Adjusting Double-Shoot Damper

Damper is adjusted by turning crank handle (B) and observing color-coded position indicator rod (C). Color coding shows that internal damper is:

NOTE: On tow-behind cart, damper crank is located on the underside of the plenum to avoid interference.

Color Code Damper Position
Blue Full Down
Green Between Down and Center
Yellow Centered
Orange Between Up and Center
Red Full Up

 

When the damper is adjusted up, more air is delivered to the lower tubes; when adjusted down, more air is delivered to upper tubes.

When single-shooting with a double-shoot plenum (only top or bottom tubes active), adjust damper to completely block air flow to inactive tubes.

In true double-shoot (both top and bottom tubes carrying product), set fan speed for higher rate product; then adjust damper to reduce air flow to lower rate product tubes.
