Vacuum Baffles have 4 Typical Applications
- Trapping contaminants. As oil, water, selenium, and other contaminants travel in a vacuum system, they will stick to cold surfaces. Cooled baffles provide cold surfaces that can trap the contaminants, thus protecting the process or components from contamination.
- Heat shields. Processes may be hot, yet many vacuum components do not tolerate high temperatures. A baffle will protect cryo-pumps and other components from heat by absorbing the heat load.
- Diffusing gasses. A diffuser controls the movement of gasses in a vacuum system during pump down or venting by changing the speed and direction of moving gasses.
- Moisture Removal. Baffles can be used to increase pumping speeds by removing the moisture (humidity) from the air in the chamber. As cryo-coils and baffles condense the water vapor out of the air, they remove the water vapor load from the pumps and increase pumping speed.
