A fan wall uses many specially designed, high-efficiency, small-diameter, direct-driven plenum fans, which are mounted in an array within an air handler's air-way tunnel.. Other design features included component portability, a smaller AHU footprint, and, perhaps most importantly, redundancy and reliability that was not achievable with. 3282 How Fan Walls or Fan Arrays Work. Fan walls are fans configured in stackable or wall mounted modules that can be designed in various arrays to form a larger fan system. They have a host of benefits over traditional fans used in the HVAC industry that we'll cover in this article.

FANWALL ® Systems Fan Systems for New Construction and Replacement Applications Using our FANWALL Systems to replace aging, end-of-life fans in existing air handlers can be the most cost-effective solution for avoiding the cost and business disruption of an air handler failure while delivering energy savings as high as 40%. Product Debut in the U.S. March 2003 Product Function and Application According to the Manufacturer FAN WALL TechnologyTM is Huntair's name for a new way of assembling custom air handling units using an array of smaller fans to replace a traditional single large fan. Learn how Fan Walls are used in the renovation of existing air handlers or built-up systems. Learn how they are controlled and how they are built. See how fa. Advanced Engineered Design Variable cube dimensioning allows the selected array to more closely fit air tunnel dimensions, so that the fans produce a uniform piston of air over the entire coil surface for optimal heat transfer and even filter loading.

a preferred design alternative to larger single or dual fan systems. A New Look at Motor Speed Motor operating speed is a design parameter that often results in challenges to a designer's "comfort zone" when selecting fan drive systems. VFDs have made it possible to run motors at a range of speeds and design applications A modern fan array system performs at peak energy efficiency and makes buildings as green as possible, while simultaneously offering high standards of indoor air quality. Single vs. multi-fan systems. Legacy air handlers are usually large, single-fan rotors whose benefits are often outweighed by how difficult they are to run efficiently and upkeep. Fanwall Technology Using a FANWALL system to replace older, end of life fans in existing air handlers can be the most cost-effective solution for avoiding the cost and business disruption of an air handler failure, while delivering energy savings as high as 40%. FANWALL backdraft damper seals off the fan to prevent recirculation of system air with very little leakage if a cube is taken out of operation. When open, the damper's aerodynamic design ensures almost zero-system effect. Stringent balance requirements and sturdy components in each FANWALL cube eliminate internal vibration and the need to.

Designed to inspire. Contemporary wall fan design Seasoned Solid wood blades Ideal for Commercial and Hospitality spaces Suitable for use in Indoor location Can be mounted on Ceilings Preferred by Architects and Interior designers Standard finish and sizes Matt Black with Solid teak wood blades (Walnut matt) An EC Fan Array is a wall of EC motorized impellers that operate in parallel. When identical fans operate in parallel, the total airflow rate of the system is the product of an individual fan's airflow rate times the number of fans in the array. For example, consider a system with a design point of 20,000 cfm at 2.75 in. wg.
AireWall™ is a new low energy, high density cooling solution for mission-critical environments. This new range of computer room air handlers (CRAHs) is desig. Utilizing a modular design, FANWALL arrays accommodate a wider range of air handler aspect ratios with unmatched design flexibility for indoor/outdoor applications. This results in a reduced footprint by as much as 33%; leading to more interior space for other uses.

The basic design will consist of an outside wall with cooling units and a fan wall inside the facility. There will be a five-to-six-foot plenum between the two walls that will be filled with cold air. Abdel's blog post also has a good summary of the industry's perennial data center cooling debate on raised floor versus overhead cooling. However, as variable-frequency drives (VFD) have become more cost effective and reliable, direct-drive fans have become more popular, primarily with plenum fans. With a direct-drive plenum fan (Figure 1), the fan wheel is mounted directly on the motor shaft. With no belts or sheaves, and fewer bearings, direct-drive fans are more reliable and.
