SSDFD-155 specifications

The Greenheck Fan SSDFD-155 stands as a significant advancement in the realm of ventilation solutions, primarily designed for commercial and industrial applications. Built with a focus on performance, reliability, and energy efficiency, this model exemplifies Greenheck's commitment to quality and innovation in air movement technologies.

One of the main features of the SSDFD-155 is its direct drive beltless design. This technology minimizes the need for maintenance while maximizing operational efficiency. The direct drive system allows for a compact and lightweight construction, making it easier to install and integrate into various systems. As a result, users can expect quieter operation and reduced energy consumption compared to traditional fan models.

The SSDFD-155 utilizes a backward-inclined centrifugal wheel, engineered to enhance airflow performance. This design helps in moving a large volume of air at lower static pressures, leading to improved energy efficiency. Additionally, the wheel's construction minimizes turbulence, ensuring stable and effective airflow, which is critical in applications requiring precise air delivery.

Moreover, one of the standout characteristics of this fan is its high-efficiency motor option. Greenheck offers variable frequency drive (VFD) compatibility, allowing the fan to adjust its speed based on real-time demands. This flexibility not only conserves energy but also extends the lifespan of the motor, reducing operational costs over time.

Other important features include a robust housing design that withstands various environmental conditions while minimizing vibration and noise. The SSDFD-155 is designed with serviceability in mind; access panels and strategically placed inspection points facilitate easy maintenance without significant downtime.

In terms of versatility, the SSDFD-155 is suited for a variety of applications, including commercial kitchens, industrial processes, and HVAC systems. Its ability to handle high air volumes makes it an excellent choice for facilities requiring efficient air exchange.

In summary, the Greenheck Fan SSDFD-155 combines innovative technologies and robust engineering to provide reliable and efficient performance in diverse settings. With its advanced features, energy-saving capabilities, and versatile applications, it represents a valuable solution for professionals seeking top-notch air movement solutions in their operations.
