Picking the right system needs you to know how these units work and what they do in your kitchen. To find the best setup, you must first know what the parts do. The path begins with What Are Commercial Kitchen Ventilation Hoods.

What Are Commercial Kitchen Ventilation Hoods?

Commercial kitchen ventilation hoods are the core of any safe food service space. These systems sit above cooking gear to pull out heat, smoke, and grease. A fan draws air through the hood and ductwork to move it outside. This process keeps the air clean and safe for your staff and guests. At AirSupply, we offer Type C ventilation hoods in sizes from 4 to 12 feet to fit your layout.

How Commercial Kitchen Hoods Work

The system works by creating a constant flow of air. As you cook, the hood captures rising heat and smoke. A powerful fan pulls this air through grease filters and into the duct system. Once inside the ducts, the air travels to a vent on the roof or wall. This displaced air must be replaced with fresh air to keep the pressure balanced. Most systems use a make-up air unit to bring in outside air so the kitchen does not become a vacuum.

Proper sizing is key for the system to work well. The hood must extend at least 6 inches past your cooking line on all sides. Also, the bottom edge should be no more than 4 feet above the cooking surface. You can follow guides from the National Fire Protection Association to ensure your setup meets safety codes. These rules help stop grease from building up and causing fires.

Main Types of Ventilation Hoods

There are two primary types of hoods used in commercial kitchens. Each one serves a different purpose based on what you cook. Type I hoods are built for heavy-duty tasks like grilling or frying. They handle grease and smoke, so they must have a fire suppression system. These hoods use baffle filters to trap grease before it enters the ductwork. This is the standard choice for most restaurant and food truck owners who use ranges or fryers.

Type II hoods handle heat, steam, and odors but not grease. You will often see them over dishwashers or steam tables. Since they do not deal with grease, they do not need fire suppression or grease filters. Choosing the right type depends on your local building code and the equipment you use. Our hoods carry a UL 710 listing, which proves they meet high safety standards for commercial use.

Type 1 vs Type 2 Commercial Kitchen Hoods: What Is the Difference?

Choosing the right commercial kitchen ventilation hoods is the first step in building a safe kitchen. You must know the gap between Type 1 and Type 2 systems to follow local fire rules. The main factor is the type of waste your cooking tools create. A Type 1 hood pulls out grease and smoke, while a Type 2 hood handles heat and steam. Picking the wrong unit can lead to costly fines or big fire risks.

Type 1 Hoods for Grease and Smoke

You need a Type 1 hood for any gear that produces grease, smoke, or heavy heat. This group includes tools like char-broilers, fryers, and open-top ranges. These hoods use metal baffle filters to trap oil and grease before they enter your ductwork. Because grease builds up and burns easily, Type 1 hoods must have a self-run fire suppression system. This system acts fast to put out flames and cut off fuel to your cooking line.

Our Type C ventilation hoods are best for these high-heat tasks. They are UL 710 listed, which means they pass tough tests for shop use. These canopy hoods come in sizes from 4 to 12 feet to fit your small kitchen layout. Following clear ventilation design rules ensures your hood pulls enough air to keep the room clear. Most food truck and restaurant owners pick Type 1 hoods to stay safe and meet local health rules. These units are built to handle the thick smoke and high heat of a busy kitchen.

Type 2 Hoods for Heat and Moisture

Type 2 hoods serve a simpler role in your ventilation plan. They remove heat, moisture, and smells from tools that do not create grease. You will usually find these over pro dishwashers, steam tables, and small ovens. Since they only move steam and hot air, they do not need heavy grease filters. They also do not require the costly fire suppression systems used in Type 1 setups.

This gap makes Type 2 hoods cheaper to buy and much easier to set up. But you must never use a Type 2 hood over grease-producing gear. Doing so lets oil build up in your fans and ducts, which creates a big fire risk. Always check with your local fire marshal before you buy any gear. For most food trucks and ghost kitchens, a Type 1 system is the best choice for long-term safety and code rules. Buying the right Type 1 unit now saves you from costly changes later.

Commercial Kitchen Hood Code Requirements and NFPA 96 Compliance

Every commercial kitchen must follow strict safety rules to prevent fires. These rules come from the International Mechanical Code (IMC) and the NFPA 96 standard. Following these codes keeps your staff safe and helps you avoid costly fines. Local authorities often check for a UL 710 listing before they approve a new system.

Key Fire Safety and NFPA 96 Rules

The NFPA 96 standard is the main guide for kitchen fire safety. It sets the rules for how you design and clean your exhaust system. For any equipment that makes grease or smoke, you need a Type 1 hood. These hoods must have a wet chemical fire suppression system. While AirSupply hoods are UL 710 listed for safety, we do not sell the fire systems. You will need to hire a local pro to set up your fire suppression and get it certified.

