Safir 5K/G MIS is an auxiliary power unit designed to deliver compressed air for starting the main engines, and to supply DC to the deck network.
The Safir 5K/G MIS is one of PBS's most reliable Auxiliary Power Units and one of the most competitive APUs on the market. This is thanks to several favorable factors in the designing and production of this unit. The Safir 5K/G MIS distinguishes itself from our other APUs because it is the only one to supply DC voltage to the aircraft’s on-board network.
The compressed air can be used for the environmental control system. The auxiliary power unit contains all the necessary accessories for safe operation and momentary as well as long-term diagnostics of the unit. The exhaust gas temperature, revolutions and other indicators are constantly monitored. The fuel and oil filter status is also signalled. All data are recorded by the control unit equipped with a RS 422 communication interface.
This APU was certified for civil aviation
by AR MAK according to AP-VD, and by EASA.
