The Advantages of Ventilated Hatches are Many....

The hatch air is “cleaned” following use to either the filtered air level of the supply or the higher classification room.

Less risk of lower classification air entering the higher classification room.

Electrically controlled interlocks are available to ensure hatch “air” is given time to recover before the other door can be opened.

Facilitating the quick transfer of goods between different grades of rooms
