Pressure Drop Data

FSD-331

This pressure drop testing was conducted in accordance with AMCA Standard 500-D using the three configurations shown. All data has been corrected to represent standard air at a density of .075 lb/ft3(1.201 kg/m3).

Actual pressure drop found in any HVAC system is a combination of many factors. This pressure drop information along with an analysis of other system influences should be used to estimate actual pressure losses for a damper installed in a given HVAC system.

AMCA Test Figures

Figure 5.3 Illustrates a fully ducted damper. This configuration has the lowest pressure drop of the three test configurations because entrance and exit losses are minimized by straight duct runs upstream and downstream of the damper.

Figure 5.2 Illustrates a ducted damper exhausting air into an open area. This configuration has a lower pressure drop than Figure 5.5 because entrance losses are minimized by a straight duct run upstream of the damper.

Figure 5.5 Illustrates a plenum mounted damper. This configuration has the highest pressure drop because of extremely high entrance and exit losses due to the sudden changes of area in the system.

This makes the FSD-331 an ideal choice for noise-sensitive areas, such as schools, hospitals, and residential buildings.

The FSD-331 also boasts a direct-drive motor system that eliminates the need for belts and pulleys. This design not only reduces maintenance requirements but also enhances reliability, as there are fewer components that can wear and fail over time. The fan’s motor is designed to operate efficiently across a wide range of speeds, allowing users to adjust airflow as needed to accommodate varying ventilation demands.

Energy efficiency is a key characteristic of the FSD-331. It is available with various motor options, including high-efficiency models that comply with energy standards, helping building owners save on energy costs while reducing their carbon footprint. Additionally, the fan can be integrated with advanced control systems, such as variable frequency drives (VFDs), to further optimize performance and energy usage.

The FSD-331 is built to withstand challenging environmental conditions, thanks to its durable materials and weather-resistant features. Its housing is constructed from heavy-gauge steel, and options for protective coatings are available to enhance corrosion resistance. This durability ensures that the fan remains operational in harsh weather, making it suitable for rooftop installations and outdoor use.

The installation of the FSD-331 is straightforward, and it offers flexibility in mounting configurations, including horizontal and vertical orientations. This adaptability makes it easy to incorporate into existing systems or new construction projects.

In summary, the Greenheck Fan FSD-331 is an innovative solution for effective ventilation, featuring a high-performance design, energy-efficient operation, and robust construction. Whether for industrial processes, commercial buildings, or other applications, the FSD-331 is engineered to deliver reliable performance and significant operational savings.
