4715KL-05W-B39 NMB Cooling Fan

Product Description

The NMB 4715KL-05W-B39 is a dependable DC axial fan engineered for high airflow performance in compact spaces where cooling efficiency and durability are essential. Operating at 24V DC and drawing just 0.40A, it offers an impressive balance between power consumption and airflow output, making it ideal for industrial systems that demand consistent thermal control. With a maximum airflow of approximately 108 CFM, this fan ensures adequate ventilation even in tightly packed electronics or high-heat environments. The ball bearing construction enhances its operational lifespan, allowing for continuous use in mission-critical applications such as network servers, power inverters, or automation equipment. Designed to fit standard 120mm fan mounts, its 38mm depth provides enough blade clearance for strong air movement while maintaining a relatively low noise level of 42.5 dB(A). It supports a broad temperature range from -10C to +70C, making it suitable for both indoor and semi-industrial use. Though the fan is no longer in active production, its performance profile remains a benchmark for selecting modern replacements in systems where reliability and airflow are non-negotiable.
