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
You need to replace your seperator filter, its blocked and wont let air through it which causes the safety valve to blow
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.
Depends on which safety valve you’re talking about…
The one inside the compressor or the one on the air receiver (tank)
