Types of Commercial Kitchen Hoods
Commercial kitchen hoods vary based on the type of contaminants they are designed to handle. Understanding these differences ensures proper hood selection for safety, ventilation, and code compliance. Key hood types focus on grease-laden vapors, steam, and other exhaust products.
Type I Hood Overview
Type I hoods are designed to capture and contain grease, smoke, and heat produced by cooking appliances such as fryers, grills, and ovens. These grease hoods are equipped with fire suppression systems and grease filters to reduce fire hazards.
They must comply with NFPA96 kitchen compliance standards. The design includes a grease collection system to prevent buildup that can become a fire risk. Regular cleaning is essential to maintain efficiency and avoid failed inspections.
If your kitchen uses high-heat or grease-producing equipment, a Type I hood is required by code. Southern Kitchen Services can help ensure your Type I hoods receive thorough cleaning and maintenance tailored to your Middle Tennessee location.
Type II Hood Overview
Type II hoods handle heat and steam, but are not intended for grease removal. They are typically installed over sinks, dishwashers, and ovens without grease emissions. These hoods focus on reducing moisture and odors while maintaining proper airflow.
Unlike Type I hoods, Type II hoods do not require fire suppression systems but must still adhere to ventilation standards. They help prevent excess humidity, which can cause damage or discomfort in your kitchen environment.
Maintaining Type II hoods involves routine cleaning to remove mineral deposits and ensure filters remain effective. This supports better air quality and extends equipment lifespan in kitchens across Nashville, Brentwood, and surrounding areas.
Condensate Hoods
Condensate hoods specifically target steam and water vapor generated during cooking processes such as boiling or steaming. They are designed to condense vapor and prevent it from entering the ventilation system, protecting ductwork and fans from moisture damage.
These hoods reduce corrosion and the buildup of grease mixed with water, which is harder to clean. Proper installation and cleaning are critical to avoid mold and maintain air quality.
Condensate hoods are useful additions where steam generation is significant, helping you maintain safer and more efficient operations. For expert cleaning and maintenance of commercial kitchen exhaust hoods, including condensate systems, rely on Southern Kitchen Services in Middle Tennessee.

Technical Specifications and Sizing
When selecting a commercial kitchen hood system, understanding the airflow capacity, size requirements, and noise control is critical. Proper sizing and technical details ensure effective removal of heat, smoke, and grease, while meeting safety standards and operational needs.
CFM Rating and Airflow
CFM (cubic feet per minute) rating measures the volume of air your exhaust hood can move per minute. This rating should match your kitchen’s cooking equipment to effectively capture contaminants and heat.
Higher CFM ratings are needed for high-heat or grease-producing appliances, such as charbroilers or fryers. Undersized hoods with insufficient airflow lead to poor ventilation, increased fire risks, and potential code violations.
Your hood’s exhaust fan and makeup air system must balance the CFM to maintain proper airflow and avoid negative pressure in the kitchen. Consulting professionals, like Southern Kitchen Services, can help calculate the exact CFM based on your kitchen layout and equipment.
Sizing Guidelines
The hood must cover the entire cooking surface plus extend beyond it to capture all rising smoke and grease. A good rule of thumb is for the hood width to be at least equal to the combined width of the cooking equipment, with a recommended 6 to 12 inches of overhang on each side.
Hood heights and depths vary, but compliance with local codes and NFPA96 standards is non-negotiable. Proper sizing also considers ceiling height and ventilation duct dimensions to optimize airflow efficiency.
When sizing your commercial kitchen exhaust hood, take into account the type of cooking, kitchen configuration, and maintenance access. Reliable contractors in Middle Tennessee, familiar with these parameters, can ensure your system meets all safety and performance specs.
Noise and Filtration
Noise levels from commercial kitchen hoods come primarily from exhaust fans and airflow turbulence. Choosing models with sound-reducing designs and vibration isolation can protect kitchen staff from excessive noise exposure.
Filtration is equally important to trap grease and airborne particles before they enter the ductwork. Use grease filters designed for easy cleaning and replacement to maintain optimal performance and fire safety.
Proper filtration reduces buildup inside ducts, lowering fire hazards and cleaning frequency. Regular maintenance, such as the detailed hood and exhaust cleaning services offered by Southern Kitchen Services in Brentwood and Nashville, supports system longevity and kitchen safety.

System Components and Integration
A commercial kitchen hood system relies on several crucial parts working together to ensure effective ventilation, fire safety, and regulatory compliance. Each component must be properly installed and maintained to keep your kitchen safe and efficient.
Grease Duct and Ductwork
The grease duct is a specialized conduit designed to safely carry grease-laden vapors from cooking appliances to the exhaust system. It is typically constructed from stainless steel to resist corrosion and fire hazards.
Ductwork must be sealed and insulated correctly to prevent grease accumulation, which can increase fire risk. Frequent cleaning is essential since grease buildup obstructs airflow and violates NFPA96 kitchen compliance.
Proper design ensures smooth airflow without excessive bends, which can trap grease. Regular inspections and maintenance by companies like Southern Kitchen Services can help maintain duct integrity and reduce fire risks in your commercial kitchen.
Exhaust Fans
Exhaust fans are responsible for pulling contaminated air through the hood and duct system, expelling heat, smoke, and grease vapors outside. Their capacity must match kitchen demands; an undersized fan will reduce efficiency, while an oversized one wastes energy.
You should use fans made of corrosion-resistant materials and reliable motors that maintain steady airflow. Variable speed controls can optimize performance, conserving energy during slower kitchen periods.
Mounting location matters—roof-mounted fans minimize noise inside, while inline fans offer easier maintenance. Proper fan operation supports a compliant kitchen hood system and helps your establishment pass inspections, especially in areas like Nashville or Brentwood TN.
Controls and Automation
Controls manage the entire hood system’s operation, including fan speeds, lighting, and fire suppression activation. Automated systems improve safety by responding quickly to grease fires and regulating airflow based on kitchen activity.
Demand-controlled ventilation systems reduce energy costs by adjusting fan speed using heat, smoke, or occupancy sensors. This ensures efficient ventilation without wasting power during downtime.
Fire suppression controls integrate with hood components to activate extinguishing agents promptly when needed. Your system should feature user-friendly interfaces for quick manual overrides during emergencies. Incorporating these technologies helps maintain safer, code-compliant kitchens across Middle Tennessee.
Utility Distribution Systems
Utility distribution encompasses the delivery of electricity, gas, water, and other services essential to hood operation. Proper layout minimizes congestion and risk, ensuring that utilities do not interfere with ventilation components.
Gas lines must be installed separately from electrical wiring to avoid hazards. Water supplies for hood wash-downs or fire suppression systems require durable piping that resists corrosion and leakage.
Clear labeling and easy access for maintenance reduce downtime and improve safety. Coordinated utility integration, combined with regular inspections by specialized providers, supports overall kitchen hygiene and operational reliability in busy commercial environments.
