How this tool helps
Use this for early commercial kitchen exhaust checks before detailed hood manufacturer selection. The profile applies conservative planning floors to very low capture velocity inputs.
Calculation methodology
Airflow = hood plan area x capture velocity x exposure factor x design margin, with metric area converted to square feet.
Assumptions and limits
This is a planning-level calculator. Final decisions should be checked against approved project standards, local authority requirements, manufacturer data, and qualified engineering review.
