There are some points that they aren't clear for me.
On the 05-06-14 I sent you the attached email with conveyor belt from silos to press scheme. It is different than that you sent me.
In any case, I want know if for you is everything clear about the suction point that you need for aspiration filter of your supply.
Please let me know if you need more detail about suction point and quantity of air that you need to suction.
