The Rewards of Ventilated Hatches are Many....

PBSC’s hatches are designed to aid the reduction of cross-contamination and pressure loss whilst passing products between lower and high classification areas. The 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, easing quick transfer of goods between different grades of rooms.

PBSC's Trolley Hatch can also be known as a Trolley Transfer Hatch, Pass Box, Pass Thorough, Through Box, Cleanroom Transfer Hatch, Cleanroom Hatch, Pass-Thru, Hospital Box and a Lab Box.
