What is a ceiling fan and where to use it?

The ceiling fan is an ideal appliance for ventilating, cooling and air-conditioning rooms. This model of fan is one of the best options available because it has triple function: ventilate, circulate the air and illuminate, since these devices have device to fit lamps. It is a fixed installation model, so it will not be possible to change the environment. You need to choose a certain place in the house and lead the electric wiring to this point on the wall, so the installation should be done by a professional.

If you already have the point for the ceiling fan, some models are easy to install, just fit the piece, turn and lock. But, if it's the first time you're going to put this type of fan in your house, it's better to look for a technician.

If you choose a ceiling model, remember that the air flow rate per second has to be equivalent to 10% of the room's size, that is, for every 20 m², consider a fan with a flow rate of up to 2 m³ per second. For larger and more spacious rooms, it is advisable to purchase more than one device.

What are the advantages and disadvantages of the ceiling fan?

One of them is the exhaust function. Many people, however, are in doubt about what it does: basically it is to distribute the wind throughout the room, while the fan function takes the wind only downwards in a single air stream. The temperature brought by the fan is different from the extractor fan. While the first directs the cooler air downward, the exhaust fan throws it upward, causing it to mix with the warm air that is on the ceiling, leaving the room with a uniform temperature. The exhaust fan can be used to air-condition the room in winter. But if you are going to change the option exhaust fan to fan and vice versa, wait for the device to stop spinning completely, not to damage the fan and, consequently, reduce the durability of the piece.

Another important information is that the number of propeller blades, the motor power, the number of revolutions per minute (RPM), weight and shape of the piece (some blades are inclined to generate a stronger air current) are aspects that directly influence the efficiency of the fan. The actuation of this device can be done by wall control, pull cord, remote control and even by mobile phone app, if your fan has Bluetooth connection. Because of its size, this type of fan does not fit in corridors and narrow rooms, but it is ideal for small, medium and large environments. You can also put this device in your room, most models emit low noise and some even have night function, which makes the device even quieter and slower rotation. Last but not least, the fan design is also an important factor in choosing a model, since these objects are also decorative. Some have a clean, discreet and monochromatic design, others are larger, with a metallic finish or in wood tones, and there are models similar to chandeliers, with several lamps. And if you choose a model of ceiling fan that illuminates, know that some have compartments for lamps that must be purchased separately, while other models have integrated LED lights. We have prepared a table with the main advantages and disadvantages of the ceiling fan, check below:

Advantages

  • Ideal for small, medium and large environments, ventilates from 16 to over 28 m²
  • Low energy consumption
  • Can be used on hot and cold days
Disadvantages

  • Manufacturing material: may be made of plastic, metal, wood or MDF;
  • Operation of the device: by string system, wall control, remote control or even by smartphone;
  • Area covered: ranging from 16 to over 28 m².

There are other models of fans, besides the ceiling fans, they are: the portable models, ventilation tower, air circulator and the wall fan. The wall fan is a hybrid of the ceiling and table models, and is ideal for small and medium environments. However, it is also efficient in environments such as churches, restaurants, factories and other spaces, because it has an oscillation function that takes the wind from left to right uninterruptedly. The wall fan is very similar to the ceiling model. To explain the similarities and differences we have prepared a table comparing the main features of these products so you know what changes from one model to another, check it out:

The portable, table or column fans are the most common models, can be transported to different environments and are ideal for domestic spaces. The ventilation tower is a more modern device and has different functions from other fan models, such as air purifier and timer function to set the time to turn the device on and off. Another type of fan is the air circulator. This model has a bifurcated wind flow, which directs the air to two directions and circulates it all the time through the room, eliminating the feeling of stuffy place.

What cleaning and maintenance care should I take with my ceiling fan?

The function of the ceiling fan is to circulate air to cool the environment, so it is necessary to pay close attention to the cleaning of this device, because if it has dirty propeller blades, this dirt will be carried to the whole environment, causing discomfort and allergic crises.

When clean, the fan becomes an ally in the care of respiratory health since it is proven that the ambient air needs to be changed to prevent the proliferation of viruses and bacteria that cause diseases.

The cleaning must be done with the electric power off and you can use a cloth dampened in water with a little neutral detergent to clean the plastic parts such as the propeller blades. If the appliance is very dusty, you can use a portable hoover to facilitate the removal of dirt, especially from the motor. The bearings of the fan motor should also be looked after. To keep them running smoothly and to extend the life of the appliance, lubricate these parts with oil, silicone or grease for mechanical parts. Ceiling fans wear out over time and therefore require maintenance. With some preventive care, cleaning and changing the oil you can already avoid damage to the device. Every 6 months check that all screws are tight and balance the piece to see how it reacts to shaking. When the device does not receive proper maintenance it can have loose parts and present difficulties to rotate or even emit stronger noises. In such cases, unplug the device and see if you can understand what problem is occurring, if you do not reach any conclusion ask for professional help. A fan with a problem can cause electrical accidents.

