Cleanroom Air-tight Doors
Cleanroom Air-tight Doors: Controlled Access for High-Containment Zones
In the delicate balance of a microbiology lab or pharmaceutical suite, maintaining precise pressure differentials is the only way to ensure safety and sterility. Metrolabs provides Cleanroom Air-tight Doors, engineered to prevent the uncontrolled exchange of air and particulates between different classes of cleanrooms.
Our air-tight systems are a critical structural component for facilities that require high-accuracy containment and absolute environmental stability.
Engineered for Pressure Control
The primary function of an air-tight door is to support your facility’s HVAC system by creating a reliable seal. Whether you are maintaining positive pressure to keep contaminants out or negative pressure to keep hazardous pathogens in, our doors provide the necessary resistance.
Advanced Gasket Technology
We utilize specialized, non-aging EPDM or medical-grade silicone gaskets. Unlike standard seals, these are designed to: Maintain Elasticity: Resist permanent deformation even after thousands of cycles. Resist Sterilants: Withstand frequent exposure to Vaporized Hydrogen Peroxide (VHP) and high-concentration disinfectants. Compress Effectively: Create a continuous, leak-proof barrier against the door frame.
Seamless, Flush Construction
Consistent with our "Zero-Ledge" philosophy, our air-tight doors integrate perfectly with our Modular Cleanroom Panels. Flush Frames: Designed to be installed level with the wall surface. Non-Shedding Materials: Stainless Steel or high-grade powder-coated finishes that do not release particles into the airflow.
Specialized Internal Core
To ensure the door leaf itself does not bow or warp under pressure, we use high-density, rigid cores such as: Aluminum Honeycomb: Offering maximum flatness and structural integrity. PUF (Polyurethane Foam): For superior thermal insulation and sound dampening.
Performance Features
| Feature | Metrolabs Air-tight Standards | Benefit |
| Leakage Class | Tested for high-pressure resistance | Prevents “whistling” and pressure loss. |
| Drop Seal | Automatic mechanical bottom seal | Seals the floor gap without a protruding threshold. |
| Interlocking | Compatible with PLC-based logic | Ensures air-lock integrity during entry/exit. |
| Vision Panels | Integrated flush double-glazing | Safety monitoring without compromising the seal. |
Strategic Applications
Metrolabs Air-tight Doors are the preferred choice for environments where atmospheric failure is not an option:
Biotechnology Labs (BSL-2/3/4): Preventing the escape of infectious agents.
Pharmaceutical Filling Lines: Protecting sterile products from external microbes.
Operating Theaters: Maintaining a positive pressure “bubble” around the patient.
Electronic Cleanrooms: Eliminating the ingress of micro-particles.
The Metrolabs Advantage
At Metrolabs, we design for long-term performance. We understand that an air-tight door is a dynamic part of your infrastructure. Our installation team ensures that every frame is perfectly plumb and every seal is verified, providing a high-accuracy solution that supports your facility’s compliance for years to come.
Technical Note: All our air-tight doors can be customized with hands-free automation, ensuring that your staff can move through high-containment zones without touching handles, further reducing the risk of cross-contamination.
