Application fields
The NTA/TZA series of silent axial-flow fans are widely used in heating, ventilation, air conditioning, and refrigeration applications. Depending on the specific equipment structure and intended use, the following mounting options are available: square-panel mounting (F-type), round-duct mounting (G-type), and square-panel mounting with adjustable blades at the front end (FB-type). These fans are designed to meet the requirements of various complex working environments.

A SILENT DESIGN
The wind blade design adopts a curved swept toothed tail wing, combined with bionics and aerodynamic principles, effectively cutting and combing the airflow, thereby reducing noise.

B CTWO MOTOR SCHEMES
NTA(AC): Adopting AC asynchronous motor
TZA(EC): Adopting permanent magnet variable frequency motor

C PROTECTIVE PERFORMANCE
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.

D 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.

Protection method: With thermal protection

Specially customized: Variable pole dual speed: 6/4, 8/6, 10/8, 12/8
