Shopping is one of my favorite things to do but by far one of the most expensive and most hectic of my hobbies. There are always so many things that you need to consider when you are out on a shopping spree.
The same is the thing when you have to upgrade your house; with the outdoor ceiling fans in this case.
There are some basic things that need to be considered, so let us move on straight to them.
The blade pitch of a fan is the angle that its blade has from the air. A higher angle or a more excellent blade pitch means that the fan will be able to make more significant movement through the air as it sweeps across.
However, this angle should not be too steep that it takes away the look and the working power at the same time.
Furthermore, a greater angle of the blade will ask for greater strength and, thus, a better motor for the seamless working of the fan.
Rounds Per Minute (RPM)
Rounds per minute are the number of times the fan rotates in a single minute. This is very obvious that a higher RPM will mean that the fan rotates more and thus generates cooler air.
However, as a matter of fact, fans do not make the air cool by themselves. Instead, they circulate the cool air around and make it feel cooler without changing the temperature of the room.
Their RPM is also associated with their ability to circulate the air around; this factor is measured as cubic feet per minute, or more simply as CFM. The higher the CFM of a fan, the better it is in generating a cooler air and more reach it has.
Good fans will produce a CFM ranging from 6000 to 9000.
Blade Shape and Size
This is something that is actually quite easy to understand when compared to the previous technical concepts. The larger the blade is, the more it will be in contact with the air and thus produce a stronger air current.
However, this is not limited to this, and neither is this much simple. Firstly, a larger blade will mean that it is heavier than the others and therefore needs much more strength; thus, a stronger motor.
Secondly, the lengths of the blades are only effective to a certain limit. Once that limit has been crossed, the fans will start losing their efficiency even though with the most potent motor around.
When it comes to shape, the shape also plays a crucial role in generating airflow. Fans are technically engineered to produce the maximum airflow with minimal resistance. If the resistance they get from the air is a bit too much, they will lose their strength again.
Therefore, always make sure that the fan you want to buy has the right shape and blade size.
