Epiroc 3115294500 Ventilator Breather – Made for COP 3060, 2560, and 2550 Series Drifters

The 3115294500 ventilator breather is a factory-spec replacement part for a range of Epiroc COP drifters. Its job is straightforward: let the gearbox breathe while stopping dust, water, and slurry from working their way inside. Threads in directly where the old breather came out—no adapters, no drilling.

This part fits the following models:

  • COP 1850 / 1850CR
  • COP 2160
  • COP 2550 / 2550+
  • COP 2560 / 2560+
  • COP 3060

If you've noticed a buildup of internal pressure or oil mist around the back head, this is often the first part worth checking.

Highlights
Key Advantages
  • OEM vent breather, machined to Epiroc’s tolerances—no sealing issues from day one.
  • Threads match the back head on COP 1850 through 3060, so you can swap it in under 10 minutes.
  • Internal sintered element blocks dust and moisture in wet drilling, without choking airflow.
  • Overheating is tough on seals and O-rings; a clear breather helps pressure equalize fast during the percussion cycle.
Use Cases
Applications
  • Underground production drilling with COP 2550/2560 drifters
  • Tunnelling jumbos running COP 2160 or 3060
  • Surface bench drilling where dust and rain are a constant challenge
  • Raise boring and slot hole setups using high-output COP models
  • Rebuilds and component swaps for older Atlas Copco hydraulic drills

FAQ
FAQ
Do I need any special tools to install the 3115294500 breather?
No. It threads in by hand first, then a light snug with a wrench. Just make sure the drifter is off and the back head isn’t under pressure before you start.
How do I know if my current breather is blocked or failed?
Common signs are oil mist around the back head, a whistling noise from trapped pressure, or the drifter running hotter than usual. Unscrew it and see if the airflow is restricted.
Will this fit my older Atlas Copco COP 1838 or 1238?
It’s not listed as a direct match. We recommend cross-referencing with your serial number or checking the parts book for your specific model first.
Is there a recommended service interval for replacing breathers?
No factory-set interval, but many crews replace it when doing a seal kit change or every 2,000–3,000 rod meters if they’re in wet or gritty conditions.
What material is the breather made from?
The body is steel with a corrosion-resistant coating. The internal element is sintered bronze, designed to pass air but block fine particles.
