What is a Vertical Shot Blaster?

Vertical Shot Blasters are a very unique piece of equipment that not everyone has had the opportunity to see in action.

They have a similar basic concept as walk behind shot blasters when it comes to how they work.  Various sized steel shot is flung at high velocity to remove rust, mil scale, paint, coatings and contaminants etc. from the steel surface its blasting. The debris is then vacuumed away through a dust extraction system and the usable shot is re-entered into the blasting process.


Vertical Shot Blasters are used for blasting vertical surfaces such as walls of industrial oil tanks or ship hulls, in a vertical or horizontal direction.

Though Vertical Shot Blasters are very efficient there are a few things to consider refining to ensure top efficiency and maximum production rates.

Some of the external factors that can affect productions rates and efficiency are:

  • The variations in the material being removed. – The thickness and toughness or amount of contaminants will affect the efficiency and production rates.
  • Efficiency of crew and operator.
  • The require cleanliness specifications for the job or requirements for any paint or coating that will be applied after the blasting.
