OK thanks for your replies. im glad you got those thoughts about the box.
And i think it is for a filter og an autofeed device. i live in denmark. unfotunatly i am not able to see what the brand is, because i couldnt find any place to look for it, which maked it hard to google.
and of course if you have more ideas to what it can be you are welcome to post
Nice thank you
