By way of inducing fan-induced air between then passed, because it was the wind itself, the amount of low Shanghai pipeline induced fan, so often is widely used in public facilities were then dead air for local cleanup with the mix, allows local air quality improved. Due to specially constructed with the induction principle ducted fan induced fan manufacturers, so it tends to allow for processing fresh outdoor air, and then under no duct work conditions required for it to be able to effectively ensure that the indoor area The airflow can be such a ventilation Dada to the best effect. At present, some large car park, gymnasium, workshop with warehouse and shop often need to be ventilated Hunan pipeline induced fan, they are often inseparable from the induction 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 lifting (vertical, horizontal may be), easy maintenance features, has been widely used in underground parking complete ventilation field, gymnasium pipeline induced fan, workshops, warehouses, shopping malls, supermarkets, entertainment and other large occasions. The main application of the theory from the fan-induced perturbations in the high-speed aerodynamic characteristics of the jet, use a small amount of gas injected to induce and disturbing mix a lot of ambient air, and bring to a specific target direction. Jet center velocity gradually reduced from the nozzle exit point onwards, but the jet width gradually increasing the amount of air induced by the surrounding gradually increasing. On the one hand dilute indoor harmful gas, on the other hand led 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. Hunan pipeline induced induced fan ducted fan _ _ Yaofeng Zhen Lu right Tuen by inducing fan Limited. Lu right Tuen induction fan Limited (www.dzydfjjg.com) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and continuous improvement will lead Yaofeng Zhen innovative ideas into the brilliant and you work for a better future!
