1987 Ingersoll Rand 185 blowing air out of pressure relief valve.
The air compressor is starting fine but when i push the air button the pressure relief valve blows out air and oil

Seperator
You need to replace your seperator filter, its blocked and wont let air through it which causes the safety valve to blow

Another solution
Had same issue diaphragm in unloader was torn cost about 60$ now works perfect.
Of course had to adjust regulator as well.
Could see where if regulator not working properly could cause same issue.

IR 185 continuously builds air…
what if it’s not the diaphragm in the regulator? And has new separator filter and still keeps building air.

Safety Valve
Depends on which safety valve you’re talking about…
The one inside the compressor or the one on the air receiver (tank)

I am having the same issue as being described here. I replaced the separator and still have the issue. I disassembled the unloader but do not see any type diaphram.
Is this the unloader valve you guys are referring to?
