Components of a Ceiling Fan

Ceilings fans circulate air inside a room. Usually, they are electrically-powered mechanical fans that are suspended from ceilings. In Singapore, ceiling fans are also used to cool, or warm, the room. As a highly developed economy with a well-established service sector, ceiling fans can be found in large conference halls, restaurants, and office complex; as well as residential homes and apartments.

Singapore has a tropical climate, and the authorities are advocating a greening policy which means that ceiling fans must be environmentally-friendly in terms of design and operation. This means that ceiling fans must be built of non-toxic materials, and in case they are irreparably damaged, their design allows some of the parts to be recycled while the non-recyclable parts can be properly disposed off. Also, the material used to build the non-recyclable parts should at least be biodegradable, so as to minimize the load of waste product associated with damaged ceiling fans.

Energy Efficiency

A good ceiling fan should be energy-efficient, which means that it does not waste energy. The design of quality ceiling fans allow them to adequately circulate air inside rooms while rotating at a slow speed. Some ceiling fans feature blade designs which have been purposely built for better aerodynamics, and this ensures that when the fan is rotating, less energy is used to overcome air resistance.

Power consumption can also be reduced if home owners, or fan users, turn on ceiling fans only when they are inside the house or building. However, if the ceiling fans are installed in bakeries or kitchens where ovens are continually being used, then the fans can be left running even if there is no one at home.

The interior design of the home also determines the amount of power consumed by the ceiling fan as it dictates the size of the room in which air can circulate. For this reason, an eco-freindly interior design improves the degree of energy efficiency of installed ceiling fans, as well as improving the air quality. Therefore, if you are planning for a home renovation, you should consider using an eco-freindly interior design to renovate and refurbish your home.

Components of a Ceiling Fan

There are different types of ceiling fans available in the market in Singapore. Nonetheless, all these ceiling fans have the following basic parts, which are described alongside their functions.

- Ceiling Mount: This is the mechanism used to mount, or install, the ceiling fan into the ceiling (or roof). They also provide conduit for electric cables to supply power to the electric motor of the fan. There are 3 main designs of ceiling mounts:

1. Ball and Socket: A metal or plastic hemisphere housing a metal bracket is fitted on the ceiling, and it secures the downrod to the ceiling.

2. Claw hook system; It is also called the J-hook system, and it features a metal hook that has been fitted into the ceiling, with the ceiling fan hanging on this metal hook.

3. Low ceiling adapter: This is a specially designed ceiling mount that does not need a downrod, and thus allows the ceiling fan to be installed in rooms with set roofs, or those that have low ceiling clearance.

- Downrod: It is a metal rod attached to the ceiling mount, that serves to suspend the ceiling fan in the room. They are different sizes of downrods, with the fan type and room size determining the length and widths of the downrod to be used. Downroads are not used in areas with low ceiling clearance.

- Motor housing: This is an encasement, usually decorated, that houses the electric motor of the ceiling fan. Usually, each ceiling fan manufacturers creates a unique design of the motor housing. Also, due to its size and prominence, they can be used to distinguish different types of ceiling fans that have been made by different manufacturers.

- Switch housing: This is a metal cylinder that is mounted below the electric motor. It houses various electrical components including capacitors, switches, and electric wires; and in fans that require lubrication, it houses the oil reservoir. It also protects these parts from damage. It is also called the nose column or switch cup.

- Electric motor: Ceiling fans are usually driven using single-phase induction motors, with most motors having 18 poles. However, there can be 18, 20, or 22 poles. The windings of the poles ensure that the motor has a low operating speed. Even so, motors have stator voltage controls which allow for a wide range of speed control.

- Flywheel: It is attached to the shaft of the electric motor. Blade irons are usually attached to it using bolt. Lock screws are used to lock the inner ring of the flywheels onto the motor shaft.

- Blades: These are the paddles that move the air around the rooms. They are also called wings, and they are built in different designs. The axial fan design maximizes the pressure of air being circulated. It is usually made from plastic, wood, iron, plywood, or aluminum. Generally, quality ceiling fans have well-designed blades which are built from rust-resistant, non-corrosive materials.

- Blade irons: They hold the blades in place, and also attach them to the electric motor, or the flywheel. They are also called flanges, blade brackets, blade holders, or blade arms. Some ceiling fans do not have blade irons, but instead have rotors.

