Rear-Mounted H14 HEPA Filter of Horizontal laminar flow clean bench

Rear-Mounted H14 HEPA Filtration

The rear-mounted H14 HEPA filter supplies high-efficiency filtered air directly across the work zone, helping maintain an ISO Class 5 environment for contamination-sensitive processes.

Uniform Horizontal Laminar Airflow

HEPA-filtered air flows uniformly from the rear of the bench toward the open front, continuously sweeping airborne particles away from the critical work area.

Open & Unobstructed Work Zone

The rear-mounted filtration design provides a spacious work area with clear overhead access for samples, instruments and precision components.

How Does a Horizontal Laminar Flow Clean Bench Work?

Room air is pre-filtered and delivered through the rear-mounted HEPA filter to create uniform horizontal airflow across the clean working area.

Horizontal laminar flow clean bench Working principle

① Room Air Intake

Ambient room air enters the unit through the air intake.

② Pre-Filtration

The pre-filter captures larger airborne particles.

③ Fan & Air Supply

The fan supplies stable airflow through the rear plenum.

④ Rear HEPA Filtration

Air passes through the rear-mounted H14 HEPA filter.

⑤ Horizontal Laminar Airflow

Filtered air flows uniformly toward the open front across the work zone.

The horizontal clean bench is designed primarily for product protection and should not be used for hazardous materials requiring personnel or environmental protection.

FAQs

Find answers to common questions about horizontal airflow, ISO Class 5 cleanliness, HEPA filtration, product protection and customization.

1. What is a horizontal laminar flow clean bench?

A horizontal laminar flow clean bench is a clean-air workstation designed to protect non-hazardous products, samples and sensitive processes from airborne particle contamination. Room air is pre-filtered and then passed through a high-efficiency HEPA filter mounted at the rear of the working area.

The filtered air flows horizontally across the work surface toward the open front, creating a continuous unidirectional clean airflow. A properly designed and maintained system can provide an ISO Class 5 localized clean working environment for laboratory, electronics, pharmaceutical and precision manufacturing applications.

2. What is the main advantage of horizontal laminar airflow?

Horizontal laminar airflow delivers HEPA-filtered air directly from the rear filter across the working area toward the open front. This airflow pattern provides a uniform clean-air stream over samples and sensitive components while minimizing turbulence within the critical work zone.

Because the main HEPA filter is positioned behind the work area rather than directly above it, horizontal clean benches can also provide unobstructed overhead workspace for handling smaller equipment, samples and precision components.

3. What is the difference between horizontal and vertical laminar flow clean benches?

The main difference is the direction and location of the HEPA-filtered airflow. In a horizontal clean bench, the HEPA filter is typically located at the rear of the work area and clean air flows horizontally toward the open front.

In a vertical clean bench, filtered air is supplied from above and moves downward across the work surface. Horizontal airflow is often selected when direct, unobstructed clean airflow across the work surface is preferred, while vertical airflow may be more suitable when equipment or process layouts could obstruct a horizontal airflow path.

The appropriate configuration should be selected according to the process, equipment arrangement and contamination-control requirements.

4. What cleanliness level can a horizontal clean bench provide?

A properly designed and maintained horizontal laminar flow clean bench can provide an ISO Class 5 clean working environment under specified operating conditions.

Actual performance depends on HEPA filter efficiency, airflow velocity and uniformity, filter integrity, equipment condition and operating practices. For projects requiring documented performance, particle concentration, airflow velocity and HEPA filter integrity can be tested according to applicable cleanroom standards and project requirements.

5. What should not be handled in a horizontal clean bench?

A horizontal clean bench should not be used for hazardous biological agents, toxic chemicals or other materials that require operator or environmental protection.

The horizontal airflow moves from the rear HEPA filter across the work surface toward the open front and operator. The clean bench is therefore designed primarily to protect the product or sample from airborne contamination rather than to protect personnel.

Applications involving hazardous biological materials should use appropriate containment equipment, such as a certified biological safety cabinet, according to the applicable safety requirements.

6. Can horizontal clean benches be customized?

Yes. Horizontal laminar flow clean benches can be configured according to the required working dimensions, cleanliness level, material, airflow performance and installation conditions.

Available options may include different working widths, stainless steel construction, HEPA or ULPA filtration, fan and control systems, lighting, electrical outlets and mobile or fixed support structures.

Customers can provide the required working area dimensions, material, power supply and process requirements, and Flair can recommend a suitable configuration for the project.
