What Is a Laminar Flow Clean Bench?

A laminar flow clean bench provides a localized clean working area by directing HEPA-filtered, unidirectional airflow across the work surface.

Available in vertical and horizontal airflow configurations, these workstations help reduce airborne particle contamination during non-hazardous sample handling, inspection and precision assembly.

When properly configured and performance-tested, a clean bench can provide an ISO Class 5 working zone without requiring the entire surrounding room to meet the same cleanliness classification.

How Vertical and Horizontal Clean Benches Work？

HEPA-filtered airflow is directed vertically or horizontally across the work zone to help minimize airborne particle contamination.

Vertical laminar flow clean bench Working principle

Vertical Laminar Flow

Room air enters through the upper pre-filter, passes through the fan and overhead HEPA filter, then flows vertically downward across the working area to help minimize airborne particle contamination.

Horizontal laminar flow clean bench Working principle

Horizontal Laminar Flow

Room air enters through the lower intake and pre-filter, passes through the fan and rear HEPA filter, then flows horizontally across the working area toward the front opening.

FAQs

Answers to common questions about clean bench selection, ISO Class 5 performance, customization, testing and maintenance.

The clean bench is a work area or work earea ensures that the work surface is constantly flooded with HEPA-filtered air in a laminar flow. Unlike a biological safety cabinet, the clean bench protects the work on the work surface, but not personnel or the surrounding environment from aerosols created on the work surface. The HEPA air filter can trap 99.999% of particles with a diameter greater than 0.3 microns.

The Vertical Laminar Flow benches are manufactured with rear wall perforations to reduce turbulence by removing a small amount of air at the rear of the cabinet.

Vertical flow clean bench

The Horizontal Laminar flow benches do not directly impinge upon the work surface or encounter turbulence but rather is smoothly drawn across it.

Horizontal flow clean bench

Yes. A properly designed and configured laminar flow clean bench can provide a localized ISO Class 5 work zone.

However, HEPA filtration alone does not guarantee ISO Class 5 performance. Cleanliness classification should be verified through airborne particle testing in accordance with ISO 14644-1 under defined operating conditions.

ISO Class 5 applies to the tested work zone, not automatically to the surrounding room. Additional qualification may be required for regulated applications.

There are severl differences between clean  bench & Bioasafety cabinet

The clean bench ensures that the work surface is constantly flooded with HEPA-filtered air in a laminar flow. It is in a positive environment.

The clean bench protects the work on the work surface, but not personnel or the surrounding environment from aerosols created on the work surface.

The Clean bench do not provide any protection to the worker. They are designed to provide a sterile environment to protect the product. Air potentially contaminated with infectious agents may be blown towards the worker.

Biosafety cabinets protect the product as well as the user and the environment. They operate under negative air pressure , protecting the user from exposure to aerosolized infectious agents. The air sucked into the hood is sterilized by high efficiency particulate air (HEPA) filtration before being exhausted out, thereby protecting the environment.

Biosafety Cabinets are similar to the Laminar Air Flow cabinets. They too contain HEPA filters but there is one dissimilarity that Biosafety Cabinets offers complete protection to the users against harmful pathogens, since the contaminated air is filtered before it can come in contact with the users.

Many users don’t know the difference between clean bench and laminar flow hood, There are a lot of misconceptions about them:

Clean bench

A clean bench is generally a self-contained workstation with an integrated work surface, filtration system and airflow controls.

Laminar flow hood

A ceiling-mounted laminar flow hood supplies filtered air over a designated process area, production line or workstation without necessarily including an integrated bench.

Both can provide localized clean airflow, but their installation methods, working area coverage and integration requirements differ. Selection depends on the process layout and cleanliness requirements.

Yes. Flair offers configurable clean benches to accommodate different workspace and project requirements.

Depending on the model, available options may include overall and work zone dimensions, stainless steel or powder-coated construction, vertical or horizontal airflow designs, fan speed controls, lighting, electrical outlets and mobility features.

Project-specific GA drawings can be provided to support equipment selection and installation planning.

Factory inspection and testing can be arranged according to the clean bench model and agreed project requirements.

Available checks may include visual inspection, electrical and control system operation, fan performance and airflow velocity measurements. HEPA filter integrity testing and additional performance verification can be specified where applicable.

Relevant inspection records and technical documentation can be supplied as agreed before shipment.

Routine maintenance includes checking and cleaning or replacing pre-filters, inspecting airflow performance and monitoring the condition of the HEPA filtration system.

HEPA filter replacement procedures depend on the clean bench design and filter mounting arrangement. Replacement should be performed by qualified personnel following the manufacturer’s instructions.

After replacement, airflow performance and filter integrity should be verified as required. Maintenance intervals depend on operating conditions, usage and filter condition.