- Rotors: They are usually one-piece die cast devices attached to the motor, which receive and secure blades. Unlike blade irons, rotors are quite stable and eliminate balance problems, as well as minimize the extent of exposed fasteners.

- Blade badges: These are visible decorative adornments that are fitted to the underside of blades so as to conceal the screws which attach the blades to their blade irons. There are also assorted switches which are used to turn on and off the ceiling fan; as well as adjusting the rotating speed or the direction of air draft.

- Lamps: They can be uplights, downlights or decorative lights. Uplights are used to create ambiance while downlights are a light kit used to improve the ambient light in the room.

Positioning and Air Draft

Ceiling fans are usually suspended from the center of the ceiling as this allows them to circulate the maximum amount of air possible. Another important aspect of the ceiling fan is the direction of blade rotation as this determines the direction of the air draft.

There is air stratification in a normal room with warm air settling at the upper part while colder air settles at the lowest part of the room. Therefore, if you need to warm the room, you need to ceiling fan to create a downward draft which brings warm air to the lower part of the roof while colder air is pushed to the roof of the room. If you need to cool the room, then you set the ceiling fan to create an upward draft of air.

Tips To Consider When Installing Ceiling Fan

Ceiling fans were constantly undergoing changes and improvements, such as adapting a motor that was originally engineered by Philip Diehl for use in sewing machines. The Diehl Electric Fan actually operated much like the common modern day ceiling fans, with each having its own motor that eliminated the need for the belt systems that were both bulky and costly.

Fortunately, ceiling fans have continued to evolve throughout the years. Because of this, many different makes and models are now available. They run the gamut from strictly functional or whimsical, to a fashionable accessory, both simple and complex in design.

6 Useful Tips For Balcony Ceiling Fan Installation

A balcony ceiling fan is one of those things that are not only very beautiful but also rather practical and functional. Unlike the desk fans that are considerably dangerous especially if you have young ones and pets around the house, the ceiling fan is safe and completely out of the way. Also, they come in handy both during summer and winter making them useful all year round in Singapore. These are just some of the reasons as to why you should have a ceiling fan. Like any other part of your house, the balcony is a relaxing place and you should be able to sit there comfortably. This is why balcony-ceiling fans require a special consideration when you are looking into the concept of ceiling fans for your home. 

Below are six useful tips that will take you through the exercise of choosing and installing a proper balcony-ceiling fan. 

-Mind the fan’s size
-Seek the best in quality
-Check its rating depending on whether your balcony is open or not.
-Consider designs and the theme of your home
-Ceiling height and energy ratings are very useful information
-Consult with a professional

Six useful tips for balcony ceiling fan installation

1. Size
The first thing to look at when you are looking to install a balcony ceiling fan is the size of the balcony with respect to the fan that you would like to buy. If your balcony is relatively small, you may want to buy a fan that is also small and will not look overwhelming on the area. Look at your balcony and visualize the fan on the ceiling. If it looks bigger than the room than you probably should not buy it. Rather find something that will look like a perfect fit, which is neither too big nor too small. 

2. Quality
Like most of the items you would buy in your home, the ceiling fan should be able to last. This means that you have to look for a fan that is not only affordable but also of the highest quality possible. The balcony is usually an outdoor area, meaning that there is exposure to the environmental elements like sunshine and wind and most cheap products would deteriorate easily under such harsh conditions. Also, seeing as the ceiling fans are useful both during winter and during summer you may have to keep it on a lot. Having the best quality will ensure that it is durable and will serve your home for a considerably long time. Like in many other instances, cheap is expensive here since a cheap fan will only have you replacing or repairing it more often than a high quality one.  

3. Wet rated or Damp rated? 
When installing a balcony ceiling fan, you need to ask yourself whether you need a wet rated one or a damp rated one. The wet rated ceiling fans are especially practical for open balconies where they have exposure to rain, snow and wind. This means that they can survive the harsh weather conditions of the outdoors. If your balcony is not open however, you can settle for the damp-rated ceiling fans that are rather sensitive to the harsh elements. Depending on where you live and what your balcony looks like, you should be able to choose the appropriately rated fan for your balcony.  

