1. An apparatus for treating plastic preforms, said apparatus having a transport device which has a circulating carrier configured to transport the plastic preforms along a predetermined transport path, a first application device configured to act upon the plastic preforms with a first flowable medium through a mouth of the plastic preforms during transport of the plastic preforms along a first section of the transport path, and a second application device configured to act upon the plastic preforms with a second flowable medium during transport of the plastic preforms along a second section of the transport path through the mouth of the plastic preforms, wherein at least one of said first or said second application devices has an ionising device for ionising air, so that the first or second flowable medium is ionised air, wherein said first and said second application devices comprise an application element configured to introduce the first flowable medium and the second flowable medium into the plastic preforms, and wherein said first application device and said second application device are configured to use the application element to act upon the plastic preforms with the first flowable medium and the second flowable medium,
further comprising a suction device configured for sucking off air or a substance containing contaminants out of the plastic preforms, wherein the application of the first flowable medium and the suction with regard to a specific one of the plastic preforms take place at the same time, and
further comprising a switching device configured to switch over from acting upon the plastic preforms with the first flowable medium to acting upon the plastic preforms with the second flowable medium.
