The wind start by the blower, enter the curtain valve, and the reservoir.
Of the reservoir where it is stored in the good pressure, It is forwarded thanks to windtrunk, in the pallet box.
When a pallet is lowered, the air is introduced into the key channel and, if a stop is pulled, it enters finally the pipe.


A good road of wind has to have the shape of a funnel, always smaller and smaller :

Reservoir - windtrunck - pallet box - key channel- pipe foot

If the funnel shape is not respected, there could be air flow problems.
