‌Dust-free Workbench‌
A dust-free workbench, also known as a Class 100 clean bench or FFU (Fan Filter Unit) clean operation station, is an air purification device that provides a local dust-free and sterile environment through a HEPA filtration system. It is primarily used in fields such as biopharmaceuticals, electronics manufacturing, medical and health, and precision instrument production, to improve process conditions and ensure operational safety.

The equipment is categorized into vertical and horizontal airflow types based on the direction of airflow. Vertical flow models, which have higher noise levels from top-mounted fans, are commonly used in the pharmaceutical industry, while horizontal flow models, with lower noise, are prevalent in the electronics sector.

‌Key Features:‌

• ‌Airflow Types:‌ Vertical or horizontal unidirectional airflow (ensuring Class 100 cleanliness).
• ‌Core Components:‌ Equipped with HEPA/ULPA filters, sliding door seals, and dedicated filtration channels. Some models include UV sterilization.
• ‌Applications:‌ Protects samples from contamination (unlike biosafety cabinets, which also safeguard operators).
