The gray winter months are gradually coming to an end and our fingers are already tingling to tackle new projects: We are working, cleaning and building again. With the days now getting longer and warmer, spring is the ideal time of year to give vehicles, appliances, exteriors and interiors a makeover. Whether we use compressed air, electric or cordless tools for this is not just a question of taste, but each form of drive also brings its own advantages. However, if the focus is on handiness and ergonomics, there is a clear favorite: Compressed air tools are usually lighter and more compact and are clearly superior to the other two variants in this respect.
Light, overloadable and safe - air tools for the skilled trades
Pneumatic tools are used for a wide range of craft activities. On the construction site and in interior work, they are popular tools that are regularly used for screwing, stapling and nailing. But air-powered tools are also widely used in the automotive sector, e.g. impact wrenches for loosening wheel nuts or spray guns for painting work. Since they are usually lighter than electric or cordless tools, they can even be used to reach niches and hard-to-reach places. In addition, they are much more capable of overloading, do not tend to overheat and therefore have a longer service life. When working in an environment with high humidity or with explosive, flammable substances, compressed air tools ensure a significantly higher level of safety than their electrical counterparts. For this reason, compressed air spray guns are often preferred for painting work, as the flammable paint mists in combination with electricity pose a risk of explosion that should not be underestimated.
Cleaning with compressed air – tools for private use
Air tools are not only used in the trade. They are also popular in the private sector due to their light and handy design. Blow guns, for example, are ideal for cleaning processes in the home environment, as they effectively clean even hard-to-reach areas on keyboards or radiators. Compressed air-powered sandblasters or grinders are also ideal for home use, for example to refurbish rusted fences or remove chipped paint from garden furniture. And even if no air tools are used, it makes perfect sense to have a compressor at home. You can use it to quickly and conveniently fill all leisure equipment with air, e.g. a rubber dinghy, a paddling pool or an air mattress.
Which compressor for which air tools?
When choosing the right compressor, it is crucial which compressed air tools you want to operate with it and what operating pressure is required for this. Some air tools require tanks that hold more liters and generate a lot of pressure. In addition, there are applications for which an oil-free compressor is required, such as painting work, since paint and varnish should not come into contact with oil. However, oil-free compressors often have a shorter service life.
Examples of compressed air requirements (at a working pressure of 6 bar):
|- Impact wrench||150 – 5- 00 l/min|
|- Drilling machine||200 – 500 l/min|
|- Angle grinder||300 – 800 l/min|
|- Belt grinder||150 – 400 l/min|
|- Orbital sander||250 – 400 l/min|
|- Spray gun||100 – 400 l/min|
|- Nail gun||0,3 – 1,5 l/Schuss|
|- Sandblasting gun||500 – 700 l/min|
Compressed air tools are suitable for do-it-yourselfers as well as for professional trades and industrial use. They are light and handy and can therefore be used even in hard-to-reach places. The choice of compressor depends on the air tools that you want to operate. An important parameter is the required operating pressure and, associated with this, the question of whether a boiler is needed and what dimensions it should have. Furthermore, it should be clarified in advance whether an oil-lubricated or an oil-free compressor is better suited for the specific application.
