Outdoor fans help to keep us cool in exterior areas such as pool, verandah, patio and pergola etc. These days, there’s a wide range of shapes, colors, sizes, styles in which outdoor fans are available. Hence, it becomes difficult for an individual to decide as to which type of outdoor fan he/she should choose. This guide will give you a gist of key things that you should keep in mind while installing an outdoor fan.
Size of the Outdoor Fan
The size of the outdoor fan depends upon the size of its blades. Fan blades play a crucial role in determining the amount of cooling. Apart from blade size, blade’s angle, speed of rotation, shape and number also determines fan’s cooling capacity. Good quality fan blades can maximize the cooling ability and air flow of the fan.
Size of outdoor fans is dependent upon the blade size. The wider and longer the size of blade is, more will be the amount of air generated. However, choice of an outdoor fan largely depends upon the size of area which you want to cool.
Is A Larger Outdoor Fan Better Than a Smaller One?
People generally have perception that large outdoor fans provide more cooling in comparison to small ones. However, this perception is not entirely true. This is because more number of smaller fans will provide air flow in more areas in comparison to one large fan.
Moreover, smaller outdoor fans provide you ease of concentrating the air flow in areas where you need it. Hence, taking multiple outdoor fans is better than one large fan. Make sure that when you buy an outdoor fan, its blade size has a gap of minimum 24″ / 60 cm. This much gap will ensure that air movement of one fan doesn’t interfere with air flow of the other one. Large outdoor fans usually move more airflow in comparison to small fans.
Using A Combination of Different Fan Sizes
You can use a combination of various outdoor fans to keep your exterior cool. For instance, you can place one small ceiling fan to cool the middle area and table or standing fan can be placed at the corners. The number of fans which you need to place in exterior largely depends upon the amount of air movement you require. As the exterior doesn’t have any ceilings or walls, you need to place a free-standing fan like a floor fan, table or pedestal fan to cool the entire area.
Required Air Flow
There is a wide range of outdoor fans among which some are more powerful than the others. Some fans are designed to create more air movement while others give a gentle breeze. The factors which determine power of an outdoor fan include shape and pitch of the blade, material, revolutions per minute (RPM) etc. One of the best ways to find how much air movement a chosen fan creates is by seeing it in action in a showroom. Otherwise sales staffs of fan stores have adequate knowledge of this and you can ask them about the air movement, which a particular fan will produce.
Rust Proof Fans
People who live near seashores seek rust-proof fans. There is a wide variety of fans available in the market from which you can choose a suitable one. Outdoor fans made up of 316 Marine Stainless Steel Grade are rust proof. In addition, fans having plastic blades and aluminum motors are also rust proof. Hence, if you live in an area near the ocean, keep these things in mind while buying an outdoor fan. You can check a great range of outdoor fans at affordable range on http://www.modernfanoutlet.com
How do Blades Affect Air Flow in Fans?
Fan blades play a crucial role in determining the amount of air flow in an outdoor fan. Wider is the blade, more will be the air flow. Moreover, material of the blade also matters a lot. Following section will brief you some facts related to fan blades.
- Material of Blade
It is important that the blade of the fan which you’re choosing for your exterior are made of warp-resistant and sturdy materials. This is crucial for durability of outdoor fans as these fans are exposed to harsher elements in comparison to indoor fans. Hence, blades of outdoor fans should be resistant to warping and corrosion.
Most of common materials which are used to make fan blades include aluminum and plastics like ABS. Some heavy-duty fans have fiberglass incorporated in their polypropylene/ plastic blades. Blade fans made of materials like woods and rattan won’t have much durability due to outdoor use. On the contrary, plastics and aluminum are safer choices as they are more durable and can easily survive harsh exterior conditions.
- Rotations of Fan Blade
Faster is the blade rotation, more will be the airflow which in turn provides more cooling. Blade rotation is also known as “fan speed”. It is the number of times that a blade completes its rotation in one minute. It is measured in revolutions per minute (RPM). Rotations of fan blades are an important contributor to airflow and hence should be kept in mind while buying fans. You can take advice from salesperson on this while buying an outdoor fan.
- Tilt and Pitch of Fan Blade
Pitch of the fan blade is also important in determining airflow. Generally, more is the pitch, higher will be the airflow. However, pitch size affects the size of fan motor. This means, if the pitch of the blade is high, power of the motor will increase. Usually, pitch of the blade ranges from 9 to 15 degrees.
More tilt in the fan’s blades distributes the air more evenly. This means that a fan having more tilted blades will give you less airflow directly and more airflow on outer parts. Hence, make sure that you determine the amount of airflow that you require in your exteriors and choose the fan’s pitch and tilt accordingly.
Hope this guide will help you to understand how to choose an outdoor fan as per your requirement. You can visit any store to have any idea of various types of outdoor fans available in the market.
