FAN BASICS

HOW DO I CHOOSE THE RIGHT SIZE OF FAN FOR MY ROOM?

Choosing the right size of fan does not depend only on the size of the room. It is also important to consider the layout of the room, where in the room people to tend to congregate, where the airflow is most required and how high the ceiling is.

Our smaller diameter fans (1.2m and 1.4m) produce mainly downdraft within a radius extending up to a metre beyond the blade tips. Our larger fans (1.6m and 1.8m), produce greater side-draft and less direct down-draft. Therefore, when selecting a fan, it is important to decide whether a direct cooling draft is required or whether  gentle air circulation is the more important factor.

Given below is a sizing chart that can be used as a rough guide to selecting the size fan.  Please feel free however to contact us if you would like to discuss your specific situation or room layout.

HOW DO I CALCULATE THE DOWN-ROD LENGTH?

Generally speaking, a ceiling fan should be positioned at 2500mm – 2700mm from the floor. Occasionally there may be good reasons why this cannot be done (eg; when the ceiling itself is unusually low, or where roof beam trusses prevent the fan being mounted at this height.

A quick rule of thumb is to measure the height from floor ceiling and then deduct 2700mm. The resulting figure should be the length of the down rod you will need.

The average ceiling height requires a 230mm down rod and this is what we quote as standard.

It is best to discuss this matter with your Timber Fans consultant before placing your final order.

For safety reasons fan blades should not be positioned lower than 2300mm from floor level.

HOW DO I CHOOSE THE RIGHT SPEED CONTROLLER?

We include a 4 speed wall-mounted controller with each fan ordered. If you order a fan with an LED light fitting then the Controller will include a light switch. The controller faceplate fits a standard “2 x 4 electrical box” that most houses are built with. If in any doubt, consult your electrician.

Our standard faceplates are Clipsal/Schneider in White, but other makes and colours are available on request. Additional charges may apply.

As an optional extra (for which additional charges apply) we offer a 4 speed Remote Control. This obviates the need for a wall-mounted fitting and is available with or without a light switch.

DO YOUR FANS ACTUALLY LOWER THE TEMPERATURE?

A ceiling fan does not change the actual ambient temperature of a room. What it does do, is move or distribute air. This has several interesting implications;

From a cooling perspective in Summer, by directing a downdraft onto a person, a fan creates a breeze which has a cooling effect by evaporating body moisture to make one feel cooler and more comfortable.

From a warming perspective in Winter, a fan circulates the air in a room to distribute the warm air that has risen and may be trapped in the ceiling area. By doing this, it raises the temperature of the air at the lower levels and makes one feel warmer.

CAN A FAN BE USED IN WINTER FOR ANY USEFUL PURPOSE?

Definitely.

All too often, we have energy-guzzling heaters or gas burners creating heat in a room only to find that the hot air they generate, rises and becomes trapped up at the ceiling!

By running your Fan at slow speed (no need to reverse rotation) the downdraft re-circulates the hot air trapped at the ceiling, to provide even, comfortable heat throughout the room.

A ceiling fan consumes roughly 5% of the energy of an average 1500Watt electrical heater used in the home, but can achieve heating savings of up to 30% by dispersing the hot air normally trapped in the roof space.

HOW MUCH ELECTRICITY WILL A FAN USE COMPARED TO AN AIR CONDITIONER?

You could probably run about 20 – 30 ceiling fans for the same amount of energy that would be needed to run one domestic air conditioning unit. That’s a huge difference in energy consumption!

In hot or humid environments where an air conditioner is considered essential, it makes a lot of sense to operate a ceiling fan in tandem with the air conditioner. By doing so, one can limit the operating time of the air conditioner and obtain the same cooling effect with the fan circulating the already chilled air.

HOW EASY IS A CEILING FAN TO INSTALL?

Installing a fan is not difficult but it is a precision job requiring strict compliance with our written installation instructions that come with each order.

A badly installed fan can result in fan noise or wobble and can be an electrical hazard. For this reason we strongly recommend that the installation be carried out by a qualified electrician. Failure to observe our installation instructions may result in the fan Warranty being voided.

CAN CEILING FANS BE MOUNTED ON ANGLED OR VAULTED CEILINGS?

Yes, they certainly can.

You will need to get your builder or carpenter to install a wooden “boss” or wedge in the ceiling to provide a firm horizontal surface for attaching the down rod.

Note that the down rod must be long enough to ensure that the fan blades do not touch against the slanted ceiling.

I NEED A LONG DOWN ROD. IS THAT GOING TO MAKE IT MORE LIKELY TO WOBBLE?

A long down rod does not make it more likely to wobble. In fact the increased weight of the longer rod, adds to the stability of the fan.

We can supply down rods up to 4 meters in length.

CAN I RUN YOUR FANS ON MY HOME AUTOMATION SYSTEM?

Please consult with your electrician on the specifics of your system. Our 4 speed regulators are designed to be compatible with our fan motors and we cannot guarantee compatibility when other electrical systems are interposed or are used instead of our regulators.

CAN A FAN BE USED TOGETHER WITH AN AIR CONDITIONER?

Yes definitely.

By using a fan in conjunction with an air conditioner, one can reduce the workload and energy usage of the air conditioner by as much as 20% – 30%. This is a huge savings considering that a fan uses less than 5% of the energy of an air conditioner.

DOES A FAN HELP TO REPEL MOSQUITOES AND OTHER FLYING INSECTS?

Yes. Mosquitoes and flying insects don’t like the draft.  But that is not to say that some determined mosquitoes will not manage to get through and attack you!

TROUBLESHOOTING

WHAT IS COVERED BY THE FAN WARRANTY?

