Powder locks

Powder locks and/or double flap locks ensure that when filling containers, there is no direct contact between the container interiors of the unit to be charged and the surrounding environment. They also prevent hazardous substances from escaping.
VOLKMANN powder locks can be easily purged with an inert gas (for example Nitrogen) so that no unwanted atmosphere (Oxygen) passes from the lock into the receiving vessel. With the powder lock, it is also possible to avoid unwanted receiving vessel gases passing back through to the conveying process.
