Safely protecting system windows during processes
Our viewport shutters provide ideal protection during processes such as vacuum deposition. This is because they come with a 100% full closure option.
Utilising the magnetically coupled MagiDrive rotary feedthroughs for shutter actuation, the range can be actuated manually or pneumatically (where remote control is required).
- Available on CF38 to CF150 flanges
- Manual or pneumatic actuation
- Fully bakeable to 250°C
- Friction control system
- 100% full closure option
- Position switch option
100% full closure actuator
The VPSFC range of viewport shutters provides 100% protection against the coating of viewports in HV and UHV deposition applications. The range is available in either AutoClose, Pneumatic or Pneumatic with position-feedback options.
Viewport shutters can also be fitted with a pneumatically actuated MagiDrive. Used in their simplest form, they could be operated remotely from a control panel or switch. For more sophisticated protection, the pneumatically-actuated MagiDrive could be interlocked to the ‘vacuum process’. In this instance, for example, activating a deposition source would automatically close the viewport shutter. For critical applications, an optional ‘feedback-switch’ assembly can be fitted to the drive. This would confirm to the process controller that the shutter is in the closed position.
