Slant-wall fans are commonly used for ventilating industrial and agricultural facilities. Their slanted housing helps protect the fan motor and fan blades from rain and falling debris. These fans have shutters on the intake side, which helps minimize turbulence as air moves through the fan. The shutters close when the fans turn off to block out drafts. The fans also have discharge guards that help prevent objects from entering the fan on the discharge side. Belt-drive slant-wall fans are typically quieter and provide more control over the fans' blade speed and airflow than direct-drive slant-wall fans. Belts connect the fans' motors to their fan blades. Belt-drive fans are better suited than direct-drive fans for high airflow (≥ 2000 cfm) or high static pressure (≥ 0.50") applications.

Cone exhaust fans are typically used to ventilate dairy facilities. They have a discharge cone that maximizes airflow and reduces turbulence as air leaves the fan in application where multiple fans are installed next to each other. The fans have shutters on the intake side, which helps minimize turbulence as air moves through the fan. The shutters close when the fans turn off to block out drafts. These fans also have discharge guards that help prevent objects from entering the fan on the discharge side. Belt-drive cone fans allow users to adjust the fans' blade speed and airflow. Belts connect the fans' motors to their fan blades. Belt-drive fans are better suited than direct-drive fans for high airflow (≥ 2000 cfm) or high static pressure (≥ 0.50") applications.