4. Designs and theme
The balcony is a part of your home and as such must be part of the concerns that you consider in your home theme. This means that the balcony ceiling fans have to be a part of your home décor theme by either being of a similar or related color, material or historical era, or even design. If your home has a Victorian theme, it would be only natural for you to install a Victorian ceiling fan in your balcony and if the theme is mostly African you can also just as easily find a balcony ceiling fan that has an African theme. The main factor here is to avoid having a ceiling fan that looks out of place in your home. There must be some coordination with the rest of the décor unless you are aiming for an uncoordinated look as your theme.  

5. Height and energy consumption
The height of your house, and in this case your balcony, affects the kind of ceiling fan that you can install. This is because you would not want to install a ceiling fan that is too low and can thus be dangerous or too high to be effective. There are ceiling fans for both low and high ceilings and you have to pick one that matches the ceiling height in your balcony. On the idea of energy consumption, everyone today shares the concern of conserving energy and thus a fan with a lower energy consumption is considerably better seeing as you will save energy and cut down your power bills. Considering that these fans could be on all through summer and winter, it will be best if you buy one with an excellent star rating for affordable power consumption.  

6. Professionals
Decorating the home is like designing a relaxing place for yourself. It is often not only expensive but also time consuming and you could make a lot of mistakes if you do not know what to do. This is why among the six useful tips is the need to speak to a professional. You can decide on the type of fan you want for your balcony in terms of the theme, size, color and even energy rating. However, you will need an expert to guide you with things like the type of material that would be best for your home depending on the theme and the kind of lighting that would go well with the design that you want among other things. Buying and installing the balcony ceiling fan is rather simple if you have the guidance of a professional in home décor and especially with the ceiling fans. You will appreciate that like in any other field, these professionals are often willing to provide information in the future in case you have a problem with your ceiling fan.

Talking about the size of your fan and room proportion it can vary depending on the size of your room. If you have room that is smaller than 12 feet in any one direction, then a fan with 36 inch wide bladed would be good enough. If the maximum distance between two walls is 12 to 15 feet, then you should buy a fan that is 40 to 48 inches wide. That will help you get enough air flow till the corner of the room.

Similarity if you have walls that are longer than 15 feet in distance, then you should use a fan that has 52 inches wide fan blades. If you will take any smaller fan, then you may not experience cooling at every corner of the room and you investment and hard work will go into vein.

Controls: When you buy a ceiling fan, then make sure you get one that can be controlled from the switch or a knob. If you will have a ceiling fan, then it not controllable, then it will run only the full speed and if you are feeling colder, then you cannot reduce the fan speed.

Whether you are buying ceiling fans in Singapore for the first time or replacing your existing fans to give new look to the interior of your home the steps provided here under will be extremely helpful to you in buying the best and stylish fans for your home or commercial establishment.

Budget: The first thing to focus on while buying stylish ceiling fans in Singapore is your budget in this regard. You can find stylish fans in various price ranges from $50 to $1000 and above depending upon their features, quality and performance. You can prefer to choose these fans within your budget from online stores as they usually offer various discounts and promotional offers to their customers to improve their traffic.

Location: The second thing to be considered is the location where you want to install the ceiling fan as it can your living room or porch. It will help you in considering the fans according to their performance as each location is exposed to different weather conditions. If the fan you selected is specified for certain locations then it will be easier for you to take final decision. You can see if any rating is mentioned on it as some fans are rated UL Dry, UL Damp or UL wet assigned by Underwriters Laboratories. Usually fans with wooden blades are rated with UL Dry rating as they are specially designed for moisture and humidity free dry interior locations. Fans with UL Damp rating are considered the best for moist and humid locations without any direct contact with water. UL Wet rating helps in selecting a fan to perform in any weather condition including snow, rain, ocean water or spray. The motor and blades of these fans are made of moisture resistant materials to perform all weather conditions.

Size: It is another important factor to be considered while choosing stylish fan for your room. The size of fan should be chosen according to the size of the room you are going to install it in. The ceiling fan of any size cannot suit to any location as smaller fan cannot provide adequate cooling to larger room. Fans are usually available from 14 – 72 inches in size from which you can choose according to the area of your room and the height of its ceiling. One important thing to be considered at this stage is that the blades of the fan should be at least 7 feet away from the floor. If the height of the room is less than 7 feet then instead of using standard down rod for mounting it you can flush mount or slope mount it.

Light: Some of the stylish ceiling fans today are provided with lighting to give a unique look not only to the fan but to the entire environment of the room. If you want to install it in a space where enough natural light is not available and additional lighting fixtures are required then you can prefer for fans with lighting arrangements.

