A pressure swing adsorption apparatus (10) is provided with actuator air via a reservoir (40) which draws its supply either from one or more of the process vessels (12) after it has been dried thereby or directly from the system compressor (32). Controls are provided to ensure actuator air is preferentially drawn from the dried source and for ensuring instrument air is available even on start up of the apparatus.
