One of the top benefits of utilizing air power is that every device connected to industrial air compressors is not required to have its own engine. The electrical energy is converted into kinetic to power the pneumatic tools via a single motor only on the compressor. This means you will only need compact, and easy to handle tools that have fewer parts. These are the compelling reasons why air compressors are widely used in plenty of applications. Actually, you can find one of them sitting in gas stations as well as in huge manufacturing plants while portable units are very common in small workshops and garages used for inflatable toys and powering tools.
With the various types of industrial air compressors, piston compressor is one of the most utilized variety. Most piston air compressors units are oil lubricated which means they use oil to lubricate the working parts during the compression process. A piston compressor keeps the pressurized air away from the lubricating oil through the use of rings but these rings can sometimes be ineffective, letting some oil to pass through them and combine with the compressed air. While the mixture of this oil does not always spell a concern, it needs regular checkups and frequent oil changes to keep the quality of the compressed air.
More importantly, almost all applications can be harmed or contaminated by oil mixing compressed air. Take for example the case of spray painting application. Oil contaminating the airstream can create finish issues. Moreover, many pneumatic tools are intended to be oil-free to prevent contaminating wooden surfaces. Some address these oil problems by using an oil filter or separator in the airline but others also use different piston industrial air compressors that employ a single piece connecting rod only. It has no wrist pin and it’s the eccentric journal that moves the piston side to side or up and down. Ultimately, you can also use an oil-free air compressor that uses permanently lubricated bearings rather than an oil bath.
