If you've been searching for a "commercial range hood" or a "restaurant hood" for your kitchen, you're usually after one thing: serious power that clears smoke, steam, and grease the way a professional kitchen does. The good news is that you can get that at home — but a true commercial hood almost certainly isn't what you actually want or need. ROBAM's powerful residential range hoods are engineered to deliver restaurant-grade airflow inside a home kitchen, without any of the cost and complication a commercial system drags along with it.
A commercial kitchen hood is a very different animal from a home range hood. It isn't a single appliance you lift off a shelf — it's an engineered, code-regulated exhaust system built for the sheer volume and fire risk of a foodservice kitchen. Before you spend a dollar, it pays to understand what "commercial" really means, where the line between commercial and residential actually falls, and why a high-CFM wall-mount range hood is usually the smarter, safer choice for a home.
If you cook at home, you almost never need a true commercial hood. A commercial or restaurant hood is a grease-rated exhaust system — welded stainless steel, roof-mounted fans, make-up air, and automatic fire suppression — designed for restaurants and governed by codes like NFPA 96. What a serious home cook actually needs is a residential range hood with commercial-grade airflow, typically 600 to 1,400 CFM for high-heat and wok cooking. The rest of this guide explains exactly what separates the two, how commercial systems are sized and regulated, and how to get that restaurant-level power in your own kitchen.
What Is a Commercial Kitchen Hood?
A commercial kitchen hood — also called a commercial exhaust hood, a commercial vent hood, or a commercial kitchen vent hood — is the stainless-steel canopy that captures heat, smoke, grease, and steam over a restaurant's cooking line. But the hood itself is only the visible piece. A complete commercial hood system, which is really the whole commercial kitchen ventilation setup, is made up of several engineered parts working together:
- The capture hood — the canopy over the appliances, sized to the equipment below it.
- Grease-rated ductwork — welded, liquid-tight steel duct that carries grease-laden air up and out.
- An exhaust fan — typically an upblast fan mounted on the roof that pulls air through the system.
- A make-up air unit — equipment that replaces the large volume of air the hood removes, so the building doesn't go into negative pressure.
- Fire suppression — for grease-producing cooking, a wet-chemical system plumbed into the hood.
Together, these form the commercial ventilation system that keeps a professional kitchen safe, breathable, and up to code. Commercial hoods themselves come in two code-defined types, and the difference between them drives nearly everything else about the installation:
| Hood type | What it's for |
|---|---|
| Type I (grease hood) | Required over appliances that produce grease and smoke — fryers, griddles, charbroilers, and ranges. Demands fire suppression and listed grease ducts. |
| Type II | Handles heat, steam, and odor only — dishwashers and many ovens. A commercial oven hood over a non-greasy oven is usually a Type II. |
These commercial canopies also come in familiar shapes — wall-mounted, island (double-canopy), back-shelf, and pass-over styles — chosen to match the kitchen layout. What truly sets all of them apart from a home appliance, though, is scale. Exhaust hoods for commercial kitchens are sized by code (IMC Section 507 and ASHRAE 154) according to hood length and cooking duty, and a single canopy can move well over 2,000 CFM. Add up every hood in a busy kitchen and the full exhaust hood system often totals several thousand CFM. That's the capacity a restaurant line genuinely needs — and far more air than any home kitchen should ever move.
Grease Hoods, Exhaust Fans, and Fire Safety
Because a Type I grease hood deals with flammable grease vapor, the entire commercial setup is built around safety and heavy-duty airflow rather than quiet convenience. Inside the canopy, stainless-steel baffle filters spin grease out of the airstream before it enters the duct. The commercial hood fan — usually an upblast exhaust fan bolted to the roof — then pulls that air up through welded, grease-rated ductwork. Large kitchens run multiple commercial kitchen hood exhaust fans across several hoods, and the commercial range hood fan is always sized to the system as a whole, never to one appliance. A commercial kitchen exhaust fan is paired with a dedicated make-up air unit so the building's air pressure stays balanced, and restaurant ventilation fans are built to run through long, uninterrupted service hours.
