AC Fans are one of the most reliable and efficient components for cooling electronic components and systems found in today’s technology devices. To ensure proper and effective cooling, AC fans must be selected with the correct capacity, specific motor type and proper speed control.The 3950M family of AC fans is an excellent choice for providing reliable cooling within a wide range of applications. They feature proven longevity and long-term success within applications ranging from commercial HVAC (heating, ventilation, and air conditioning) systems to industrial server rooms. The 3950M fans offer dependable cooling performance with up to 40,000 hours of continuous operation, and their utiloty within the HVAC and server room context makes them a highly sought after component.The 3950M series utilizes a combination of speed, air volume, and power to provide an effective cooling solution. This fan features a brushless DC motor which has been developed to improve both efficiency and performance while reducing maintenance overhead. The DC motor utilizes a permanent magnetizing field to excite the rotor coils and generate a current, which drives the motor and fan blades. By sizing the N- and S-pole magnetic gaps precisely and varying the current, the motors allow for enhanced speed control and, thus, the desired air flow and cooling effect.Using a two-stage backstop control and signal input, the 3950M fans can be adjusted to match the specific demands of the application. The units are equipped with short circuit protection and feature an overload trip circuit which prevents motor damage or lockup during operation. This allows the 3950M to be immune to vibration and rapid heating/cooling cycles—features which are essential to maintain stability in commercial and industrial settings.The 3950M also offers users an updated fan configuration featuring two diagonal fan blades. The blades are designed for maximum airflow and minimal noise, providing quieter operation than traditional fans while quickly dispersing heat from the components or system. Furthermore, the 3950M series allows for customization with user-selected frames, guards, mounting options, and other accessories.The 3950M series of AC fans are an excellent choice for providing reliable cooling in HVAC and server room applications. With their powerful and customizable design features, they can quickly disperse heat while delivering excellent air flow and minimal noise. The two-stage backstop control, short-circuit protection, and overload trip circuit provide stability and reliability for users in the event of sudden power fluctuations or temperature changes. Additionally, the series offers customizable options that suit the specific needs of the application, making it a highly efficient and cost-effective cooling solution for commercial and industrial spaces.
