Product Specifications

Technical details and manufacturing context for Ventilation Fan

Definition
A ventilation fan is an essential component of a control system cabinet that actively moves air to regulate internal temperature, prevent overheating of sensitive electronic components, and remove dust or contaminants. It ensures optimal operating conditions for control systems by maintaining proper airflow and thermal management.
Working Principle
The ventilation fan operates by converting electrical energy into mechanical rotation of fan blades, creating airflow through the cabinet. This airflow facilitates heat transfer from internal components to the external environment, preventing thermal buildup and maintaining stable operating temperatures.
Common Materials
Plastic, Aluminum alloy
Technical Parameters
  • Fan diameter and mounting hole dimensions (mm) Standard Spec
Components / BOM
  • Fan Blade
    Creates airflow through rotational motion
    Material: Plastic
  • Motor
    Provides rotational power to drive the fan blades
    Material: Copper windings, steel casing
  • Mounting Bracket
    Secures the fan to the cabinet structure
    Material: Steel
Engineering Reasoning
0.5-2.5 m³/min airflow at 100-240 VAC, 50-60 Hz, 0.2-0.8 A, -10°C to +55°C ambient
Bearing temperature exceeding 120°C, airflow dropping below 0.3 m³/min, vibration amplitude surpassing 4.5 mm/s RMS
Design Rationale: Grease degradation at 120°C causes lubricant film breakdown, leading to metal-on-metal contact and bearing seizure
Risk Mitigation (FMEA)
Trigger Electrostatic discharge exceeding 15 kV accumulating on fan blades
Mode: Motor winding insulation breakdown causing phase-to-phase short circuit
Strategy: Conductive polymer blade coating with surface resistivity <10⁹ Ω/sq and grounding path to chassis
Trigger Particulate contamination exceeding 0.5 mg/m³ of PM10 particles
Mode: Bearing raceway abrasion increasing friction torque above 0.02 N·m
Strategy: IP54-rated sealed bearing housing with labyrinth seals and positive pressure purge system
