What the Window Underlayment Does

The viewing window is continually exposed to abrasive particles, dust, and media ricocheting inside the blast cabinet.

The F104-015 underlayment provides a sacrificial protective layer for the viewing window, taking the wear that would otherwise be directed at the window itself.

As the protective material becomes worn or difficult to see through, it can be replaced rather than allowing continued abrasive exposure to damage the underlying window.

Why Window Protection Matters

A clear viewing area isn't just convenient—it allows the operator to see the workpiece and blast pattern while working inside the cabinet.

Worn window protection can result in:

• Cloudy or reduced visibility
• Scratching and abrasive damage
• Difficulty seeing the workpiece
• Increased wear to the underlying viewing window
• More frequent replacement of the permanent window

Keeping fresh protective underlayment installed helps preserve visibility and protects the more expensive cabinet window behind it.

Routine Blast Cabinet Maintenance

Window protection is a consumable maintenance item. How frequently it needs to be changed depends on cabinet usage, abrasive type, blasting pressure, workpiece position, and how much abrasive is directed toward the viewing area.

Keeping a 10-pack on hand makes it easy to replace worn material as needed rather than continuing to operate with poor visibility.
