Here’s the thing. If you have low outlet pressure in your air compressor, and you have tank pressure, there’s likely a compressed air transmission problem!
Let’s look at what’s in the air pathway between the compressor tank to the discharge (outlet) coupler into which you plug your air line.
You have the compressor air tank. Is it full of air? One of the two air gauges on your compressor displays the tank pressure. Is the tank air pressure displaying a tank pressure? Is that tank pressure the typical cut out pressure setting of your air compressor?
If your air tank gauge is not displaying a pressure, or very low pressure, then that would be the logical reason why your air compressor has low outlet pressure.

The other air gauge on your compressor displays the setting on your air regulator.
The air regulator controls the flow – and thereby – the pressure of compressed air flowing downstream to your air compressor.
