Air Assist Adjustable 30 L/min Air Pump Kit — For 20 W Laser Engravers & Cutters

Get cleaner cuts, brighter engraves, and less flare-up with a 30 L/min adjustable air-assist kit purpose-built for 20 W diode and small CO₂ laser machines. A focused airflow clears smoke and debris at the kerf, reducing char, protecting optics, and improving throughput.

Key Features

• Adjustable Flow up to 30 L/min
  Front-panel knob (and clear gauge on select versions) lets you dial airflow from delicate engraving to aggressive cutting.
  
• Stable, Oil-Free Diaphragm Pump
  Continuous-duty design delivers dry, pulse-free air—no oil fog, minimal maintenance, long service life.
  
• Quiet Operation
  Vibration-damped feet and internal muffling keep noise down for desktop shops and makerspaces.
  
• Complete Hookup Kit
  Includes silicone/PVC airline, barb adapters (common 4/6/8 mm), nozzle/air-assist head (model-dependent), and mounting hardware for fast install.
  
• Inline Filtration
  Particulate/moisture filter helps keep lenses and mirrors cleaner; transparent bowl for quick checks.
  
• Universal Compatibility
  Works with popular 20 W diode engravers (air-assist port or add-on nozzle) and small CO₂ units—check nozzle size and bracket style.
  

Benefits You’ll Notice

• Cleaner edges, less char & soot on plywood, MDF, leather, acrylic, and paper.
  
• Fewer flare-ups and better cut-through on thicker sheets.
  
• Sharper engraving contrast by clearing smoke from the beam path.
  
• Longer optics life with reduced contamination on lens/shield.
  
• Higher throughput—run faster speeds or fewer passes with consistent cooling.
  

Typical Specifications (may vary by kit)

• Flow Rate: 0–30 L/min adjustable
  
• Pressure: 0–0.03 MPa (≈0–4.3 psi) typical for diode lasers
  
• Pump Type: Oil-free diaphragm, continuous duty
  
• Noise: ~40–55 dB(A) at 1 m
  
• Power: 100–240 V AC, 50/60 Hz (US/EU plugs available)
  
• Ports: 6 mm (1/4") barb outlet with adapters for 4/6/8 mm line
  
• Accessories: Inline filter, hose, clamps, nozzle/holder (where included), anti-vibration feet
  
• Duty Cycle: 100% at nominal flow; allow cool-down for extended max-flow sessions
  

Installation (Quick Guide)

1. Mount Pump on a level surface; fit vibration pads.
   
2. Plumb Air Line from pump → filter → laser’s air-assist nozzle (or included bracket/nozzle).
   
3. Secure Hoses with the supplied clamps; avoid sharp bends.
   
4. Power On & Set Flow: Start with low flow for engraving (e.g., 5–10 L/min); increase toward 20–30 L/min for cutting.
   
5. Test Cut: Adjust flow to balance edge quality, cooling, and smoke evacuation.
   

Use & Tuning Tips

• Engraving: Low-to-moderate flow preserves shading while keeping smoke off the lens.
  
• Cutting: Higher flow improves kerf clearing on plywood/acrylic—watch for part movement on lightweight stock.
  
• Keep Filters Dry/Clean: Drain condensation; replace elements as needed.
  
• Pair with Extraction: Air assist is not a substitute for fume extraction—always vent or filter fumes.
  

Safety

• Vent fumes from wood/resins/plastics to the outdoors or a proper filter.
  
• Avoid cutting PVC/vinyl—toxic chlorine gas can form.
  
• Eye protection and enclosure interlocks recommended.
  
• Keep the airline clear of the gantry path; secure with cable clips.
  

In the Box

• 30 L/min adjustable air pump (oil-free)
  
• Inline moisture/particulate filter + brackets
  
• Silicone/PVC air hose, barb adapters, clamps
