Now that you know the importance and several benefits of an air compressor, you sure want to buy and utilize one. However, the confusion that has plagued buyers over time is the debate between which air compressors to buy: the oiled ones or the oil-free ones. The aim here is to help you decide which suits you best and we shall analyze the advantages and disadvantages of both these types.
Oiled vs Oil-Free Air Compressor
Before delving into the pros and cons, it is important to understand how an air compressor works. The air compressor first draws air from outside through a piston and then this air is stored in a tank, after being compressed. However, the piston chamber needs adequate lubrication in order to function properly and efficiently. It is due to this lubrication that oil is used in the oiled air compressor. In the oil-free ones, which are pre-lubricated, Teflon is generally used.
Both the oiled air compressors and the oil-free air compressors have advantages and disadvantages.
The oil-free air compressors are much less expensive compared to the oiled air compressors.
Size and Portability:
The oil-free air compressors are also much light-weight than the oiled air compressors. Oil-free air compressors are portable in nature and as such are used for work around the household. Oiled air compressors are more bulky and heavier, and are generally meant for commercial use, or for those who need it regularly and for high-end jobs in the household.
The oil-free air compressors are pre-lubricated, generally with Teflon, and thusrepeated lubrication with oil is not necessary as it is in the oiled air compressors.
In terms of durability the oiled air compressor lasts much longer than the oil-free air compressors. The oiled air compressors also produce much less noise than the oil-free air compressors.
Type of Job:
The oiled air compressors can be and generally meant to be used commercially, in jobs like petroleum coking. The oil-free air compressors are not meant for commercial use, but can be used for common DIY jobs like filling tires or supplying air to a jackhammer.
The oiled air compressors are much more powerful than the oil-free ones. Therefore, the former is used commercially.
Which one should you buy?
As the analysis has already revealed, investing in an oiled air compressor will be more feasible and satisfying in the long run due to its durability and also capacity for commercial use. Moreover, it will be never frustrating as the lubrication can be controlled by you, unlike in an oil-free model. Although heavier and more expensive, it is advisable to spend some extra money on this model. It is always better to buy one good thing rather than two separate compressors, after one fails to perform. Not only does this saves money, but also prevents frustration on the part of the owner. However, if you are willing to use it occasionally and for very basic work around your household, then you can indulge in an oil-free model.
