The difference between free jet blasting and recovery blasting

Reading time : 1 minute and 30 seconds

Sandblasting is a process of high importance in many production sectors, both in the field of carpentry and surface cleaning. There are different types of machinery used to perform this treatment, including free-jet and recovery sandblasting machines. Knowledge of the differences between these machines is essential for those who deal with professional sandblasting. In this article, the advantages of both types of sandblasting machines will be examined, so as to facilitate the choice of the most suitable machinery for specific needs.

Advantages of free-jet blasting


Among the advantages of the free-jet sandblasting machine, the possibility of using cheaper abrasives and aggregates is evident. In addition, it is possible to monitor the surface being treated more easily thanks to greater visibility, as well as to adjust the distance between the sandblasting machine nozzle and the surface to be treated according to the desired incidence during the sandblasting phases.


Advantages of the recovery sandblasting machine with suction gun

The recovery sandblasting machine with suction gun is a type of sandblasting machine that boasts a gun equipped with a suction system, which guarantees the recovery and recycling of the abrasive used, then separating it from the dust.

The main advantage, without a doubt, is to have a zero environmental impact. Thanks to this feature, it is possible to carry out sandblasting operations even in closed environments, in complete safety, even for those who are in the close vicinity of the intervention. In addition, this sandblasting machine allows you to reduce operating costs, since the abrasive is recycled.



In summary, free-jet sandblasting machines and recovery sandblasting machines with suction gun have different characteristics that define their uses and effectiveness in different areas of application. The choice between the two depends on the specific needs of the user. However, it is equally important to take into account the environmental impact and running costs.
