SEFSD-211 specifications

The Greenheck Fan SEFSD-211 is a high-performance, energy-efficient fan specifically designed for various applications in the commercial and industrial sectors. Renowned for its robust construction and reliability, the SEFSD-211 is engineered to provide optimal airflow while minimizing noise levels and energy consumption.

One of the standout features of the SEFSD-211 is its advanced direct drive motor technology. This system reduces the need for belts and pulleys, leading to lower maintenance requirements and increased efficiency. The direct drive motor also operates at a consistently high performance level, improving the fan's overall reliability and lifespan. The fan is equipped with a totally enclosed fan-cooled (TEFC) motor, ensuring durability in demanding environments.

The SEFSD-211 excels in energy efficiency, achieving high CFM (cubic feet per minute) ratings while operating at lower horsepower. This energy-efficient design not only contributes to reduced operational costs but also meets or exceeds industry regulations for energy performance. Furthermore, the fan is designed to integrate seamlessly with building management systems, allowing for real-time monitoring and control to maximize operational efficiency.

Noise reduction is a critical consideration in building design, and the SEFSD-211 addresses this with its acoustic treatment options. The fan features a sound-dampening design that minimizes vibrations and reduces audible sound levels, making it suitable for applications in noise-sensitive environments like schools, hospitals, and offices.

Another key characteristic of the SEFSD-211 is its versatile installation options. It can be mounted in various configurations, including horizontal and vertical orientations, making it adaptable to a range of fan layouts and airflow requirements. The fan’s compact design allows it to be easily integrated into existing systems without requiring extensive modifications.

Furthermore, the SEFSD-211 is built with materials that endure harsh conditions. The fan housing is constructed from high-quality galvanized steel, and optional coatings are available for additional corrosion resistance. This durability ensures long-lasting performance even in challenging environments, making it an excellent choice for demanding industrial applications.

Overall, the Greenheck Fan SEFSD-211 combines innovative technology with versatility and durability. Its energy efficiency, low noise levels, and adaptability to various environments make it a leading choice for professionals seeking reliable and effective ventilation solutions in commercial and industrial settings.
