Oil-free compressors: a brief guide of the buyer
Compressors are divided into two types: oil and oil-free. Of course, this is not the only classification of compressors, but certainly one of the most important. Oil compressors, as the name implies, require special work for compressor oils: it is poured into the mechanism and serves to lubricate and cool moving parts. Oil-free models do without it. In their design for the air channels and the oil separated from each other, whereas in oily compressors these channels intersect. Some lubrication in the mechanisms of oil-free compressors is present, but watch out for the oil level and refill as needed there is no need: it is not directly involved in the air pumping.
Oil-free compressors constructively simpler oil. Therefore, they are cheaper, lighter and more compact, much more convenient for them to take care and maintain them in working order. Unfortunately, this simplicity, there is a downside. For heating and oil-free compressors are often inferior oil counterparts. In addition, their service life is significantly lower, so that the oil models. Finally, even the good oil-free devices, which are used in the design of advanced materials with a low coefficient of friction, are not able to operate continuously for a long time. 10-15 minutes after the unit starts to overheat, which can lead to premature failure.
Based on the structural features, we can conclude the appointment of oil-free compressors. They are best suited for home use. For example, to apply oil-free compressors for automobiles, which many carry with them in the trunk - just in case. Besides oil-free aggregates give much more pure compressed air compared with oil without impurities that same compressor oil, so they are recommended for power pneumatic tools. Anyway, most of the oil-free models refers to the domestic class, so for professional or industrial use are not suitable (although there are exceptions to any rule).
The simple design and high popularity among buyers of oil-free compressors have led to the fact that these devices produce a variety of companies around the world.
