Fan Overview
3-Series Low Noise Energy Saving Mixed Flow Ventilator and (-) Series High Temperature Smoke Exhaust Mixed Flow Ventilation The fan is a new type of fan between the axial flow fan and the centrifugal fan. It has the dual characteristics of the high pressure of the centrifugal fan and the large flow rate of the axial flow fan, and has the characteristics of high efficiency, energy saving, low noise, and easy installation.
-Series ventilators are novel in design, compact in structure, small in size, light in weight, and easy to install. Compared with old-fashioned centrifugal ventilators, they can save energy. When the rotation speed is less than B, the noise is lower than B. The fan is connected to the pipe or installed When inside the air conditioner (fan) box, the noise is less than B. It can replace the following medium and low pressure centrifugal fans and is widely used in ventilation, air conditioning and dust removal of industrial and civil buildings.
(-) series high-temperature smoke exhaust fans are derivatives of the series of high-temperature smoke exhaust fans. They not only have the characteristics of 3-type ventilators, but also can operate normally at an ambient temperature of about 3°C. It has the dual functions of ventilation and high-temperature smoke exhaust. It is an ideal fire-fighting supporting facility in tunnels, subways, underground shopping malls, underground warehouses, underground garages and other places. It is very popular among design institutes and users.

Fan features
The fan is mainly composed of impeller, casing, air inlet collector, guide vane, motor and other components. The impeller adopts several spatially twisted blades with meridional acceleration characteristics and is welded to the hub. It has undergone dynamic balance verification and overspeed testing to ensure good aerodynamic performance.
The casing adopts a cylindrical shape and is integrally connected with the air collector with silencing function. The outlet is equipped with a guide plate to ensure uniform air flow distribution and stable pressure. The (-) type fan has the motor external circulation cooling system structure of a series of fire smoke exhaust fans, which is suitable for fire smoke exhaust.
