Rectangular Duct Fan with External Motor
Rectangular Duct Fans with External Motors are specifically engineered for the extraction of grease-laden, humid, elevated-temperature, and heavily contaminated air in commercial kitchens and industrial facilities. By positioning the electric drive motor entirely outside the airstream, the system shields critical electrical components from corrosive vapors and heat, ensuring maximum operational reliability and an extended equipment lifespan.
Combining excellent environmental adaptability with smart control units, this series delivers both cost competitiveness and innovative engineering. With airflow capacities up to 6,000 m³/h, direct rectangular flange integration, and a dedicated access door, it facilitates rapid installation and low-maintenance operation even within restricted false-ceiling voids.
Key Features
- Motor Out of Airstream: Drive motor completely isolated from hot, greasy, and aggressive exhaust airflows
- High Airflow Delivery: Robust volumetric capacities up to 6,000 m³/h with superior static pressure generation
- Direct In-Line Mounting: Standardized rectangular flange profiles for seamless integration into existing ductwork
- Smart Control Ready: Compatible with variable frequency drives (VFD), speed switches, and central BMS networks
- Heavy-Duty Construction: Corrosion-resistant galvanized steel housing with a dynamically balanced radial impeller
- Service-Friendly Design: Quick-release access panel allowing impeller cleaning without dismantling the duct system
Application Fields
- Commercial kitchens, restaurants, hotel catering facilities, and canopy exhaust systems
- Ventilation duct lines carrying high moisture, grease aerosols, and heavy odors
- Shopping centers, food courts, and food production plants
- Industrial workshops, paint booths, and chemical vapor extraction ductwork
- All rectangular duct runs requiring external motor isolation and high extraction reliability
