Cleanroom Terminology: What Is an Airlock?

Cleanroom Terminology: What Is an Airlock?

When entering the world of cleanroom design, many people are overwhelmed by the new vocabulary, which can be quite complicated. Suddenly, you have to understand classifications and all sorts of design features and figure out which are right for your application. 

We’re here to break down one of the most common terms you’ll hear in cleanroom design – airlocks. So, what is an airlock, and how does an airlock work? Let’s get jump in.

What Is an Airlock?

An airlock is a system of two doors that are electronically interlocked so that both cannot be opened at the same time. This prevents contamination and prevents particles from outside the cleanroom from entering the cleanroom when personnel enter or exit the cleanroom. 

In addition to its role in contamination control, airlocks can serve as security features, controlling and monitoring access to the cleanroom. An airlock system will also help maintain the controlled temperature of a cleanroom space. They are vital components in various industries, adapting to specific cleanroom requirements while offering emergency features to ensure personnel safety.

How Does an Airlock Work?

An airlock creates a controlled, enclosed space with two interlocked doors. They make a controlled transitional space between an external environment and a cleanroom, with the primary goal of preventing contamination, maintaining cleanliness, and preserving the specified environmental conditions within the cleanroom.

Here’s how airlocks typically operate:

  • Two-Door System: An airlock consists of two doors, one leading to the outside environment and the other to the cleanroom. These doors are electronically interlocked, ensuring that both doors cannot be opened simultaneously.
  • Pressure Differential: The cleanroom typically operates at a higher pressure than the surrounding area. When personnel need to enter or exit the cleanroom, they first enter the airlock. The outer door is closed behind them, sealing off the outside environment.
  • Controlled Environment: Once inside the airlock, the system may initiate a series of processes to maintain the controlled environment. This can include adjusting temperature, humidity, and pressure levels to match the cleanroom’s specifications.
  • Personnel Procedures: Personnel inside the airlock may need to follow specific procedures, such as donning cleanroom attire, which includes specialized garments, headgear, and shoe covers. 
  • Interlocking Doors: After the necessary preparations and checks are completed inside the airlock, the inner door can be opened. This allows personnel to enter the cleanroom while ensuring that the outer door remains closed, maintaining the pressure and cleanliness of the cleanroom.
  • Security Features: Some airlocks include security features like access control systems to authenticate and authorize individuals. 

What Kinds of Airlocks Are There?

There are two types of airlocks: secure and non-secure airlocks. In a secure airlock system, all doors remain locked until a request to enter is granted. This generally occurs through a “request to enter device,” like a button or keypad. A non-secure airlock means that the doors remain unlocked until the first door is opened; then, the other doors lock.

You also have the option of making your airlocks supervised or unsupervised. For high-security areas, you may have a supervised airlock, where personnel must press a “request to access” button. The request must be approved via a CCTV or viewing panel verification system. 

An unsupervised cleanroom could control access through a biometric reader or keypad to gain access. Such systems are useful where only authorized personnel may enter the cleanroom environment.  

Enhancing Cleanroom and Airlock Security

Depending on the classification and application of your cleanroom, you might want additional security features in place on your airlock. These considerations aim to enhance security and monitoring within the airlock system to minimize the risk of contamination and maintain the pristine conditions of the cleanroom.

  • Breach Alarms: Depending on the sensitivity and cleanliness requirements of the cleanroom, it may be essential to implement breach alarms within the airlock system. These alarms serve as a critical safeguard, alerting personnel when the airlock has been breached. Breach alarms are triggered when unauthorized access or contamination may have occurred. 
  • Door Open Duration Alarms: Cleanrooms often require swift and controlled access, and extended open-door times can compromise the cleanliness and environmental conditions. Door open duration alarms provide a mechanism to ensure that doors are not left open for too long, thereby preventing prolonged exposure of the cleanroom to the outside environment.
  • Door Status Indicators: Door status indicators are visual or electronic displays that provide real-time information about the current state of the airlock doors. These indicators offer a quick and easy way for personnel to confirm whether the outer door is securely closed before opening the inner door.

Building a battery dry room

Building a battery dry room

Many materials and processes used in battery production are susceptible to moisture damage. For that reason, humidity control is critical in a battery dry room. The experts at Angstrom Technology can create a stable low dewpoint production environment to meet your requirements. In this blog post, we explain how.


Battery dry room construction

Battery dry rooms require a constant supply of ultra-dry air to create and maintain low-humidity conditions for the R&D and production of solid-state and lithium-ion batteries.

We can develop an energy-efficient dry room to protect your critical process in any of the following applications. We do this by combining airtight envelope systems, dehumidification systems, and HVAC design.

Battery dry room manufacturers

As battery dry room facility manufacturers, we deliver complete dry room systems. Working with specialist humidity control partners, we provide bespoke solutions that include industry-leading energy-efficient HVAC systems.

A typical clean room environment operates at 20.0°Cdb, 50% Relative Humidity — which is a dewpoint of 9.3°Cdp. Due to the materials’ sensitivity in the process, solid-state battery dry rooms can require control to minus 40.0°Cdp at the room’s exit point. A lower dewpoint of minus 50.0°Cdp is required for Lithium-ion battery dry rooms, and the next generation may have even tighter requirements. The battery chemistry may need the environment to reach minus 80.0°Cdp at the point of supply into critical areas, such as Electrolyte Fill.

