Shot blasting is an essential process in the manufacturing world. It’s used to remove coatings, glue, and other substances from various materials. Despite its importance, it has been largely neglected by businesses in recent years.

This is due in part to the fact that CFM (Cubic Feet per Minute) requirements for shot blasting have not kept pace with technology developments. In this blog post, we will provide a guide on what CFM you need for shot blasting. We will also highlight some of the new technologies and how they will require different CFM amounts. Finally, we will provide tips on how to find the right shot blasting contractor for your needs.

What is CFM?

CFM stands for cubic feet per minute. When you blast a material, the amount of air flow is important in order to create the desired effect. The higher the CFM, the faster the air will flow and produce more pressure. A shot blasting machine manufacturer typically lists CFM as one of the specifications on their machines.

How to find the right shot blasting contractor?

When looking for a shot blasting contractor, it is important to do your research. There are many reputable companies out there, so it is important to find one that you trust. Ask around, check online reviews, and speak with friends who have used contractors in the past. Once you have a few contractors in mind, contact them to get a quote for the work you need done.

Shot blasting refers to the use of high-velocity projectiles to remove surface contaminants from objects. It can be used for a variety of applications, including: corrosion control on surfaces such as pipelines and tanks; removal of paint and other coatings; and abatement of moss, lichen, and soft soil.

There are several factors that affect the performance of shot blasting. These include the type of shot used, the gun barrel length and caliber, the target material, and the blast angle.

– The type of shot used is generally based on the intended application. For example, ball shots are most often used for abatement purposes because they create smaller holes than cone or tungsten shots. However, ball shots have less impact energy than cone or tungsten shots and may not be suitable for some applications.

– The gun barrel length and caliber affects the speed and strength of the blast wave. A longer barrel results in a higher velocity shot wave, which can penetrate more deeply into the target material. A larger caliber also results in a greater impact energy, which can more easily break through tough materials.

– The target material affects both how much damage is done to the surface by the blast wave and how easy it is to clean up afterward. Materials that resist fragmentation (such as concrete) tend to take more damage from a blast wave than materials that break easily (like wood). Additionally, harder targets require shorter barrels or larger calibers in order to generate enough energy to break them down.

– The blast angle affects how much of the projectile is exposed to the air and thus how quickly it disperses. A steep blast angle creates a larger blast wave that pierces more deeply into the target material. Shorter, wider barrels are often used with a shallow blast angle to reduce recoil and increase accuracy.


Shot blasting is a process that uses high-pressure air to remove coatings, lacquers and other substrates from objects. In order to get the best results, you’ll need to know how much CFM (cubic feet per minute) your machine requires. This guide will help you find out. By understanding how much CFM your shot blasting machine needs, you can ensure that the process is performed correctly and with optimal results.
