[Hydrawerk]

Now this compressor is assembled again and it works fine. It's a cheap chinese product bought in Bauhaus shop in 2012.

Sorry for answering late.

> what is the power (current) of the engine. This is not visible on any of the pictures

According to the manual it consumes 12 Amps at 12 Volts. I did not measure it, but I believe this figure. Please see this: https://plus.google.com/photos/106264218831814439783/albums/5814895676942736977/5814896464339355346?pid=5814896464339355346&oid=106264218831814439783

> also from the picture not clear if the valves can be manipulated so that it becomes a vacuum pump

I did not dismantle the valves, but I do not think it is possible.

-> how much did you spend/where did you buy it?

It cost less than 1000 CZK at Bauhaus hobbymarket.
