LTBH series backward double air inlet belt driven centrifugal fan adopts a backward impeller with belt driven. The motor is located outside the volute and drives the fan impeller to rotate by the way of belt driven. The proper transmission ratio can make the rated working point of the fan match the required working condition well, improve the overall efficiency of the unit, and achieve the purpose of energy saving and environmental protection.

Our fans are suitable for supporting various air conditioning, purification, air handling unit, HVAC and other products, and has been widely used in hotels, schools, hospitals, factories, mines, cinemas and other fields.
This series use the belt drive mode which can have configuration of rated flow and pressure freely.
Model Definition
Such as LTBH630 is centrifugal air conditioning fan, back curved blade, blade diameter 630mm.
The motor installation position of this series of fans can be redesigned according to your requirements, which can be placed above, below or on the side of the fan to adapt to the space limitation of your installation site.
( facing the fan pulley, the clockwise direction of impeller rotation is called CW, and the counter-clockwise direction of impeller rotation is called CCW. )
*** The default rotation direction of our centrifugal fans is CW. If users want different rotation directions, must point out clearly at the time of ordering. ***
Power supplies three-phase voltage and frequency customized;
