Enclosure vent planning
Estimate louver and vent free area for sheet-metal panels
Plan louver fields, punched slots, and perforated vent zones for enclosure doors, covers, guards, and airflow panels. Use effective free area to start the RFQ conversation before FortiFab reviews tooling and geometry.

Vent layout notes
The geometric opening area is 24.00 in² inside a 216.00 in² vent field. Estimated pitch is about 9.00 in horizontally and 2.00 in vertically before edge-distance review.
If free area is low
Increase opening count, opening size, or vent field size, or move to a perforated panel pattern with a higher open-area percentage.
What FortiFab reviews
Material thickness, louver tooling, minimum spacing, edge distance, finish direction, deburring, and whether screens or filters restrict airflow.
Planning output only. FortiFab confirms final material, tooling, bend deductions, hardware, tolerances, finishes, and manufacturability during quote review.
