The Vertical Laminar Flow Cabinet provides a controlled, sterile work environment for applications requiring contamination-free conditions. This single-user unit features vertical downward airflow with HEPA H14 filtration, achieving ISO level 5 (100 levels) cleanliness standards. The cabinet maintains airflow velocity between 0.2-0.45 m/s with filtration efficiency of ≥99.995% for 0.3 μm particles.
Operating at ≤65 dB(A) with minimal vibration (≤5 μm rms), the cabinet provides a stable working surface at 750 mm height. The front window safety height of 200 mm with maximum opening of 350 mm allows comfortable manipulation while maintaining containment. Internal lighting provides ≥300 lx illumination for detailed work.
How It Works
The cabinet operates on the principle of unidirectional vertical airflow combined with high-efficiency particulate air (HEPA) filtration. Room air is drawn into the cabinet through intake vents and passes through a HEPA H14 filter that removes ≥99.995% of particles 0.3 μm and larger. The filtered air then flows vertically downward across the work surface at a controlled velocity of 0.2-0.45 m/s.
This downward laminar flow creates a sterile work zone by continuously sweeping particles and contaminants away from the work surface and out through the front opening. The vertical flow pattern prevents contaminated air from entering the sterile work zone while allowing easy access for manipulation. The front window acts as a physical barrier while maintaining the airflow pattern.
The cabinet maintains sterility through continuous air exchange and filtration rather than air recirculation. This ensures that any particles generated within the work zone are immediately removed by the downward airflow, maintaining the ISO level 5 cleanliness classification throughout operation.

This cabinet offers HEPA H14 filtration with variable airflow control and low-noise operation. The ISO level 5 cleanliness rating and minimal vibration design provide a stable, sterile work environment suitable for critical applications requiring precise contamination control.
Practical Tips
Verify airflow velocity quarterly using a calibrated anemometer at a grid of points across the work surface.
Why: Consistent airflow is critical for maintaining sterile conditions and preventing contamination.
Monitor HEPA filter pressure differential and replace filter when resistance exceeds manufacturer specifications.
Why: Clogged filters reduce airflow velocity and compromise sterility performance.
Allow cabinet to run for minimum 30 minutes before use and avoid placing items that obstruct airflow patterns.
Why: Proper airflow establishment and unobstructed flow paths are essential for maintaining sterile conditions.
Keep the front window opening at the specified 200 mm safety height during operation.
Why: Proper window positioning maintains the designed airflow pattern and containment effectiveness.
Perform monthly settling plate tests in multiple locations within the work zone to verify sterility.
Why: Regular microbial monitoring confirms the cabinet is maintaining specified cleanliness levels.
If airflow velocity decreases, check for obstructions and verify HEPA filter condition before assuming equipment failure.
Why: Many airflow issues are caused by blockages or filter loading rather than blower problems.
Clean work surfaces with appropriate disinfectant before and after each use session.
Why: Regular cleaning prevents accumulation of contaminants that could compromise sterile conditions.
Schedule annual professional certification including airflow uniformity, filter integrity, and vibration measurements.
Why: Comprehensive testing ensures all performance parameters remain within specification for reliable operation.

Compliance
What is the filtration efficiency and how does it compare to other HEPA grades?
The cabinet uses HEPA H14 filters with ≥99.995% efficiency for 0.3 μm particles. This exceeds H13 filters (99.95% efficiency) and provides superior contamination control for critical applications.
How do I verify the cabinet is maintaining proper airflow velocity?
Use a calibrated anemometer to measure airflow at multiple points across the work surface. Velocity should consistently measure between 0.2-0.45 m/s during operation.
What maintenance is required for optimal performance?
Regular cleaning of work surfaces, periodic HEPA filter replacement based on pressure differential monitoring, and annual airflow velocity verification are essential maintenance procedures.
Can the work surface height be adjusted for different users?
Yes, the standard 750 mm work surface height can be customized during installation to accommodate specific ergonomic requirements or laboratory configurations.
How do I validate sterility performance?
Perform settling plate tests to verify colony counts remain ≤0.5 CFU/30min. This should be done initially and periodically as part of quality assurance protocols.
What power supply options are available?
Standard configuration is 220V±10%, 50Hz with 150VA rated power. Optional 110V±10%, 60Hz power supply is available for North American installations.
How does this compare to horizontal laminar flow cabinets?
Vertical flow cabinets provide better containment as particles are swept downward away from the work zone, while horizontal flow may blow contaminants toward the operator or adjacent work areas.
