Air compressors are mainly lubricated or non-lubricated types.This is defined by the lubrication of the Air Cylinder fitted with Air Compressor.In many industries clean,oil free compressed air is the main requirment for product production.In old days lubricated Air Compressor vastly used due to efficiency reasons,but in pharmasuitical industries oil free compressed air is the standard requirment.This can be achieved by non-lubricated Air Cylinder.

As there is no lubrication to Air Cylinder,some particular care must be taken for Air Compressor fitted with non-lubricated cylinders than lubricated cylinders.Corrosion formation on non-stainless steel elements requires thorough investigation.As compressor works,some condensation are formed.The lack of an oil film on the non-lubricated Air Cylinder walls are subjected to severe corrosion caused by condensation.

You may face some problems due to corrosion in cylinder walls while using the compressor.The first drawback is wear-out ratio of piston rings are high.
Therefore the cylinder walls must be protected against corrosion and the cause of condensation must be eleminated.We should not neglect condensation.

You may not observe problem in running condition,but when Air Compressor is idle for long time,corrosion will creat severe problem.To avoid this some
care must be taken before stopping the compressor.

Precautions to be taken before stopping the Air Compressor.(Fitted with non-lubricated cylinder)

01)It is recommonded that water safety device must be fitted but due to any reason,when there is no water safety device fitted,stop the water supply a few
minutes before stopping the Air Compressor and allow the compressor to run unloaded.This allows the condensation to drain.

02)Do not keep Air Compressor idle for long time,it should be run for atleast half an hour every week.

03)Unloading piston in suction valve cover be cleaned atleast once in a month.Apply slight grease or silicon to avoid sticking.

04)The Air Cleaner Element must be kept clean at all times,clean it every 500 working hours from inside out.

You are suggested to add in this list,if you know something about this.
