Top 5 Things to Consider Before Buying a Laminar Flow Clean Bench for Your Modular Cleanroom

When building a truly efficient, safe, and standard-compliant cleanroom or modular operating room, many clients often focus solely on core equipment such as the air handling unit (AHU), air flow ducts (FFU), air showers, and cleanroom doors, but overlook an equally critical control node: the laminar flow clean bench.

This equipment provides a localized ISO Class 5 clean environment for key processes such as product testing, drug preparation, and sample preparation. It is an indispensable cleanroom support system in fields such as chip manufacturing, drug development, cosmetic filling, and food quality inspection.

However, during actual project implementation, many buyers are prone to selection errors due to a lack of understanding of the equipment details. In this article, Amber will help you determine the optimal laminar flow bench for your cleanroom system by analyzing five key factors.

Five Essential Factors to Consider Before Choosing a Laminar Flow Clean Bench for a Modular Cleanroom

Clarify the Application Purpose and Risk Level

Before you even open your shopping list, ask yourself: "What process will my clean bench be used for?"

Different process steps have different cleanliness requirements. For example:

• Development or photolithography in a chip fab may require partial ISO 5 or higher.

• Drying or filling areas in pharmaceutical production may require GMP-compliant Class A operating areas.

• Micro-formulation areas in cosmetics require a higher focus on both particle and microbial control.

• After clarifying these applications, you can select the appropriate technical parameters, including airflow type (vertical/horizontal), filtration level (HEPA/ULPA), and air speed control mode.

Vertical or Horizontal Laminar Flow?

The Laminar Air Flow Bench is available in two configurations: vertical laminar flow and horizontal laminar flow.

While both provide unidirectional clean air flow, their application scenarios differ significantly:

• Vertical laminar flow: Airflow flows vertically downward from the top, preventing operator breathing or movement from disturbing the product. This is suitable for pharmaceutical and medical device applications requiring high levels of cleanliness.

• Horizontal laminar flow: Airflow flows from the rear toward the operating area. This is suitable for applications such as sample preparation and precision electronic assembly, where product protection requirements are high and operator exposure risk is low.

Most customers are entirely concerned with the outlook of the equipment when choosing such equipment without considering the effects of airflow direction on the safety and the control of contaminants during the operation. Indeed, cross-contamination risk can be minimized, and the level of compliance in the workplace can be enhanced through scientifically planned airflow.

Size, Configuration, and Customization to Fit Your Modular Layout

The Laminar Flow Work Bench is not a one-size-fits-all standard product.

For most modular cleanroom projects, space is tight and functional areas are diverse, so it's important to consider:

• Can the width and height of the equipment be customized to meet on-site specifications?

• Can it be configured with multiple workstations, built-in outlets, lighting, and a UV germicidal lamp?

• Can the housing be made of 304/316 stainless steel to meet corrosion and disinfection requirements?

• Can it be portable and have casters for convenience?

Here's a real customer example: We designed a built-in, two-station vertical laminar flow bench for a cosmetics laboratory. It not only seamlessly integrated into the overall work surface, but also saved the client 40% in space costs. This kind of customization is a key advantage of an experienced supplier.

Does the filtration system meet certification standards?

The core value of a clean bench lies in its filtration performance. Before purchasing, we recommend confirming the following:

• Whether it uses genuine HEPA or ULPA filters with a filtration efficiency of 99.99% or higher.

• Whether it has air velocity/pressure differential alarms for daily monitoring.

• Whether the equipment is CE-certified or compliant with GMP/ISO 14644 standards.

• Whether it supports factory test reports and third-party verification services.

Especially in highly regulated industries like pharmaceutical manufacturing and vaccine development, equipment certification is directly related to whether a project can successfully pass GMP audits.

Service Response and Installation and Commissioning Capabilities

Don't underestimate the installation and commissioning of a laminar flow bench. It requires coordination with the cleanroom's overall air volume, air pressure differential, and temperature and humidity control systems to achieve true cleanroom isolation.

Therefore, it's strongly recommended to select an equipment service provider that offers on-site installation and after-sales support.

The Amber Team, with over 17 years of industry experience, not only provides a complete set of design drawings, but also offers on-site commissioning, operational training, and maintenance services, ensuring a turnkey delivery.
