In the pharmaceutical industry, industrial vacuum cleaners are products developed to meet the continuous dust removal needs in industrial settings. They use a vortex air pump, which is similar to a large gas turbine impeller. When the impeller of the vortex pump rotates, the air between the impeller and the blades is subjected to centrifugal force, moving towards the edge of the impeller, where the air enters the annular space of the pump body and then returns to the impeller. The process repeats in the same manner from the starting point of the blades. Because the air is accelerated uniformly, the circulating airflow generated by the rotation of the impeller allows the air to exit in a spiral form, resulting in air leaving the pump with extremely high energy (the pressure it generates is 12-17 times that of a centrifuge with the same rotational speed and diameter). Additionally, it features ease of operation, flexible mobility, wide applicability, and safe and reliable performance, making it particularly suitable for industries such as pharmaceuticals, chemicals, and food. 1. The NT300 series is a vacuum cleaner for powder removal in the pharmaceutical industry launched by Nake, equipped with a turbine motor that can operate continuously for 24 hours. 2. It has a high-precision filtration effect, using a dual-layer high-efficiency filter with a filtration precision of 0.3um and an efficiency of up to 99.98%. The first layer is a dust protection filter; the second layer is a HEPA high-efficiency air filter.