Energy star is another feature that can help you in selecting the best fan for your home as they help in knowing their energy efficiency and durability. fans with high airflow are also considered the best as they provide more air circulation in the room by consuming lesser energy than others.

Control: Various types of controls are provided these days with ceiling fans to enhance their style and ease to operate. Some of them have pull chain control whereas others have wall control as well as remote control so that they can be controlled without accessing them manually.

Ceiling Fan VS Standing Fan

A basic difference between Ceiling Fan VS Standing Fan

With the help of a fan, you can feel cool with the help of air flow and you can feel comfortable as well. But sometime people stay in dilemma and they do not know if they should chose a ceiling fan or they should buy a standing fan for their home. Well, I would say ceiling fan and standing fan both have some pros and cons in it and here I am sharing few details about same that can help you take your decision in a wise manner. 

Positioning: As name explains it all a ceiling fan always remains there at the ceiling and a standing fan remain standing on the floor. This difference of positing allows you to have different kind of air flow as well. With ceiling fan you get the flow from top to bottom and it gives you feeling of cooling. At the other hand a table fan stands in front of you and it flow the air in the horizontal direction. The biggest difference of its positing is that you can change the position of a standing fan as per your choice, or requirement. But if we talk about ceiling fan it always remain fixed a place and you cannot easily change its position once it is fixed.

Electricity efficiency: In Singapore almost everyone can have an air-conditioning system as it is one of the most essential instruments to get the cooling. But an AC consumes a lot of electricity and that is why people use fan along with air conditioning system so they can reduce their electricity bill. If you are using a ceiling fan then you can set the temperature of your AC up to 4 degree higher and then also you will get equal amount of cooling and comfort. That means you can save electricity using ceiling fan along with your AC. However, you will never have that kind of comfort and electric saving both with a table fan. Also, if we ignore the Air conditioning part then also, table fan consumes more energy compared to its ceiling counterpart. 

Coverage area: If you choose right kind of ceiling fan and if you install it properly, then its airflow can cover the entire room as well. But if we talk about the table fan then you will not have that liberty and you will not be able to cover the entire room with it. However a standing fan can give more flow to you with fast air flow. So, if you want fast flow of the air from a close distance, then you can use a table fan for that else ceiling fan would be a good solution for you because that can cover bigger area from a single place. So, that will be another good thing that you can do with this particular

Safety details:
When we use a fan then most of the people will raise question about its security. If a ceiling fan is installed properly and it is installed at a safe distance the you don’t have to worry about the safety part at all. A properly installed ceiling fan will never fall down on you and nor it will give you any other complication. However, if it is not installed in a proper manner and if it is installed at a place that is in your reach then it will not be safe for you. We can say the same thing for standing fan as well that if you get proper stand and if you keep at a safe distance from your then it will be safe for you. But if it is at a close distance from you or it is not covered properly then you might get injured with it. So, we can say both the options will have similar concern for safety part.

Look and style: as far as style part is concerned, you can get various styles by both the options. Since, you can have so many options in standing fan as well as in ceiling fan so you will be able to get good looks in your room with both the options. However, if you are planning to use a fan for interior decoration then you will not be able to get the best outcome with standing fan as its position will keep changing as per needs. At the other hand, a ceiling fan will help you get better output with this requirement in easy manner. You can get some special kind of ceiling fan with lights or special design and you can choose a nice option that will help you in this requirement. So, you can choose an option according and you can get the best output with it in a wise manner.


Cost difference:
These days you cannot give a fixed statement about the cost of any fan. But as a thumb rule the cost of a ceiling fan is always higher compared to standing fan. In most of the cases a ceiling fan will cost you double amount compared to a standing fan. Also, if you want to use a ceiling fan then you need to get some help from experts that can install and configure the ceiling fan for you in proper manner. At the other hand, you have no reason to worry about the installation parts because a standing fan is easy to use and you do not need any extra efforts for its. So, we can say cost wise standing fan wins the race compared to ceiling fan.

Also, if we talk about the related complications or troubles, then both the options can have some complications in it. With improper installation a ceiling fan can wobble and it can make weird sound while working. Similarly, if covering of a standing fan is not in proper shape or if you do not close it properly then you might end up having bad sounds from it. So, when you choose either of these options make sure you keep all the things in your mind and take your decision wisely.
