Sandblasting is a modern process that allows you to effectively and gently remove dirt and corrosion from materials and various types of surfaces. Modern sandblasting is no longer based on the use of sand, but other abrasives and compressed air as the working medium. Therefore, it is necessary to use a sandblasting compressor to make the process effective and efficient. We advise you which sandblasting compressor to choose and what to pay attention to when making a purchase.
Is a compressor necessary in the sandblasting process?
Sandblasting involves blast cleaning using sand. It is from this basic working factor that its name comes from. Modern sandblasting is done using different materials and methods, although the name has remained the same. Many industries use the sandblasting process due to its wide application and numerous benefits. Steel elements are blast cleaned using a sandblaster, where a specialized metal sandblaster works best. It can also be used for glass engraving, soda blasting of machines and many other activities.
Modern sandblasting, also called soda blasting or shot blasting, is performed by using an abrasive powered by compressed air. Using such a connection in contact with a dirty element effectively removes all types of dirt, paint remnants and corrosion. Sandblasting the surface is used wherever other cleaning methods, especially chemical ones, have not been effective. Since modern sandblasting methods are based primarily on the use of compressed air as a working medium, it is necessary to equip the plant with a compressor sandblaster. This will allow you to do your job better and more efficiently.
What sandblasting compressors do manufacturers offer?
Basics Sandblasting equipment must be efficient and effective. The most important element of such a sandblasting set is the compressor. Regardless of whether it is a small sandblaster or a larger machine. It is worth investing in high-performance devices, even those with larger dimensions, because they will ensure adequate comfort of work. Their smaller and less efficient counterparts, such as the mini sandblaster, do not meet users' expectations in terms of the demand for compressed air necessary for sandblasting. It is also worth paying attention to the capacity of the sandblasting compressor tank that we will use for work. The absolute minimum is a tank with a capacity of 200 liters of compressed air and a compressor for a sandblaster with a capacity of 4000-5000 l/min and an operating pressure of 6-8 bar.
There are no technological contraindications to the effect that compressors with lower efficiency or tank capacity cannot be used for sandblasting. Although sandblasting with a 50l compressor is possible, working with such a device will be less effective, less efficient, and its results may differ from expectations. Specialists also note that a sandblasting compressor with a capacity below 2000 l/min may not meet the challenge of sandblasting powder-coated surfaces. Paint applied using this method is extremely difficult to remove, which makes it a challenge for the sandblasting unit.
Sand blasting machines are primarily screw compressors, although this is not the only possible solution. Siphon sandblasters are recommended for home use due to their easy operation and low operating costs. Manufacturers offer compressors for sandblasters in both combustion and electric versions. Much depends on the place and conditions in which the sandblaster will be used and on possible access to electricity. If you don't have access to electricity, a combustion compressor for sandblasting will be perfect.
What should you pay attention to when choosing a sandblasting compressor?
When making a purchase, we face the question: which sandblasting compressor will work best? First of all, the sandblasting compressor should be selected according to our needs and the type of work performed. A completely different sandblaster for a compressor will be recommended for home use or for occasional use than a compressor for sandblasting for industry and continuous use. It is also worth considering devices that will work with a sandblasting compressor. It is best if the parameters of individual machines allow for their effective cooperation. It is also important to select appropriate nozzles that enable the full potential of the sandblaster to be used for sandblasting.
Compressed air is a medium commonly used in industry. It is also used in cleaning processes, where it is irreplaceable in removing the most difficult to eliminate substances - e.g. paint coatings or corrosion. Thanks to our short guide, you will find out which sandblasting compressor will be best for your plant and whether it is worth buying a sandblasting compressor for semi-professional use.
What is sandblasting?
Sandblasting is a popular method of cleaning surfaces. It involves blast cleaning using sand or other loose materials. What to sand with? In addition to traditional sand, the blast cleaning process also uses crushed glass, shot or soda. It is used in many industries, usually for cleaning elements made of steel, soda blasting of machines, engraving on glass, as well as in construction, e.g. for cleaning building walls. Blast cleaning is irreplaceable when removing corrosion elements, old paint coatings or difficult-to-remove dirt, and it works wherever regular chemical cleaning products cannot cope.
Pressure blasting
An essential element in the sandblasting process is the use of pressurized air. Therefore, an essential element is the use of an energy source in the form of an air compressor. The basic question for people who decide to use sandblasting in their plant is which sandblasting compressor to choose. Not every compressor will work in this role.
The sandblasting process requires the use of a high-performance compressor. In industrial applications, air compressors with a capacity of 4000 to 5000 l/min are recommended. Such devices ensure adequate effectiveness and the appropriate pace of work. Moreover, the sandblasting compressor should be equipped with a pressure tank with a capacity of at least 200 liters, which will ensure adequate continuity of work. What pressure is appropriate for sandblasting? The pressure generated by the device is also important in the process - for industrial applications, it is recommended to use air compressors with a pressure of 6 to 8 bar.
If you intend to sandblast at home, you will certainly not be looking for such efficient equipment. However, you must take into account that this process will take much longer and will not be as effective.
How to choose the right sandblasting compressor?
In the case of sandblasting, screw compressors are the best solution. However, a wide selection of devices on the market does not make the choice easier. So what should you consider when choosing a sandblasting compressor? In our article, we will focus on devices intended for professional use and indicate which compressor to choose for sandblasting. When choosing a compressor for blast cleaning, its technical parameters should play a key role - efficiency, working pressure and engine power.
What capacity of a sandblasting compressor will be the best? For industrial applications, electric screw compressors with a power of approximately 22 kW will be best. Only such devices will ensure adequate device performance of 4000-5000l/min. When blast cleaning, the pressure generated by the compressor is also important - it should oscillate between 6 and 8 bar. Please remember that if the compressor's capacity is less than 2000 l/min, the most difficult contaminants - e.g. powder coating on rims - will not be effectively removed. At the same time, compressors with lower efficiency, e.g. 500l/min, will also work well for semi-professional applications. However, please remember that the cleaning process will be longer and less effective.
The capacity of the sandblasting compressor should also be adjusted to the requirements. Too many reception points connected to the device may affect the system's performance. It is also worth remembering to use appropriate filtration. At the same time, if the demand for compressed air varies over time, you should consider purchasing a device with a frequency converter, e.g. ALUP ALLEGRO with a wide range of efficiency and power.
