Abstract

An apparatus for filling product into containers includes a working chamber through which the containers pass and the containers are acted upon by a sterile fluid to avoid contamination. An external line extends through the working chamber having a plurality of gas openings for the introduction of sterile air into the working chamber and that an internal line extends into the external line having a plurality of openings for spraying a cleaning medium. An annular chamber extends in a longitudinal direction between the internal and the external line. The cross-sectional area of the annular chamber varies in the longitudinal direction so that an even distribution of sterile air emerging from the gas openings into the working chamber is achieved.
