A compressor is a must-have component for most air tool models. Such equipment is used both in private households and in specialized workshops. There is also a separate category of industrial equipment, the representatives of which also require the connection of compressors. A variety of pneumatic units makes it difficult to select additional components, however, provided that the equipment is properly equipped, the user can count on a high-quality result in the process. The question of how to choose a compressor for a pneumatic tool, of course, in the first place involves the mention of functionality, reliability and durability. But even compliance with these characteristics does not always provide the expected effect of using the tool.
Basic selection options
An experienced master evaluates compressors according to three main characteristics, including pressure level, productivity and receiver volume. As for the first criterion, the initial indicator is 6 bar. This is the minimum pressure value that the compressor has for pneumatic tools, designed to perform simple domestic operations. Widespread and models with a pressure level of 10-15 bar. This equipment is able to work with more demanding units, including those from the industrial sector.
The performance of compressors is expressed in liters of working mixture sprayed over a minute. So, to perform small-scale paint events, 10-50 l / min is enough. But this range can be expanded to 500 l / min, when it comes to the use of equipment in the workshop. The volume with which the compressor works for household pneumatic tools, on average, is 7-10 liters. Of course, there are more spacious receivers, but for the most part they are used in highly specialized areas.
What type of compressor do you prefer?
Segmenting compressors by type depending on design also helps make the right choice for inexperienced users. Models that are positioned as automobiles are suitable for most household needs - from painting surfaces to blowing rubber mattresses. A win-win solution can be a piston unit, which is used by workers in workshops and ordinary car owners. If the question is which compressor is needed for professional pneumatic tools, then you should pay attention to screw and belt models. Such devices typically have high power rates and pressure levels.
Dimensions and design features
In addition to technical and operational indicators, it is important to take into account such characteristics as mobility and size. For example, if you intend to work with a spray gun for painting the fence, then you should turn to lightweight and ergonomic devices. Even if they provide a minimum level of performance, it is more likely to be enough for simple operations. Such models, in particular, include a coaxial compressor for pneumatic tools. The choice in this direction can focus on oil-free equipment, which does not have a receiver at all, but wins in compactness. If you need a powerful and efficient compressor with a massive body, it is recommended to purchase models equipped with convenient handles and wheels.
Additional equipment - what to consider?
Buying only a compressor does not mean that the connection to the instrument will be correctly configured, and the work will be done qualitatively. The technical organization of the process often involves the use of special hoses, adapters and clamps. As practice shows, even a lightweight pneumatic tool when connected to a compressor requires the use of clamps with suitable sizes. Do not ignore personal protective equipment. If the compressor for the pneumatic tool will provide spraying of abrasive materials, then it is necessary to take care of protective headphones, gloves and glasses. To work with paints and varnishes, it is also recommended to purchase overalls that will provide protection against chemically hazardous substances.
Compressor manufacturers
Almost every manufacturer of construction or industrial equipment contains compressors for various purposes in the line. If we talk about domestic companies working in this direction, then Caliber and Elitech come to the fore. The products of these brands may not always be able to compete with the best foreign models, but for the price this is the most profitable acquisition. However, the question of how to choose a compressor for pneumatic tools with a high level of quality should be solved with the help of foreign products. The assortment in this segment is wide enough, however, the most trusted specialists are Fubag, Metabo, Senco and others.
Conclusion
According to user reviews, during the operation of compressors, subtle nuances in the characteristics of equipment that were not taken into account during the purchase often come up. These include, for example, noise level and power consumption. If you choose a compressor for pneumatic tools with plans for regular use, then it will not be amiss to take into account these criteria. In addition, the long-term use of such equipment is only possible with proper maintenance. Even if you purchase a model from a well-known company of the Fubag level, you should not have high hopes for the compressor working life. Still, the function of a pneumatic tool has a serious impact on the technical resource of the equipment used, so you can’t do without regular oil changes and observing operating rules.