Warranty/Guarantee applicable to purchasers in South Africa.

MY FAN IS MAKING A RASPING OR CLICKING NOISE AS IT TURNS. WHAT BASIC CHECKS CAN I CARRY OUT BEFORE CALLING IN THE ELECTRICIAN?

Check that the bolt securing the down rod to the motor shaft is securely tightened (No. 10 spanner)

Check the same for the bolt at the ceiling side for the down rod to the shackle assembly.

Check that the fans blades are securely tightened to the motor with the Allan key provided.

Check that the cup over the motor is not touching the motor and causing a vibration. Lift it slightly away from the motor.

Check that the top cup is firmly pressed against the ceiling and securely tightened.

Do not attempt to disassemble the fan or the motor unless you are a qualified installer. To do so, may invalidate the warranty.

MY FAN IS HUMMING OR THE MOTOR IS NOT RUNNING. WHAT COULD BE THE PROBLEM?

It may be that the Capacitor unit is faulty or that it may have blown. In this case it is a simple and cheap matter to fix by replacing the capacitor. Speak to your electrician and ask him/her to inspect and test the capacitor before carrying out other expensive work.

MY FAN IS WOBBLING. WHAT CAN I DO ABOUT THIS BEFORE NEEDING TO CALL IN THE ELECTRICIAN?

In the unlikely event that your fan is wobbling after installation, or after a period of time, there is a way to attempt to re-balance the unit.

  • Switch off fan
  • Use a measuring tape or a carpenter’s square to measure the distance between ceiling and the tip of fan blade as shown below.
  • Mark on tape or square and repeat with other two blades.
  • Carefully bend blade(s) at bracket in the required direction until all three blades measure precisely the same distance to ceiling.
  • Switch on the fan and check to see if it is now running smoothly and without any wobble.

ABOUT US AND OUR FANS

HOW QUIET ARE YOUR FANS?

We believe our fans are amongst the quietest available anywhere.

Every fan we make is tested electronically for noise levels according to very strict tolerances.

Some level of noise is inevitable with any fan at higher speeds, but at the lower speed positions 1 and 2, our fans should be whisper quiet. Exactly what you would expect from a fan of this quality!

WHAT MAKES A FAN FROM TIMBER FANS, DIFFERENT FROM OTHERS ON THE MARKET?

Most fans available from the discount store are mass-produced items, generally with aluminium fan blades, metal finishes and cheap motor components. Predictably, many of these are prone to wobble and noise.

Our fans are individually handcrafted, tested and balanced before being passed as ready for delivery to our customers. We use only the best materials available locally or imported where necessary. For our imported motors, we go the extra step of replacing the standard bearings with aircraft-quality Swedish bearings thereby ensuring longer service life and extra quiet performance. We are the pioneers of the self-ventilating hub on our Classic, Contemporary and Pearl ranges which also reduces operating temperature to prolong service life. More recently we have developed the Aero-glide timber blade which improves performance by up to 20% compared to other timber blades.

Our R&D efforts are lead by our Technical Director with over 50 years experience in ventilation and refrigeration engineering.

When it comes to classical style and timeless elegance, our fans lead the way and are certain to enhance the decor and beauty of your home and living spaces.

DOES TIMBER FANS HAVE AGENTS IN THE MAJOR CENTRES?

A number of lighting and home decor stores around the country do sell our fans and display a limited number of our models. However, because of the wide range of finishes and styles that we offer, it is generally not practical for dealers to display very many models or to carry stocks.

Should you be looking for an agent in your area, please call us and we will gladly give you a referral to your closest dealers.

Customers are free to deal with any of our dealers or to buy directly from us.

CAN TIMBER FANS BE USED OUTDOORS?

Our fans are not intended for outdoor use.

They can be installed under covered patio areas provided they are fully protected against wind or water damage.

WHY DON'T TIMBER FANS HAVE A REVERSE FUNCTION FOR WINTER?

It is not necessary to have a reverse function on a fan as some fan suppliers might claim. By creating a down-draft or side-draft a fan is forcing the circulation of all the air in the room and this includes the warm air that would otherwise tend to be trapped in the upper reaches of the room. This results in the warm air being distributed more evenly throughout the room thereby raising the temperature of the air closer to ground level.

ARE THE FAN BLADES MADE FROM SOLID TIMBER?

Most of our timber blades are made from superior quality 4 – 5 ply marine ply veneered with two layers of selected timber veneer to give a 4mm -6 mm thick finished blade.

Solid timber blades can be prone to warping, shrinkage or splitting and would not be suitable for many areas particularly extreme weather and dry environments.

Our wooden hubs on the other hand are cut and machined from solid timber which has been carefully selected and seasoned before being fashioned into a fan hub.

WHERE CAN I BUY ELECTRICAL ACCESSORIES SUCH AS WALL MOUNTED CONTROLS AND REMOTE CONTROLS FOR MY FAN?

You can buy the electrical accessories from the agent through whom you bought the fan in the first instance, or if they are not able to assist, you can contact Timber Fans directly through the Contact page on our website or by telephoning us.

WHAT ARE YOUR NORMAL LEAD TIMES IF I PLACE AN ORDER?

Depending on the type timber selected and the finishing options chosen, we can normally ship from between 14- 21 days from order placement. However, our door is always open to discuss urgent requirements that you may have. It needs to be remembered that all orders are made to individual customer specification and are not drawn from stock.

DO YOU DELIVER?

We ship throughout Southern Africa and worldwide. Our appointed freight couriers can deliver to most local destinations within 24 – 48 hours, and for export orders we provide delivery schedules and price quotes for customer approval.
