The robin air is what we use for filling thats all,

It gets a bit long winded trying to fill coach systems with a bottle and scales lol, so just program the machine and walk away and let it do its thing.


Ive only been doing A/C for about 4-5 years now so i dont know everything about it tbh!
May sound silly also but i have no idea how car compressors work! Most of my training and daily work is on sutrak & thermoking systems,

But essentialy a/c is a/c it still works in the same process cycle,
