Component Specifications

Definition
A fan guard is a safety component designed to enclose the rotating blades of an air-cooled fan, preventing accidental contact with moving parts while maintaining adequate airflow for cooling purposes. It typically consists of a rigid frame with mesh or grille patterns that balance protection with ventilation efficiency.
Working Principle
The fan guard operates on the principle of physical barrier protection. Its open design allows air to pass through while creating a protective shield that prevents objects, debris, or personnel from contacting the rotating fan blades, thereby reducing injury risks and preventing foreign object damage to the fan assembly.
Materials
Typically made from galvanized steel, stainless steel, aluminum alloys, or engineered plastics (such as ABS or polycarbonate) with corrosion-resistant coatings where required.
Technical Parameters
  • Mesh Size 5-20 mm typical
  • Wire Diameter 1.5-3.0 mm
  • Frame Thickness 1.0-2.5 mm
  • Protection Level IP20-IP54
  • Airflow Reduction <15%
  • Temperature Range -20°C to 120°C
Standards
ISO 14120, DIN EN ISO 13857