The part no operator can skip is fire protection. A Type I grease hood must have a wet-chemical fire-suppression system (per NFPA 17A) with interlocks that shut down the cooking appliances when the system discharges. Grease ducts have to be cleaned on a regular schedule, hoods are commonly UL 710 listed, and the whole assembly is subject to inspection. Heavier cooking — or industrial food processing — steps up again to an industrial exhaust hood engineered for even more extreme loads. None of these requirements apply to a home kitchen, and that gap is exactly why trying to graft a commercial system onto a house creates far more problems than it solves.
These obligations are ongoing, not one-time. Grease ducts and hoods in a working kitchen are cleaned on a recurring schedule — often quarterly for high-volume operations — and the suppression system is inspected regularly to stay compliant. Add the energy cost of moving thousands of CFM and conditioning the make-up air that replaces it, and it's clear why commercial ventilation is treated as building infrastructure rather than a kitchen appliance. A home simply never generates the grease load or the risk that justifies any of it.
How Commercial Hood Airflow (CFM) Is Calculated
Commercial airflow isn't a round number someone picks off a spec sheet — it's calculated. Codes base the required exhaust on the hood's style, the number of open sides, and the "duty" of the cooking equipment underneath. As a rule of thumb, a UL-listed commercial hood is often rated around 250 CFM per linear foot of hood, while an unlisted canopy is sized by formula — roughly 75 CFM for every square foot of hood face on a three-sided open canopy. A modest 3.5-by-10-foot canopy, for example, works out to about 2,625 CFM on paper. Cooking duty pushes the number further:
| Duty level | Typical equipment |
|---|---|
| Light duty | Ovens, steamers, and other low-grease appliances |
| Medium duty | Fryers, griddles, and open-burner ranges |
| Heavy duty | Charbroilers and high-grease cooking |
| Extra-heavy duty | Solid-fuel and wood-fired cooking |
On top of the exhaust itself, codes require that the air pulled out be replaced. Make-up air brings fresh outdoor air back into the kitchen, and in a compensating hood the internal make-up is capped (often at about 10% of the exhaust rate) so the hood still captures properly. Every one of these numbers is tuned for restaurant-scale cooking, which is why commercial figures land in the thousands of CFM — and why none of this math describes what a home kitchen actually requires.
Commercial, Restaurant, and Home Range Hoods: What's Actually Different
"Commercial range hood," "commercial kitchen range hood," "restaurant hood," "restaurant kitchen hood," "restaurant exhaust hood," and "restaurant vent hood" all point to the same thing: a code-regulated, grease-rated exhaust system serving a restaurant range. A residential range hood, by contrast, is a plug-in home appliance. The two look superficially similar but are built to completely different rulebooks. Here's how they compare side by side:
| Commercial / restaurant hood | Home (residential) range hood | |
|---|---|---|
| Typical airflow | ~1,000–6,000+ CFM (by code, hood length & duty) | 250–1,400 CFM (by cooktop width & BTU) |
| Construction | Welded stainless, listed grease ducts, roof exhaust | Stainless or glass, 4–10 in. duct (or ductless) |
| Fire suppression | Required for Type I (wet-chemical, NFPA 17A) | Not required |
| Power & air | 208–480V fans, 3-phase common, dedicated make-up air | 120V plug-in; make-up air only above ~400 CFM |
| Install & permits | Plan review, mechanical & fire permits, inspection | Standard install, no commercial permitting |
| Who it's for | Restaurants & foodservice kitchens | Home kitchens |
| Cost | Much higher — priced as an engineered system (hood, fans, suppression, ducting, permits) | Roughly $200–$3,000 for the hood |
The most important takeaway hides in that "who it's for" row. Code is triggered by commercial use, not simply by power: even a home-style range, if it's installed in a restaurant, must be fitted with a Type I or Type II commercial hood. That is the real line between a commercial vent hood and a home one — the setting and the rules that come with it, not just how many CFM the fan happens to move. A home cook who wants restaurant-level results is chasing the airflow, not the regulatory category.
