The Centrisep® Engine Advanced Protection System (EAPS) separates water from the main engine airflow. Any remaining water that does enter the engine inlet is in the form of a harmless spray, which has no significant detrimental effect whatsoever on engine operation.
Although a Centrisep EAPS will greatly alleviate the hazard created by heavy rain, the helicopter’s flight manual instructions must strictly be adhered to at all times.
