In order to maximize airflow from your Paxton blower system, our application engineers utilize both blower performance curves and air delivery device resistance curves to properly size a Paxton blower system. Every blower has a peak efficiency range where the blower should be operated at to ensure maximum power, peak efficiency, and maximum blower life. Normally, air delivery devices are selected first then, based on what air delivery devices were selected, the blower is selected to power the chosen air delivery devices.
When pairing air delivery devices with a blower, both size and quantity matter. If multiple
air delivery devices are chosen and the blower does not have enough horsepower, the system will underperform and could draw more current that than the motor is rated for causing the motor to fail prematurely. On the other hand, using too few air knives with an oversized blower will cause excessive heat buildup, effectively shortening the life of the blower head. Both of these scenarios will result in the blower operating outside of its peak efficiency range, therefore reducing the efficiency and shortening the life of the blower.
If a customer has a question about adding an air knife to their system, ask our application engineers if their current Paxton blower can handle that addition.
