Scavenge Line Maintenance for Atlas Copco GA VSD+ Compressors

Scavenge Line Maintenance for Atlas Copco GA VSD+ Compressors

The scavenge line in your Atlas Copco GA VSD+ compressor might not get much attention, but it plays a critical role in keeping your system efficient and oil consumption low. Neglecting it can lead to higher oil carryover, poor separator performance, and increased maintenance costs.

What Does the Scavenge Line Do?

The scavenge line returns separated oil from the air/oil separator vessel back into the compressor's oil circuit. This helps maintain proper oil levels and ensures minimal oil losses to the air system.

Why Maintenance Matters

  • Prevents excessive oil carryover into the compressed air system
  • Maintains correct oil return flow to the airend
  • Helps the separator element last longer and perform efficiently

Signs Your Scavenge Line Needs Attention

  • Increased oil consumption
  • Oil residue in downstream air lines or tools
  • Frequent topping off of oil levels
  • Reduced overall system efficiency

When to Inspect and Replace

Atlas Copco generally recommends inspecting the scavenge line every 4,000 hours or at major service intervals. Check for blockages, cracking, or hardening of hoses. Replace the line or associated kits (like scavenge line kits) as needed to maintain proper operation.

Keep Oil Where It Belongs

Regular scavenge line maintenance is an easy step to prevent expensive oil losses and keep your GA VSD+ compressor running clean and efficiently.