Buying Criteria: Factors When Buying Ceiling Fan Models

Although you have learned a lot about ceiling fans so far, it is important that we go on to clarify a few more details. This way, you will be 100% satisfied with your purchase. Consider the following factors:

  • Performance
  • Noise
  • Resistance
  • Safety
  • Procel and savings label
  • Installation mode
  • Lighting factor
  • Decoration

Below, we will explore each of them.

Performance

Some factors influence the performance of the ceiling fan, such as the number of propeller blades, the number of revolutions per minute (RPM), motor power and blade shape. Nowadays, there are models that have from 2 to 6 blades on the propellers, and the higher the number, the more capacity to spread the wind. But there are right models for every room size: the 2-bladed models are ideal for spaces up to 20 m², the 3-bladed models are suitable for rooms larger than that, and the 4 to 6-bladed models are more decorative. And there are different models of fans for each size of area, from fans that ventilate small spaces up to 16 m², models that ventilate medium-sized spaces between 16 and 28 m² to large fans that ventilate spaces of more than 28 m². Another important detail is that the ceiling fan must have an air flow rate ratio per second equivalent to 10% of the room size, i.e. for every 20 m², consider a fan with a flow rate of up to 2 m³ per second.

Noise

If you are thinking of buying a fan to install on the ceiling of your room it is essential to take into consideration the level of noise that this device emits, as noisy fans are annoying and can disturb you at rest time. Almost all models are very quiet and some have function that further reduces the noise of the device during the night, so check if the model you want to buy has this feature.

Resistance

The manufacturing material of the fan is an essential factor for the strength of your device. The blades should be made from good quality materials, such as some types of harder plastic, metals, wood and varnished MDF. If the place where you live is more humid, such as the coast or mountainous regions, prefer to buy a plastic fan, as it does not absorb humidity. But if you live in urban environments, feel free to choose the material of your fan.

Safety

Ceiling fans are safer than other models because the wiring is inside the wall. On the other hand, they may fall from the ceiling if they are not well installed, so hire professional help to install the fan.

Procel Seal and savings

The Procel seal indicates the energy efficiency of the fan. Give preference to devices in categories A or B, because the fans in categories C and D can spend 2 to 4 times more energy and this counts a lot on your electricity bill, especially if you consider that on hot days the fans are usually on all day. But, know that in general, most models on sale are quite economical, especially when we take into account that a ceiling fan at high speed uses only 2% of the energy used by an air conditioner in the same period of time.

How to install

To enjoy your ceiling fan, it is important to install it in the right position and place. The wall needs to support at least 25 kg and your fan should be installed together with the fixed wiring and using at least 5 wires to connect the power switch with the electrical part of the appliance.

To avoid accidents with the fan propeller, the device should be installed at least 2.30 meters away from the floor and in the centre of the room, because the recommended distance between the propeller and the walls is at least 50 centimeters. There should also be a distance of at least 20 centimetres between the propeller blades and the ceiling. Due to the risk of accidents caused by incorrect installation and the complexity of the procedure, we recommend that you hire a professional to install your ceiling fan.

Lighting factor

Besides leaving the house ventilated and fresh, the ceiling fans serve to illuminate the environment, since most models, if not all, already come with compartments to fit light bulbs. These lamps can be placed in external receptacles, in internal compartments and embedded or even fitted inside a frosted glass globe that softens the intensity of the light. There are also models that already come with LED lights inside, dispensing with the purchase and use of light bulbs.

Decoration

The ceiling fan is one of the pieces that make up the decoration of the living room, bedroom or office. That is why there is a diversity of models with infinite design styles to please the most varied consumers. There are monochrome and discreet pieces made of shiny plastic, larger models with details in different materials and textures, with steel base and blades of copper metal propeller, glass pieces crystal style, with wood finish or similar effect.

The arrangement of the ceiling fan fixture also makes all the difference, there are models in which the lamp is embedded, in others she is in receptacles inside metal arrangements that resemble flowers and the most modern models have LED lights embedded, giving a futuristic look the piece. The multiplicity of styles and models allows you to buy pieces with different designs to match certain rooms of the house, such as a modern living room with a fan of LED lights, and a more classic model for the entrance hall of the house or the master suite.