Do You Need a Commercial Hood at Home? (Almost Never)
For a residential kitchen, a true commercial hood is the wrong tool for the job. It's engineered for restaurant duty you will never actually reach, it frequently needs 208–480V three-phase power and a dedicated make-up air unit, and dropping a grease-rated system into a house can pull you into commercial permitting, fire-suppression mandates, and rooftop fan work. You'd spend far more to solve a problem a home simply doesn't have — and you'd likely end up with a loud, oversized unit that's miserable to live with. Where a residential hood is measured in sones and tuned to stay livable at the dinner table, a commercial fan is built to move air, not to be quiet, so in a house it would dominate the room every time it ran.
There's one gray area worth naming. If you run a home-based food business — think cottage-food operations or a licensed home kitchen — your local health and fire codes may actually require commercial-grade ventilation, because the rules follow commercial use. That's a question for your local authority, not a hood you should guess at. For everyone else, including owners of pro-style 36- and 48-inch ranges, the answer is the same: you don't need a commercial system. You need a residential hood with enough airflow and good capture. The only thing genuinely worth borrowing from the commercial world is the CFM — and you can get that in a home appliance.
"Commercial-Style" vs. Actually Commercial: What Pro-Grade Means at Home
A lot of shoppers who type "commercial range hood" don't literally want a restaurant exhaust system — they want the look, the power, and the durability that the word "commercial" implies. That's a perfectly reasonable goal, and it's one a residential hood can deliver. "Pro-grade" at home really comes down to three things: airflow strong enough to clear a hot wok or a searing pan, construction that stands up to heat and grease (304 stainless steel, washable baffle filters), and a design that looks the part in a modern kitchen. You get the commercial-style aesthetic and the muscle without inheriting the fire-suppression plumbing, the three-phase wiring, or the permit paperwork. In other words, you can have a restaurant-grade home kitchen without a commercial kitchen.
How to Get Restaurant-Grade Power in a Home Kitchen
Getting "commercial-grade" performance at home comes down to CFM and capture, not a restaurant hood. For high-heat cooking — wok work, searing, heavy frying on a gas range — plan on 600 to 1,400 CFM, which is exactly where serious residential hoods now operate. Here's a rough guide to matching airflow to how you actually cook:
| Home cooking style | Suggested CFM |
|---|---|
| Light or occasional, electric/induction | 250–400 |
| Everyday cooking on a gas range | 400–650 |
| Frequent high-heat, searing, big-batch | 650–1,000 |
| Heavy wok cooking, restaurant-style at home | 1,000–1,400 |
CFM is only half the equation — capture matters just as much. A hood needs enough surface area and the right mounting height (24 to 36 inches above the cooktop for most models) to actually catch the plume before it escapes into the room. Pair strong airflow with washable 304 stainless baffle filters and a smart touch is even better: ROBAM's high-output models reach commercial-grade airflow in a home-friendly package. The R-Max 3 moves up to 1,400 CFM, the CleanAir Pro 86H1S hits 1,300 CFM, and models like the 52H1S (1,100 CFM), A672 (1,050 CFM), and U3 (1,000 CFM) give you serious power at different price points. Several add auto-adjusting suction that ramps up on its own when a burner roars or a pot reaches a rolling boil. For a full breakdown of how to match airflow to your burner output, see our guide to high-CFM range hoods for gas and high-heat cooking.
Unlike a commercial system, these run on a standard 120V outlet and install without commercial permits. A few practical rules make them perform their best: match the hood to your cooktop width (at least 30 inches for a 30-inch range), vent outside with the shortest, straightest duct you can and the right diameter (6 to 10 inches for higher CFM), and remember that above roughly 400 CFM your local code may ask for make-up air even at home. Browse ROBAM's 30-inch range hoods for the most common home size, or step up to the 36-inch range hoods for wider coverage over a larger range.
Commercial Recirculating Cooker Hoods and Ductless Options at Home
In the UK a range hood is called a "cooker hood," and a commercial recirculating cooker hood filters air and returns it to the room instead of venting outside — handy where running duct to the roof isn't feasible. The home version of that idea is a ductless (recirculating) range hood. It works by pulling air through a grease filter and then a carbon (charcoal) filter that absorbs odors before the air circulates back into the kitchen. It's a genuinely convenient option when outdoor venting is off the table, but it carries the same trade-off at any scale: filtering cannot remove heat, moisture, or combustion gases nearly as well as venting outdoors. For a gas range in particular, ducted is always the better choice when it's possible, because recirculation does nothing about the combustion byproducts gas cooking produces. When ducting truly isn't an option, a ductless (recirculating) range hood with a strong carbon filter — changed on schedule — is the practical fallback.
