For Low Pressure Applications Only! (5 PSI or Less)
SAF Industrial Viewports are available in 3″ or 4″ pipe sizes and mount to a mating flange, with viewing components housed in an NPT threaded body half. The stainless steel slide arrangement in the blast gate provides added protection and extends the life of the lens during operation, allowing for safer maintenance during vessel downtime.
For additional cooling, a purge connection can be added, positioned on either the glass or vessel side of the blast gate housing. The standard purge is located at the 3 o’clock position, with alternative placements available upon request.
