Cleanroom high-speed door: combining hygiene, airtightness and productivity

26 February 2026

In controlled environments such as grey rooms, operational efficiency should never come at the expense of hygiene or safety.

These transition zones, common in the pharmaceutical, food processing and cosmetics industries, demand a delicate balance between productivity, airtightness and cleanliness. It is precisely in these contexts that the high-speed industrial door proves its value — and where Maviflex brings its French expertise.

Grey rooms: balancing control and performance

A grey room serves as a strategic link between controlled environments and standard production areas. Less restrictive than an ISO 5 cleanroom but far more demanding than a conventional workshop, it must maintain specific cleanliness and pressure conditions, typically classified ISO 7 or ISO 8.

Each opening, each flow of air or personnel represents a potential risk. Keeping operations efficient while limiting cross-contamination is a daily challenge for production managers. A door left open just a few seconds too long can destabilize pressure levels or compromise air quality — highlighting the need for a perfectly controlled access solution.

Why standard doors are no longer enough

In environments with strict hygiene requirements, traditional swing or sectional doors simply don’t measure up. Too slow and too permeable, they allow air and particles to pass through — and often drive up energy costs. The turbulence they create disrupts laminar airflow and increases the risk of contamination with every passage.

In contrast, high-speed industrial doors are designed specifically for these demanding applications. Their automated operation and airtight construction ensure effective separation while maintaining smooth movement of goods and personnel.

Flexible high-speed doors: a driver of efficiency and compliance

A high-speed industrial door opens and closes within seconds. This time saving — often underestimated — transforms workflow and environmental control. By reducing exposure time between two zones, it minimizes air exchange, maintains overpressure, and stabilizes ambient temperature.

  • Ultra-fast opening: up to 2 m/s, reducing air turbulence.
  • Enhanced airtightness: reinforced side seals, durable flexible curtain, and consistent pressure retention.
  • Controlled overpressure: stable conditions between ISO 7 and ISO 8 zones, even during frequent use.
  • Guaranteed hygiene: smooth surfaces and materials compatible with disinfection protocols.

A properly installed high-speed door does more than streamline movement — it directly contributes to regulatory compliance and production reliability.

Maviclean®: the Maviflex high-speed door for controlled environments

Developed from Maviflex’s French engineering expertise, the Maviclean® has been specially designed for grey rooms, cleanrooms and controlled atmosphere areas. Built to combine hygiene, sealing performance and speed, it meets the strictest requirements of pharmaceutical, electronics and food industries.

  • Stainless steel or anodized aluminum frame, corrosion-resistant.
  • Smooth, antibacterial curtain with no visible screws for easy cleaning.
  • Reinforced side sealing ensuring stable pressure differentials.
  • Fast and silent operation, compatible with contactless systems.
  • Custom-made in France, tailored to your flow and cleaning requirements.

Thanks to its hygienic design, MAVICLEAN® eliminates retention areas and integrates seamlessly into environments where air cleanliness and workflow speed are essential.

Hygiene and safety

Maviflex high-speed doors feature the latest innovations in safety and automation. The SafeTouch and SafeTime systems provide reliable motion detection, allowing contactless operation and automatic closure once the passage is complete.

The result: no collision risks, no manual contact, and a safer environment for both operators and products. This seamless operation helps maintain pressure cascades and reduces the time required for air rebalancing within the room.

Productivity and long-term performance

Installing a Maviflex high-speed door in a grey room means investing in long-term reliability. Designed to handle several hundred thousand cycles per year, these doors require minimal maintenance and deliver a fast return on investment through energy savings and improved productivity.

Field feedback confirms that a properly sized high-speed door can reduce thermal losses by 20 to 30% while improving daily operational flow. A high-performance, durable solution — meeting the standards of the most sensitive environments.
