LKW series forward-curved-blade double-inlet centrifugal fan with external rotor motor is a special fan for air conditioning system developed by our company which is placed in the air stream, provided with impulse turbines with a large number of narrow, direct-drive blades.
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, air curtain machines and other products, and has been widely used in hotels, hotels, schools, hospitals, factories,refrigerators, cinemas, high-speed rail, urban rail transit, buses, ships and other fields.
LKW series of fans has the following remarkable advantages:
- The external rotor motor is adopted, which is compact in structure, small in size, light in weight and easy toinstall;
- The forward multi wing impeller with high pressure, low noise, high efficiency and low noise is adopted;
- The direction of the air outlet can be specially customized, and the installation form is flexible and convenient;
- Our self-developed matching motors have better reliability and service life than ordinary motors afterwithoptimization of power;
- Our fans can have different power supplies, such as single-phase, three-phase, DC power supply and others. Voltageand frequency can be as the needs of users from different countries;
- Our fans can have different speed modes, such as single-speed, double-speed, three-speed and steplessspeedregulation to meet the needs of users for air volume regulation.
