Note: Clean benches are designed primarily for product protection and are not intended for handling hazardous biological materials requiring personnel protection.
Find answers to common questions about vertical airflow, ISO Class 5 cleanliness, HEPA filtration, maintenance and customization.
1. What is a vertical laminar flow clean bench?
A vertical laminar flow clean bench is a localized clean-air workstation designed to protect products, samples, and sensitive processes from airborne particle contamination. Room air is drawn into the unit, passes through a pre-filter and high-efficiency HEPA filter, and is then supplied vertically downward across the working area.
The filtered airflow helps maintain an ISO Class 5 clean work zone, making vertical clean benches suitable for laboratories, pharmaceutical processing, electronics assembly, medical device manufacturing, and other contamination-sensitive applications.
A clean bench is primarily designed for product protection and should not be used for hazardous biological materials that require operator or environmental protection.
2. How does a vertical flow clean bench work?
A vertical flow clean bench draws ambient room air through a pre-filter to remove larger particles. The fan then pushes the air through a high-efficiency HEPA filter located above the working area.
After filtration, clean air flows vertically downward across the entire work surface at a controlled and uniform velocity. This continuous HEPA-filtered airflow helps reduce airborne particles and minimizes contamination within the critical working zone.
The air is finally discharged through the front opening of the clean bench, maintaining a stable clean environment for contamination-sensitive operations.

3. What is the difference between vertical and horizontal clean benches?
The main difference is the direction of HEPA-filtered airflow.
In a vertical flow clean bench, filtered air moves downward from the HEPA filter above the work area toward the work surface. This design provides a compact working configuration and is suitable for many laboratory, pharmaceutical, electronics, and precision assembly applications.
In a horizontal flow clean bench, filtered air moves horizontally from the rear HEPA filter toward the operator.
The appropriate airflow configuration depends on the process, equipment placement, workspace requirements, and contamination-control needs. Flair can provide both vertical and horizontal clean bench configurations according to project requirements.
4. What cleanliness level can a vertical laminar flow clean bench provide?
A properly designed and maintained vertical laminar flow clean bench can provide an ISO Class 5 clean working environment within the protected work zone under specified operating conditions.
The cleanliness level depends on several factors, including HEPA filter efficiency, airflow velocity and uniformity, filter integrity, equipment condition, installation environment, and operating practices.
For applications requiring documented cleanliness performance, airflow velocity, HEPA filter integrity, particle concentration, and other parameters can be tested according to applicable project requirements and cleanroom standards.
5. How often should the HEPA filter in a clean bench be replaced?
There is no fixed replacement interval for every clean bench. HEPA filter service life depends on operating hours, ambient air quality, pre-filter maintenance, particle loading, and the conditions of the installation environment.
The HEPA filter should be inspected and its performance checked periodically. Replacement may be required when airflow can no longer be maintained at the specified velocity, pressure resistance becomes excessive, the filter is damaged, or the HEPA filter fails an integrity test.
Regular cleaning or replacement of the pre-filter can also help reduce particle loading and extend the service life of the HEPA filter.
6. Can the size and configuration of the vertical flow clean bench be customized?
Yes. Flair can customize vertical laminar flow clean benches according to the required working area, process layout, cleanliness requirements, and installation conditions.
Available configurations may include different working widths, single- or multi-person workstations, stainless steel materials, HEPA filter specifications, fan systems, lighting, electrical outlets, control systems, side panels, and mobile caster options.
For customized projects, customers can provide the required external dimensions, working area size, material, power supply, cleanliness level, and any special functional requirements. Our engineering team can then recommend a suitable clean bench configuration for the application.
