Updated design
Hi everybody, I haven't finifhed yet, but since we only have one day left, I wanted to share with some ideas to help you go ahead faster, 1) I reduced the dimensions of the system 25*23*9 cm instead of 40*30*20 2) Gears are between two walls and are isolated from the rest of the system 3) I added two PEEP valves, one for the low pressure and one for the high pressure which will work as a safety valve 4) A small PVC standard valve is used to adjust low pressure 5) I integrated the filters in the main body, it avoids adding a lower part, I used the CHUWI Robot vacuum V3 80*40*15mm filter, I chosed to use two stages of filtration (it could be less or more depending on filter efficiency), the filters are maintained by metal grid. 6) Low pressure zone and the vaccum zone are completely separated. There is just a safety valve if the passage is blocked. Waiting for your feedbacks/comments.
