Roof ventilation is an important part of roofing. Proper roof ventilation extends the life of a roof and reduces temperature differential between the roof and the air outside. This roof ventilation allows free flow of air and prevents the entry of water,

A ducted fan reduces losses in thrust from the tip vortices of the fan, and varying the cross-section of the duct allows the designer to advantageously affect the velocity and pressure of the airflow. The versatile duct fans can be used to remove fumes, d
