What Does a Complete Commercial Kitchen Ventilation System Include?
A working commercial kitchen ventilation system does more than remove smoke. It manages heat, grease, steam, and odors while supporting fire safety and air quality. A typical system includes:
- Range hoods (exhaust hoods) positioned above cooking equipment to capture and remove smoke, steam, and grease-laden air.
- Ventless hoods that use filters and purification technology to clean air and recirculate it, suitable for locations without external exhaust ducts.
- Fume purification systems that remove grease, odors, and particulates before air is exhausted or recirculated.
- Ductwork, fans, and makeup air systems that move air out of the kitchen and replace it with fresh air to maintain proper pressure and comfort.
The exact combination depends on your cooking equipment, kitchen layout, building structure, and local fire and health codes.
