Level 2 and level 3 use fire resistant water glycol hydraulic fluid to lubricate and cool. It is safety and explosion –proof.https://www.alibaba.com/product-detail/300bar-High...Do you think that this one can be used for liquit air production?

    Would it be possible to use an oil-lubricated compressor with an oil-filter?

    Does it need to be an Oil-Free compressor or is it possible to use an Oil Lubricated compressor?

    Arduino Ublox GPS

    As soon as I go insite gps.satellites.value() becomes 0. It keeps giving information dough, which can not be recent information. Well, I'm planning to use it outside anyway.

    It works now! I did wiggle the antenna connection but I don't know if that was the problem. I notice that when I start the program outside it works even when I take it inside while it is already working, it keeps working. When I start de program inside it doen't work even when I take it outside. So I have to start it outside.Thanks a lot for your help!

    Arduino Ublox GPS

    Serial monitor shows:

    Thanks! I have tried that and given the fact that I can see its version, I assume that the connection between the Arduino and de GPS sensor works.Today when I tried it in the train home it was giving the time again like yesterday.

    When I swap wires Serial Monitor gives this:

    My GPS sensor doesn't work. Yesterday I got the time, which was correct, but no location. Most of the time it just gives INVALID and 0. Serial.println(TinyGPSPlus::libraryVersion()); gives 0.92 so I guess the SoftwareSerial does work.Any idea what could be wrong? Thanks!
