PERFORMANCE
The Model 11-62 low-noise, multi-vane centrifugal fan was developed to meet the evolving needs of the air purification industry and the requirements for environmental noise reduction. Its design employs a multi-objective optimization approach—balancing parameters such as noise levels and aerodynamic efficiency—and features a widened volute casing to achieve optimal overall performance. The fan offers excellent aerodynamic characteristics, delivering higher airflow for its size class. With an impeller that has undergone rigorous dynamic balancing, the unit operates smoothly with low noise, minimal vibration, and a long service life. It is widely used for kitchen exhaust and ventilation in public facilities such as institutional canteens, hotels, restaurants, and eateries, and is also suitable for integration into production machinery for the grain processing, chemical, and plastics industries.
The company follows the service principle of “user first” and has set up a professional technical support team dedicated to serving every customer with care.
