ADA Series - Double Inlet Centrifugal Fans - Airfoil Wheels

 

Overview :

The ADA series is a DIDW centrifugal fan with high efficiency non-overloading airfoil impeller. The fans are suitable for supply or exhaust applications in commercial, process and industrial HVAC systems.

Sizes of this series are in accordance with AMCA Standard 99-16.

The full ADA series is AMCA certified to Air, Sound and FEG.

The ADA series is available in types S, C, T, X and Z.

The operating limit of different fan types of the ADA series is set according to the requirement of Class 1, 11 and 111 limit as defined in AMCA Standard 99-16.

The airfoil blade induces a smooth airflow across the blade surface, reducing turbulence and noise within the wheel. This results in increased in static efficiency and reduced in overall sound levels.

Application range of the airfoil wheel is from approximately 50 to 85% wide open airflow. The airfoil fan surges at a greater percentage of wide open airflow, placing the surge line farther to the right on the fan curve.

Static efficiencies as high as 86% can be achieved with airflow fans.