Post-and-Panel vs. Seamless Cleanroom Wall Systems

Post-and-Panel vs. Seamless Cleanroom Wall Systems

The materials you use to build your cleanroom have a lasting impact on its cleanliness, performance, durability, and appearance. Arguably the most important of these materials is the cleanroom wall system you choose. 

Let’s take a look at two of the most common types of cleanroom wall systems: post-and-panel and seamless. 

Post-and-Panel vs. Seamless Wall Systems: What’s the Difference?

First, some definitions. Learn more about what post-and-panel and seamless wall systems are, and how they differ below. 

What Is a Post-and-Panel Cleanroom Wall System?

A post-and-panel cleanroom wall system utilizes a series of non-progressive posts and panels that are joined together to create a modular enclosure. The posts and panels are “stitched” together with a corrugated roof deck that keeps them in place. 

The end result? A modular enclosure that’s self-supporting, reconfigurable, and isolated from its surrounding environment. It stands alone and is separate from the existing building structure. 

What Is a Seamless Cleanroom Wall System?

A seamless cleanroom wall system utilizes studless, flush wall or liner panels to create a modular enclosure. These wall panels can be either progressive or non-progressive but are tightly sealed so that no seams are exposed. They also have coving (a curved covering that connects a wall to a ceiling) on both horizontal and vertical intersections. 

A seamless cleanroom wall system can be tied into steel stud walls and/or the existing building structure that surrounds it. It also typically features a flush, walkable ceiling. Its seamless design allows for durable performance and sleek aesthetic appeal for the most stringent applications. 

Pros & Cons of Post-and-Panel Cleanroom Wall Systems

Now let’s take a look at some of the advantages and disadvantages of these cleanroom wall systems, specifically highlighting distinguishing factors between each type. We’ll start with post-and-panel. 

The main advantages of post-and-panel cleanroom wall systems are: 

  • They can be reconfigured easily. Due to their non-progressive nature, post-and-panel wall systems are the easiest type to reconfigure. The-two piece stud post allows removal and replacement of a wall panel without disturbing adjacent panels. They also accomodate quick and easy vertical installation of electrical, data, and communication lines in the raceways, which are accessible from the removable cover plate. If your facility is expecting growth or changes in the future, this is an important benefit to consider. 
  • They’re self-supporting. Post-and-panel wall systems can stand alone. The structural-grade, extruded aluminum acts as a structural column on spaces with long clear spans or load bearing roofs. The stud system will accommodate steel tube inserts for additional load bearing capability. They don’t need to be integrated into an existing building structure, giving you a bit more versatility with placement and layout. 

The main disadvantages of post-and-panel cleanroom wall systems are: 

  • They’re harder to clean. Because they’re not fully seamless (the panels will fit within studs creating an ⅛” protrussion or less) and have no coving integrated into their system, post-and-panel wall systems can be more difficult to clean. There are more seams and crevices where particles can accumulate. 
  • They’re not FM-approved. Post-and-panel wall systems are Class A non-combustible, but they’re not FM-approved. This may be a deal breaker for certain applications, depending on industry-specific requirements. 

Pros & Cons of Seamless Cleanroom Wall Systems

Now for some advantages and disadvantages of seamless cleanroom wall systems — which are basically the opposite of what we mentioned about their post-and-panel counterparts. 

To start, the main advantages of seamless cleanroom wall systems are: 

  • They’re easy to clean. Seamless wall systems have tight, chemically cold-welded uPVC seams and coves so there are no crevices for contaminants to build up in or air leakage. This makes them much easier to clean, wash down, and fumigate. For higher ISO classifications with stringent cleaning requirements, this is the best option.
  • They feature a floating flush ceiling. Their floating flush ceiling offers the same fine line seams and finishes as the modular wall system. The flush ceiling platform utilizes 5’ x 10’ ceiling panels and 5’ x 10’ hanger spacing, allowing the installation of FFUs and lights without changing the ceiling panel orientation. Interior wall panels are attached to the bottom surface of the ceiling panels and wall/ceiling covings can be run at any location making it integral to the cleanroom system. The walkable ceiling is capable of supporting a wide variety of mechanical systems and accommodating components and small equipment.
  • They’re FM-approved. Seamless wall systems are both Class A non-combustible and FM-approved, meaning they offer the considerable level of fire resistance that some cleanroom applications require. 

The main disadvantages of seamless cleanroom wall panels are:

  • They’re not as easy to reconfigure. While it’s definitely not an impossible task, reconfiguring a seamless cleanroom is a bit more difficult. This is especially true if it’s built with progressive wall panels where replacement is done through the use of rotating splines.
  • They can’t stand alone. Seamless cleanroom wall systems aren’t self-supporting. They must tie into the existing building structure, or you’ll have to build a steel superstructure for support.
  • They’re a bit more expensive. Since the system isn’t structurally sound on its own and must be supported by a steel superstructure or existing building, seamless cleanroom wall systems are generally the more costly option.  

What Type of Wall System Is Best for My Cleanroom?

Both post-and-panel and seamless cleanroom wall systems are great options that can meet varying specifications you need them to, so there’s not really a “wrong” answer to this question. A better way of looking at it is there might be one option that’s better for you than the other. That can vary for you based on a few factors, including:
