Duct fans

Key Features and Functions:

1. Inline Design: Duct fans feature a compact, inline design that allows them to be installed directly within ductwork, typically mounted in-line with the ducts to facilitate airflow through the ventilation system.
2. Axial or Centrifugal Fan Types: Duct fans are available in both axial and centrifugal fan configurations, offering different airflow characteristics and pressure capabilities to suit various ventilation requirements:
   • Axial Duct Fans: Axial fans generate airflow parallel to the fan’s axis of rotation, providing high airflow rates at low to moderate static pressures, suitable for applications requiring high-volume ventilation, such as exhaust ventilation in commercial kitchens, bathrooms, and industrial facilities.
   • Centrifugal Duct Fans: Centrifugal fans create airflow perpendicular to the fan’s axis of rotation, delivering higher static pressure and increased airflow resistance capabilities, making them suitable for ducted HVAC systems, air filtration, and ventilation in large buildings, cleanrooms, and ducted air conditioning systems.
3. Variable Speed Control: Many duct fans feature variable speed control options, allowing users to adjust the fan speed and airflow rate to meet specific ventilation requirements, optimize energy efficiency, and reduce noise levels.
4. Quiet Operation: Duct fans are designed with noise-reducing features such as aerodynamic fan blades, vibration dampening mounts, and insulated housings to minimize noise levels during operation, ensuring quiet and unobtrusive ventilation in residential and commercial environments.
5. Energy Efficiency: Energy-efficient duct fans utilize advanced motor technologies, such as EC (Electronically Commutated) motors or high-efficiency AC motors, to reduce energy consumption and operating costs while maintaining reliable performance and airflow.
6. Easy Installation and Maintenance: Duct fans are designed for easy installation and maintenance, typically featuring lightweight construction, standardized mounting flanges, and accessible service panels for quick and hassle-free installation, inspection, and maintenance.
7. Durable Construction: Duct fans are constructed from durable materials such as galvanized steel, aluminum, or corrosion-resistant plastics to withstand harsh environmental conditions, high temperatures, and corrosive atmospheres encountered in ventilation systems.
8. Integration with Ductwork: Duct fans are seamlessly integrated into ductwork systems, featuring duct connections or flanges that allow for easy connection to existing ducts, vents, or exhaust outlets.
