“Bifurcated Axial Smoke Exhaust Fan “
A direct drive bifurcated axial smoke exhaust fan is a type of fan used to remove smoke and other fumes from buildings, such as in the case of a fire.
It operates by using an axial impeller, a fan that moves air parallel to the axis of rotation.
The direct drive feature of this fan means that the electric motor is directly connected to the impellers without needing a belt and pulley system.
This eliminates the potential for the maintenance and belt replacement required with belt-driven fans.
The direct drive also provides a more efficient transfer of power and can also provide a means of adjusting the speed of the impellers.
The natural drive feature also helps to isolate the motor from the impellers, reducing the amount of vibration and noise produced by the fan.
The fan is typically mounted on the roof or the side of the building and is designed to remove smoke and other fumes from the building through a series of ducts or pipes.
This can help to prevent the spread of smoke and other harmful fumes throughout the building, which can improve the safety of the occupants and help to protect the building from damage.
The bifurcated design of the fan is ideal for buildings with complex layouts or multiple levels, as it can ensure that smoke and fumes are removed from all areas of the building.
It is an essential component in fire protection systems, which can help to ensure the safety of building occupants and protect the building from damage in the event of a fire.
