Working Principle
The automatic self cleaning pass box manufacturers features a built-in independent air circulation system. Before each access control operation, the system automatically activates high-speed circulation:
An EC centrifugal fan generates a high-speed airflow of 18–22 m/s.
The airflow passes through H13/H14-grade HEPA high-efficiency filters.
Filtration efficiency is 99.97%–99.995% @ 0.3 μm.
This produces a unidirectional clean airflow that quickly sweeps away suspended particles inside the chamber.
It restores the chamber to a clean state within 30–45 seconds.
The particulate removal rate exceeds 99%, and the internal cleanliness level reaches ISO Class 5 (Class 100).

SYNRUI Case Analysis
Case 1: Biopharmaceutical Cleanroom
Eight sets of automatic self cleaning pass boxes suppliers were provided to a biopharmaceutical plant. Equipped with H14 HEPA filters, these windows feature a self-cleaning airflow velocity of 20 m/s and can restore cleanliness to the original level in just 30 seconds. This GMP-certified equipment significantly reduces the risk of bacterial and particulate contamination during material transfer.
Case 2: Food Packaging Workshop Upgrade
Faced with high dust levels and strict hygiene requirements, a food company opted for SYNRUI customized automatic self cleaning pass boxes to replace traditional windows. The automatic cleaning cycle is 35 seconds, and the seamless internal structure facilitates easy wiping, reducing manual cleaning time by 30% and resulting in more stable overall hygiene control.
Case 3: Semiconductor Clean Production Line Expansion
A semiconductor plant purchased 20 sets of the equipment at once, requiring standardized specifications and rapid installation. SYNRUI's modular design improved on-site installation efficiency by 50%, and the equipment achieves ISO 5 cleanliness standards, meeting the sensitive production requirements of electronic components.
Case 4: Drug Delivery System in a Top-Tier Hospital
