Why AC Infinity Fans Use EC Motors with PWM Technology


When it comes to selecting the right motor for your ventilation needs—be it for a hydroponic setup or a home project—not all motors are created equal. Today, we'll dive into why Electronically Commutated (EC) motors, particularly those with Pulse Width Modulation (PWM) as used by AC Infinity, are a cut above the rest.

EC Motors Explained

EC motors combine the advantages of AC and DC motors, using electronics to convert the AC voltage to DC for enhanced performance. What sets AC Infinity's EC motors apart is the use of PWM, a method that allows for more precise control of motor speed and function.

DC and AC Motors: A Quick Comparison

DC motors are efficient but offer limited control features, while AC motors are less efficient and noisier. EC motors—especially those with PWM—address these limitations and offer further advantages.

The Big Benefits of EC Motors with PWM

Efficiency and Energy Savings

EC motors with PWM can adjust their speed to the task, consuming up to 30% less energy than their DC and AC counterparts.

Versatility in Control

The use of PWM allows for advanced control features, making it easier to maintain specific environmental conditions.

Noise Reduction

EC motors with PWM operate more quietly than either DC or AC motors, reducing both noise pollution and stress.


The smart operation of EC motors with PWM can extend the lifespan of your ventilation system, saving you money in the long run.

Why AC Infinity Stands Out

AC Infinity utilises PWM in their EC motors for exceptional control and efficiency, setting them apart from competitors. Their fans offer versatile, advanced control options, making them ideal for a multitude of applications.

Applications Beyond Hydroponics

While these motors are exceptional for hydroponic setups, their benefits extend to other applications. Whether you're a tradesperson looking to install a robust home ventilation system or a homeowner aiming to reduce mould and improve air quality, AC Infinity's EC motors with PWM are the smart choice.

EC motors equipped with PWM technology offer unparalleled advantages in efficiency, control, and longevity. When it comes to brands that make the most of this technology, AC Infinity leads the way.
