The HEPA Filtered Vertical Laminar Flow Hood is a professional air purification unit engineered to deliver a localized Class 100 clean environment for high-precision lab operations, manufactured with 19 years of industrial innovation and quality assurance. As a core piece of lab clean air equipment, this hood is flexibly mountable above critical process points, converting ordinary lab spaces into GMP-A grade laminar flow work zones with vertical unidirectional airflow. Air is filtered through a high-efficiency HEPA filter at a stable wind speed, forming a uniform clean air layer that eliminates airborne contaminants and meets the strict sterility requirements of lab processes. It can be used independently for single workstations or combined to create strip-shaped clean areas, and can even be upgraded to a mobile clean laminar flow cart or isolation device for flexible process needs. Ideal for lab buyers in pharmaceuticals, biotech, and precision testing, this hood balances ultra-high cleanliness with user-friendly operation, making it a staple for dust-free and sterile lab workflows.
Full SUS304 Stainless Steel Construction: Corrosion-resistant, easy to sterilize and clean, compliant with GMP and lab hygiene standards.
Smart Touch Screen Control: Intuitive operation interface for adjusting airflow parameters and monitoring device status in real time.
24/7 Real-time Cleanliness Monitoring: Tracks air speed, filter efficiency and pressure differentials to ensure consistent Class 100 performance.
High-Efficiency HEPA Filtration: 99.99% filtration efficiency for 0.3μm particles, achieving ultra-high cleanliness in the working area.
Professional Detection Interfaces: Equipped with SUS PAO dust outlet and DOP inspection port for convenient filter performance testing and certification.
Low-Noise Operation: Optimized air duct design keeps noise levels at lab-friendly ranges, avoiding interference with precision experiments.
Stable Airflow Output: Fixed air speed of 0.45m/s±20% ensures unidirectional vertical flow and no turbulent air in the work zone.

Site Preparation: Choose a flat, vibration-free lab area with a dedicated 220V power supply; ensure no obstructions above the installation position for air intake.
Main Body Fixation: Mount the hood on a stable lab bench or wall-mount it using the provided brackets; level the body to avoid airflow deviation.
HEPA Filter Installation: Align the HEPA filter with the internal card slot, ensure airtight sealing with the gasket, and lock the fixing clip to prevent air leakage.
Electrical Connection: Connect the power cord to a grounded 220V socket; professional electrician operation is recommended for lab safety compliance.
Commissioning & Testing: Power on and run the hood for 30 minutes; test air speed and uniformity, and perform DOP/PAO testing to verify filtration efficiency.
Calibration & Sign-off: Calibrate the Dwyer manometer to zero; record initial pressure differential data and affix a calibration label for future maintenance.
Pharmaceutical R&D Labs: Aseptic preparation, drug formulation, and sterile sample handling compliant with GMP standards.
Biotechnology Labs: Cell culture, microbial detection, and genetic engineering experiments requiring dust-free and sterile environments.
Precision Electronics Labs: Assembly and testing of microelectronic components and optical parts sensitive to particulate contamination.
Food Safety Labs: Detection of foodborne pathogens and microbial limit tests with strict sterility requirements.
Cosmetics R&D Labs: Formulation and testing of high-end cosmetics to avoid microbial and dust contamination.
Environmental Testing Labs: Analysis of trace pollutants and air particle sampling with clean operation needs.
Custom Dimensions: Non-standard W×D×H sizes to fit specific lab workstation layouts and space constraints.
Mobile Upgrade: Add heavy-duty silent casters and brake systems to convert the hood into a mobile laminar flow cart.
Filtration Grade Upgrade: Custom ULPA filter configuration for 99.999% filtration efficiency for ultra-high precision applications.
Remote Monitoring: Integrate IoT modules for real-time data transmission to lab management systems (pressure, air speed, filter status).
Voltage Adaptation: Custom 110V/380V power supply for global lab users in different regions.
Accessory Customization: Add lab-specific accessories such as stainless steel storage racks, anti-splash baffles, and UV sterilization lamps.
Under normal lab use (8 hours/day), the HEPA filter has a service life of 6-12 months; replacement is required when the pressure differential exceeds 300pa (monitored via the Dwyer manometer).
Yes, the full SUS304 stainless steel construction is corrosion-resistant; the internal electrical components are sealed to prevent moisture damage, suitable for humid labs such as microbial culture.
It meets ISO 14644-1 Class 5 (equivalent to Class 100) and GMP-A grade standards, with test reports available for third-party certification.
Wipe the stainless steel surface with 75% alcohol daily; clean the pre-filter (if equipped) with compressed air every 2 weeks; avoid touching the HEPA filter surface directly.
Yes, the hood is designed with modular connection ports; multiple units can be combined to form a strip-shaped clean area for large-scale lab process lines.
