8318 ebmpapst 48V 80mm 3300RPM 3W DC Axial Fan

Description

The ebmpapst 8318 is a high-performance 48V DC Axial Fan with dimensions of 80 x 80 x 32 mm, engineered for stable cooling in demanding industrial environments. Operating within a voltage range of 36-56 VDC, this unit delivers an airflow of 54 m³/h at a nominal speed of 3300 RPM, optimized for energy efficiency with a power consumption of 3 W and a current draw of 63 mA. The fan features a glass-fiber reinforced PBT plastic housing and a PA plastic impeller, utilizing a high-precision ball bearing system for an extended service life of 70,000 hours at 40 °C. It is equipped with comprehensive electronic protection, including reverse polarity, blocked-rotor, and overload protection. With an operating temperature range up to 75 °C and a variety of customizable control options (such as PWM, Speed Signal, and IP54/IP68 protection), the 8318 is a versatile and reliable thermal management solution for telecommunications and power electronics.

[Application]
The ebmpapst 8318 is specifically designed for 48V DC telecommunications and industrial systems where a balance of moderate airflow and high static pressure is required. Its 32mm depth provides better pressure characteristics than thinner fans, making it ideal for cooling dense 48V power supply units, network switches, and industrial controllers. The ultra-low power consumption of 3 W and 63 mA current draw make it an excellent choice for energy-efficient or battery-backed systems. With a long service life and high-temperature tolerance (up to 75 °C), it ensures 24/7 reliability in mission-critical infrastructure.
