Clean Bench
Vertical Laminar-Flow Local Clean Environment

The QM2100 clean bench uses vertical laminar airflow; a HEPA filter continuously recirculates and purifies air to form a unidirectional clean air curtain in the work zone. A UV sterilization lamp sterilizes the chamber outside working hours. It suits electronic-component assembly, microbial inoculation, precision-instrument inspection, drug dispensing and other operations requiring localized cleanliness.

From chip packaging to sterile inoculation - high-precision operations need a localized dust-free environment; vertical laminar flow forms a unidirectional clean air curtain that blocks outside contamination. HEPA filtration plus UV sterilization ensures cleanliness, and the wide-view window eases observation.

Designed for localized clean operation - vertical laminar flow plus HEPA filtration, a Class-100 clean bench.

  • ▪HEPA filtration · Class-100 cleanliness
  • ▪UV sterilization lamp · off-hours sterilization
  • ▪Adjustable airflow + independent control · flexible
