Auxiliary Power Units

We have installed over 6,500 PBS auxiliary power units (APU).

Application of auxiliary power units

Use of APUs in Civil and Military Helicopters

Our SAFIR auxiliary power units can be primarily seen in several developed versions and modifications. The achieved parameters of these units enabling simultaneous supply of compressed air and electricity, an operating altitude up to 6,000 m, continuous operation for up to 6 hours, and a service life of 4,500 hours, ranks PBS APUs in the category up to 100 kW among the world's best. 

For more information about our APUs, please contact our experts.

Trainer Aircraft Use PBS APUs

SAFIR auxiliary power units from PBS have so far also been applied in trainer and light combat aircraft. The quality of our products, flexible service and high level of customer service are reassurance of further cooperation with our long-standing customers and users on next-generation aircraft. Our APUs are used in L-159 ALCA, L-39 Albatros.

Service, spare parts and overhauls of aerospace technology

We provide service of the highest quality for all users of our aerospace technology products.

We have long been working to extend the service life of our products, e.g. by introducing new technologies to produce the most exposed parts. Our turbine-based aircraft equipment regularly receives very good references.
