Picked up a McMillan MA15 Air compressor

Hi All,



I picked up this little gem for a bargain as it had a leak in the pressure switch. Turned out to be a hole in the diaphragm which was easily fixed with some bike tube rubber and a little diy :2tsup:. Much much better and quieter than the cheapo SCA direct-drive unit I have. Now there appears to be a very small hissing leak from the bottom of the filter regulator, there's some sort of coupling on the bottom of it - does anyone know what this is for?



As you can imagine there's not much info about this unit online (it was manufactured in '87), but from what I can tell it has an ABAC twin cylinder pump, Betts 2000watt motor and roughly a 60L receiver. I think the Norgen filter regulator was put on by one of the previous owners judging by the hosing. It has older style couplers (I think they're Ryco type?) so I'll need to get some of the Nitto type on there. What brands do people recommend for fittings and couplers? would rather not cheap out on something that can easily leak.



I'm also looking to spruce it up a bit, things like a quick drain release valve, maybe new gauges in Psi, new filter regulator, etc. any suggestions highly welcome.

and if anyone has any more info on this compressor please feel free. Would be good to know air displacement figures..



Thanks for reading! and we all love pics...
