Problem solved. Now works as it should

A few days ago I asked the question"Installed today and there is a big leak in the regulator. What can be done to fix this problem?" Found found out that the problem wasn't with the filter but with how I connected it. He came without instructions, which made matters worse. I connected the supply hose to the end next to the regulator, which was wrong and resulted in a massive air leak at the regulator. I'm writing this in case someone makes the same mistake I did. The supply hose from the…

Works well, minor quality control issues.

I had serious problems with moisture in the air intake. I installed this setup and it pretty much fixed my problems.

This allows the water trap to be positioned correctly, which is why I bought it. As for the regulator, it is…

All round great little system

I was really impressed with this unit. The kit included all the accessories I needed, tape (although it's very flimsy), and everything came mostly assembled. The way they designed it makes each module interchangeable. I actually removed the gauge module to check the pressure, everything worked great without the filters attached. The supplied instructions are very short and poorly translated. Luckily everything is marked with flow arrows on top of each module and there are blocking and pressure…
