Thread: P38 Air tank to inflate tires

Not really. It is a high pressure, low volume system which relies on exhausted air to cleanse the air dryer cannister. Tyre inflation is low pressure, high volume and is one way. Remember, your air reservoir is only 9 litres. However, you could replace the EAS compressor with one designed for tyre inflation and to fit in the engine bay (ARB make a great dual compressor widely used in Australia). But it is problematic whether you should just simply inflate each tyre direct from the ARB compressor or through the air tank. As the ARB compressor doesn't filter the air like the EAS one, moisture will enter the air tank if you do not add special filters and water traps.

ma il serbatoio non ha lo scarico dell'acqua come i compressori di casa?
e ancora, se passo nell'asciugatrice?
Stavo pensando di mettere in pressione il serbatoio e dal tubo che arrivava alle valvole, mettere un rubinetto con manometro

>But doesn't the tank have a water drain like home compressors?

Yes, and if you're prepared to depressurise it and undo the plug every week or so, that would be fine.


>And again, if I go through the dryer?

The desiccant cannister needs to be purged of moisture. EAS does this whenever it needs to expel air. This won't work in a one way system where there are no signals from the computer to expel air from the wheel bags back through the cannister.


>I was thinking of pressurizing the tank and from the pipe that came to the valves, put a tap with a pressure gauge.

You are forgetting that a computer controls the whole system. There will be no signals going to the computer telling it to do anything. The only issue you will have is that the compressor will overheat and the thermal switch will cut out. If you by-pass the computer and valve block and just operate the compressor directly, that will work until the compressor fails. And it will fail. It is not designed to do the job you want it to do.
