Revolutionizing Cleanroom Safety with Modern Air Shower Systems

What is air shower for clean rooms and why it is needed

Air shower for clean rooms is a specialized closed vestibule located at the entrance (or output) from a clean room. He uses air flows through a HEPA filter supplied by high-speed jets to remove particles from personnel or equipment before entering the controlled area. The air flow effectively “rinses” the pile, dust, fibers and other smallest pollution from clothing or surfaces, preventing them from getting into a supercontrolled clean room.

After the start of the cleaning cycle, the blocked doors guarantee that neither the entrance nor the output will be open until the process is completed, ensuring the tightness between the controlled and uncontrolled zones.

Sharp rise in popularity: HEPA-filtered air, ISO-5 cleanrooms, tunnel airlocks

In recent years, three terms have become key factors in cleanroom design and marketing:

Air purified by a HEPA filter is the basis for effective disinfection. HEPA filters remove particles ≥ 0.3 µm in size with an efficiency of 99.99% and play a key role in ensuring that only purified air enters clean rooms.

ISO-5 Cleanrooms – Characterized by extremely low particle content (Class 100), ISO-5 environments are common in semiconductor manufacturing and biotechnology labs. Airlocks are essential for maintaining these stringent cleanliness standards.

Tunnel airlocks – gaining popularity in high-traffic environments, tunnel designs provide a continuous flow of personnel or equipment. They provide up to 300% greater efficiency than single-seat units, making them a popular choice for intensive production environments.

Benefits for industry: from pollution control to energy savings

Superior Contaminant Control: By removing loose particles before entry, airlocks help maintain the cleanliness of ISO-certified cleanrooms (from ISO-5 to higher) and reduce the load on downstream filters.

Improved product quality: Minimizing particle counts results in fewer defects, especially in sensitive areas such as semiconductor manufacturing, pharmaceuticals and life sciences.

Increased regulatory compliance: Many industries must strictly adhere to ISO or GMP standards, and airlocks help ensure compliance at entry points where the potential for violations is highest.

Cost savings: Pre-treatment extends the life of cleanroom primary HEPA/ULPA filters and reduces energy consumption, resulting in long-term efficiency gains.

Innovation in design and adaptation to customer needs

Modern airlock solutions are adaptable to various enterprise needs:

Configurations: Single, multi-space and tunnel airlocks are available to provide continuous productivity and operational efficiency.

Cycle Optimization: Typical cleaning cycles include 4-8 seconds of high velocity air purge followed by 2-4 seconds of purge controlled by microprocessors and indicator lights.

Materials and special features: Options range from stainless steel and powder-coated steel to low-profile designs for low-ceilinged spaces. Features like ionizers, UV sterilization, ADA compliance, and customizable doors add versatility.

Case Study: Scaling Cleanroom Access Paths

Imagine a semiconductor factory moving from manual dressing to automated workflows. Installing tunnel airlocks designed to handle dozens of workers per minute ensures no reduction in contamination while significantly increasing productivity and reducing bottlenecks.

At the same time, small biotechnological laboratories or manufacturers of medical devices that turn to the ISO-5 clean premises can use compact single installations, which are still guaranteed to ensure the effectiveness of HEPA air-filtration and compliance with regulatory requirements-and all this with the minimum occupied area.

The final conclusion

Air shower for clean rooms can remain unnoticed, but he is an unprepared hero in responsible production and research. In connection with the growing requirements for controlling pollution and operational efficiency, keywords such as HEPA air filtration, pure ISO-5 and tunnel air souls should remain in the spotlight for any discussion (or search) of innovation in the field of clean environment.
