Delock Axial Fan 80mm 48V DC 4-Pin PWM Ball Bearing Black

An 80 mm axial fan engineered for dependable cooling in industrial and IT environments, this Delock unit pairs a 48 V DC power input with PWM speed control to deliver precise thermal management. The fan adjusts from 500 to 3000 RPM, producing airflow up to 57.9 CFM while keeping noise to a maximum of 35 dB(A).

Advantages

A durable ball bearing extends service life to 70,000 hours at 40 °C, and the PBT plastic frame and impeller withstand demanding conditions. PWM support enables automatic speed adjustment based on system load, reducing energy use and acoustic output. The 30 cm cable with a 4-pin PWM connector simplifies integration into existing setups.

Suitable for

• Cooling of network switches, routers, and servers
• Ventilation in control cabinets and industrial enclosures
• Replacement fan for IT and audio equipment
• Custom DIY projects requiring reliable airflow
