Sizing a blower for an air knife application is not a simple process. The velocity of air required depends on how fast the material to be dried passes under the air knife. With a blower as an air source, the higher pressure developed by the blower will increase the air temperature, resulting in a better drying process. Designing of equipment should include work to minimized air friction losses in plumbing connecting the air knife to the blower. It is best to use a larger pipe size than the air source discharge. The best method to determine the air consumption of an air knife is to test it. To increase the airflow exiting an air knife, the pressure must be increased four times.
