Double Inlet Blowers, also known as double inlet centrifugal fans, are high-performance air-moving devices designed for various ventilation, cooling, and air handling applications. They feature two inlets that draw air into the fan housing, providing increased airflow efficiency and static pressure capabilities.

1.Product Features:

  • Dual Inlet Design:

Incorporates two inlet openings to efficiently draw air into the fan housing, allowing for increased airflow rates and static pressure capabilities.

  • Centrifugal Impeller Design:

Utilizes backward-curved or forward-curved impellers to generate high-velocity airflow with minimal noise and energy consumption.

  • Robust Construction:

Constructed with durable materials to withstand demanding operating conditions and ensure long-term performance.

  • Versatile Mounting Options:

Can be mounted horizontally, vertically, or at any angle, making them adaptable to different installation requirements.

  • Maintenance-Free Operation:

Designed for hassle-free operation with minimal maintenance requirements.

2.Application Scenarios:

  • HVAC Systems:

Ideal for use in heating, ventilation, and air conditioning systems in commercial buildings, offices, hospitals, and industrial facilities.

  • Cooling Towers:

Critical for cooling applications in cooling towers, evaporative condensers, and air-cooled heat exchangers to dissipate heat and maintain optimal operating temperatures.

  • Air Handling Units (AHUs):

Suitable for integration into AHUs to provide efficient air circulation, filtration, and ventilation.

  • Industrial Ventilation:

Used in factories, warehouses, and production facilities to exhaust fumes, dust, and other airborne contaminants.
