I, sadly, have had to de snot several pneumatic systems and it 'snot fun. I use Relton Air-Flo air tool oil in my tools. The bottle says it contains PTFE. I don't know where this bottle came from, probably bought from one of the tool houses.
I run a light spindle oil in my FRL's on the presses. They all are equipped with Ross control valves which specifically state to not use air tool oil. They even state do not use marvel or those types. They contain something that will destroy the Buna seals in the valves.
I have used. I use Marvel Mystery. Air Tool Oil tale: Many years ago when I was selling tools to mechanics, there was one that was using diesel fuel as an air tool oil. He kept sending in his 1" Air Impact wrench for repair because the anvil kept breaking. No one could figure out why until he told what he was using as lubricant.
Seems the diesel fuel was detonating as if it were in a diesel engine due the the air pressures used with a resulting extra power kick that would break the anvil. He stopped using diesel fuel and the problem was solved. I have been mixing 1 part Marvel to 2parts light hydraulic oil, makes my Cleco die grinders run good.
I have good ventilation, straight marvel can be pretty strong smelling. I think Forrest might emember this: Marvel Mystery oil was originally intended for "top cylinder lubrication" in internal combution engines.
The Marvel Mystery Oiler fit on the intake manifold and there was a valve that allowed the oil to enter the partial vacuum in a metered amount. The purpose was to lubricate the intake valve guide the exhause valve guide might have got some by the carry over during valve overlap. Of course the piston rings and cylinder wall got their share. The stuff has to have a strong solvent to cut the lubricaing oil and carbon deposits that caused sticky valves. It also had to be able to stand high temperatures and still lubricate.
Tremendous advances in crankcase oil chemistry and positive crankcase ventilation have made this set up un necesary. But Marvel lives on. The upshot of the matter is that any oil that can put up with going through a hot engine is certainly not what one might want to breathe.
In addition, the exit air stream of an air tool using Mystery Oil is falmmable. There would be more horror stories if the exit air stream wasn't so cold. Rotary air tools are straight expansion engines, however the reciprocating tools, anything from chipping hammers to rock drills, can have compression during part of their strke. Light, flammable oils can "Diesel" when the air that carries them is suddenly compressed.
I think I'll stick to air tool oil. Marvel also makes an air tool oil. I usually use Dextron myself. Question is which oil would be best for the lubricator. It is a Speedaire lubricator for the air line. I searched the manufacturer site and it says to use any light weight oil for air tools. No specific type. Which would be best? Use oil for the usual couple drops in the hand air tool with each use? Marvel mystery oil? H-M Lifetime Diamond Member. Joined Jan 31, Messages 6, Air line oil. Joined Feb 7, Messages 5, Yep air tool oil.
I use marvel mystery air tool oil. Joined Jun 7, Messages 7, Light turbine oil would also be a good choice, maybe that is what air line oil is? Waller Brass Former Member. Joined Mar 10, Messages An excellent choice would be quantonious oil as used on many highend CNC machines, can't be beat and smells of elderberries.
