Which type of fan is better for me? Are DC fans better for my power bills or are AC fans still the way to go? Will DC cost me a small fortune initially?
All good questions!
In general, DC fans have the following advantages:
- Up to 80% energy savings over standard fans
- Better airflow
- Whisper quiet operation (NO humming!)
- Sleek, modern designs
- Remote control operation
Lets look at some reasons as to why....
So, what is the difference between an AC and a DC fan?
Concerning ceiling fans, there are two primary types of motors, known as Alternating-Current (AC) and Direct-Current (DC) motors. In AC fans, the flow of electric charge periodically reverses direction, which is most probably not unlike many of your household electrical appliances. In direct current (DC), the flow of that electric charge is only in one direction.
The difference between the two types of motors and how they operate a fan, is simple:
AC motor fans operate by being connected directly to standard power, which is what creates the energy and force needed to run the fan's motor. DC fans however, like Mercator's Grange DC and Brilliant's Galaxy DC, have an in-built transformer which converts the standard power to DC. The effect is that it decreases the amount of power used on all fan speeds, as the fan is only utilising a direct current instead of an alternating current.
So how do DC fans actually provide BETTER airflow than AC fans, using less power?
Generally, DC fans have an in-built network of permanent magnets that go hand-in-hand with the motor in order to create the force required to spin the blades, subsidising for lower power available. They are the DC motor's 'wingman', installed as such so that they reduce the amount of energy needed to create the same level of 'work' as an AC fan. Oftentimes, DC fans actually produce faster spinning on high speeds= better airflow!
On high speed, AC fans consume about 60-120 watts, whereas DC fans generally use between 30-40 watts only.
What other advantages to DC fans have over AC fans?
Besides offering as good (mostly better) airflow at much lower power consumption than AC fans, DC fans also operate with NO motor noise (that's right, none). This makes them even better for bedrooms and living areas, where you don't want to be disturbed by a humming fan motor!
DC fans are also operated via a remote controller, adding a high level of convenience to your ceiling fans.
How do I know if a fan is DC or AC?
If a fan is DC, it will be specified in the title of the fan i.e. 'Grange DC ceiling fan'. If it is not specified that it is a DC fan, then it is an AC fan.
OK, so where do I go from here?
Selecting any ceiling fan involves a variety of factors which should influence your decision. From your budget to your decor, it will take more than some stats to make you buy a fan. However, the main points between AC and DC are as follows:
- DC fans are a newer technology and are definitely the way of the future- they consume LESS power but produce better airflow.
- DC fans are generally more expensive than AC fans.
- AC fans are still extremely efficient and are still a great fan choice, as most AC fans cost less to run than a couple of halogen downlights anyway!
OUR RECOMMENDATION- DC fans are the way of the future. Go DC for better airflow with less consumption. It is the ultimate option in terms of room cooling at very low cost. With their sleek design, they look great, too!
We hope that we have helped you in terms of deciding between AC and DC fans. Happy shopping!
