Satair Group, PALL Aerospace and VietJet sign contract for avionics cooling filtration system

At the MRO Asia exhibition VietJet, Vietnam’s fast-growing low-cost carrier signed a five-year contract for the fitting of Pall Aerospace’s Avionics Cooling Filtration System on to its fleet of 92 Airbus A320 family (plus five options) aircraft that it operates and has on order. The deal is the largest ever Pall Aerospace Supplier Furnished Equipment (SFE) contract won by Satair Group in Vietnam and is valued at some US$1.4m. The Pall system was introduced to combat the issue of water ingress and dust build-up in the avionics compartment and uses a patented cyclone separator system to remove free water from the air intake. This provides 100 percent water separation efficiency even under the most adverse Airbus testing conditions. The water removal efficiency remains constant and is not affected by the pressure drop across the filter element.
The system gives enhanced dust protection in the avionics bay and maintenance cost savings due to the improved filtration, as well as lower inventory holdings since Pall’s system requires only one filter element compared to two in the original system.
