Q&A

A: Reduced air motor speed or unstable AODD pump flow is typically related to air supply conditions, exhaust restriction, or component wear. Common causes include:

  • Inlet Pressure Stability: Ensure the air supply meets rated specifications. Pressure fluctuations directly impact output consistency.
  • Muffler Maintenance: Dust, moisture, or oil buildup in the muffler may create backpressure and reduce efficiency.
  • Component Wear: Worn vanes or diaphragms can lead to air leakage and reduced operating efficiency.
Note: If performance issues persist, please contact TFL for support.


  • Selection Support: Optimal pump advice based on fluid properties and pressure requirements.
  • Application Consulting: Specialized solutions for high-viscosity media (e.g., resins, coatings), including piping and pressure setup.
  • After-Sales Support: Troubleshooting and recommendations for spare parts.
A: Recommended maintenance follows the “Dry, Clean, Lubricated” principle:
  • Air Quality: Use of an FRL unit (Filter-Regulator-Lubricator) to remove excess moisture and particles from the air supply.
  • Lubrication: Consistent lubrication with pneumatic-grade oil to reduce internal friction and extend component life.
  • System Maintenance: Periodic flushing, especially after handling fast-curing or high-viscosity fluids, to prevent internal material buildup.
  • Pneumatic Power Source: Powered by compressed air, allowing flexible operation in various industrial applications.
  • Stall-Safe Design: Stall capability under excessive load without overheating or damage, with automatic restart once the load is reduced.
  • Variable Speed & Self-Cooling: Simple speed management via airflow regulation. Air expansion helps provide a natural cooling effect during operation.
  • Chemical Industry: Handling of acids, alkalis, and various chemical fluids.
  • Surface Finishing: Furniture and metal coating lines (e.g., Airless Paint Sprayers).
  • Food & Pharma: Reliable performance in high-humidity or wash-down environments.
  • Industrial Automation: Power source for mixers, agitators, and high-cycle production lines.
