Since ancient times, man has been using metal for one purpose or another.. Spears, armor, chains, axes, hammers and other human inventions were always made from this element. By and large, today, little has changed with us. We constantly deal with metal products: cars, Appliances, bridge supports, railroad rails, Trains, Aircraft - everything consists of metal. Yes, even our buildings have metal reinforcement inside, which creates an even stronger connection with concrete.
The prevalence of such elements is very simple to explain: metals have a whole set of properties, which are important to us. At first, they are (Most) Very strong, Consequently, able to withstand serious loads on themselves. Secondly, They carry out electric current well, Thanks to our homes there is always light. Thirdly, most metals have high plasticity. This indicates, that the metal can be given absolutely any shape. However, there are drawbacks: metals are very well oxidized. What can lead to its destruction. From this very often our cars rust.
But there are specialized devices, allowing metals from harmful formations: oxaline, rust, corrosion, etc.. Such devices include sandblasting equipment. here Sandbrown equipment is presented in a fairly large amount. How it works? The compressor pumps air, which passes through the sand bowl. Through a special pistol-spray, the resulting mixture under high pressure comes out. The speed of the mixture can reach order 40 meters per second. Thanks to this, sand particles simply knock down the formation from the metal, Leaving him "clean". Thus, you can prepare a metal surface for painting, putty or soil. 
A big plus of the use of sandblasting equipment is time saving, spent on surface processing. Modern sandblasting machines can process before 30 square meters of surface per hour, which is a very high indicator. Just imagine, how much time would, to produce similar ways in the usual way, manually. Likely, For this it would be necessary to spend more than one hour. Naturally, Sandbrown equipment differs as in performance, and in power. Important, what exactly the compressor costs, since it is he who is responsible for the pressure in the system.
