The "Gas-Generator Module" belongs to the A380.
But compressed gas in a bottle
is common and usual.
I checked the AMM from A320, A300, A310, A330, A340, B737 Fam, B747 Fam (incl.-800), B757, B767, B777, MD11.
They all use also only compressed gas (without "Gas-Generator Module").
I am not sure about the system in the B787.
