Abrasive Blasting

Vapour abrasive blasting (also known as wet abrasive blasting) removes coatings, contaminants, corrosion and residues from hard surfaces. It's similar to dry blasting, except that the blast media is moistened prior to impacting the surface, reducing dust significantly and also reducing the amount of water used when compared to traditional wet blasting.

How wet abrasive blasting works

How Does Wet Abrasive Blasting Work?

Water and abrasive are combined in a pot under water pressure and then precisely metered into the airflow. When wet abrasive impacts a surface, the additional water weighs the particles down and creates a “dustless” effect.

Since EcoQuip 2 uses less water than slurry or other water-based technologies, pools of water aren't left behind so there is less need to worry about toxic run-off.

Understanding "Dust-free" or "Dustless" Blasting

True Dustless Blasting is Impossible

Some might claim that their products are "dustless" or "dust-free," but the reality is there is no such thing.

Sure, using a wet abrasive blasting machine will cut down on the plume of dust you get from dry blasting, but you're also left with a puddle of water. Make sure you understand the facts around dustless blasting.

With Graco's EcoQuip 2 Vapour Abrasive blast equipment, you will see up to 92% dust suppression over dry blasting without the wet, slurry mess you get from traditional wet abrasive blasters.
