Oil in air filter – setting Sullicon control to inlet valve.

Oil haze is coming back up through air filter during shutdown?

Also how do you set the linkage correctly for the sullicon controller to the air inlet valve?

These are likely related. The butterfly intake valve is supposed to completely close running unloaded, and gradually opens as demand increases.

The haze probably means the valve isn’t fully closing, which could be either maladjustment of the linkage or the sullicon diaphragm is failing.


Inlet Valve
by: Carl

The reason that there is oil mist coming from the air filter is that the inlet valve isn’t sealing properly.

To stop this you need to fit a service kit to it, BUT if you try to do this yourself then you need to be very very careful, the inlet valve has a very strong spring inside it so if you don’t know how to dismantle it properly it can be fatal, so please please get a qualified compressor service engineer to do it.

I don’t know what you mean when you say “setting the linkages” on your compressor? Please could you give a little more information
