GMP Laminar Airflow Solution for Pharmaceutical Manufacturing

Sterile pharmaceutical manufacturing requires highly controlled airflow over product-exposed areas to minimize the risk of airborne contamination.

Airkey is a professional modular cleanroom manufacturer providing factory-prefabricated cleanroom systems for pharmaceutical, biotechnology, medical device, laboratory, and other contamination-sensitive applications. Explore our modular cleanroom solutions to learn more about our system configurations, customization options, and applications.

Airkey supplied a 5㎡ ISO Class 5 laminar airflow hood for a GMP-compliant pharmaceutical manufacturing facility in Australia. The LAF-E35-PS-5P system provides a self-contained ISO 5 environment without requiring ceiling modifications or external ductwork, making it suitable for both new installations and cleanroom retrofit projects.

Project Overview

Pharmaceutical Applications

Laminar airflow protection is particularly important in pharmaceutical manufacturing processes where products or sterile components are exposed to the surrounding environment.

Typical applications include:

Sterile Injectable Manufacturing

Grade A laminar airflow can be used over product-exposed areas in Grade B background environments, including filling lines, sterile component transfer, sampling, and manual intervention stations.

Oral Solid Dosage Manufacturing

For non-sterile tablets and capsules, LAF systems provide localized particle control during raw material weighing, dispensing, sampling, and small-scale clinical trial formulation.

Sterile Topical Preparations

Laminar airflow hoods can also provide controlled protection for sterile products such as eye drops and sterile ointments.

Airkey Engineering Solution

Self-Contained ISO 5 Purification

The unit integrates a centrifugal fan with a two-stage filtration system to achieve ISO Class 5 / Grade A conditions upon power-on.

Because the system is self-contained, no ceiling modification or external ductwork is required. This makes it particularly suitable for upgrading existing facilities and pharmaceutical retrofit projects.

Full SS304 GMP-Oriented Construction

The LAF uses stainless steel construction designed for pharmaceutical environments.

The corrosion-resistant surfaces can withstand regular cleaning with hydrogen peroxide and quaternary ammonium disinfectants.

Transparent PVC strip curtains at the front provide convenient operator access while helping maintain unidirectional airflow and minimize turbulence.

Integrated Validation Features

The standard configuration includes:

• H14 HEPA filter
• Differential pressure display
• PAO test ports
• Variable-frequency speed control
• Cleanroom-grade lighting

A validation documentation package can also be provided, including particle counting and microbiological testing.

Mobile and Flexible Operation

The unit is equipped with silent swivel casters with brakes and adjustable support legs.

This allows the laminar airflow hood to be relocated between workstations within Grade B, C, or D cleanroom environments according to production requirements.

Energy-Efficient Operation

Variable-frequency energy-saving fans provide low-noise operation.

Filter replacement can be completed from inside the LAF without specialized tools, simplifying routine maintenance.

Engineering Highlights

• ISO Class 5 / Grade A laminar airflow protection
• Self-contained purification system
• No ceiling modification or external ductwork
• SS304 pharmaceutical-grade construction
• H14 HEPA filtration
• PAO test ports
• Real-time differential pressure display
• Variable-frequency fan control

Performance Validation

Every laminar airflow hood undergoes multiple tests before delivery.

The validation process includes PAO integrity testing, cleanliness verification, and airflow velocity measurement to verify ISO 5 / Grade A cleanliness performance.

Project Outcome

The completed GMP-compliant laminar airflow system provides localized ISO 5 / Grade A protection for pharmaceutical manufacturing operations in Australia.

Its self-contained design allows pharmaceutical manufacturers to add high-grade airflow protection without major modifications to an existing facility, while the mobile structure provides flexibility for different production workstations.
