University of Nebraska-Lincoln Extension: Historical Materials
This publication describes the most common types of ventilation fans and compares their physical and performance characteristics.
Two general types of ventilation fans are commonly used for agricultural applications. Each type has many different blade diameters, materials, blade shapes, speeds, and motor horsepowers available. The desired airflow rate and the resistance to airflow through the ventilation system, or static pressure capabilities, are the two primary considerations when selecting a ventilation fan. Other considerations include maintenance requirements, noise levels, and energy efficiency.
