We have oil in the air from I/R P380 rotary screw air compressor I have an ingersoll rand P380 compressor, it is putting oil into the air? Do you know how we can fix this problem?

Thanks, William

Rotary screw air compressors contain a lot of oil used as a sealant as the air is forced into ever smaller compartments as the screws turn.

As the air is expelled from the screws into the tank or the mains, it passes through an oil separator. It seems to me that if you are now getting oil into the compressed air, and it’s in greater quantity than before, your oil separator needs work.

For this, you need the manual from I/R.

In the interim, you can install coalescent filters at point of use to remove oil from the air-stream if that’s practical.

i have a ingersoll rand p130 wdg compressor. I have just put h32 oil in the separator.

The problem is that there is quite a lot of oil coming out of the air pipe?

Thanks, Trevor


Hi Trevor.

I must confess that I don’t know why you would put oil into an oil separator. It’s function is to strip oil used in the air compressor from the air stream as it exits the compressor.

Adding oil seems to me to be counterproductive.

Anyone else have any ideas for Trevor?
