Room size and use of the room
There are no hard and fast rules about selecting the size or appearance of a ceiling fan. However, its very important to consider the size of the room when selecting a ceiling fan as this is the starting point for determining what overall fan-size diameter is required. The larger the room is, the larger the overall ceiling-fan diameter needs to be in order to generate enough air movement and create a cooling breeze. The blade pitch is also very important. The greater the blade pitch on the ceiling fan, the greater the volume of air that will be circulated. Most importantly, as the overall diameter and blade pitch increases on all Martec ceiling fans, so does the size of the motor used, as there is a much greater resistance put on the motor. Many other ceiling fan suppliers do not always follow this basic principal.
Ceiling Fan Size Recommendations
Room Dimensions Suggested Ceiling Fan Size
- Up to 12 Square Metres (3.5m x 3.5m small bedroom) 1067mm (42")
- Up to 18 Square Metres (4m x 4.5m medium bedroom small living area) 1200mm (48")
- Up to 30 Square Metres (5m x 6m large bedroom, large living area) 1300mm (52")
- Up to 40 Square Metres (6.5m x 6.5m rumpus room, large living area) 1400mm (56")
Large Rooms – Living, family or master bedrooms need a ceiling fan with an overall diameter of 1300mm or larger to generate enough airflow. A small fan in a larger room can do three things: Make the room look smaller; produce airflow in only a small area; and, create an unbalanced look in the room.
Small to Medium rooms – For kitchens, dining rooms, childrens bedrooms and offices you should choose a fan sized 1200mm or smaller.
Outdoor Areas – All of Martecs ceiling fans are NOT waterproof or IP65 rated, and thus cannot be directly exposed to the elements. Martecs Precision 316 which is constructed entirely from Marine grade stainless steel 316, is the only fan Martec recommends for continued outdoor use. Exposure to the elements, sand, dust and/or salt in the air can dramatically reduce the performance of all of Martecs ceiling fans, with the exception of the Precision 316.
For all coastal areas the Martec Precision 316 is the only ceiling fan series available where the entire exterior construction of the fan down to every last screw is made from the highest grade 316 stainless steel. It is not a blended material construction fan offered by other brands that claim offer the full 316.
If you have high ceilings above the standard 2.4 metres, you may require an extension rod-- which can be purchased separately--to lower the ceiling fan. The full range of Martec and FourSeasons ceiling fans have the ability to add an extension rod (which much be purchased separately). The standard extension rod size is 900mm (1800mm rods also available) but it can easily be cut to suit your requirements by the installing electrician. All Martec and FourSeasons ceiling fan extension rods also come with the required appropriate wiring lumes, to make extending the wires from the fan motor to the connection point a simple plug-in system, for easier installation.
All Martec and FourSeasons ceiling fans come with a Hang-Sure Canopy fixing method to the ceiling which means that ceiling fans can be mounted on sloping or cathedral ceilings of up to 30 degrees, and, of course, on flat ceilings as well.
Recommended Installation Height
All ceiling fans should be at least 2.1 metres from the floor to the blades of the fan and at least 300mm from the ceiling. The greater the distance from the ceiling to the fan blades, while still maintaining the 2.1 metres from the floor, the greater the volume of air that will be circulated.
Motor Speed & Blade Pitch
Most ceiling fans operate at a top speed of 200 RPMs. Motor speed, size and blade pitch are the determining factors in the amount of airflow that will be created by the fan. Martecs ceiling fan line has many models, with the pitch varying from between 12 degrees to 23 degrees for high-performace applications and large volumes of air movement. All of the motors that we incorporate in our fans are suited to the overall fan diameter and blade pitch to provide maximum performance and years of hassle-free operation. Our motors are among the finest available, with lamination-reduction technology for quieter operation, and milled edges--not pressed. All of our start-run capacitors are doubled sealed and temperature treated to ensure smooth speed transitions, and ensure whisper-quiet operation.
Additional Lighting Source
If your fan will be replacing the main light in a room (which is the case with most remote-control fans) you will need to purchase a ceiling fan that has an integrated lighting fitting. Most Martec Ceiling Fans are light adaptable so you can still retain your light source, if placing the fan in the centre of down-lights or other lighting sources. If you are using down-lights to illuminate your room and place a Ceiling Fan in the centre of these, it is very important that the fan blades are well clear of the down-light beams to avoid creating a strobing effect. Martec also offers many models of ceiling fans with dedicated energy-saving light sources, including the technology available to dim them.
Have the convenience of being able to control the light and action of your fan from a remote control. The Martec LCD Remote Control Kits have many handy features such as 1-9 hour timer, light dimmer, and light delay, as well as controlling the fan speeds and light on/off function. Most Martec ceiling fans can be installed with a remote-control kit, which means there is no need to run an extra wire to control the fan, as the remote does everything for you. Remote controls are an optional extra, although some ceiling fans in our line do have them included as part of the package.
