Application of auxiliary power units

Civil and military helicopters

Our SAFIR auxiliary power units can be primarily seen in Russian and Chinese helicopters 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. Existing versions of APU Safir are used in Mi 8, Mi 17, and Z8 helicopters.

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

Trainer and light combat aircrafts  

SAFIR auxiliary power units from PBS have so far also been applied in trainer and light combat aircrafts. 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 aircrafts. Our APUs are used in L-159 ALCA, L-39 Albatros and L-15.
