inline duct fans
Performance introduction
GDF series global duct fan is a new fan designed depending on advanced technology both domestic and abroad. The overall dimensions of air let and air outlet are the same. The fan connects with air duct directly, as installation instruction shows. Pipeline design and installation costs are greatly saved. According to aerodynamics can lessen vibration and reduce noise the new shell and the paddle-wheel designed. GDF series global duct fan is suitable for the hotel, the guesthouse, the senior hall, supermarket, storage and the bathroom to supply, exhaust, exhaust, make-up and filter air.
The weight of single global duct fan is not exceeding 10kg, which is possible for one person to move the global duct fan and convenient to install.

1）Shell: the shell is made of cold-rolled sheet or galvanized sheet, which has good atmospheric corrosion resistance performance. The shape of air inlet is designed in conformity to aerodynamics. Air is easy to go into the impeller. Air inlet's size is the same air outlet's. It's easy for installation. The inlet cover connects with outlet cover by bolt which is easy for repairing and cleaning.
(2) Impeller: fans in the mode of GDF100A, GDF125A, GDF150A, and GDF160A adopt new plastic impeller with the diameter of 190mm: fans in the mode of GDF200A and GDF250A adopt new plastic impeller and metal impeller with the diameter of 250mm; fans in the mode of GDF315A adopt new metal impeller with the diameter of 280mm.All the impellers are designed as backward impellers. Under the normal operation, the impeller can be in good cooperation with shell, and it have the characteristic of big amount of wind, high efficiency and low noise. Impeller and exterior rotor motor are integral, helping to cool down drive motor and prolong fan's life.
(3) Motor: the GDF fans take single phase asynchronous motor. The impeller of the motor can connect directly with shell and the impeller i driven by the rotation of shell. The motor integrates with wind wheel. The motor has a rational construction and small volume so that saves the installation space. Also, the motor has the feature of a light weight, smooth running, high efficiency and a long operating life.
(4) Wiring box: the wiring box is made of ABS fire material of withstand high temperatures. The wiring box has a good fireproof performance and it is easy to install outside the fan. Also, it is very convenient to dismount.
