Abstract

An apparatus for molding plastic preforms into plastic containers, includes a clean room, at least one blow station having a blow mold for shaping the plastic preforms by at least one process pressure, and a venting device for venting or reducing the process pressure into the atmosphere. The venting device has at least one venting valve through which pressure can be vented into the atmosphere via a sound absorber, and a pressure drop safety device for closing the venting valve before the atmospheric pressure level on the venting device is reached.
