The wind blade design adopts a curved swept toothed tail wing, combined with bionics and aerodynamic principles, effectively cutting and combing the airlow, thereby reducing noise.
TWO MOTOR SCHEMES
NTA(AC): Adopting AC asynchronous motor
Protection method: with thermal protection
The motor protection level is IP66, and the mesh cover prevents external foreign objects from entering, improving the reliability and service life of the fan.
DIRECT INSTALLATION
The motor is directly connected to the fan blades, reducing energy loss in the transmission process and improving efficiency. More compact structure and easier installation.
Variable pole dual speed: 6/4,8/6,10/8,12/8
Our axial flow fans adopt an innovative airfoil blade design and low-noise, space-saving motor technology, ensuring smooth and powerful airflow delivery, extremely low operating noise, and higher energy efficiency ratio. These systems are particularly suitable for places requiring continuous quiet ventilation, with significant optimization in energy consumption and noise levels compared to traditional ventilation solutions.
As part of our global vision, FJDIAMOND is expanding its service network to over 80 countries, offering professional pre-sales consultations, reliable after-sales support, and localized technical assistance. We uphold the highest standards of quality and customer satisfaction, guided by our core principle: “Quality Assurance and Owners’ Satisfaction.”