Common Mistakes When Shopping "Commercial" for a Home Kitchen
The biggest mistake is buying an actual commercial unit for a house: you inherit the noise, the oversized airflow, the heavy power requirements, and possibly the permitting, all to solve a problem you don't have. After that, the errors cluster around a few predictable points:
- Undersizing CFM for the way you cook. A 300-CFM hood looks fine on paper but can't keep up with gas or wok cooking.
- Bottlenecking the duct. A powerful hood choked by a 4-inch duct left over from a microwave vent will be loud and ineffective.
- Mounting too high. Install beyond the recommended range and you lose capture, forcing you to buy extra CFM to compensate.
- Ignoring make-up air. Above about 400 CFM, a home may need make-up air to avoid negative pressure — check local code.
- Choosing ductless for a gas range. Recirculating filters can't clear combustion gases; vent outside whenever you can.
FAQ: Commercial vs. Home Range Hoods
What's the difference between a commercial and a residential range hood?
A commercial hood is a code-regulated exhaust system for restaurants — grease-rated, roof-vented, with fire suppression and make-up air, moving thousands of CFM. A residential range hood is a 120V home appliance moving 250–1,400 CFM. The dividing line is commercial use and code, not just power.
Can I put a commercial range hood in my house?
You generally shouldn't. A true commercial hood often needs three-phase power, a make-up air unit, rooftop fans, and commercial permits, and it's overkill for home cooking. A high-CFM residential hood gives you the same capture performance without that burden.
Can I get a restaurant-style hood for my home?
Yes — just not an actual restaurant exhaust system. Plenty of residential hoods deliver the commercial-style look, 304 stainless construction, and 1,000-plus CFM power that "restaurant-style" implies, all on standard home power.
What is a grease hood (Type I) versus a Type II hood?
A Type I grease hood is required over appliances that produce grease and smoke, and it must have fire suppression. A Type II hood handles only heat, steam, and odor — for example, over a dishwasher or a non-greasy commercial oven.
How many CFM is a commercial kitchen hood?
It's sized by code to hood length and cooking duty, so a single canopy commonly exceeds 2,000 CFM and a full system runs several thousand. A home kitchen needs a fraction of that — 250–1,400 CFM depending on how you cook.
How much does a commercial hood cost compared to a home hood?
A commercial hood is priced as an engineered system — the hood plus fans, fire suppression, ducting, make-up air, and permits — so it runs far higher than a residential unit, which typically costs between about $200 and $3,000 for the hood itself.
Do home kitchens need a commercial hood for wok or high-heat cooking?
No. You need a residential hood with high airflow — 600 to 1,400 CFM — plus good capture area and correct ducting. That delivers restaurant-grade performance without a commercial system.
Do I need make-up air for a high-CFM hood at home?
Possibly. Many local codes require make-up air once a hood moves more than about 400 CFM, to replace the air it pulls out and keep your home from going into negative pressure. Check your local code before installing a high-output hood.
Is a commercial range hood louder than a residential one?
Usually, yes. Commercial fans are engineered to move huge volumes of air, not to stay quiet, so in a home they tend to overwhelm the room. Residential hoods are tuned for livable noise levels and often have several speeds, letting you run strong airflow without shouting over it.
Can I vent a range hood through a side wall instead of the roof?
Often, yes. Many residential hoods can vent horizontally through an exterior wall, which is common in homes without roof access. Keep the run short and straight, match the duct diameter to your CFM, and finish it with an exterior wall cap that has a backdraft damper. True commercial Type I systems, by contrast, are typically required to terminate above the roofline.
Does a home food business need a commercial hood?
It might. Because ventilation rules follow commercial use, a licensed home-based or cottage-food kitchen may be required to meet commercial standards. Confirm the requirement with your local health and fire authority.
