There. I finally purchased a compressor to power my airbrush. I visited a couple of stores and decided to invest my pennies in a sparmax.
Now before I start airbrushing, I would appreciate some pointers.
How do I adjust the pressure? The compressor didn't come with much of a manual or instructions, only a one-page read-before-using sheet. That sheet said that the pressure is adjusted by turning the nut at bottom of the moisture trap. However, the thingy in the moisture trap is different from the first pic and the exploded view in the instructions (this drawing shows the moisture trap with a nut with threads on it).
Below is photo of the real thing:

And, how much pressure do you usually need when airbrushing? The gauge in the compressor has PSI's while most tutorials etc. in finnish use BARs...

All pointers will be appreciated.
