-compressors, it is confirmed that there is a lot of misunderstanding and confusion on the topic of Service Factor. Service Factor when it is used and why it is used. Therefor, I like to explain by the history of the Screw...

When you want to buy a compressor, you will define the flow and the pressure you require for your factory. Then you will check the compressor manufacturer catalogue on which model you will need. Then you compare the kW/HP size of the different manufacturers. What they don't tell you is that : the...

Are there other compressor principles besides the Oilfree-screw and the Centrifugal providing Oil-free Compressed air. The question often is raised, what about Scroll compressor, Water injected compressor, Oil-free industrial compressors and other innovations…? Oil-free Compressed Air can be obtained with other compressor principles but all of them have their application range....

Recips are being used in many applications and are so widely spread, that one recip is not the other one. First of all, the reciprocating technology is rewarded by the automotive industry as being the best technology when it comes to fuel efficiency ? In the 70ies during the oil...

A dry screw air-compressor is like a recipricating air-compressor but without segments. If the compression speed is low, most of the air would leak back to the inlet. By running it faster, the time to leak back is shorter. Dry screws are not having any sealant, like other displacement compressors. An oil-flooded screw compressor...
