Centrifugal Blower Fan Applications

The fresh air system of centrifugal fan is based on the principle of sending fresh air to the indoor with special equipment on one side of the closed room, and then discharging it from the other side by special equipment to the outside, and the principle of "fresh air flow field" will be formed indoors, so as to meet the needs of indoor fresh air ventilation. The implementation scheme is: the use of high-pressure head, large-flow and low-power DC high-speed brushless motor to drive the centrifugal fan, relying on mechanical strength to supply air from one side to the room, and the other side with a specially designed exhaust fresh fan to the outdoor discharge method to force the formation of a fresh air flow field in the system. At the same time of air supply, the air entering the room is filtered, disinfected, sterilized, oxygenated, and preheated (winter). When the exhaust air passes through the main engine, heat recovery and exchange with the fresh air, and most of the recovered energy is sent back to the room through the fresh air. Borrowing a large-scale solution to form a clean space, ensure that the air entering the room is clean. In this way, the purpose of indoor air purification environment is achieved.
