We specialize in the design and installation of Inflated Seal Doors—a critical solution for high-containment areas where airtight sealing and controlled environments are essential. These doors are engineered to provide a superior sealing mechanism that inflates a built-in gasket to achieve a hermetic seal, preventing any air leakage between adjoining spaces.
Widely used in Biosafety Level (BSL) laboratories, cleanrooms, pharmaceutical facilities, isolation wards, and containment zones, inflated seal doors help maintain pressure differentials and protect against contamination, airborne pathogens, or hazardous substances. With their robust design, they support compliance with strict biosafety and cleanroom protocols, ensuring environmental control and safety at all times.
Features
Inflatable Gasket Seal: When activated, the door’s periphery gasket inflates to press firmly against the frame, creating a complete airtight seal.
SS 304/316 or Powder-Coated MS Construction: Corrosion-resistant, hygienic, and easy-to-clean surfaces.
Automatic or Manual Inflation: Controlled via push-button, sensor, or integration with access control systems.
Interlock Capability: Can be synchronized with other doors or airlocks to prevent simultaneous opening and maintain pressure zoning.
Visual & Audible Indicators: Status lights and alarms for inflation, door position, and interlock control.
Flush Design: Seamless integration with cleanroom or lab walls for maximum hygiene and minimum air turbulence.
Custom Sizes Available: Tailored configurations for personnel or equipment entry.
