The downloadable PDF chart indicates the airflow required for each of the airjet and nozzle options. Please use this information as a guide when specifying the compressed air supply to the blast system. Note that the compressed air supply should be capable of providing at least 50% more air volume than is required when the nozzle is new. This will ensure that the nozzle will continue to function efficiently even when worn.

There is also available a separate leaflet that shows a photographic guide of the various Guyson nozzles and airjets in case you don't know which version you have or want, and that can be downloaded here
