When selecting high-speed doors for clean rooms or food factories, air tightness, cleanability, corrosion resistance, and microbial control are critical. This article breaks down key standards including ISO 14644-1, FDA, and EHEDG to help you make compliant, safe, and efficient choices.
In clean rooms or food factories, high-speed doors are not just partition devices - they are critical points for contamination control. A door that fails to meet industry standards can become a collection point for dust, microorganisms, or condensation, seriously affecting product quality and production safety. Therefore, strict adherence to relevant standards is essential.
Clean rooms are typically classified according to ISO 14644-1 for airborne particle concentration (e.g., ISO 5, ISO 6, ISO 7, ISO 8). High-speed doors should have the following features:
High air tightness – sealing strips between the frame and curtain to minimize particle infiltration.
Low-friction operation – to prevent micro-particle generation from wear.
Smooth, seamless surfaces – for easy cleaning and to avoid dust accumulation.
Food factories place greater emphasis on food contact safety and microbial control. Key standards include:
FDA (U.S. Food and Drug Administration) – door materials (e.g., PVC, stainless steel) must comply with FDA 21 CFR requirements: non-toxic, non-migrating, and corrosion-resistant.
EHEDG (European Hygienic Engineering & Design Group) – focuses on hygienic design, requiring no dead corners, no exposed threads, and fully cleanable surfaces.
Antimicrobial treatment – the curtain material should contain antimicrobial agents or surface treatments to prevent bacterial growth.
In addition to cleanliness and hygiene standards, high-speed doors may also need to meet:
EN 12426 (Air permeability) – ensuring controlled leakage under pressure differences.
EN 16361 (High-speed door safety) – including impact recovery, light curtains or sensor protection.
Anti-condensation design – in refrigerated/frozen food areas, door surfaces should avoid condensation to prevent mold growth.
When selecting high-speed doors for clean rooms or food factories, check the following items:
| Item | Clean Room Requirement | Food Factory Requirement |
|---|---|---|
| Material compliance | ISO 14644 compatible | FDA / EU 10/2011 |
| Surface finish | ≤0.8µm Ra | ≤0.8µm Ra, hygienic grade |
| Air tightness | High (EN 12426 class 3/4) | High (class 3/4) |
| Cleanability | Yes | Yes (EHEDG certified preferred) |
| Antimicrobial | Optional | Highly recommended |
| Anti-condensation | Optional |
Mandatory in cold storage areas |
When selecting high-speed doors, don't focus only on speed and price - ensure they meet the core standards for clean rooms or food factories. From ISO 14644 to FDA and EHEDG, compliance is the foundation for safety, efficiency, and passing audits. We recommend working closely with a supplier experienced in industry certifications and requesting third-party test reports or compliance declarations.