You must also keep a regular cleaning schedule. Grease buildup in your ducts or fans is a major fire risk. High-volume kitchens often need professional cleaning every month. If you run a smaller shop, you might only need service once per quarter. Most NFPA guidelines focus on keeping grease away from surfaces that can catch fire.

Correct Hood Placement and Sizing

Where you put your hood is just as important as the hood you buy. Most local codes require a six-inch overhang on all sides of your cooking equipment. This extra space helps catch smoke and heat before they escape the room. If your hood is too small, your fans will have to work much harder to keep the air clean.

Height also matters for code compliance. The bottom edge of your hood should be no more than four feet above your cooking surface. If you go higher, the oily air will cool down and settle before it hits the filters. You can check your specific needs using our Type C ventilation hoods sizing tools. Following these mounting rules ensures your system works as intended by the maker.

Make-up Air and Duct Requirements

When you pull air out of your kitchen, you must put new air back in. This is called make-up air (MUA). Most building codes require MUA systems to replace about 80% to 90% of the air you exhaust. Without it, your kitchen will develop low pressure. This can make doors hard to open and cause your exhaust fans to fail early. You can find compatible make-up air units to keep your air pressure balanced.

Your ductwork must also meet specific code rules. All ducts must be grease-tight and made of thick steel. Most inspectors look for welded or riveted seams that prevent grease leaks. If your ducts leak, grease can build up in your walls and ceilings, creating a hidden fire path. Always verify your duct plan with your local fire marshal before you start your installation work.

How to Size a Commercial Kitchen Ventilation Hood

Getting the right size for your hood is the most vital part of your setup. A hood that is too small will let smoke and heat fill your kitchen. One that is too big will waste energy and pull out too much air. You can find the best fit by following a few clear steps.

Check your cooking line

First, you must measure the width and depth of your cooking gear. Your hood needs to cover every unit that makes smoke or grease. Most local codes follow NFPA 96 standards for safe kitchen design. These rules help stop fires and keep air clean.

Your hood must extend at least 6 inches past your gear on each side. This means if your stove is 48 inches wide, your hood should be 60 inches wide. This extra space helps catch smoke that drifts to the side as it rises. For more gear, look at our Type C ventilation hoods which come in 4 to 12 foot lengths.

Find your air flow

Next, you need to find the right cubic feet per minute (CFM) for your fan. CFM is how much air your fan moves each minute. For a wall-mounted hood, you usually need 100 to 150 CFM for every foot of hood length. Heavy cooking like woks may need 50% to 100% more air flow to stay safe.

The total CFM depends on the size of the hood opening and what you cook. You can use free sizing calculators to get the exact math for your shop. Getting this right helps you pick the best commercial kitchen exhaust fans for your needs.

Follow these sizing steps

1. Measure your cooking line width and add 12 inches total for the needed 6-inch side overhang.
2. Check the vertical gap between your cooking surface and the hood, which should be 4 feet or less.
3. Find your CFM need by multiplying your hood length by the air flow rate for your unit type.
4. Choose an upblast fan that matches your CFM, such as our 2050, 2500, or 4000 CFM models.
5. Plan for make-up air to replace the air your fan pulls out of the building.

Choose your fan and air supply

Once you know your CFM, you can pick your fan. We offer fans for different needs, from a 2050 CFM model for $550 to a 4000 CFM model for $750. These fans sit on your roof and pull air up and out. This keeps your kitchen cool and cuts down on grease buildup.

You must also replace the air you exhaust. This is called make-up air. If you do not add new air, your fan will struggle to pull air out. This can cause doors to stick or lead to back-drafts from other gas units. Most shops need a supply unit that gives about 80% to 90% of the exhaust flow.

What Does a Commercial Kitchen Hood System Cost?

Buying a new exhaust system is a big cost for any food business. Prices vary based on how you buy the gear. You can buy a pre-built bundle or choose a component-based setup. Most owners find that buying parts on their own saves thousands of dollars in costs. National rules like NFPA 96 set the law for how these units must work, but they do not set the price.

Component Pricing vs Integrated Bundles

Most big brands sell bundled sets. These packs include the hood, fan, and air units in one crate. While easy to buy, these sets often cost between $2,259 and $7,399 for common sizes. Some high-end brands charge $20,000 or more for large units. These high prices often include a markup for the ease of a single item. But you can save a lot by picking only the parts you need for your specific kitchen layout.

AirSupply offers a new path by selling single parts. A full DIY system with a hood and fan can start near $900. This way lets you skip the high cost of pre-built sets. By matching a Type C ventilation hood with the right fan, you can get a code-safe setup for 60% to 70% less. This is a great choice for food trucks or small shops with tight budgets.

Commercial Ventilation Cost Comparison

Comparing brands helps you see the price gap. Some sellers focus on high-end work, while others serve budget-minded DIY shops. Local building codes from the International Mechanical Code apply to all systems no matter the price. You must ensure your setup meets these rules to pass checks and stay safe from grease fires.

