  • AC Centrifugal Fans
    In fields such as industrial automation, HVAC, and electrical equipment, AC centrifugal fans, as the core power units for heat dissipation and ventilation, play a critical role in ensuring stable equipment operation, optimizing ambient temperature and humidity, and improving system efficiency. AC centrifugal fans are not simply "ventilation tools," but rather core components for temperature and airflow management in industrial systems. From the high air pressure of centrifugal fans, to the high air volume of axial flow fans, to the compact design of cross-flow fans, each model is optimized for specific scenarios, providing users with "efficient, stable, and easy-to-maintain" ventilation and heat dissipation solutions.

  • EC Centrifugal Fans
    The EC centrifugal fan integrates electronic commutation technology with a centrifugal airflow design. It's more than a simple "motor + fan" combination in the traditional sense. Instead, it uses an electronic control system to directly drive the motor, which in conjunction with a centrifugal impeller achieves air pressure boosting and delivery. Its core feature is electronic commutation instead of mechanical commutation, offering advantages such as high energy efficiency, precise temperature control, and low noise. Due to its high static pressure, high efficiency, and precise temperature control, the EC centrifugal fan motor is primarily designed for applications requiring directional, high-pressure, and stable airflow, and is widely used in air conditioning, fresh air systems, refrigeration equipment, and cabinet cooling.

  • Box-Type Fans
    A box-type fans is a fan with a box-shaped structure. The fan and related components are integrated into a box-shaped casing. This design offers several advantages. It effectively reduces noise during operation, as the box structure helps contain and muffle fan noise. The casing protects the internal fan components, preventing dust, debris, and other external factors from interfering with fan operation, thereby improving the fan's durability and reliability. Box-type fans are widely used in various ventilation and air conditioning systems, such as commercial buildings, industrial facilities, and residential spaces. They can effectively move air while maintaining a relatively quiet and safe operating environment.

  • Blower Impeller
    A blower impeller generally consists of blades, a hub, and other components. When the impeller rotates at high speed, driven by a power source such as a motor, the blades push air or other gases, giving them kinetic energy and generating a directional flow, thereby transporting and pressurizing the gas. Centrifugal impellers are a common type. During rotation, gas enters the center of the impeller, experiences centrifugal force from the blades, and is flung toward the impeller's edge before exiting the blower, completing the gas transport process.

  • Mini Size Centrifugal Fans
    Mini size centrifugal fans are compact and suitable for installation in space-constrained environments. They generate airflow by creating centrifugal force through the high-speed rotation of their impellers, accelerating the air outward. These fans are available in various sizes, including diameters of 133mm, 146mm, and 160mm. They are CE certified to Directive 2006/42/EC and comply with relevant EU machinery safety standards. They have a wide range of applications, including electronic equipment cooling, small ventilation systems, and mechanical equipment cooling, where localized ventilation and heat dissipation are required. Their compact size facilitates integration into various devices and systems.

  • Backward Centrifugal Fans
    Backward centrifugal fans refer to a type of centrifugal fan where the blades of the impeller are curved backward relative to the direction of rotation.In these fans, when air enters the impeller, it is accelerated and then discharged in a direction that is more towards the tangential direction of the fan casing. Compared to other types of centrifugal fans , backward centrifugal fans typically have higher efficiency, better aerodynamic performance, and can operate more stably under a wider range of air volume and pressure conditions. They are commonly used in various industrial and commercial applications that require efficient air movement, such as ventilation systems, air conditioning systems, and industrial processes where air needs to be moved with relatively high pressure and efficiency.

  • Single Inlet Centrifugal Fans
    Single inlet centrifugal fans are ventilation devices that use centrifugal force to transport air or gas. Air enters through a single inlet and is pushed outward by a rotating impeller, increasing pressure and flow rate. Structurally, the impellers feature forward-curved and backward-curved blades, typically made of galvanized steel. The motors are AC and EC, equipped with various features including thermal protection. IP54 and IP55 protection levels are common, with Class F insulation. The casing is made of corrosion-resistant steel, some with a polymer coating. They offer high performance, handling large air volumes in a small space, adjustable speed and noise control, and dynamic balancing for stable, vibration-free operation. They are used in HVAC systems for indoor air conditioning, industrial process ventilation, equipment cooling, and other ventilation applications, such as commercial kitchen exhaust and cleanroom ventilation.
