Basic parameters
K3G450-PB29-L1 is a centrifugal fan. Its rated voltage is 400V, which enables it to operate stably in common industrial power environments. The size of the fan is 450 mm, which is reasonable in terms of space occupation. It can meet certain air volume and air pressure requirements without occupying too much space.
In terms of air volume, its maximum air volume can reach 9035m³/h. Such a large air volume means that it can quickly replace air in a large area of space. For example, in a large industrial workshop, it can quickly discharge the dirty air in the workshop, introduce fresh air, and improve the air quality of the workshop.
The maximum pressure is 1749Pa. The high wind pressure enables the fan to overcome the resistance in the ventilation duct and transport the air to a longer distance. Even if the ventilation duct is long or there are certain bends, the normal circulation of air can be guaranteed.
The input power is 6800W. The higher power provides power guarantee for the efficient operation of the fan. The speed is 2800rpm, and the stable speed ensures that the fan can continuously and stably output air volume and air pressure.
Design Features
From a design perspective, K3G450-PB29-L1 has unique advantages. It adopts advanced aerodynamic design, which enables the fan to convert electrical energy into wind energy more efficiently during operation. The design of the impeller has been carefully optimized to minimize air resistance and improve the output efficiency of air volume and air pressure.
The fan casing is made of high-quality materials with good strength and corrosion resistance. This enables the fan to be used for a long time in harsh industrial environments and reduces damage to the fan caused by external environmental factors. At the same time, the design of the casing also takes into account the need for heat dissipation, which can dissipate the heat generated by the motor in time to ensure the normal operation of the motor.
In terms of manufacturing technology, the fan adopts high-precision processing technology, and the assembly accuracy of each component is high, which reduces vibration and noise during operation. Although the noise parameter is marked as not applicable, in actual operation, due to its good design and manufacturing process, the noise level is relatively low and will not cause obvious interference to the surrounding environment.
Application Advantages
Due to its excellent performance and characteristics, K3G450-PB29-L1 is widely used in many fields. In industrial plants, it can be used for ventilation, keeping the air in the workshop fresh, and providing a good working environment for workers. In commercial buildings, such as shopping malls, hotels, etc., it can be used for ventilation of central air-conditioning systems to ensure the circulation and quality of indoor air. In some places with high requirements for air quality, such as hospitals and laboratories, it can also play an important role to ensure the cleanliness and circulation of air.
In summary, K3G450-PB29-L1 centrifugal fan has become a leader in ventilation equipment in the industrial and commercial fields with its excellent parameters, unique design features and wide application advantages. Whether in terms of performance or reliability, it can meet the needs of users and bring users efficient and stable ventilation solutions.
