Is it better to have oil or no oil in the air compressor

The difference between an oil air compressor and an oil-free air compressor is that the working method is different and the final discharge gas is different.

1. way of working

1. Oil air compressor: There is lubricating oil in the head of the oil air compressor itself,

2. Oil-free air compressor: Oil-free air compressor does not contain lubricating oil in this working process and is lubricated with water.

2. the final exhaust gas is different

1, oil air compressor: oil air compressor with oil lubrication, so the final discharge of the gas containing oil.

2, oil-free air compressor: oil-free air compressor with water lubrication, so the final discharge of the gas does not contain oil.

Oil-free air compressor is cleaner and more environmentally friendly than oil-free air compressor to some extent, so institutions such as hospitals, laboratories, schools and other institutions are very suitable for the use of oil-free air compressor, and these institutions also prefer to use oil-free air compressor.
