8. Airlock Speed:
Refer to the following table as a guide for
setting the airlock speed. Use the flow
control to adjust the speed and count the
revolutions using the arrow on the wheel.
For optimal capacity run the airlock as slow
as possible.
Airlock speeds depend on the product and
the distance conveyed. The airlock pockets
should be as full of the conveyed product as
possible.
To determine this, start with the airlock
speed slower than the recommended
speed.
Increase the speed slightly when the
inspection window starts to be covered with
non moving product.
Airlock speed can be run too fast, not
allowing the product to fill each airlock
pocket. Never exceed the recommended
speeds!
The longer the suction distance the slower
the airlock should turn.

9. Maximum Capacity:
a. The nozzle should be placed into the
grain with the inlet below the surface of
the grain but not below the air-slide. It is
recommended that some air be allowed to
enter with the grain to obtain the best
capacity.
b. Open the air-slide about 3-4 inches to
start. Close the air-slide until the machine
starts to pulsate. Then open the air-slide
until the pulsing stops. This will give a
balanced grain and airflow condition.
