Carry the spray droplets safety to the target and increase plant deposit
Minimize off-target deposit due to wind drift or loss on the ground
Open the crop and obtain good penetration even with a low volume rate
Ensure a high coverage

With TWIN air assistance, energy is added to the spray droplets to improve control with the spray liquid.
Using TWIN it is possible :
The fan speed is infinitely variable and can produce from 0 to 35 m/s (78mph) air speed at the air outlet.
This equals from 0 to 2000 m
3
air/m boom/hour (3,872 CFM/A boom/hour).
The air speed must be adjusted to the spray job. The tables below give a guide line.

The main purpose of the TWIN angling system is to counteract for the negative influence which wind direc-
tion and driving speed have on the quality of the spray job. Further the ‘’co-angling’’ at air and liquid can help
‘’opening’’ dense crops for better penetration.
The TWIN FORCE air system can be set at any angle from 40° forward to 30° back (defined by air stream)