Brand	System Type	Price Range	Best For
AirSupply	Component-Based	$900 - $3,000	Food Trucks & Small Kitchens
WebstaurantStore	Integrated Bundles	$2,259 - $7,399	Standard Restaurants
HoodMart	Factory Direct	$2,000 - $20,000+	Custom Layouts
Premium Installers	Full Turnkey	$5,000+	High-Volume Dining

Shipping and Financing Options

The sticker price is not the only cost to think about. Shipping a heavy hood can cost hundreds of dollars. Many sellers add this fee at the end of the sale. AirSupply provides free shipping to the main US states to keep costs low. For those who want to save cash flow, loans are also a choice. You can get a commercial kitchen exhaust fan and hood with 0% APR and low monthly fees.

Hood, Fan, and Make-Up Air: Key Components of a Complete System

A full commercial kitchen ventilation system works like a machine with many parts. Each part must work well for the whole system to clear smoke and heat. At AirSupply, we sell these parts individually across six collections. This lets you buy only what you need without paying for extras. A basic setup includes the hood canopy, an exhaust fan, a make-up air unit, and ductwork.

Exhaust Fans: The Engine of Your System

The exhaust fan is the heart of your kitchen ventilation. It pulls hot air, smoke, and grease out of the building. We offer three main upblast fan models to fit different kitchen sizes. Our 2050 CFM fan costs $550, while the 2500 CFM model is $650. For larger kitchens, our 4000 CFM fan is $750. These commercial kitchen exhaust fans sit on your roof to blow air up and away from your building.

Choosing the right fan depends on your hood size and what you cook. Heavy cooking like grilling or frying needs more power than simple ovens. You can use our free fan sizing tool to find the best match. Using the right fan helps you meet NFPA 96 standards for grease removal and fire safety. Getting this right prevents grease buildup, which is the top cause of kitchen fires.

Make-Up Air Units: Balancing Air Pressure

When you pull air out of a kitchen, you must put new air back in. This is what make-up air units do for your shop. Without new air, your kitchen gets "negative pressure." This makes doors hard to open and can pull bad smells back inside. Most codes require new air to replace about 80% to 90% of what you exhaust.

We sell make-up air units separately to keep your costs low. Many big brands force you to buy them in a high-priced package. By selling parts one by one, we help you save 60% to 70% compared to bundled sets. This is very helpful for food truck owners who have limited space and tight budgets. Our units help keep your kitchen air fresh and your gas appliances working safe.

Ductwork and Accessories: Completing the Installation

Ductwork is the set of pipes that carries air from the hood to the fan. It must be grease-tight to prevent leaks and fire risks. We stock ductwork components like stainless steel pipes and elbows. You will also need accessories like grease filters and grease traps to keep the system clean. These parts ensure your Type C ventilation hoods work at their best.

Buying parts individually gives you more control over your layout. You can pick the exact duct lengths and fan power for your specific building. This flexibility is a big plus for ghost kitchens or odd-shaped restaurant spaces. Our team offers free advice to help you pick the right mix of parts. This ensures you get a complete, safe system for about $900 in total materials.

Commercial Kitchen Hood Maintenance and Cleaning Schedules

Commercial kitchen ventilation hoods need regular care to stay safe and run well. Grease buildup is the main cause of fires in food service shops. When fat and oil collect in the ducts, a single spark can start a large fire. Keeping your system clean helps your gear last longer and keeps your staff safe. Proper upkeep also prevents foul odors from spreading to your dining area.

NFPA 96 Cleaning Frequency Guidelines

The NFPA 96 code sets the rules for how often you must clean your hood system. These rules depend on how much you cook and the type of fuel you use. Most local fire codes follow these standards to prevent grease fires. Proper care ensures you stay in line with safety laws. You should keep a log of all service dates to show to fire inspectors.

• High-volume shops that cook 24 hours a day need a monthly cleaning schedule to manage heavy grease.
• Moderate-volume kitchens usually need an expert cleaning every three months to stay code-compliant.
• Low-volume sites, such as small shops or seasonal stands, only need service twice a year.
• Solid fuel cooking, such as charcoal or wood, requires a monthly check and cleaning even if you cook less.

Baffle Filter Maintenance

Your hood filters are the first line of defense against grease. Baffle filters trap oil before it enters the ductwork. You should wash these filters daily or weekly based on how much grease you produce. Many chefs run them through the dishwasher at the end of every shift. Dirty filters block airflow and force your fan to work harder, which can lead to higher power bills. You can find new filters and ventilation accessories to keep your setup in top shape.

