Pressure blasting vs. Injector blasting

This article explains the differences between pressure blasting and injector blasting. Find out in which cases you should use which blasting technique and what you need to consider.

When it comes to finding the right blasting equipment for abrasive blasting ( commonly known as sandblasting ), from the right blast cabinet  to the right blast nozzle , the question always has to be asked which blasting system or blasting technology is suitable for the job to be done. There is a significant difference between pressure blasting and injector blasting.

The answer to the question of whether pressure blasting or injector blasting is the right choice is determined by the degree of surface contamination and the amount of compressed air available. In general, the pressure blasting process offers higher performance, allowing more surface area to be processed and/or more difficult impurities to be efficiently cleaned.

However, if you are limited in the amount of compressed air available, the injector system is a very good alternative that allows you to blast workpieces even when there is little air available. It is therefore considered a cost-effective blasting system, although this is only relative in terms of working time and efficiency (an overview of the air required can be found in the article on compressed air requirements). 

The injector process also has special fields of application, where this blasting technology has an advantage over the pressure blasting process. In addition to the reasons already mentioned, the injector system is also extremely portable thanks to its easy setup. A Clemco Injector Power Gun , for example, only requires a compressed air line and a bag of abrasive, from which the blasting gun sucks the abrasive directly via vacuum and generates an abrasive compressed air jet. 
In addition, the injector blasting process is also suitable for surfaces that would not withstand the pressure of the pressure blasting process, e.g. thin aluminum or where only a small amount of surface removal is necessary or intended.
