Oil Air Compressor - Oil and Oil-Less Air Compressor Pump - The Basic Variations

When one mentions of air compressors, some people who aren?t aware of them would often think of the oil air compressor. Though oil is used for lubrication, ventilation, and so on, one should realize that there are two types of air compressor pumps, the oil-lubricated system and the oil-less system. Often, various individuals would assert about which is better among the two but in fact, each have their own advantages and disadvantages depending on the application. An industrial application may require the application of one while a family usage may need another.

So as to better know oil free air compressors, it would be best to become acquainted with oil air compressors first. Oil is utilized in oil type compressors for three major functions, lubrication of mechanical parts, cooling of the engine, its parts, and the leaving air, and suspending impurities that have moved through the inlet. As for these three purposes, for oil free air compressors oil is not immediately involved in the compression mechanism. Though obviously, oil may be utilized in the motors and gearbox of an oil free air compressor.

For starters, a factor that will establish which system is finest for application is the nature of the condensed air created by the compressor. For some tools and motors, pressurized air with trace quantities of residual oil is required while for others, such as for hospital application, clean condensed air is completely necessary.

The use of the air compressor will also establish which to utilize. With the larger horsepower and SCFM rating, oil air compressors are larger in size and can create more pressurized air. Meanwhile, created for more compact uses, oil free compressors are more compact in size. This means that the best solution for bulkier functions such as construction, road work, industrial factories, and the like are oil-lubricated compressors. On the other hand, finest used for home and on the road applications, oil-free compressors are also referred to as portable electric air compressors.

The reciprocating piston, rotary screw, and the centrifugal compressor are the fundamental types of air compressors. The first two are positive-displacement type that can either be oil-lubricated or oil-less. The last type is a dynamic type and it produces condensed air with a high speed impeller which also means that it is oil-less.

Incidentally, the Campbell Hausfeld is one excellent brand that has received high ratings from numerous air compressor review sites for both oil air compressor and oil free compressor.

There are essentially two types available with an air compressor, the oiled air compressor and the oil less air compressor. Recognizing the distinctions among the two can help you know which is best for your necessities.
