Know before you buy
Yes, this low-speed model is specifically designed for quiet operation, producing 32 dBA of noise. While it is not silent, it is significantly quieter than high-speed industrial fans, making it a solid choice for AV cabinets or living spaces.
The fan comes with an included AC power cord, allowing you to plug it directly into a standard 100–120V wall outlet. It is ready to use right out of the box without the need for complex electrical wiring.
Yes, thanks to the dual-ball bearing system, this fan can be mounted in any direction—horizontally, vertically, or at an angle—without compromising its performance or lifespan.
The fan is rated for 67,000 hours of operation. If run 24/7, this equates to over seven years of continuous use, thanks to the durable dual-ball bearings and die-cast aluminum housing.
Yes, the kit is comprehensive. It includes the 120mm fan, a power cord, two metal fan guards for safety, and a set of mounting screws to secure the unit to your equipment or enclosure.
The motor features impedance protection, which helps the fan resist heat buildup if the rotor becomes locked. This safety feature prevents the motor from burning out in the event of an obstruction.
