The Clean Booth (Down Flow Booth) is a modular cleanroom system designed for applications requiring controlled particulate environments. The system utilizes HEPA filtration with 99.995% efficiency at 0.3μm particles to maintain ISO 5 (Class 100)/Class A cleanliness standards through vertical laminar airflow. Available in three configurations (2000mm, 3000mm, and 4000mm width options), the booth features aluminum alloy frame construction with anti-static dustproof curtain walls.
The system employs multiple Fan Filter Units (FFUs) with microprocessor-based control to establish uniform downward airflow patterns within the work zone. Each configuration incorporates dedicated HEPA filtration arrays (4, 6, or 12 units respectively) with power consumption scaling from 800W to 2800W based on booth size. The modular design accommodates various laboratory workflows requiring contamination control in pharmaceutical, biotechnology, and analytical chemistry applications.
How It Works
The Clean Booth operates on the principle of vertical laminar airflow to establish a unidirectional flow pattern that continuously sweeps airborne particles away from the work surface. Room air enters through the FFU system where it passes through HEPA filters rated at 99.995% efficiency for 0.3μm particles. The filtered air then flows downward through the work zone at uniform velocity, creating a particle-free environment within the enclosed booth structure.
The microprocessor control system monitors and maintains consistent airflow parameters while the anti-static curtain walls prevent external contamination infiltration. The aluminum alloy frame provides structural integrity while minimizing particle generation from the booth itself. Air exits through the bottom of the work zone, carrying away any particles introduced during work activities.
The modular FFU configuration allows airflow scaling based on booth dimensions, with larger units incorporating additional filter units to maintain uniform air velocity across the expanded work surface. The vertical flow pattern ensures that particles are continuously removed rather than recirculated within the work zone.

| Control System | Microprocessor-based control | Manual controls or basic electronic systems | Automated monitoring maintains consistent environmental parameters without constant manual adjustment. |
| FFU Distribution | Multiple units (4-12 based on size) | Single or fewer FFU units in comparable sizes | Multiple FFU arrangement ensures more uniform airflow distribution across larger work surfaces. |
| Frame Construction | Aluminum alloy with anti-static curtains | Steel frames or rigid panel construction | Aluminum construction reduces particle generation while anti-static curtains prevent electrostatic particle attraction. |
The Clean Booth system provides ISO 5 cleanliness classification through high-efficiency HEPA filtration and modular sizing options. The microprocessor control system with multiple FFU units ensures consistent airflow distribution across the work zone, while aluminum alloy construction minimizes particle generation from the booth structure itself.
Practical Tips
Verify airflow velocity uniformity across the work surface using a calibrated anemometer at multiple measurement points during initial installation and periodic validation.
Why: Uniform airflow ensures consistent particle removal efficiency across the entire work zone.
Monitor pressure drop across HEPA filters monthly and maintain log of readings to predict filter replacement timing before performance degradation.
Why: Proactive filter maintenance prevents gradual loss of cleanliness levels that could compromise experimental results.
Allow the booth to operate for at least 15-20 minutes before beginning work to establish stable airflow patterns and remove any particles disturbed during startup.
Why: Initial purge time ensures optimal cleanliness levels are achieved before introducing materials or beginning procedures.
If particle counts begin to increase, first check for damage or gaps in curtain seals before assuming filter failure.
Why: Seal integrity problems are more common than filter failures and can be resolved without costly filter replacement.
Document particle count measurements at multiple locations within the booth and maintain records for trend analysis over time.
Why: Historical data helps identify gradual performance changes and supports regulatory compliance documentation requirements.
Ensure electrical connections meet local codes and install appropriate circuit protection before initial system startup.
Why: High-power FFU systems require proper electrical safety measures to prevent equipment damage and personnel hazards.
Position materials and equipment to avoid blocking airflow patterns, keeping the center of the work zone clear for optimal particle removal.
Why: Airflow obstruction creates turbulence zones where particles can accumulate rather than being swept away by the laminar flow.

Compliance
What particle size range does the HEPA filtration system effectively remove?
The HEPA filters achieve 99.995% efficiency at 0.3μm particles, with higher efficiency for larger particles. For smaller particles below 0.3μm, consult product datasheet for specific filtration performance curves.
How do I verify that the booth maintains ISO 5 cleanliness during operation?
Use a calibrated particle counter to measure particle concentrations at multiple points within the work zone. ISO 5 classification requires ≤3,520 particles/m³ at 0.5μm and ≤29 particles/m³ at 5μm.
What is the recommended frequency for HEPA filter replacement?
Filter replacement depends on usage intensity and environmental conditions. Monitor pressure drop across filters and replace when airflow velocity drops below specification or particle counting indicates decreased efficiency.
Can the booth accommodate equipment that generates heat or chemical vapors?
The booth is designed for particulate control only. Heat-generating equipment may affect airflow patterns, and chemical vapors require additional exhaust systems not provided with the standard booth configuration.
How does airflow velocity vary across different booth sizes?
Each booth size incorporates proportional FFU units to maintain uniform airflow velocity across the work surface. Specific velocity measurements should be verified during installation validation.
What electrical requirements are needed for installation?
Power consumption ranges from 800W to 2800W depending on booth size. Consult installation manual for specific voltage, phase, and electrical connection requirements for your facility.
How does this compare to biological safety cabinets for cell culture applications?
Clean booths provide particle control but lack the personnel and product protection features of biological safety cabinets. Use clean booths when enhanced environmental cleanliness is needed beyond standard BSC capabilities.
