  • Ultra-quiet static-sound design reduces audible noise
  • 40 × 40 × 20 mm frame fits tight equipment bays
  • Low 0.06 A draw minimises power consumption

Compact 12 V cooling fan for tight enclosures

This 4020 frame fan runs on 12 V DC and draws only 0.06 A making it suitable for low-power inverter or equipment cooling where space is limited. Its 40 mm square footprint fits small chassis or custom brackets without requiring large cutouts. Builders needing higher airflow or larger mounting patterns should look elsewhere.

Ultra-static sound profile for quiet operation

The RDL4020S is described as ultra static sound meaning it aims for minimal acoustic disturbance during continuous use. A 20 mm thickness keeps the profile slim so it can sit behind panels or inside shallow ducts. The unit ships as an international power cord category item so the connector is a standard mains lead rather than a PCB header.
