AC vs DC Designer Ceiling Fans: Which One is Right for You?

AC vs DC Designer Ceiling Fans: Which One is Right for You?

There are primarily two types of designer ceiling fans AC and DC. DC ceiling fans use direct current (DC) electricity, whereas AC ceiling fans use conventional AC power. Which one is best for you, given that both have benefits and drawbacks? When deciding which type of ceiling fan to install in your home, we will explain the distinctions between AC and DC fans in this blog post.

It's important to note that the ceiling fan market is seeing an increase in DC ceiling fans. DC ceiling fans typically use less energy than other ceiling fans. However, many consumers are unsure of what "DC" fans are and whether using DC motor ceiling fans will actually save them money on energy.

Difference between AC and DC Designer Ceiling Fans?

The most popular model of ceiling fans uses conventional AC power. They are less expensive and simpler to install than DC ceiling fans. However, AC ceiling fans can be noisy, and they consume more electricity than DC ceiling fans.

DC electricity is used by DC ceiling fans. Although they cost more than AC ceiling fans, they are much quieter and use less energy. Additionally remote-controlled, DC ceiling fans are quite practical. DC ceiling fans might be trickier to install and are less prevalent than AC ceiling fans.

What kind of ceiling fan is best for you, then? AC is the way to go if you're searching for a less expensive solution that is simple to install. DC is a preferable option if you want a more energy-efficient and quiet option. In either case, ceiling fans can keep your house cool and cosy throughout the summer. If you're curious to learn more, keep reading as we examine the differences between AC and DC fans in further detail.

While AC fans can be turned on and off from a wall switch, a pull wire, or a remote, DC fans are often exclusively controlled by a remote. The chances of a remote being lost, broken, or having its batteries run out are higher. Some DC fans provide an optional wall controller as an added convenience; these can be purchased for an additional fee.

Decorative AC ceiling fans are more energy-efficient than the majority of home appliances because they only utilise 100 watts or less when operating at high speed.

The Pros and Cons of AC fans

AC fans are commonly used because the AC outlets are readily available in our houses.


They are inexpensive and have many styles and sizes available, easy to install.


  1. Variable flow

It is difficult to control the speed of the AC fans. The line frequency and partial amplitude of the AC voltage supply both affect how fast an AC fan runs.

It is completely impractical to change the AC voltage's frequency because doing so would incur very high conversion costs. In order to achieve the target cost of a speed-controlled AC fan, it is also expensive and most definitely not practical to change the amplitude and maintain the waveform of the AC Voltage source.

  1. More energy consumption

AC fans do consume more energy than DC fans. 

  1. More electromagnetic interference

When AC fans use "Phase Control" speed control techniques, there is more electromagnetic interference than when DC fans are used.

Average DC fans are more expensive than comparable AC models. The difference is small even though you consume less power and save money as a result. If you want the most recent in energy efficiency or an attractive, contemporary design, you should purchase a DC ceiling fan. Even so, AC models are still a better option if cost-cutting is your main driving force.

The Pros and Cons of DC fans

Ceiling fans for both homes and businesses can now use DC technology because it has recently advanced significantly. Permanent magnets are used in the motors of DC fans to electronically switch the attraction and repulsion of a rotor around the axis. Because DC technology is so much more recent than AC technology, there are fewer options available.


  1. Consumes less power

The most effective kind of supporters are often considered to be DC fans. Compared to AC fans, they use substantially less energy. In fact, compared to conventional AC fan types, DC fans use up to 70% less energy to produce the same output.

This means that a fan powered by 25 watts of DC has the same effect as one powered by 100 watts of AC. This is perfect for commercial settings, such as restaurants, as it enables you to run fans continuously without incurring exorbitant electricity costs.

  1. Minimal electromagnetic interference

Designer DC ceiling fans have less electromagnetic interference because of the low power consumption and use of advanced electronic switching. DC fans are frequently used in sensitive electrical devices to reduce electromagnetic interference.

For instance, computer equipment and applications depend on DC fans to prevent overheating while also reducing electromagnetic interference that could adversely affect delicate applications.

  1. Lower voltage

Compared to AC fans, DC fans typically utilise less voltage. Low-voltage fans make up the vast bulk of DC fans. DC fans, for instance, typically come in 5V, 12V, and 24V variations. Larger DC fan models, like those ranging from 119mm to 172mm, are typically offered in 48V. In contrast, the majority of AC cooling fan models are offered at 115V, a significantly higher voltage. DC fans may also be less dangerous due to lower voltage.

  1. Water-Resistant

The DC fans can be used in extreme environmental applications. To ensure the safety of your equipment and employees, you must use a dependable, high-quality water-resistant model.

Our harsh weather fans are made with an eco-friendly proprietary conformal coating that has excellent properties and corrosion resistance, allowing them to withstand dust, moisture, water exposure, and even full immersion. Our DC fans are also vacuum sealed, which allows them to operate even when submerged.

  1. Variable flow

The DC fan can provide a variety of speed control features at a modest additional cost, allowing the fan to fulfil the airflow target of a given application. The fan can be operated by:

  • Voltage
  • Current
  • Temperature
  • Resistance
  • PWM signals

By adjusting the fan speed as needed, the fan's life can be extended while keeping the acoustical airflow noise to a bare minimum.


May require an AC-to-DC converter

An alternating voltage source powers the AC fans. A steady voltage source powers the DC fans. This means that the DC fan must have an AC-to-DC converter, either externally or internally, to convert AC voltage to DC voltage in order to power the DC fan.

AC vs. DC: Which Fan Is Right for You?

The final truth is that the best fan for you will be determined by your individual requirements. Before buying an AC or DC designer ceiling fan, carefully consider the advantages and disadvantages of each type of fan.
