Buying 20 CFM Air Compressors
When buying an air compressor, it is important to make sure that you buy the correct one for your needs. Certain jobs will require the machine to be able to produce a certain amount of air, in order to make sure it can be completed without interruption.
Double Up, Trouble Down
As a rule of thumb, you should double the Cubic Feet per Minute (CFM) that is required for a tool to ensure that is works effectively and without any interruption in performance. So, where a tool states that it requires 10CFM to run, then you will need a 20CFM (FAD) compressor.
One Size Fits (almost) All
Purchasing a compressor that can run at 20CFM will be sufficient to run the vast majority of tools required for any industrial job, such as sandblasting or spray painting, provided that it has an engine power output of at least five horsepower and 80 gallons tank capacity, to ensure that the compressor runs at intervals, rather than continually. Continual operation can result in the compressor and tools overheating or burning out.
How Much & Where?
The 20 CFM compressors can usually be found on the market retailing between £600
. Clearly, this is a large investment for many small industrial firms, however, the benefits are many, as discussed above.
They are available from a number of distributors around the UK, many of which, such as Air Supplies in Leicestershire, will offer free nationwide delivery on orders over £100
