• Enclosure: 304/316 stainless steel, corrosion-resistant and easy to clean.
  • Double-door interlock: Mechanical interlock (purely mechanical, reliable) or electronic interlock (electromagnetic lock + indicator light, intelligent); the two doors can never be opened simultaneously.
  • Sealing: EVA gaskets, ensuring a tight, leak-proof seal.
  • Sterilisation: Built-in UV lamp (optional), for eliminating surface microorganisms.
  • Self-cleaning (high-end): HEPA filter + fan, providing self-cleaning, air shower and laminar flow functions.

Common Types

  • Standard interlocking type: Interlocking and sealing only, suitable for general clean areas (food, packaging).
  • Self-cleaning (Air Shower): High-speed clean air shower sweeps over material surfaces, suitable for electronics and semiconductors.
  • Laminar Flow Pass-through: Upward supply and downward return laminar flow, achieving Class 100 cleanliness internally, suitable for pharmaceutical and sterile laboratories.

Workflow (Standard)

Open outer door → Place materials → Close door → UV sterilisation/self-cleaning (optional).
Open inner door → Retrieve materials → Close door.
Both doors remain closed simultaneously throughout the process to prevent cross-contamination.

Applications

  • Pharmaceutical plants, hospital operating theatres, biological laboratories
  • Electronics factories (semiconductors, LCDs), precision manufacturing
  • Food processing, cosmetics, new energy workshops

Selection Criteria

  • Interlock type: Mechanical (cost-effective and durable) / Electronic (intelligent).
  • Cleanliness grade: Standard (Class 10,000) / Air shower (Class 1,000) / Laminar flow (Class 100).
  • Dimensions: Customised to material size; common dimensions are 600 × 600 × 600 mm.
  • Material: 304 (standard) / 316 (corrosion-resistant).

Operation and Maintenance

  • Routine: Clean the interior walls after each shift; regularly inspect the seals and interlock functions.
  • UV lamp: Replace after 500 cumulative hours of use to ensure effective sterilisation.
  • Filters: Replace when the pressure differential exceeds the specified limit (typically every 6–12 months).
