The EFAFLEX EX series is designed for industrial environments where explosive atmospheres may be present, including chemical processing facilities, refineries, and sites handling flammable gases, vapours, or dusts. Suitable for both interior and exterior applications, these doors provide reliable operation and safety in areas requiring strict compliance with ATEX zones 1, 2, 21, and 22.

With high-speed opening and closing, the EX series supports efficient workflows while helping to contain hazardous substances and maintain environmental separation. The doors are engineered for integration with building automation and safety systems, ensuring controlled access and regulatory compliance in hazardous zones.

Built for high-traffic applications, they facilitate the safe movement of personnel and materials. Available in a range of sizes and finishes, including corrosion-resistant options, the EX series can be adapted to meet specific site and operational requirements.

• Suitable for use only in ATEX-certified zones; control panels must be installed outside the hazardous area.
• Operating temperature range is -15°C to +50°C; stainless steel finishes are recommended for high-corrosion or marine environments.
• Requires stable mounting surfaces; integration with automation systems must use ATEX-compliant components.
