An aircraft installation (1) of a pneumatic system of an aircraft with different compressed air sources for supplying pressurized air to an air consumer equipment (6) comprises a gas turbine engine having a single port (2.1) located at a low-intermediate compressor stage of the gas turbine engine, a bleed duct (2) with one end in fluid communication with the single port and an opposite end (2.2) in fluid communication with the air consumer equipment, a cooling duct (3) comprising an inlet (3.1) by which cooling air enters into the cooling duct, a branch duct (4) in fluid communication with the bleed duct and the outlet (3.2) of the cooling duct for diverting a portion of the bleed air from the bleed duct into the outlet of the cooling duct, an electrical compressor (5) with an intake (5.1) in fluid communication with the outlet of the cooling duct after the joining with the branch duct and an outlet (5.2) in fluid communication with the opposite end of the bleed duct, such that each of the bleed system or the electrical compressor or a combination thereof may perform such supplying of compressed air depending on the aircraft operation condition, for instance the flight altitude or specific flight phases. Also, a turbofan engine (7) and a method for supplying compressed air to air consumer equipment are provided.
