CGTM, a subsidiary of  Turbomeca, has announced the issuance by Transport Canada and the FAA of a Supplemental Type Certificate for the installation of the optional air particle separator QB 0777 on all AS350 type helicopters. The arrival of this new Vortex particle separator on the market marks a technological breakthrough compared to old-generation sand filters. Developed in partnership with the Pall Aerospace company, it protects the Arriel turboshaft engine air inlet against the ingestion of airborne particles. 

Performance tests carried out in hostile environments (the Sahara Desert) showed the efficiency of the filtration sys- tem, compared to the sand filter, improved by a factor of 10, surpassing 95%, without the inconveniences of barrier filter technologies.  This equipment is also of interest to customers carrying out lime spreading to treat forests and lakes damaged by acid rain. It significantly reduces the risks of turbine erosion and consequently the need for maintenance operations, thereby improving helicopter availability. The filter also provides protection against snow.
