Axial Fan function
You know the radiator in a car? it's an Axial Fan. Semeru Inti Sukses presents axial fans that can be applied to many industries, our Axial Fans use generators, air compressors, diesel engines, and almost any type of directional cooling you can imagine. However we design and sell Axial Fans for other applications that have nothing to do with cooling as well. Our Axial Fans are currently used in snow-making machines and hovercrafts.
How Does an Axial Fan Work?
The axial fan works on the same principle as how the wings of an airplane generate lift. The wings of an aircraft have an aerofoil shape that propels the air forward diverted above and below the wing. The air above the wings travels farther than the air under the wings which results in a difference in airspeed above and below the wings. The higher velocity airflow over the wing has a higher dynamic force resulting in a lower static pressure. Under the wing, air moves more slowly which means it has lower dynamic force and higher static pressure. A higher pressure difference under the wing and a lower pressure above it produces lift.
In the case of the Axial Fan, we use the impeller blade like an aerofoil, but instead of generating lift we keep the fan blades rotating in a stable axis and this creates airflow. It follows Newton's third law of motion that for every action there is an equal and opposite reaction. The air above the aerofoil is drawn into the fan by reduced static pressure and pushed out through the fan creating an area of positive pressure.
To direct airflow and get optimal performance, we use a mounting plate with a bell-shaped inlet cone to create smooth laminar flow to the suction side of the fan. The fan is held centrally on the mounting plate by a mounting guard which maintains a small tip distance between the fan and the bell mouth.
There are other methods of mounting an Axial Fan including placing it in a plain diaphragm hole or within a short radius, but this method of installation compromises performance. Using a full bell mounting plate will ensure that the optimal performance of the fan is achieved.
