Material decontamination air lock for external sterilization of large dyestuff preparation tanks with peracetic acid. Connection to an external decontamination system and connection to the on-site ventilation system.

Material gasification air locks provide for sterile injection into clean rooms, for example, of filled dyestuff preparation tanks to be externally sterilized. The tanks are gasified in the lock with peracetic acid or hydrogen Peroxide. Due to the integrated LF recirculation air system, sterility is ensured also after the gasifying process. In Order to reduce the sterilisation cycle, the material decontamination air lock can be connected to the on-site ventilation equipment to flush the locks after gasification using supply and exhaust air.
