Characteristics
Low-noise, low power consumption, superiorly made, newly designed structure and type-variety.

Application
Widely applied in various air-conditioners and air-handlers. Besides, in places of ventilation

Structure type
DF series Fan structure can be divided into two types: motor built-in and built-out. The Fan mainly consists of impeller housing the inlet of wind transmission system motor , etc
Impeller
Made by welding or riveting pieces of forward -carved Sheet metal blades and the wheel plate together. And the wheel plate is in the middle of the impeller or at the side .Its materials are high-quality Aluminum alloy or steel plate. Static and dynamic balanced to assure excellent pneumatic performance. High-efficiency; Low-noise; Little starting-inertia and week-vibration.
Housing
Whole-structured by wedding steel-plate together; Easy to install and repair.
The inlet of wind
Single or dual inlet lying at one or both sides of the fan . Streamline with the section of the axial plane to assure the air flow can be through to the impeller homogeneously.
Little lost; High efficiency; Low-noise .
Motor
l Built-in type use YW external-rotor low-noise motor
l Built-out type use Y series motor. Each fan can be sorted into left or right rotor-type .In the view of motor side, if the impeller rotates in clockwise ,the fan is called as right-rotating fan .If in counter-clockwise, called as left-rotating fan.
l The discharge direction of the centrifugal Fan is demonstrated by the angle of the housing. The Fan whose motor is built-out and directly driven is made into sole type when delivered to you; Could be reinstalled in accordance with your requirement .No need to note when playing your orders. The Fan whose motor are built-in have three type according to discharge direction such as O??90? ?180?. Be able to be adjusted freely.
