Spray guns are equipment that can spray paint or varnish using air pressure to apply it or spread it on a surface.
These guns can be used to paint on any type of surface or substrate, be it metal, wood, stone, clay (ceramics), and porcelain, plastic, glass, and textile. The spray nozzle operates by impinging high-velocity turbulent air on the surface of filaments or films of liquid, causing them to collapse to droplets with a wide range of sizes.
For this reason, spray guns are fundamental tools for any type of manufacturing industry and repainting services, since they allow industrial finishing of any of their products economically and efficiently.
Spray guns were invented in 1888 by Dr. Allen DeVilbiss in the United States. Then, his son continued to improve the invention, producing the first spray gun to use compressed air.
For the vast majority of industrial finishing jobs, it is essential to use spray guns. Simply, it is the option that is the best in price and production speed.

Sandblasting is a surface finishing process that involves the use of a powered machine — typically an air compressor as well as a sandblasting machine — to spray abrasive particles under high pressure against a surface. It’s called “sandblasting” because it blasts the surface with particles of sand. As the sand particles strike the surface, they create a smoother and more even texture. In this post, you’ll learn more about this surface finishing process and how it’s performed.
Sandblasting leverages the abrasive properties of sand to create smoother surfaces with fewer physical imperfections and flaws. It’s no secret that sand is rough and gritty. Because of these properties, it’s able to wear away at excess or unwanted material on a surface.
If you need more abrasion for a truly efficient performance our quality sand blasters come in both 10 and 20 gallon capacities.
One sandblaster we stock is the Portable Sand Blaster 10 Gallon.
· Pressurised design delivers 30% more sandblasting power than siphon units
· Provides more abrasion when you need truly efficient performance
· Equipped with nozzle and shut-off valve, pressure gauge, ceramic nozzle, filling funnel, water trap, 6in rubber wheels and canvas hood
· Tank dimensions: 12in diameter, 20in length
· Hose length: 2.5m
· Work pressure: 60~125PSI 6~25 CFM
