AC Backward Centrifugal Fans, also known as Plug Fans, are high-performance air-moving devices designed for various ventilation, air conditioning, and air handling applications. They feature a backward-curved impeller design and are directly driven by an external motor, making them compact, efficient, and versatile for both supply and exhaust air applications.

1.Product Features:

  • Backward-Curved Impeller Design:

Utilizes a backward-curved impeller configuration, which provides efficient airflow performance with low noise levels and moderate to high static pressure capabilities.

  • Direct Drive Configuration:

Mounted directly onto the motor shaft without the need for a transmission or belt drive system, resulting in reduced maintenance requirements, increased efficiency, and compact installation.

  • High Airflow Rates:

Capable of delivering high volumes of air at relatively low speeds, making them suitable for applications requiring uniform air distribution and energy efficiency.

  • Compact Design:

Space-saving design allows for flexible installation in various HVAC systems, air handling units, and ducted ventilation systems with limited space constraints.

  • Robust Construction:

Built with durable materials to withstand continuous operation and harsh environmental conditions, ensuring long-term reliability and performance.

2.Application Scenarios:

  • HVAC Systems:

Used in heating, ventilation, and air conditioning (HVAC) systems to supply or exhaust air from buildings, ensuring proper air circulation, temperature control, and indoor air quality.

  • Air Handling Units (AHUs):

Integrated into air handling units to distribute conditioned air throughout buildings, providing comfort cooling or heating to occupants.

  • Commercial Kitchen Exhaust:

Employed in commercial kitchen exhaust systems to remove smoke, grease, and odors from cooking areas, maintaining a clean and safe working environment.

  • Industrial Ventilation:

Utilized in factories, warehouses, and production facilities to exhaust hot air, smoke, fumes, and other airborne contaminants, ensuring worker safety and equipment performance.
