        Reference Guide

The following information is for guidance only, to help match up and give you an idea of the largest nozzle size a compressor can cope with at a given pressure.

A common mistake most people make when setting up a blast system, whether it be a small suction cabinet or a large industrial open blast machine is thinking that their compressor produces 100 PSI and that will do. This is not the most important factor when choosing a compressor. The most important factor is the Volume of air a compressor will produce at 100 PSI. Compressors are usually rated in Cubic Feet per Minute (C.F.M.).

 
  The following chart illustrates the above.

  After using the table above to match the size of nozzle to your compressor, use the table below to match the type of nozzle liner up with the type of abrasive you are using. This should help to keep consumable costs to a minimum.
