In fact, the name Oberlander 2 Blade Ceiling Fan might sound unfamiliar to the public. However, if you are the interior designer or you like electronic equipment, you may have heard of this fan. Unlike the modern ceiling fans that we know today, these ceiling fans have unique shapes. Yes, this device has two small orbit fans with many blades. In the theory, this is certainly good as it can increase the airflow in the room. With the increased airflow, your body temperature will drop faster because of the faster sweat evaporation process.
For your information, this ceiling fan is quite rare to use, especially in the modern style buildings like in urban areas. Moreover, the Oberlander 2 Blade Ceiling Fan does not need too much electricity since the driving motor is not too big. This is also influenced by the fan blade size itself. The bigger (longer or wider) the blade, and with the drag (the force opposite to the direction of motion of the object), this will slow down, reduce airflow and increase the fan power consumption because the motor is working harder and cause a higher sound that may disturb you. Having a smaller blade or amount can reduce the drag but that will cause the resulting airflow to decrease.
In addition to the fan with many blades, it turns out there is also fan with one blade. This one blade ceiling fan is quite rare in ordinary homes since the price is much more expensive than ordinary one. In this case, it feels normal because this fan besides being used as furniture, it can also be used as unique decoration. The fan comes with modern design and has more sophisticated technology. Some ceiling fans have an aerofoil profile as well to produce high airflow for cooling the room and your body with low turbulence without disturbing noise. It is such a big deal, right?
When compared to the many blades fan, the fan with one blade certainly has more advantages. However, you surely do not need to be discouraged. With an ordinary fan as long as it has good quality, the wind rotation produced is no less strong. Besides, in terms of ceiling fan designs that are quite rare and seem antique, having two smaller fans with different sensation of wind makes Oberlander 2 Blade Ceiling Fan also no less attractive than a single blade fan.
