Boxes and diverters are accessories of an Air Slide System which help to change the direction of the flow and also to divide it from one Gravity Conveyor to another two. To be more precise the Aeration Box or Air Slide Box aids the material to change the direction of the system at any angle. This way we can use only one Gravity Conveyor instead of plenty more. The Air Slide Diverter has one inlet and two outlets so; we may split one system into two. In addition there is a slide gate where we have the ability to distribute the flow and productivity in different percentages, meaning let’s suppose 70 % of the feed to enter one outlet and 30 % to the other.
