Silicone guns, for painting or screwing, drilling machines – these are just some of the pneumatic tools that can make your life easier. Find out in this article what other useful tools you can combine with a good compressor, to save money, time and effort, and to easily and quickly complete all kinds of projects.
As the name suggests, the role of such a device is to compress the air inside a tank, bringing it to a higher pressure than in the atmosphere. When the container is full, the compressor stops and the air is kept inside until it is needed. Pressurized air is used to operate a variety of low, medium or high power pneumatic products for hobby, semi-professional or professional operations. Here are some of them.
From the small and handy variants, with pistol type format and small size, used for small household works, to the preferred demolition hammer versions for breaking concrete slabs, masonry and asphalt, the compressor is a “must have” for operation efficiency of pneumatic models.
These hammer versions are preferred to electric or heat engine alternatives due to their significantly lower weight, which is based on the lack of fuel tank and, respectively, the electric motor with or without battery. So they are more comfortable to hold for long periods of time and easier to use by people with reduced physical strength. At the same time, the operating system allows the use, without risks, in areas with high humidity or flammable gases.
The pneumatic hammer has a single moving part, namely the piston, set in motion by the force of the air, which strikes the surface you want to break. To choose a suitable compressor for these tools you must carefully check the volume of air with which the device works in one minute (CFM) and the pressure it creates (PSI). As a safety measure, specialists recommend opting for a model that provides an air volume of 1.25 to 1.5 times higher than that required by the pneumatic hammer.
Pneumatic screwing guns
Maybe one, two, three, ten screws you can fix with a manual screwdriver, but if you plan a slightly larger project, you will lose a lot of time without an automatic option. Pneumatic screwing guns are an efficient and affordable alternative, which helps you complete everything faster and easier by inserting a screw in place.
All models that work with compressed air include in the technical specifications the air volume and the necessary pressure. On average, we can tell you that you will need a 5 – 6CFM compressor, which generally means a tank of 30 – 36 liters, at a pressure of 70 – 90PSI or 4 – 6bar.
Pneumatic staplers and nailers
Yes, even nails can be driven with an automatic device to ensure a better pace of work, especially in areas such as the furniture industry, construction or carpentry, but also in DIY projects in your own home. Staplers are extremely useful for everything that means fixing upholstery and panels, as an alternative to small nails.
Because unlike screwing guns which require a continuous and uniform movement, stapling and inserting nails means sudden and strong blows, in this case you can also handle a compressor with a lower air volume (1 – 2CFM, the equivalent a tank of 6 – 12 liters), especially in the case of staples, with a pressure of 60 to 100PSI.
But you will also find models of nailers that need 14 – 15CFM, so always carefully follow the requirements of the device with which you will use the compressor. Don’t forget to analyze the maximum pressure limit, it is just as important to keep the pneumatic tools in the best conditions.
Compressed air spray guns
What these products offer you in addition to the traditional bidinea painting, is a shorter working time, better coverage, less dirt and a uniform layer, without stripes.
Most options for the home are provided with tanks of 500 – 800ml of paint, which helps you to quickly cover indoor or outdoor surfaces. Regarding the pneumatic variants, in this case it is good to combine them with air compressors that offers you an average circulating volume, between 6 and 12CFM, with a pressure of 36 to 50PSI or 2.5 to 3.5bar. This time you do not need high strength, because it is not necessary to throw the paint or washable lime from 10m, but constant pressure, to get a uniform appearance.
Pneumatic blasting machines
Sandblasting involves cleaning a surface or finishing it with abrasive particles (sand, metal pliers, etc.) blown with air under pressure, under water jet or by centrifugation. Most blasting machines are used for commercial or industrial purposes, either in workshops or in factories and less in private households.
As you can probably see, in order to get the best results, in this case, you need both a high pressure, high enough to remove all impurities and unevenness, as well as a continuous flow of air. For blasting machines you will therefore most often opt for a compressor that ensures a CFM of 10 to 25 and a pressure of at least 80 to 125 PSI (5.5 – 8.5bar) or more, depending on the profile of the materials used and their hardness.
Because of the compressor, an additional accessory, it is more convenient to choose a manual or electric motor version for home use, the options of silicone pistols that work with compressed air are intended especially for car workshops and industrial use. It is one of the situations in which you do not need high pressure, but on the contrary, just enough to push the silicone evenly out of the tube.
