VEH21866 PIPE/BREATHER GE160/200--N/F

Gas turbine engine oil systems ingest air in the bearing cavities, and thus a breather (also known as an air-oil separator) is provided to remove air from the oil.

The breather is vented to allow the air to escape.

• any accumulation of carbon and oil sludge that could cause obstructions in the pipe
• soft connecting elbows (these could bend and obstruct the gas flow)
• soft rubber pipes (these could cause vacuum leakage at the connection point)
