Modular fan array air handler system from HUNTAIR

FANWALL TECHNOLOGY originated from HUNTAIR® ceiling grid systems used in cleanroom applications. The smaller fans and motors distributed throughout the grid are ideal for providing the even airflow distribution required for a cleanroom environment, a compact footprint for ceiling mounting, as well as redundancy and easy serviceability to minimize revenue risk associated with downtime.

These same benefits can also be applied to any air handler system, particularly where a critical failure would result in significant risk to capital equipment or revenue losses. However, the characteristics and constraints of an air handler cabinet differ from a cleanroom environment, requiring significant R&D before the concept would become the reality of FANWALL TECHNOLOGY. In doing so, HUNTAIR examined every aspect of the individual fan cubes and their interaction together—throwing out the book on conventional fan metrics to design a completely new system optimized for fan array applications, including:

  • 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. Fans are available in 7 sizes from 10 to 22 inches to closely match airflow requirements. 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®) to minimize sound and vibration.
  • Damper selections to minimize pressure drop and block-off plates that eliminate backdraft air in fans that are off.
  • Control algorithms to optimize performance in variable airflow applications.

Many of these items are patented or patent pending.
