    You get special oil for compressors. Please dont use veg oil, those compressors are high pressure, accidents could happen. I just cant remember what oil, i seen it somewhere. If i remember i will post here.

    If the oil is exposed to the high pressure air then it should not be hydrocarbon based as it will catch fire.....same cause as dieselling in an airgun....
    This eliminates anything originating from crude oil and vegetable oils.

    So it would probably need to be a special purpose oil, perhaps silicone based .... did you not get literature / instructions with the unit or can you not download a set?

    The manual for that compressor says:

    10: The machine oil should be checked
    regularly, make sure the oil level is above
    the upper edge of the red point. If color of
    machine oil becomes dark and black, it
    should be changed in time.
    (46# anti-wear hydraulic oil of the national
    standard is recommended)

    Hi all!
    I recently bought one of these from Henk. Do you guys that also own one also find the air they put out has a mild oil smell? I topped up my 6l 300bar dive bottle the other day from 220 to 300bar just to see if it can - very impressed, did it in 8 minutes. When I filled one of my guns this morning from the tank, the air from the bleed valve does smell a bit like the oil. Similar to but less pungent than the smell that comes from the breathing hole while the compressor is running.

    The in line filter is clean and dry without significant oil staining.

    I'm well aware that this isn't a breathing air compressor, but just want to check whether this is normal or at least a similar experience to that of others?

    Cheers

    If any oil is getting through it should smell of burnt oil. At 300bar the oxygen partial pressure is 63bar - more than enough to spontaneously oxidise/combust any hydrocarbon that passes through.

    Thanks JXV!

    I certainly haven't heard anything unusual during operation that made me suspect dieseling...
    Also some of the posts on TAG showed relatively vast amounts of compressor oil coming through into the filters when running machines with oil getting through. They were using bauer and coltri compressor oil i think - not sure about whether those also diesel?
    The one that got sent with my compressor is something called MatAir PP (peak performance) Compressor Oil. Looks like a relative no name brand from tradecounter.co.za. Actually no info on what exactly it contains that I can find.
    As I say, there is basically no other evidence of anything coming through at all apart from this slight smell.

    It was the initial preinstalled filter I was running with. I suppose I ought to have checked it properly before I ran the thing too. It had a few very small streaks of black/brown staining on the outer surface when I had a quick look before running it. Nothing that came off on my fingers or seemed greasy. Thinking about it now it could well have been some sort of basic oil that burned off in there during the fill, causing the smell.

    I have replaced the filter with a completely clean one. I suppose there is nothing to do but see what happens next time... Although may be difficult to objectively tell without completely emptying the whole cylinder and refilling it, which I doubt this little compressor could handle without catching alight :P
