The Dock Fan featured Nozzle had registered a Chinese patent。
The Nozzle on Dock Fan can generate a long throw airflow by speeding and pressurizing the airflow.
The normal length of the logistic cargo box is more than 17.5 meters, the airflow by ordinary axial fan can only be throwed to 5 meters inside. In hot and muggy summer days, the temperature inside the box is nearly 50°C which is impossible for loading or unloading operation. Besides, the axial fan would need more than half an hour to exhaust hot air.
The Dock Fan featured Nozzle can generate massive high speedy and pressured long throw airflow which can reach to the end of box to speed up the ventilation in a few minutes to improve the productivity and working environments substantially.
Some major logistic companies had installed the Dock Fan at their loading dock and satisfied with the performance.
