Oil mixed with paint when spraypainting

by DeeCee
(South Africa)

Hi, My name is DeeCee and I reside in Port Shepstone, Kwazulu Natal in South Africa.

I work for a panelbeating company and noticed that for the past few months there are a lot of complaints with the paint work (Fish eyes etc.)

Just recently we found that oil was present through the airline. What causes this and what can we do to resolve this problem?

Your help will be greatly appreciated.

Thanking you kindly,

DeeCee, you don't indicate what type of air compressor. Regardless, if it is oil lubed, then compressor lubricating oil is getting past the seals that are supposed to prevent that, and getting into the compressed air stream.

Not only will compressor oil create fish eyes, it also has a reputation for destroying buna N seals in air tools and the like.

Visit the site map and look for the COALESCENT FILTER link. Have a read about these. In my opinion you need to add one just upstream from the spray gun, to take the oil out of the compressed air stream.

Cheers,

Bill

Hi DeeCee

If it is a screw type compressor, the oil seperator folter is bust. You also have to have an in line filter as Bill says.

 Safety of using a compressor

How safe is the compressor for spray pianting.? Does the OHSAct say anything about this at all?

If the question is about spray painting, then, depending on what you are spraying, and how far the compressor is from the air gun, you can spray paint darn near any product with the right air compressor.

As to OSHA, I suspect they have some requirements for proper masks for breathing while painting with some nasty coatings. I'll leave this to an OSHA expert to reply on, or you might visit the OSHA website for details.

Air brush painting uses compressors, auto painters uses compressors, the concern isn't with the compressor so much as what it is you are using to paint with.

 Air dryer

I also recommend an air dryer. When the water is removed from the air it tends to take a lot of the oil as well. You also don't want water in your paint work either.
