Best Oil Lubricated Air Compressors

Air compressors are designed with many different features, each having their own pros and cons. There are large capacity compressors available for use with industrial jobs, as well as smaller compressors that are portable and can be kept in a home garage or used in a work vehicle. One of the main differences in air compressors, no matter the size, is whether they are oil lubricated or not. 

Those without oil lubrication in the pump mean less maintenance and no need to monitor oil levels or refill oil frequently. The downside of compressors that don't require oil is that the pumps often don't last nearly as long. For those who are looking for a compressor that will be a long term investment, especially for heavy duty work, it may be best to put in the extra money up front for a unit that is oil lubricated. 

When shopping for oil lubricated air compressors, you should look for one that has a sight glass where you can monitor the oil level while in use. It's also helpful to find a unit that is easy to refill when needed. The following are 7 of the best oil lubricated air compressors available for purchase.
