Outdoor vapor blasting is a common method of paving, coating, sanding, staining, stamping, and painting projects. Because the techniques used can vary greatly, there are two types of outdoor wet blasting. One method is dry blasting which involves pumping pressurized air through a blasting chamber where a blasting gun shoots compressed air through the material being blasted. The other is wet blasting, in which a binder, such as Styrofoam, or a moist milling machine is used instead of compressed air to blast materials.
Both types of outdoor vapor blasting equipment are extremely useful for many different applications. Dry blasting involves a combination of water and coarse abrasive media being blasted at the same time. The water causes the abrasives to break down, creating tiny bubbles that are released into the spray. The water also cools the effect of the abrasives, removing frictional heat from the surface, reducing frosting, and stripping paint 10 times slower than conventional dry blast units.
The Vapor King is one example of a high-end model of outdoor vapor blasting equipment that uses water as well as abrasives. This particular model uses a pressurized tank that contains an anti-microbe liner which helps prevent damage to the coating applied after the water is blasted. Unlike most models that utilize pressurized tanks, this tankless model utilizes a slurry tank, which is filled with a slurry that contains baking soda and then pumped with water.
Most vapor blasters are available with a hose attachment, but the Vapor King also has a "dry blast" capability. Instead of using the tank's pressure to blast the abrasives, the "dry blast" system simply utilizes the hose's ability to push water through a nozzle. This feature allows the user to simply pump water through the hose at high pressure, thereby filling the tank with water. To control the flow of the water through the nozzle, the hose's pressure control is incorporated within the vapor blaster. This feature is ideal for spraying both liquids and non-liquids.
Another distinctive feature of the vapor honing machine is the pressure control capability. Unlike other models, the vapor king does not utilize a constant air pressure inside its tank or nozzle. Rather, the nozzle's pressure can be adjusted individually while the tank maintains a constant pressure inside the unit. If the hose is extended, it will increase the tank's pressure inside the unit. Inversely, if the hose is retracted, the system's pressure will decrease. The ability to adjust the nozzle's pressure will allow users to determine how much spray and coverage they need.
The dry dust blasting unit and the wet blasting unit are two very different systems that both serve very different purposes. Both equipment types have many advantages, but they also have limitations. For users interested in maximizing their blast coverage and efficiency, it may be a good idea to combine both systems for maximum results.
