Challenge briefing
VisuNet Industrial Thin Client is a cleanliness target (ISO 4406 / 8573 / dust class), not a micron sticker. Ingression and cooling decide whether the element lasts.
Write the cleanliness number on the challenge. Size breathers, returns and collectors for ingression, not the pad that was free.

This note is a plant-side briefing, not a substitute for the manufacturer datasheet. When the company claims the FTE profile they can attach official PDFs here.
