Product Description
A vertical laminar flow hood is a core purification device that provides a localized, high-purity, sterile operating environment. Designed based on the principle of vertical unidirectional airflow, this high-performance Sterile Workbench employs a top-down airflow configuration: air is purified through two stages—a pre-filter and a high-efficiency particulate air (HEPA/ULPA) filter—and then continuously flows over the entire work surface in the form of uniform vertical laminar flow.
The top-down clean airflow works in conjunction with the semi-enclosed operating area to not only create a robust air barrier that effectively prevents the intrusion of external contaminated air but also rapidly removes dust particles and microorganisms generated during operations. This ensures that this Class 100 Clean Bench consistently meets the ISO Class 5 (Class 100) cleanliness standard, providing comprehensive protection for experimental samples against cross-contamination while minimizing the impact of operational odors on personnel. As an essential Laboratory Clean Bench, this equipment is widely used in demanding environments such as biopharmaceuticals, electronics manufacturing, food testing, physical and chemical laboratories, and precision instrument assembly. It serves as a critical piece of foundational equipment for contamination control in cleanroom engineering and controlled environments.
II. Key Selling Points
① Class 100 Cleanliness, High-Efficiency Filtration Performance
Equipped with an H14-grade HEPA filter, this Class 100 Clean Bench achieves a filtration efficiency of over 99.99% for 0.3 μm particles. The work area consistently maintains a Class 100 cleanliness level (per Federal Standard 209E), with a colony count of ≤0.5 colonies per dish per hour, fully meeting the sterile and dust-free requirements of demanding applications such as microbiological experiments and precision assembly.
② Vertical Laminar Flow Design, Uniform Air Distribution Throughout
Featuring a vertical unidirectional laminar flow structure, airflow evenly covers the entire work surface from top to bottom. The air velocity is multi-stage adjustable from 0.3 to 0.6 m/s, eliminating dead zones and vortices to ensure consistent cleanliness throughout the work area. This effectively prevents cross-contamination of samples while maintaining a comfortable operating environment for technicians using this Sterile Workbench.
③ High-Quality Materials and Construction for Durability and Easy Cleaning
The cabinet is made of high-quality cold-rolled steel plate with an electrostatic powder-coating finish, making it corrosion-resistant and easy to clean. The work surface of this Laboratory Clean Bench is constructed from brushed 304 stainless steel in a single-piece, seamless design that is wear-resistant and corrosion-resistant, facilitating daily disinfection and cleaning while complying with hygiene standards for the pharmaceutical and food industries.
④ Low-Noise, Low-Vibration Operation Ensures Operational Precision
Equipped with a high-quality centrifugal fan and a vibration-damping and noise-reduction structure, the unit operates at a noise level of < 62 dB(A) and a half-peak vibration amplitude of le4 on the work surface. This ensures a quiet laboratory environment while meeting the stringent vibration control requirements of precision optical and electronic component assembly.
⑤ Multiple Safety Features for Greater Peace of Mind
This Sterile Workbench comes standard with a UV sterilization lamp for comprehensive disinfection of the work area; it is equipped with multiple alarm functions—including fan failure, filter clogging, and abnormal airflow—to promptly alert users to equipment malfunctions; select models support interlocks between the UV lamp, fan, and viewing window to prevent accidental injury.
⑥ User-Friendly Design for More Efficient Operation
Engineered as an ergonomic Laboratory Clean Bench, the system is equipped with a high-brightness lighting system (illuminance ≥ 300 Lux)) that provides soft, non-glare lighting; the work area features a transparent tempered glass window for an unobstructed view; thoughtful design details—such as a height-adjustable work surface, built-in power outlets, and storage racks—align with daily work habits to enhance workflow efficiency.

IIIII.A Comprehensive Comparison of Vertical and Horizontal Laminar Flow Cabinets
| Comparison Dimension | Vertical Laminar Flow Cabinet | Horizontal Laminar Flow Cabinet |
|---|---|---|
| Airflow Direction | Vertical downward airflow from top HEPA filter, returns through bottom / side vents after passing through the work zone | Horizontal forward airflow from rear HEPA filter, discharges from the front after flowing across the work surface |
| Filter Location | Installed at the top of the cabinet | Installed at the rear of the cabinet |
| Cleanliness Class | Class 100 (ISO Class 5), stable airflow organization, excellent cleanliness uniformity across the entire work zone | Class 100 (ISO Class 5), uniform air velocity on work surface, high close-range cleanliness |
| Personnel Protection | Good. Airflow flows downward without blowing directly at the face, carries away aerosols generated during operation and reduces inhalation risk | Weak. Airflow blows directly toward operators, and may carry sample particles and reagent fumes toward personnel |
| Sample Protection | Excellent. Vertical airflow forms a full-range air curtain barrier, effectively blocks external contaminants with low cross-contamination risk | Excellent. Horizontal airflow flows parallel to the sample surface with low dust settling risk; but operator hair and clothing fibers may be carried into the airflow |
| Space Footprint | Small footprint with shorter cabinet depth, ideal for compact spaces; requires ceiling height clearance | Large footprint with deeper cabinet, requires rear maintenance space; no special ceiling height requirement |
| Internal Space Feature | Ample vertical height, suitable for tall laboratory equipment and vessels | Wide horizontal space, suitable for long and flat workpieces; limited vertical height |
| Airflow Interference Risk | Tall stacked items may block airflow and form eddy dead zones | Airflow parallel to work surface, common workpieces cause less interference and more uniform airflow |
| Maintenance Cost | Top filter replacement is convenient, longer filter service life, lower overall maintenance cost | Rear filter replacement requires reserved space; airflow carries human contaminants, faster filter wear and more frequent replacement |
| Operation Convenience | Mostly semi-enclosed structure, arm-reach operation, slightly limited for large item access | Mostly open structure, no front obstruction, flexible item access and higher operation efficiency |
