Product Description

LKWG SERIES DUCT FAN WITH EXTERNAL ROTOR MOTOR

LKWG series duct fan with external rotor motor is a special fan for air conditioning system developed by our company. Its shape is similar to a section of air duct. It adopts square inlet and outlet flange. It can be directly installed in the ventilation duct without ground installation foundation. It is very convenient to install, operate and maintain.

The fluid model of this series of fans has been optimized by CFD advanced technology, which not only increases the output pressure, but also reduces the noise and improves the efficiency. It has the characteristics of energy saving and low noise. It is especially suitable for supporting various air conditioning, refrigeration, purification, fresh air units and other products, and has been widely used in hotels, schools, hospitals, factories, refrigerators, cinemas, buildings and other fields.

LKWG series of fans has the following remarkable advantages:

1. Duct shape is adopted, which is compact in structure, small in size, light in weight and easy to install;

2. The forward multi wing impeller with high pressure, low noise, high efficiency and low noise is adopted;

3. Our self-developed matching motors have better reliability and service life than ordinary motors after with optimization of power;
