ZJNF SUS304 High-efficiency 0.3um Particulate Cleanroom Clean Bench Workstation

Clean Bench for Cleanroom‌

A clean bench for a cleanroom is a localized air purification device designed to provide a highly clean environment in specific areas. It is widely used in industries such as pharmaceuticals, biotechnology, food processing, and optoelectronics. Its core function is to remove airborne particles, bacteria, and other contaminants through an efficient filtration system, ensuring a sterile workspace.

‌Working Principle‌

The clean bench draws in ambient air via a fan, which first passes through a pre-filter to capture large particles. The air then flows through a ‌HEPA (High-Efficiency Particulate Air) filter‌ to remove fine particles and bacteria, ultimately delivering clean air in a vertical or horizontal laminar flow to create a sterile environment (typically ISO Class 5 or better). Some models also include ‌UV sterilization lamps‌ for enhanced disinfection.

‌Key Components‌

• ‌Enclosure‌: Seamless, smooth design to minimize dust accumulation and contamination.
• ‌Filtration System‌: Includes a pre-filter (primary) and a HEPA/ULPA filter to ensure air cleanliness.
• ‌Auxiliary Features‌: Equipped with lighting, adjustable work surfaces, and exhaust options for diverse operational needs.

‌Types and Applications‌

1. ‌By Airflow Type‌
   • ‌Vertical Laminar Flow‌: Air flows downward, ideal for high-cleanliness operations (e.g., biological experiments).
   • ‌Horizontal Laminar Flow‌: Air blows horizontally toward the operator, suitable for general cleanroom tasks.
2. ‌By Purpose‌: Includes general-purpose, chemical-resistant, and sterilizing models, selected based on specific requirements.

‌Usage Guidelines‌

• ‌Avoid Obstructions‌: Keep the workspace clear to maintain proper airflow and cleanliness.
• ‌Regular Maintenance‌: Replace filters and clean surfaces periodically to ensure performance.
• ‌Safety Precautions‌: Avoid direct exposure to UV light during sterilization to prevent eye/skin damage.
