This question is only for people who use OIL FREE compressors.

So, here lies a problem I just can’t get rid of fish eyes and it’s only from one of the compressors I use. Just to let you know, I’m a long term experienced body repairer so I’ve seen plenty of paint related problems but this one just won’t go. At my small workshop at home I use a TEH (silent??) oil free compressor 50ltr which is around two years old. It’s not overworked. What ever I do I just get silicone in my paint. It’s been like this now for around 6 months. The area is an oil free environment, the airlines and guns get used at other premises and produce good clean results. The paints I use follow suit. My last compressor was typical oil lubricated but died after many years.
So, I googled oil free compressor and it states it’s Teflon coated and has possibly silicone based seals to operate. Has anyone else noticed similar as if so I might have to yet again replace it?

Of course you are using a good oil/water separator and a filter yes? They are still needed on so called oil free compressors. Could it be something environmental? Perhaps a varnish or something treated which is giving off fumes?

How good is your air filtration, what are you using?

Plus this helps

Middle of the road Clarke. I also know about silicone drops as those aren’t new. It’s the cause I need to establish but thanks
