KF Series

The KF Series, also known as Klein Flange or Quick Flange, is another type of vacuum flange system used in high and ultra-high vacuum applications. KF flanges are designed to provide a quick and reliable means of connecting vacuum components while maintaining a good vacuum seal. KF flanges are commonly used in research, laboratory, and industrial settings where moderate vacuum levels are required.

Key features of KF flanges include:

1. Clamp and Seal: KF flanges use a clamping mechanism to secure the connection between two flanges. A circumferential clamp and elastomer O-ring seal are used to create an airtight seal, making assembly and disassembly relatively easy and quick.

2. Flange Size: KF flanges come in a range of sizes, typically designated with KF followed by a number that indicates the flange's nominal inside diameter in millimeters. Common sizes include KF10, KF16, KF25, KF40, and KF50.

3. Common Materials: KF flanges are often made of stainless steel or other suitable materials that are compatible with vacuum systems.

4. Cleanliness: KF flanges are known for their cleanliness and low outgassing properties, making them suitable for applications where contamination of the vacuum chamber is a concern.

5. Ease of Use: The KF system's design allows for relatively simple and fast assembly and disassembly, which can be advantageous in applications where frequent access to the vacuum chamber is required.

KF flanges are widely used in laboratory equipment, thin-film deposition systems, analytical instruments, and other applications where achieving and maintaining a vacuum is essential. They are popular for their ease of use and versatility in creating reliable vacuum connections.
