Custom fan wheel designs and inlet cones to optimize airflow efficiency and minimize turbulence. The fan wheels are AMCA certified at 72% efficiency, which is 7% to 9% higher than comparably sized fans offered by others and equivalent to much larger fans. Multiple fan wheel sizes and motor combinations to provide flexibility in meeting airflow requirements and create an even piston of air within the constraints of the air handler cabinet dimensions. Expanded horsepower (hp) motor selections provide the ability to closely match the design hp for peak efficiency throughout the operating range of the air handler. A robust cube design and silencing system (called a Coplanar Silencer), minimize sound and vibration. Damper selections to minimize pressure drop and block-off plates that eliminate back draft air in fans that are off. Control algorithms to optimize performance in variable airflow applications.
