Also specified as: Airtight Interlock Clean Room Door
A paired-door airlock system where electronic interlock logic prevents both leaves opening simultaneously — protecting the pressure cascade between clean and less-clean zones. Built to your room layout from prototype to full production runs.
An interlock door system is the physical enforcement of a GMP pressure cascade: only one leaf of the airlock can be open at any time, so unfiltered air never passes straight through.
The RAX Interlock Clean Room Door pairs two flush, gasket-sealed leaves (swing or sliding) with an electronic controller that locks one leaf while the other is in use. Status indicators (LED / buzzer) show which leaf is unlocked, and an emergency override releases both for evacuation. The logic accepts timer delays, access-control inputs and BMS dry contacts.
It is the standard solution for personnel and material airlocks between GMP grade boundaries, hospital sterile corridors, electronics clean zones and food production hygienic barriers.
GMP grade references (EU GMP Annex 1) and ISO 14644-1 classes are industry-standard designations used to position the airlock; 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.
| Parameter | Specification | Basis |
|---|---|---|
| Configuration | Paired leaves (swing or sliding) with electronic interlock controller. | RAX configuration |
| Interlock Logic | One-leaf-at-a-time; adjustable timer delay 0–60 s; emergency release. | RAX design |
| Status Indication | Per-leaf LED + buzzer; optional remote BMS dry contact. | RAX design |
| Leaf Material | Galvanized steel powder-coated, or stainless 304 / 316. | Per project |
| Sealing | Perimeter silicone / EPDM gasket; optional drop-bottom seal. | RAX design |
| Cleanroom Suitability | Airlocks referenced to ISO 14644-1 Class 5–8 / GMP grade B–D. | Industry standard reference |
| Power Supply | 220V / 24V DC interlock controller; UPS backup optional. | Per project |
| Standard Opening | 900 × 2100 mm per leaf; custom sizes on request. | Industry-typical |
| Cycle Life | 100,000 cycles validated in the RAX fatigue test lab. | RAX-measured |
Interlock wiring diagrams and controller settings ship with every system. Confirm leaf type (swing / sliding), access-control interface and emergency-release strategy 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.
GMP grade and ISO 14644-1 class are validated at facility level; the interlock system is supplied to enforce the pressure cascade, with logic-test documentation to support your qualification.
Large industrial doors from prototype to container-load delivery.
Configure leaf type, interlock logic, access-control interface, indicator style and emergency-release strategy per airlock. 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.
A controller monitors both leaves. When one leaf is opened, the opposing leaf’s electromagnetic lock engages and its indicator shows red. Only when the first leaf is fully closed and the timer delay expires does the second leaf unlock. An emergency override releases both leaves simultaneously for evacuation.
Yes. The controller accepts dry-contact inputs from card readers, biometric scanners or BMS. Wiring diagrams and interface specs ship with the door so your controls integrator can connect without custom engineering.
Fail-safe mag-locks release on power loss so personnel are never trapped. An optional UPS backup keeps the interlock active during short outages. The emergency break-glass release provides a manual override regardless of power state.
Yes. The interlock system works with swing leaves, sliding leaves, or a combination. Sliding interlock pairs are common in high-traffic corridors and automatic personnel airlocks.
Sample 7–15 days; standard container 12–20 days; custom first order 20–35 days, repeat orders 15–20 days. FOB Tianjin or Qingdao, FCL and LCL supported.
