How do centrifugal air compressors work?
The centrifugal air compressor is a dynamic compressor which depends on transfer of energy from a rotating impeller to the air.
Centrifugal compressors produce high-pressure discharge by converting angular momentum imparted by the rotating impeller (dynamic displacement). In order to do this efficiently, centrifugal compressors rotate at higher speeds than the other types of compressors. These types of compressors are also designed for higher capacity because flow through the compressor is continuous.
Adjusting the inlet guide vanes is the most common method to control capacity of a centrifugal compressor. By closing the guide vanes, volumetric flows and capacity are reduced.
The centrifugal air compressor is an oil free compressor by design. The oil lubricated running gear is separated from the air by shaft seals and atmospheric vents.
Centrifugal air compressors are commonly used as base load compressors for large volume applications.

Buying a new air compressor? Do you really understand the compressed air requirements of your plant? Do you know how much air your equipment consumes and at what pressure? Are you aware that the single biggest cost associated with owning and operating an air compressor system will be the electricity costs required to run it?
Over a typical 10 year air compressor life cycle, the cost of energy will account for around 75%-80% of total costs, dwarfing the initial costs associated with equipment purchase, installation and maintenance.
Independent air compressor sales advice
Before you contact the usual air compressor dealers, consider getting your current or proposed new system properly appraised, so that you can be sure you are buying what you actually need as opposed to what you are being sold.
At Compressed Air Technology, we make the effort to actually measure and monitor your system BEFORE you proceed with a high value purchase, ensuring the lifetime ownership costs are kept to a minimum.
As an independent operator, not tied to any particular brand, we have access to a huge range of premium quality equipment that is selected to ensure compressed air is supplied to your plant at the correct volume, pressure and quality, with a heavy focus on reliability.
We also supply a range of piping systems including aluminium, copper, stainless steel, HDPE and many more

Centrifugal air compressor system design
Too often we see the wrong compressors installed for the application. A great deal on a larger compressor may look appealing initially, but seldom does anyone point out the additional electrical costs incurred to run it over the ten or so years it will be in operation.
Our approach tends to differ from that of a traditional compressor dealer, we believe in spending time with our clients to get to know the true compressed air requirements so that the correct equipment can be evaluated and selected accordingly.
We take a similar approach to designing your piping and distribution systems. Remember, a compressed air system is only as efficient as its installation. We often hear clients complain they are ‘running out of air’, when the fact is their compressors are perfectly cable of supplying their processes, but restrictions in piping and poor design are leading to pressure drop and subsequent equipment malfunction.

Centrifugal air compressor efficiency audits
Have you considered how much your compressed air system costs to run? Many business owners haven’t and it’s a common misconception that compressed air is free. It’s only air, right? Wrong!
Compressed air is expensive!
Did you know that compressed air is one of the most expensive forms of energy used in industry today?
Often termed the ‘Fourth Utility’, compressed air is just as important to some businesses as electricity, water or gas. It is also very expensive to produce when you consider it takes approximately 7hp of electrical power to produce just 1hp of compressed air power…
10-15% of all industrial electricity is used to general compressed air.
