Induced fan

The induction fan is a new type of fan designed according to the concept of high-speed jet induced ventilation. The non-duct induced ventilation subsystem composed of multiple fans can be combined with a supply fan and an exhaust fan to form an entire ventilation and exhaust system. Its principle of operation is to induce fresh air or treated air outside the system by designing and appropriately arranging multiple induced blower nozzles to direct it to the required area under the condition of no wind pipe. To achieve the best indoor airflow organization in order to achieve efficient and economical ventilation effect. When using a non-ducted jet induced ventilation system, the costs of designing, manufacturing, installing ductwork and other ancillary projects can be saved. This part of the cost is much more expensive than the induction turbine used, and the entire level is a ventilation duct. The supply air blower and the exhaust fan need much less air pressure than when using a duct. This allows the use of a fan with a lower air pressure for a large amount of air to reduce the required power and significantly reduce the operating costs and investment costs. When the exhaust fan stops running, the induced fan can still be operated and play the role of local ventilation. Induction fan built-in high-efficiency centrifugal fan, with obvious low noise, small size, light weight, easy lifting (vertical, horizontal can be), simple maintenance features, has been widely used in underground parking lot, gym, workshop, warehouse , shopping malls, supermarkets, entertainment venues and other large places of ventilation.
