Loam-Mit-Thai-RestaurantKedahDC technology has become much more sophisticated in recent years, and it can now be applied to both residential,industrial and commercial areas. DC fans have motors that rely on permanent, built-in magnets in order to attract and repel a rotor around an axis joined with invertors.


Minimal electromagnetic interference

Because the electromagnetic interference of DC fans is minimal, sensitive electronic devices often use DC fans to prevent electromagnetic interference. For example, computer applications and equipment rely on DC fans, as they prevent overheating while still minimizing electromagnetic interference that could negatively affect sensitive applications.

Consumes less power

DC fans are widely regarded as the most efficient type of fan. They consume significantly less power than AC fans. In fact, DC fans consume up to 70 percent less energy to produce the same output as other fan types. For example, that means that a 25-watt DC-driven fan uses the same power as a 100-watt AC-driven fan. This is ideal for commercial settings, like restaurants, allowing you to keep fans running all day without incurring astronomical electric bills.


DC fans make use of a new type of electrically commutated motor (ECM). Not only are these motors ultra-efficient, they are also incredibly quiet. Because they are so quiet, DC fans are an excellent option for applications such as medical instruments, telecom switches, or car entertainment systems, where noise could be a nuisance.

Lower voltage

DC fans generally use less voltage than AC fans. The majority of DC fans are low-voltage fans. For example, you can typically find 5V, 12V, and 24V versions of DC fans. Larger models of DC fans, such as 8ft to 14ft fan models, are typically available in 220V . In comparison, most AC cooling fan models are available in 220V,380V, a much higher voltage. Lower voltage also makes DC fans potentially less dangerous.

Water Resistant

When DC fans must be used in these types of severe conditions, it’s imperative to employ a reliable, high-quality water-resistant model to ensure the safety of your equipment and staff.

OPT HVLS BLDC momtor fans has been designing, developing, and manufacturing industry-leading axial AC and brushless DC fans for more than 11 years. This includes a wide range of severe weather and water-resistant fans, which offer unparalleled dust and water protection while meeting military and NASA material specifications,CE certifications, and UL certifications.

Our harsh weather fans feature an eco-friendly proprietary conformal coating with excellent low friction properties and corrosion resistance, allowing the fans to easily withstand dust, moisture, water exposure, and even full water immersion. Our DC fans also undergo a rigorous vacuum sealing process, enabling them to operate during submersion.

Characteristics of AC fans

AC fans are commonly used when consistent and even airflow is required. These fans are commonly used in domestic appliances.

The major advantage of AC fans is that they provide an even, constant flow. An AC fan will move warmer air away from the components of the fan and then draw cooler air over them.

For example, Pelonis' AC Fans aid in their focus of high-end beer dispensing equipment. Our fans are doing their part to keep the beer cold when coming out of the tap at restaurants and hotels.
