Laminar Flow and Containment Equipment
Rapid Transfer Port
A fixed circular barrier port that docks with a compatible container or bag interface so both doors can open together without exposing their contaminated outer faces.
- Double-Door Transfer Principle
- Interlocked Circular Docking
- Fixed Barrier Alpha Port
- Multiple Useful Diameters
Product Introduction
The rapid transfer port mounts to an isolator, RABS or cleanroom wall and forms the fixed half of a double-door transfer system. A compatible removable container or bag port docks by guided rotation or another secure lock. The two doors couple so their exposed faces remain closed together while the combined opening provides access through the barrier. Mechanical interlocks prevent the fixed door from opening without a correctly connected counterpart and prevent undocking while the doors are open.
Key Features
Mechanical interlocks enforce the correct dock-open-close-undock sequence.
Coupled doors isolate their previously exposed surfaces during transfer.
Replaceable lip seals maintain the connection around the selected port size.
Multiple diameters accommodate small components, tools, bags or containers.
Customer Product Concerns
A barrier port must prevent incorrect opening and keep the two exposed door faces isolated throughout connection and disconnection.
The barrier door can open without a transfer container.A mechanical interlock blocks the fixed door until the compatible port is fully docked.
The container is removed while the door remains open.The locking sequence prevents undocking until both door halves are closed.
Misalignment damages the seal during connection.Guide features and a defined rotational lock center the two circular interfaces.
One port size is unsuitable for both tools and bulk components.A family of useful diameters supports different transfer loads.
Typical Applications
Isolator material transferRABS component loadingSterile tool transferContained waste removal
