latest company case about Guangzhou Cleanroom Construction Co., Ltd. Certifications

In biological laboratories, CDC centers, hospital clinical laboratories, and research institutions, a biological safety cabinet is not just a basic piece of equipment—it is the core barrier that ensures personnel safety, sample integrity, and environmental protection.

This A2 Biological Safety Cabinet integrates an ultra-high-efficiency ULPA filtration system, full steel construction, multiple patented technologies, and an intelligent digital control system to deliver a stable, reliable, and traceable protection solution for high-risk laboratory environments.

I. Basic Product Specifications

Product Name: A2 Biological Safety Cabinet
Dimensions (W × D × H): 2000 × 800 × 2140 mm
Cabinet Material: Cold-rolled steel (full steel construction)
Work Surface: Anti-fingerprint SUS304 stainless steel
Inner Chamber: One-piece integrated anti-fingerprint SUS304 stainless steel

The robust full-steel structure ensures long-term operational stability and durability, making it suitable for high-intensity laboratory use.

II. ULPA Ultra-High-Efficiency Filtration – Achieving ISO Class 4 Cleanliness

The cabinet is equipped with a ULPA (Ultra-Low Penetration Air) filter with a filtration efficiency of:

99.999% @ 0.12 μm

This advanced filtration system provides ISO Class 4 cleanliness in the working area, effectively capturing particles and biological contaminants.

Easy Filter Replacement Design (Patent No.: 201921368798.)

Optimized structure for convenient maintenance

Filter lifespan up to 5 years without replacement

Reduced long-term operating costs

III. Constant Airflow Control & Low-Noise Air Duct Structure

The cabinet uses an imported high-performance fan to ensure sufficient airflow while maintaining constant air volume control.

Even when filter resistance increases by 200%:

Total airflow reduction does not exceed 10%

Unique Air Duct Structure (Patent No.: 201921547107.2)

Optimized airflow organization

Reduced operational noise

Enhanced airflow stability

IV. Triple Biological Safety Protection Standards

The cabinet passes strict biological performance testing to ensure comprehensive triple protection:

Product Protection: Total colony count ≤ 5 CFU/test

Cross-Contamination Protection: Total colony count ≤ 2 CFU/test

Personnel Protection: Total colony count ≤ 5 CFU/test

This ensures both sample integrity and operator safety during laboratory procedures.

V. Leak-Proof Technology & Negative Pressure Structure

Leak-Proof Patent Technology (Patent No.: 201921547042.1)

Cabinet pressurization up to 800 Pa

Pressure drop does not exceed 10%

All biologically contaminated areas inside the cabinet are maintained under negative pressure or surrounded by negative-pressure airflow channels and ventilation systems to prevent contamination leakage.

VI. Core Patented Airflow Technologies

High Airflow Uniformity Technology (Patent No.: 202110829159.4)

Average airflow velocity deviation within ±20% or +0.08 m/s

Full airflow coverage across the working area

Zero Finger-Pinch Safety Design (Patent No.: 202122424808.0)

Enhanced operational safety

Reduced risk of accidental injury

VII. Fully Digital Intelligent Control System

The cabinet features a large intelligent touchscreen interface for comprehensive digital management:

Real-time display of airflow velocity, temperature, humidity, and filter lifespan

UV lamp and fan scheduling timer system

Remote-control operation capability

Network transmission interface for data integration

High-Sensitivity Air Velocity Sensor

Measurement range: 0–1 m/s

Accuracy: 0.01 m/s

Response time: Approximately 4 seconds to reach T90

This ensures precise and real-time airflow monitoring.

VIII. Ergonomic Design

The cabinet is engineered with user comfort in mind:

Inclined front design reduces glare

Improved visibility for operators

Maintains comfortable working posture

The base is equipped with FUMA casters for easy mobility, along with built-in threaded support feet for adjustable leveling.

IX. Silver-Ion Antibacterial Coating

The cabinet surface is coated with a silver-ion antibacterial layer that effectively inhibits microbial growth, enhancing long-term operational safety.

Conclusion

The A2 Biological Safety Cabinet integrates ULPA ultra-high-efficiency filtration, constant airflow control, leak-proof structure, multiple patented technologies, and intelligent digital management into one comprehensive biosafety solution.

While ensuring the safety of personnel, samples, and the environment, it also improves operational stability and maintenance efficiency.

This product is especially suitable for:

Biosafety laboratories

Hospital clinical laboratories

Centers for Disease Control (CDC)

Research institutions

High-level microbiological research environments

Customized configurations and professional technical solutions can be provided according to laboratory classification and specific project requirements.
