Extruded BACKDRAFT DAMPER

ES-40 SERIES

Horizontal Mount Vertical Airflow Down

Application and Design

The ES-40 series is a horizontally mounted backdraft damper that is designed to allow vertical airflow down and prevent reverse airflow. The damper is opened by air pressure differential and closed by gravity. Standard models include adjustable counterbalance weights to assist closing.

ES-40 Series specifications

The Greenheck Fan ES-40 Series represents a pinnacle in commercial and industrial ventilation technology, designed to meet the diverse needs of modern facilities. Engineered for efficiency and performance, the ES-40 Series combines powerful airflow capabilities with cutting-edge features.

One of the standout characteristics of the ES-40 Series is its high-efficiency motor options. These motors are designed to reduce energy consumption while maintaining optimal performance, aligning with modern sustainability goals. By utilizing electronically commutated motors (ECM), the series can operate at variable speeds, offering flexibility that traditional AC motors cannot match.

The ES-40 Series also includes advanced airflow design that maximizes performance while minimizing noise levels. This is especially beneficial in environments where quieter operation is essential, such as offices, schools, or healthcare facilities. The fans' uniquely engineered blades and housing work together to enhance airflow dynamics, making them efficient for ducted or ductless applications.

Durability and robust construction are key attributes of the ES-40 Series. The fans are built with high-quality materials designed to withstand challenging operating conditions, including extreme temperatures and corrosive environments. This durability translates into longer lifespan and reduced maintenance costs—a significant advantage for building owners and operators.

Another critical feature of the ES-40 Series is its flexibility in installation. With a variety of mounting options and customizable configurations, users can tailor the setup to fit their specific requirements. The fan's versatility makes it suitable for a wide range of applications, including commercial kitchens, industrial manufacturing, and ventilating large spaces.

Additionally, Greenheck has integrated advanced technology into the ES-40 Series through options like integrated controls and smart sensors. These features enable real-time monitoring and adjust airflow based on occupancy or specific demands within a facility. Such innovations contribute not only to energy savings but also improve indoor air quality.

In summary, the Greenheck Fan ES-40 Series encapsulates a combination of efficiency, durability, and advanced technology, making it an ideal choice for various ventilation needs. Whether in a commercial or industrial setting, the ES-40 Series stands out as a reliable solution that meets contemporary challenges in airflow management.
