Airlocks are used in a variety of applications, primarily to prevent contamination or maintain air pressure in a controlled environment. They are essentially a small chamber with two doors that act as a barrier between two different environments.
Here are some common applications of airlocks:
- Cleanrooms: Airlocks are essential in cleanrooms, such as those used in the pharmaceutical industry, to prevent the entry of dust, particles, and other contaminants. This helps to maintain the sterile environment required for manufacturing sensitive products. [Source: "3 Types of Airlocks and its Purpose and applications"]
- Submarines and underwater facilities: Airlocks are used in submarines and underwater facilities to prevent water from entering when personnel or equipment need to pass between the interior and exterior. [Source: "Airlock - Wikipedia"]
- Spacecraft: Airlocks are used in spacecraft to allow astronauts to exit and re-enter the spacecraft without losing air pressure. They are also used to dispose of waste materials.
- Fermentation: Airlocks are used in fermentation to allow the release of carbon dioxide while preventing the entry of oxygen, which can spoil the product. They are commonly used for brewing beer, making wine, and fermenting pickles and sauerkraut.

- Material handling systems: Rotary airlock valves are used in material handling systems to control the flow of bulk materials, such as powders, granules, and pellets. They are cost-effective and durable, requiring minimal maintenance. [Source: "Used Rotary Airlock Valves, Feeders | Stainless Steel Rotary Valves"]
Airlocks come in various forms and sizes, depending on their purpose and application. They can be as simple as a single chamber with two doors, or more complex, incorporating multiple chambers and specialized equipment for specific requirements.
