The blowing system is a core component that determines the cleaning efficiency and equipment lifespan in laser cleaning processes. Proper configuration of blowing parameters can improve overall performance by over 30%. This article explains the key functions, technical specifications, and operational guidelines for the blowing system.

Laser Cleaning Machine Blowing System

Core Functions of the Blowing System

  1. Efficient Contaminant Removal
    Removes smoke and debris generated during laser cleaning in real time, preventing recontamination of the workpiece surface or obstruction of the laser beam.
  2. Optical Component Protection
    Creates a protective “air curtain” via directed airflow to block splatters from reaching lenses, extending their lifespan.
  3. Process Enhancement
    Enhances laser energy concentration on target areas (e.g., oxide layers, grease), improving stripping uniformity.

Technical Requirements

  1. Gas Type Selection
    Scenario Recommended Gas
    General Use Dry, oil-free compressed air
    Flammable Materials Nitrogen
  2. Pressure & Flow Control
    • Pressure Range: 0.2–0.8 MPa
      • Low pressure: Ideal for precision cleaning or thin contaminants.
      • High pressure: Suitable for stubborn stains or large particles.
    • Flow Matching: Must be synchronized with laser power and scanning speed.
  3. Nozzle Angle & Position
    • Angle: 30°–60°（Relative laser beam）
    • Positioning: Cover the cleaning area while avoiding direct airflow toward lenses.

 Operation & Maintenance Tips

✅ Daily Checks

  • Ensure no nozzle blockage or air leakage.
  • Monitor pressure stability (fluctuation <±5%).

✅ Regular Maintenance

  • Clean filters weekly; replace high-precision filter cartridges (0.01 μm) quarterly.
  • Record lens contamination frequency to optimize blowing parameters.

⚠️Common Issues & Solutions

Issue Solution
Uneven residue Adjust nozzle angle or increase pressure
Rapid lens contamination Check gas purity or upgrade filtration

Proper configuration of the blowing system is crucial for maximizing laser cleaning efficiency. Choosing a professional solution significantly reduces operating costs and extends equipment lifespan.
