SAFIR 5L

The SAFIR 5L is a compact auxiliary power unit designed to supply compressed air to aircraft engine starting systems. Its lightweight and space-saving design enables reliable engine starts even under demanding environmental and altitude conditions.

The unit is optimized for use in modern trainer, multirole, and unmanned aircraft. With its high performance, low weight, and minimal installation space requirements, the SAFIR 5L is ideal for integration into limited fuselage compartments.

The APU is equipped with an advanced automatic control system ensuring operational safety, fault indication, and digital communication with the aircraft systems. The cleanliness of the bleed air also allows its use for onboard environmental control systems.
