Vapor blasting achieves similar or better results than dry abrasive blasting and hydroblasting without the collateral contamination. Using one-third the water of hydroblasting and up to 90% less grit media than dry abrasive blasting, the process operates using low hydraulic pressure means that grit particles cushioned by vapor won’t embed grit particles into substrates or force water into pores. The vapor droplets encapsulate the grit, adding mass to the particles so they are pulled by gravity to the workspace floor, rather than dispersing to nearby areas.
Dry abrasive blasting cannot be performed in high humidity or precipitation, as equipment easily becomes clogged and inoperable and performance at the nozzle is affected as well. Vapor blasting is less affected by ambient conditions, working in conditions of high temperature, high humidity and precipitation
Large equipment that requires bulky PPE, extensive shrouding, and auxiliary equipment are unwieldy in tight, complex configurations. Self-contained, compact vapor blasting equipment is a better fit in such circumstances because it requires less extensive PPE and shrouding while eliminating the need for large hoppers, dehumidifiers and huge water tanks in the work area.
Advanced vapor blasting equipment is pre-charged from the air compressor before entering the workspace and water vapor encapsulates the grit media, static/spark risks are considerably reduced, a boon for work in exposed spaces and areas with spark risks. Many models of vapor blast equipment is also designed for easy transport on flatbed trailers or the bed of a standard pickup truck and can be maneuvered into position using a standard forklift.
Process wastes in vapor blasting are easier to contain (low dispersion) and reduced in volume because vapor blasting uses only a small fraction of the grit media and water volume used by dry abrasive and hydrojetting equipment. Water and grit media storage, transportation and waste collection logistics are drastically reduced to manageable levels, even in ecologically fragile and remote locations.
Heat affected zones (HAZ) created during welding and precision parts with tight engineering tolerances are both susceptible to damage caused by heat and high velocity impact. Heat (created during the high-friction process of dry abrasive blasting) and high velocity (caused by processes employing high pressure such as dry abrasive blasting and hydrojetting) can reduce weaken, warp and reduce substrate thicknesses in these vulnerable areas. heat-causing friction.
Vapor blast equipment relies on low-pressure in combination with water vapor to create the same force of impact on cleaning, but without the risk of heat or high velocity. Water cushioned grit media can be dialed in to remove an individual layer of coating or multiple layers of coating at one time.
Advanced vapor blast equipment is compatible with vapor blasting grit media as diverse as organic, plastic, glass, engineered and steel media (virtually any media that sinks in water) to clean and decontaminate an extremely wide range of metal surfaces (from hard metals like steel to soft metals like aluminum), without risk of damage to HAZ and metal components with a narrow range of engineering tolerance.
Using the most reliable vapor blast equipment in the market lowers average surface preparation and coating project’s completion time in half by reducing the frequency of interruptions (setup,moving equipment, swtchng between machines, cleanup, etc.).
Controlling more variables generates more “wins”, lowers the investment per job (time, labor and money) for increased profit margin, and permits more and tighter project scheduling.
