Sand Filter for Arriel 2D™ Engine
SB number : EC130-71-60-03 (R01)
Applicable to version(s) : T2
This equipment, mandatory for flights under snowfall, is also used to filter efficiently sand or dust particles and provides a good ice protection. It protects the engine from the ingestion of sand. It therefore prevents the premature wear of the compressor blades due to the ingestion of sand and other contaminants. In addition, the Sand filter installation also protect the air intake against the potential induction of flying particles.
Filtering reduces ingress of sand and dust, what enables to reduce premature engine ageing due to erosion. This installation also protects from absorption of sand and snow. Flights are prohibited under snowfall without the sand filter installed. The sand filter does not result in any loss of performance.
