Along with the oil air separators, there is a filter in the oil reservoir tank that needs to be changed every six months. You should contact a qualified air compressor shop for regular service.

We relocated our Sullair 3700 about 30m from air receiver, due to excess dust. Now the compressor never stops running, trips on high pressure yet the receiver is not achieving the pressure required

would say dust has done something to do with it
before you had time to move it

will need the compressor serviced

first simple words
to replace the compressor pressure shut off /turn on valve
that should fix the pressure trip build up limit problem

and maybe a partial strip down to clean out the casing
if dust build up is noted

The sullair 185 has a low oil pressure override button that you have to hold in while starting. after the oil pressure builds up(takes about ten seconds) you can release the button and the machine should continue to run.
