Interlock Clean Room Door — RAX Door Technology
01 · Overview

Airlock Protection for Clean Rooms

Interlock clean room doors are designed for airlock systems where two doors cannot open simultaneously. This prevents direct air exchange between clean and non-clean zones, maintaining clean room classification and preventing contamination ingress. Unlike standard doors that operate independently, interlock doors feature electronic control systems that coordinate door operation.

RAX manufactures interlock clean room doors with stainless steel SS304/SS316 panels, multi-layer EPDM sealing systems, and servo motor drive with interlock control. Opening speeds up to 1 m/s minimize exposure time during each opening cycle. Airtight sealing maintains positive pressure differentials.

These doors are essential for pharmaceutical clean rooms, biotechnology laboratories, semiconductor manufacturing facilities, hospital isolation rooms, and any environment where airlock protection is required.

02 · Key Features

Engineered for Airlock Systems

Electronic Interlock Control

Two doors cannot open simultaneously. Electronic control system coordinates door operation. Prevents direct air exchange between clean and non-clean zones. Maintains clean room classification.

Stainless Steel Construction

SS304/SS316 stainless steel panels resist bacterial growth and are easy to clean and sanitize. Non-porous surfaces prevent contamination accumulation. Suitable for washdown environments.

Multi-Layer Airtight Sealing

Multiple EPDM seals on all four sides create airtight barrier. Perimeter seals, inter-panel seals, and bottom seals work together to prevent air exchange. Maintains positive pressure differentials.

High-Speed Operation

Opening speeds up to 1 m/s with servo motor drive. Frequency converter for smooth acceleration/deceleration. Minimizes exposure time during each opening cycle.

Positive Pressure Maintenance

Fast operation + airtight sealing maintains positive pressure in clean rooms. Critical for preventing contamination ingress. Supports ISO 14644 clean room classification.

Smart Control

PLC-based interlock control with LCD display. Integration with clean room monitoring systems. Remote operation and diagnostics. Programmable speeds and delay times.

04 · Applications

Where Interlock Doors Excel

Pharmaceutical Clean Rooms

GMP-compliant environments require airlock protection. Interlock doors prevent direct air exchange between zones. Airtight sealing maintains positive pressure. Fast operation minimizes exposure time.

Biotechnology Laboratories

BSL-2 and BSL-3 laboratories require strict containment. Interlock doors prevent pathogen escape. Smooth surfaces easy to decontaminate. Fast operation supports workflow efficiency.

Semiconductor Manufacturing

Clean room environments for chip manufacturing. Interlock doors prevent particle ingress. Smooth surfaces minimize particle generation. Fast operation supports production throughput.

Hospital Isolation Rooms

Negative pressure isolation rooms require airlock protection. Interlock doors prevent pathogen spread. Smooth surfaces easy to disinfect. Fast operation supports emergency access.

Food Processing Facilities

HACCP-compliant environments require contamination control. Interlock doors prevent cross-contamination between zones. Smooth surfaces resist bacterial growth.

Research Laboratories

University and industrial research labs with clean room requirements. Interlock doors maintain clean room classification. Fast operation supports research workflow.

05 · Customization

OEM / ODM & Customization

RAX supports full private-label production of the Interlock Clean Room Door: custom panel material (SS304/SS316), sealing configuration, interlock control programming, motor specification, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds and tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.

06 · Compliance

Applicable Standards

EN 13241:2003+A2:2016

Core CE product standard for industrial, commercial, and garage doors. Covers both manual and powered doors. Requires Declaration of Performance (DoP) under CPR 305/2011.

EN 12453:2001

Safety requirements for powered doors. Specifies force limiting, safety devices, and control system requirements.

ISO 14644

Clean room classification standard. Interlock doors support clean room classification by maintaining positive pressure and preventing contamination ingress.

CE Marking

Mandatory for export to EU/UK markets. RAX provides CE technical file and Declaration of Performance with every shipment.

How does interlock control work?

Electronic interlock system ensures two doors cannot open simultaneously. When one door opens, the other door is locked. Prevents direct air exchange between clean and non-clean zones.

Are interlock doors suitable for clean rooms?

Yes. Smooth stainless steel panels, multi-layer sealing maintains positive pressure. Interlock control prevents contamination ingress. Supports ISO 14644 clean room classification.

What is the opening speed?

Up to 1 m/s opening speed, 0.8 m/s closing speed. Speed is adjustable via PLC control system. Servo motor with frequency converter ensures smooth operation.

Can interlock doors integrate with clean room monitoring?

Yes. PLC-based interlock control integrates with clean room monitoring systems. Remote operation and diagnostics available. Programmable speeds and delay times.

Do you provide installation?

No — RAX is a pure manufacturer. Doors ship with English installation manuals, wiring diagrams, and remote support.

What is the lead time and warranty?

Standard configurations: 12–20 days. Custom first order: 20–35 days. Repeat orders: 15–20 days. Warranty: panels 10 years, motor and control 5 years.
