Abstract
The invention provides a pneumatic conveying system for an agricultural product applicator, which system comprises multiple fans configured to serve separate boom sections of the applicator to more efficiently conduct airflow with respect to each section. In aspects of the invention, multiple centrifugal fans of the same or similar size can be used, or multiple centrifugal fans of various sizes can be used, such as one or more larger fans and one or more smaller fans. Exemplar aspects could include three small or medium sized centrifugal fans, four small or medium sized centrifugal fans, and five small or medium sized centrifugal fans, thereby allowing the system to raise outlet air pressure at an elevated flow. Another aspect of the invention could include configuring one fan to supercharge another fan, in series, also allowing the system to raise outlet air pressure at an elevated flow.
