Fan regulators are often labeled with settings from 1 to 5 to indicate increasing speed, with 1 being the lowest and 5 the highest. This design reflects a user-friendly approach, allowing users to easily identify and select the desired speed level intuitively. The ascending order aligns with common practices in consumer products, where higher numbers typically signify greater intensity or output. Hence, the numbering facilitates quick adjustments while using the regulator.
