C919 Fuel tank inner filter 1

Porvair Filtration Group will be showcasing its fuel tank inerting filter technology at this year’s Paris Air Show (23rd - 25th June), demonstrating why this component is now part of the largest commercial passenger aircraft to ever be built in China. 

Porvair supplied a filter to the fuel tank inerting system (FTIS) produced by Parker Aerospace, which has just celebrated the first flight of the new COMAC C919 in Shanghai. The narrow-body twinjet airliner is China’s first large passenger jet, and Porvair is proud that its inerting filter has been integrated into the design.

Inerting system

Lightweight, on-board aircraft fuel tank inerting systems can be fitted within existing aircraft designs. The company has developed a range of filter systems that ensure the source of engine bleed air is free from both particulate and liquid contamination, protecting the sensitive air separation modules and ensuring long service life testing.

The Parker Aerospace system floods the fuel tank ullage space with an inert gas stream, which aims to reduces oxygen concentration, thus improving safety. Porvair will be exhibiting at Paris Air Show, Hall 6 Stand A53, from 19-25 June.
