ZJNF Cleanroom Level 1000 Air Cleaning Equipment Dust Free Desktop Laminar Flow Hood

Core Definition and Function
The laminar flow workbench in a cleanroom is a box type equipment that forms a vertical/horizontal unidirectional airflow through an efficient filter, providing a local Class 100 (ISO 5) clean environment to protect operating samples from contamination
Its core functions include:
Maintain stable wind speed and cleanliness
Directed emission of polluted air
Suitable for precision operations such as biopharmaceuticals and electronic manufacturing
Key factors for selection
Airflow mode selection:
Vertical flow: top-down airflow, comprehensive protection (recommended for biological experiments)
Horizontal flow: direct operation, suitable for electronic assembly
Core parameters:
Purification rate: ≥ 99.99% (high-efficiency filter standard)
Noise: ≤ 50dB (applicable in laboratory)
Processing air volume: 1000-2400m ³/h (depending on the size of the operating area)

Maintenance and Standards
Daily maintenance: surface cleaning, UV lamp disinfection, filter leakage testing
Industry standard: Must comply with the "Standard for Laminar Flow Clean Workbench" (JG/T 19-1999)
Safety Reminder: The horizontal flow workbench is prohibited from handling hazardous substances
