["【Flexible Speed Control】Powerful fan with external speed controller. You can choose any speed from 0-100% with the included variable speed controller, without generating background noise or humming at low speed.","【Stable Performance】Air flow rate: 683m³/h, Speed: 2800 RPM, Power: 55W, By using three-phase motors, the work efficiency is more stable. Even if the duct is longer than 10 meters, the duct fan can work normally without reducing power and air volume. There is no gear limitation, free adjustment, and more energy saving.","【Three-phase EC Motor】Power saving is very good: EC motors with mixed flow design. This allows the built-in fan to run more quietly and achieve low speeds without generating noise or heat. The energy efficiency of EC motors is also twice as high, and can save up to 40% of energy costs and recover costs in the long run.","Multi-application Places: The adjustable 150mm duct fan is suitable for a variety of places that require better air circulation, such as laundry rooms, 3D printers, laser engraving machines, basements, attics, garages, grow tents, activated carbon filters, etc.","【Guarantee】For our products, we offer new replacements instead of repairs within the warranty.
