Viewport shutters are used to protect the viewport glass from the inside. This is usually because the process within the chamber involves deposition of material which would otherwise slowly reduce the transparency of the glass and make it difficult to observe the inside of the chamber. On occasion it might also be desirable to protect the user from light inside the chamber, however other solutions such as leaded glass covers exist in order to protect against X-Rays for example.

When choosing your shutter, please take account that the non-venetian type needs more space to open towards the interior of the chamber. For this reason the venetian type may be preferable in certain applications. The venetian type is however not available in smaller sizes due to the space required for the mechanism.

Key Features

• A range of sizes available from DN40CF to DN160CF for the standard type
• DN100CF and DN160CF sizes for the venetian type
• Manual operation (stepper motor or pneumatic with optional limit switches by special request for the standard shutter type, manual-only for venetian type)
• 304L stainless steel (316LN by special request)
• Maximum bakeout temperature 230ºC
