Also specified as: Hermetic Hinged Door, Airtight Swing Door
A hinged door with a compression or drop-seal mechanism that achieves air-tight closure — ideal where a sliding header is impractical and a swing leaf with true pressure integrity is required.
Where ceiling space is limited or a sliding pocket cannot be built into the wall, a hermetic swing door delivers the same pressure integrity in a compact hinged format.
The RAX Hermetic Swing Door uses a cam-hinge or drop-seal mechanism: as the leaf closes, eccentric hinges or an automatic bottom drop-seal compress the perimeter silicone gasket against the frame. This creates a 4-side air-tight barrier without the overhead track depth a sliding door requires.
Available as a manual push/pull leaf with a door closer, or paired with an automatic swing operator for hands-free use, it suits hospital wards, pharma suite boundaries, laboratory containment and any pressure-rated opening where a swing format is preferred.
Cleanroom class references (ISO 14644-1) and hospital pressure requirements are industry-standard designations; they are not certificates held by RAX. RAX company facts are from the approved brand brief.
Every door is engineered to your opening. The values below are the validated baseline; final figures are confirmed on your specification.

Drop-seal actuation is automatic on close and retracts on open to prevent floor drag. Confirm hinge handedness, closer force and seal type on the technical layout.
Validated substrates, processed in-house on an auto PU foam panel line and CNC punching/bending centre.
Match the door to the opening duty — keep each card to one line.
Your installers get the full document set before the door ships.
Certificates we hold today, and the project-specific test data we arrange against the matching standard.
Hermetic performance is validated on-site after installation; RAX provides the door-set and compression-test documentation to support your IQ/OQ qualification.
Large industrial doors from prototype to container-load delivery.
Configure leaf material, hinge type, drop-seal, operator and hardware per opening. Full OEM/ODM under NDA.
From custom engineering to container-load delivery — the document set your local installers need.
Door body 2-year warranty; operator/motor 3 years (servo 5 years). Free spare parts within warranty, dispatched DHL/FedEx 5–7 days.
Eccentric cam hinges pull the leaf into the frame as it closes, compressing the head and jamb gaskets. Simultaneously, an automatic drop-bottom seal lowers to seal the threshold. The combined 4-side compression creates an air-tight barrier comparable to a hermetic slider.
No. The drop seal retracts automatically when the leaf opens and only descends when the leaf reaches the fully closed position. This prevents floor wear and ensures smooth manual operation.
Yes. A swing-door operator with radar or push-button activation provides hands-free use. The operator integrates with access control and BMS, and wiring diagrams ship with the door.
The compression seal is designed for typical differentials of 10–50 Pa. Achieved leakage depends on frame installation tolerance; we confirm the target on your technical layout and provide compression-test documentation.