In addition to filters, you must check your grease traps and cups often. These parts catch the oil that the baffles drain away. If the cup overflows, grease will leak onto your cooking surfaces or the floor. Emptying these traps daily is a simple way to reduce fire risks and keep your kitchen clean. You should also check the roof fan for grease pools that could damage your roof shingles.

Signs Your Hood Needs Cleaning

It is vital to spot the signs of a dirty system before a fire starts. If your kitchen stays smoky or smells like old oil, your hood may be clogged. You might also see grease dripping from the hood edges or the fan housing. A loud or rattling fan often means the motor is struggling with heavy buildup. If you notice these issues, call an expert to inspect your system right away. Regular checks will save you money on costly repairs later.

Choosing the Right Ventilation Hood for Your Kitchen

Picking the best hood for your kitchen depends on what you cook and how much space you have. You must also think about your budget and local fire rules. Most commercial kitchen ventilation hoods catch grease, smoke, or steam. If you use fryers or grills, you need a Type 1 hood to handle heavy oils. For ovens that only make steam, a Type 2 hood is enough. Choosing the right style helps you save money and keep your air clean. Our component model works for all shops because you only pay for the parts you need.

Price is a big factor for most new owners. Big brands like WebstaurantStore sell Halifax bundles for $2,259 to $7,399. These kits often cost much more than buying parts one by one. HoodMart also sells factory-direct hoods that can cost over $20,000 for large sites. By picking your own fan and hood, you can save 60% to 70% on your total cost. This path gives you more control while keeping your startup costs low. You can buy the hood now and add the make-up air unit later as your budget grows.

For Food Truck Operators

Food trucks have very little room for large gear. If you run a truck, you need a compact system that fits into a small space. Most trucks use a 4-foot or 6-foot hood to save on weight. You still need a Type 1 hood if you cook with oil or gas to meet fire safety rules. A basic setup with a hood and a small fan often costs between $1,500 and $3,000.

This price is much lower than the high-cost bundles sold by big dealers. Buying only the parts you need helps you stay within your tight budget. You should also check that your hood has a 6-inch overhang to catch all smoke.

For Independent Restaurant Owners

Small to medium restaurants often have 10 to 100 seats. Your needs will change based on your menu and how many stoves you use. Most owners in this group spend between $3,000 and $8,000 on a full setup. You should look for a system that can grow if you add more gear later.

Our commercial kitchen exhaust fans come in three sizes to match your hood length. A 2500 CFM fan is a common choice for a standard cooking line. This modular plan saves you money compared to pre-set kits from HoodMart or Halifax. It also makes it easy to swap parts if your menu changes.

For Ghost Kitchen Operators

Ghost kitchens focus on high output and fast delivery. Since these kitchens often have many stations, modular hoods work best. You can set up many small hoods to handle different types of food at the same time. This layout makes it easy to change your kitchen as your business grows. Fire risk is a top concern when you cook all day long.

The National Institute for Occupational Safety and Health notes that grease buildup is a leading cause of fires in food service. Using separate fans for each hood can help you manage air flow and lower your risk. You can also add more fans as you add more cooking stations.

No matter which group you fall into, the goal is to get a safe system that fits your shop. For a deeper look at sizing, see our guide on how to calculate CFM for your kitchen hood. AirSupply helps you avoid high costs by selling each part on its own. You only pay for the hood, fan, and ductwork that your space needs. This path keeps your costs low while still meeting all UL 710 safety standards. Always check with your local fire marshal to ensure your plan meets all local rules before you buy. This ensures you do not waste money on gear that will not pass a test.

Frequently Asked Questions

Are commercial air hoods needed for all food trucks?

Yes, you usually need a Type I hood if your food truck has gear that makes grease or smoke. Most local laws also require these hoods to have a fire safety system. Food truck owners often pick small hoods that meet safety rules to save space. As stated in industry code guides, your setup should also have a fan to move air and keep the kitchen safe from fire.

Can I use a home range hood in a commercial kitchen?

You cannot use a home hood in a business kitchen because it lacks the strength and fire safety features needed for code. Business kitchens must follow strict fire rules that require heavy steel and special filters. Using a home unit can cause you to fail inspections or start a fire. It is better to buy low-cost business parts that offer real protection for less money than the expensive kits sold by other brands.

Should my make-up air unit be the same size as my exhaust fan?

Your make-up air unit does not need to be the exact same size as your fan. It should replace about 80% to 90% of the air your fan pulls out. This mix stops air pressure problems that can make doors hard to open or pull smoke back inside. You can use a free make-up air tool to find the right size for your fan and kitchen layout.

How far should a hood hang over my cooking gear?

Your hood must hang at least 6 inches past your cooking gear on all sides to meet local laws. This extra space helps the hood catch all the grease and smoke before they fill the room. If you use heavy grills, you may need even more space or a stronger fan to keep the air clean. Proper sizing is a key part of staying safe and following fire rules in any busy kitchen.
