Induced fan manufacturers professionals said that the recent lot of consumers are more interested in knowledge induced fan, and want to understand the main principles of its operation, then, today, induced fan manufacturers to work together to share something about the expertise it induced fan . Induced fan built-in high efficiency centrifugal fan, built-in high efficiency centrifugal fan, with a significant low noise, small size, light weight, easy loading (vertical, horizontal may be), easy maintenance features, has been widely used in underground parking complete ventilation field, gymnasium, workshops, warehouses, shopping malls, supermarkets, entertainment venues and other large occasions. However, in the case of faulty installation, noise-induced wind opportunities arise, as well as the emergence of unsafe induced fan failure, there is the emergence of noise, so consumers should pay special attention to the next. The main application of the theory of perturbations induced by the fan from the aerodynamic characteristics of high-speed jet, use a small amount of gas injected to induce and disturbing mix a lot of ambient air, and bring it to a specific target direction. Jet center velocity gradually reduced starting from the nozzle exit point, but gradually increase the width of the jet, the amount of air induced around gradually increasing. On the one hand diluted indoor harmful gas, on the other hand led to indoor air flow, air flow along a preset path travels to the exhaust fan at the exhaust fan inside the room to drain away, in order to achieve good ventilation in the garage.
