What is a 14 inch 355mm flexible duct?
Air moves through ducts and enters rooms through diffusers and grilles. Louvers let fresh air in and exhaust air out while keeping rain and sand outside. Hoods, impeller fans and attenuators complete kitchen and ventilation systems.
Size each part for the airflow. Therefore, match diffusers and louvers to the design airflow and keep velocities low for quiet operation.
