Hi, I have two compressors working together when spraying, only one when I am just using an air tool
Is it possible to fit nun return valves to prevent one compressor filling up the other
Yes, in fact both compressors will already have non return valves, to stop the tank loading the pump when it gets up to pressure and switches off. However you would need another, in the line between the two compressors for your job. Also you would always need to use the same compressor, as the other would still fill both tanks.
Thank you for your replys, I use a single compressor alternatively so as to spread the wear
So two check valves seems to be the way to go
Thank you for your help gentleman
