after a 3 months of waiting, I received my Air Sander. I am so happy and hope it will work so perfect as is looks like.
It works just fine with 50litre 2hp 198L/min 8bar compressor. if the compressor is full, after half minute motor starts to work and works whole time. I am making pause each 3-4 minutes. but It is not annoying. I am satisfied. the pad is a bit large for me. 4 inch or maximum 5 inch pad were better for beginners and also professionals who does not need to work on big flat areas like more than 2 square meters. on pictures it removes and cleans the steel door from old and bad covered colours.
