The Fundamentals of Ventilation in Commercial Kitchen

June 13, 2024

Types of Ventilation Equipment

The central piece of any commercial kitchen ventilation system is the exhaust hood. Besides capturing heat, smoke, and grease-laden vapors, they also help control fire hazards. Commercial exhaust fans complement the hood, expelling the captured heat and vapor outside the building.

Makeup air units offer another essential component, replacing the expelled air to balance air pressure and maintain air quality. Fire suppression systems are integral too to handle any potential fire breakouts.

Equipment Selection and Design

When it comes to choosing ventilation equipment, capacity is key. Factors such as cooking equipment type (electric or gas), size, and heat output influence the capacity needed. Equipment should meet National Fire Protection Association (NFPA) standards, ensuring safety.

Layout and design of the kitchen also impact the ventilation system design. Exhaust hoods, for example, must extend 6 inches beyond the cooking equipment on all sides as per NFPA guidelines.

Installation and Maintenance

Professional installation is essential for ensuring the effectiveness and safety of your ventilation system. Depending on your local guidelines, you may need approval from local buildings or health departments.

Regular cleaning is necessary for the ventilation system's proper functioning, keeping them free from accumulated grease. Regular maintenance checks to ensure that all components, especially the fire suppression system, are functioning correctly are vital. In general, a professional inspection every six months should suffice.

Remember, a well-planned and maintained ventilation system contributes significantly to a restaurant's success, ensuring a comfortable cooking environment, limiting fire hazards, and keeping the staff and customers safe. It's an investment that pays back, making it both a safety and business necessity.
