196x 1 Hydrovane Compressor - Number_Cruncher
I've recently bought an old Hydrovane compressor for a song, and I'm beginning to do it up - the problem is that I've never worked on a Hydrovane before.

It's quite an old one, I think it's a 9pu - the one on the left in the picture at the top of this page;

I don't have a manual, and there's a knob / valve / tap at the lower end of the compressor, and I don't know what it does. Does anybody know what it does, and how it should be adjusted?


Stand by for questions on Brook single phase induction motors!

Could it be to let water out if it has been compressing damp air?
