Determining Fan Speed
IMPORTANT:
Do not exceed 5000 rpm maximum fan speed.
NOTE:
Refer to SETTING FAN SPEED in Operating the Machine - Monitor Operation section.
Fan RPM setting will vary depending upon:
-
number of primary air runs
-
density and size of material
-
metering rate
-
ground speed
Fan speed is correctly set when:
-
equal amounts of product are delivered to each boot
-
tubes and hoses do not plug
-
hoses empty quickly and evenly when shut down
NOTE:
Ambient air temperature and altitude can both affect air flow. Adjust fan speed when these conditions affect performance.
· Single-Shoot
Determine initial fan RPM setting by adding application rates of front and rear tank products together, for combined rate. Locate combined rate/fan RPM setting in chart.
| Combined Rate |
Fan RPM |
| Light - 6-56 kg/hectare (5-50 lb/acre) |
2200-2800 rpm |
| Medium - 56-112 kg/hectare (50-100 lb/acre) |
2800-3500 rpm |
| Heavy - 112-224 kg/hectare (100-200 lb/acre) |
3500-4200 rpm |
| Extra Heavy - 224-392 kg/hectare (200-350 lb/acre) |
4200-5000 rpm |
· Double-Shoot
IMPORTANT:
Lower application rate product is usually placed in front tank.
Determine initial fan RPM setting based on the higher application rate product (rear tank).
