You will need a fan that is capable of ventilating structures in your response area. Airflow performance is determined by impeller design, impeller diameter and input power. We engineer each impeller for the motor its built with. For our electric fans, we even build the motors – giving us full control to meet our performance targets. We manufacture the most efficiently powerful fan impellers in the industry.
Increasing a fan's size or input power will increase the airflow. However, a large fan powered by a large motor will weigh more and take up more compartment space.
