Construction of a Prefabricated Modular Building for a Thermal Disinfection and Decontamination Station for Pathogenicity Groups III–IV Effluents

To provide a complete vertical integration for cleanroom construction, the INEX Design Bureau has engineered a new model of an Active Air Pass-Through Hatch. These airlocks are critical for maintaining differential pressure and sterility standards when transferring components between zones of different cleanliness classes or varying biological hazard levels.

Technical Configuration & Components: The INEX innovative airlock integrates precision-engineered mechanical and electronic systems:

• Filtration: Two-stage system featuring a G4 pre-filter and a high-efficiency H14 HEPA filter.

• Safety & Access: Electro-mechanical interlocking (EMI) system with one-way access logic and an emergency override button.

• Timing Logic: Programmable door-lock timers to ensure full decontamination cycles.

• Aerodynamics: Integrated diffusers for optimized airflow distribution.

• Aesthetics: High-durability finish in RAL 9003 (Signal White).

Operating Principle & Contamination Control: The design prevents the simultaneous opening of both doors, maintaining a physical barrier between environments. To meet ISO 14644-1-2017 standards, the hatch employs an active scavenging (purge) cycle. When materials are placed inside, the internal chamber is flooded with HEPA-filtered air to remove surface particulates before the opposite door is released.

Structural Superiority:

• Dual-Shell Protection: The unit features a dual-layer design—an outer casing and an inner chamber—providing double protection against air leakage and external particle infiltration.

• Universal Integration: The frame is engineered to be seamlessly integrated into partition walls of any material (Sandwich panels, HPL, or masonry).

• Aseptic Integrity: All internal corners and surfaces are designed for easy disinfection, eliminating microbial growth niches.

This proprietary development strengthens INEX’s position in the import substitution market, offering our clients a high-tech, reliable alternative to international brands without compromising on budget or technological safety.
