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.
