Oil Lubricated Vs Oil Free Compressor

Therefore, it’s a great choice for industrial compressors. They are the most common type with the traditional lubricating system.

They require oiling and changing the oil on a regular basis.


Oil lubricated vs oil free compressor. Pressure lubrication is the system of choice for heavy duty applications. After effects an air compressor gets its power from sources like an electric motor, diesel, or gasoline engine. Therefore, it is inexpensive than an oil air compressor.

Routine maintenance and regular oiling tended to make oiled compressors more durable and have a longer lifespan than the first. This is due to the high compression ratio will be achieved in a single stage of this compressor. An air compressor using oil needs to have it changed constantly.

However, there seems to be unnecessary confusion because some people compare all different types of compressors at once when in fact the debate, at its core. The answer is quite simple. Oil air compressors are likely to be more durable and more functional.

Generally, oil lubricated air compressors are more durable than units with oil free design. Some oil free compressors use injected water to remove the heat created by the compression process. How many oil changes will depend on its design and the total period it has been utilized.

An oil free compressor has less parts than an oil lubricated compressor so therefore is lighter in weight, as well as cheaper in cost. Oil free compressors can only support small amounts of usage and have a shorter life span, so would be ideal for more domestic applications. Oil lubricated compressors last longer.

The traditional oil compressors apply two methods of lubrication. The oil lubricated have the same construction of hvac reciprocating compressor but the oil free have less good construction, the piston and the connecting rod are made one piece so the piston and connecting rod like t and the piston move with 2 angles with the same action of crankshaft and the o ring work hard to compensate this effect.
