6.3.6 - Pressure Monitoring
When the fan is in operation, a high volume of air flows under the metering units, to the distribution
heads then on to the D-cups. At the same time, air is directed through the metering units (front and
rear only) and out inside the tank. This creates equal air pressure above and below the metering
units, therefore product can easily flow out of the rotors.
If there was a loss of pressure in the tank (lid left open/ incorrectly adjusted lid), the pressure
differential above and below the metering units will not be equal. As a result, product will not easily
flow out of the rotors.
An air pressure gauge is mounted to the front of the machine to monitor air pressure.
Normal operation the gauge should read 0 – 5 mbar.
If the air differential exceeds this value, please check the system for leaks as shown in chapter 6.3.5
