Why use Wet Vapor Blasting Systems?
Wet vapor abrasive blasting reduces the dust generated by dry blasting but can still remove coatings and corrosion residue and create a clean, profiled surface.
The advantage of wet blasting technologies is the ability to blast without dust when containment is too costly or not viable.
You have precise control of the air, grit, and water flow to lock in optimal blasting performance with efficient grit and water consumption. Once optimal flow parameters are set, switching between normal blasting settings and lower air pressure for wash down and blow off is consistent, fast, and easy.
Blasting pressures are able to be set between 10 and 150 psi.
Common issues with Wet Vapor Blasting Systems
Wet blasting systems from BlastOne use mist blasting technology, which injects water into the metering valve after the abrasive has been metered. Many of the alternative systems use slurry blasting which
Mist Blast technology overcomes two common problems of other wet blast technologies: inadequate water flow control and inadequate abrasive flow control. Changing grit size accentuates this problem. With wet abrasive in the pot i.e., slurry blasting, it is difficult to control the water and abrasive flow. This is because the feed water needs pressurizing to push the abrasive out. The larger the abrasive particle size, the larger the problem is. The coarser the abrasive, the larger the gaps between the abrasive particles, i.e., the abrasive holds more water. This requires a large amount of water to get flow. Typically, when using a Slurry Blasting system, a fine abrasive is used to give more control of the abrasive and water volumes.
Important considerations when choosing the right Wet Vapor Blasting Systems
The most important consideration when selecting a wet blast is which technology to use, slurry blasting or mist blasting. Mist blasting has some distinct advantages.
Mist Blaster technology controls abrasive flow better and reduces water consumption. The two key reasons you want to reduce water consumption are:
- Wet abrasive is always harder to dispose of than dry.
- Large volumes of water create a liquid waste disposal issue, which can be more complex than dry waste disposal.
With Mist Blast technology, you can use less than one pint of water and still get a high production abrasive blasting rate with a 90% or greater dust reduction.
