Lower air (12) / upper air (13) delivery rate lever
The levers can be used to set the delivery rate of the lower air or upper air
for the mixing and delivery vessel.
Horizontal position: The air supply of the lower air / upper air is open.
Vertical position: The air supply of the lower air / upper air is closed.
The setting of the upper and lower air depends on several factors:
− Delivery hose nominal diameter,
− Type of hose coupling (integrated inside or outside),
− Delivery hose length,
− Delivery head,
− Composition of the mixture,
− Type of delivery,
− Consistency of the mix (viscosity).
