What size nozzle do I need?
The nozzle determines how large media you can use, and how much work you can do in a given period of time.
There are two main determining factors when selecting a nozzle. First and foremost the amount CFMs (cubic feet per minute) your air compressor will produce. Secondly, the size of the media. Media come in a wide range of sizes. Media manufacture will be able to offer grit and nozzle size recommendations to suit your application.
Using the chart below as a reference guide, you can determine which nozzle your air compressor will handle. Once you determined the nozzle size, you can then select a media to match the diameter of the nozzle opening (nozzle size).
*A note about the Compressor Nozzle Match Table: The table provides a generalized guide for matching compressors and nozzles. While it is fairly reliable, it is NOT set in stone. There are just too many variables: media choice, compressor hose length, blast hose length, environmental conditions, and the actual compressor CFM. It’s always a good idea to have more airflow (CFM) than recommended, extra is better.
