Kitchen Aire Range Hood Guide for Commercial Kitchens

A kitchen aire range hood is the center of a commercial exhaust package: the canopy over the line, plus filters, ductwork, an exhaust fan, and usually makeup air. Restaurant owners and facility buyers often use the phrase when they mean CaptiveAire-style Type I systems built for grease-laden cooking, not a residential wall hood. For more background, see Learn more about kitchen aire range hood.

Choosing well is about capture, not chrome. Hood length, overhang, mounting height, and exhaust airflow (CFM) must match the appliances and the way cooks work the line. Undersize the hood and smoke rolls into the dining room. Oversize the fan without makeup air and you fight doors that slam, pilot lights that snuff, and uncomfortable kitchens.

This guide walks through canopy styles, practical sizing, codes and fire suppression, grease management, installation coordination, and cleaning. It does not invent model numbers or prices. Use it to brief a licensed hood contractor and your local AHJ before you order steel.

What a Kitchen Aire Range Hood System Includes

In commercial work, a kitchen aire range hood is rarely a single box. A typical CaptiveAire-style package includes a stainless canopy (wall or island), listed grease filters, a listed exhaust fan (often a roof upblast or utility set), grease duct, and a makeup-air unit that replaces exhausted air. Many bids also include a listed fire-suppression system, control interlocks, and sometimes a demand-control kitchen ventilation (DCKV) package that modulates fans with cooking load.

Type I hoods are for grease-producing equipment: ranges, fryers, griddles, broilers, and woks. Type II hoods handle heat and steam from dishwashers, ovens, and some steamers where grease is not the issue. Mixing those up is a common bid error. If the line produces grease-laden vapor, you need a Type I canopy, listed filters, and grease-rated duct-not a condensate hood with a light-duty fan.

Think in systems. Capture happens at the canopy lip. Transport happens in smooth, correctly pitched grease duct. Exhaust happens at a listed fan that can handle grease and weather. Replacement air happens at makeup-air registers that do not blow the plume off the filters. If any one of those is wrong, the hood looks fine on paper and fails on a Saturday night.

Wall, island, and proximity canopies

Wall-mounted canopies are the workhorse for a cookline against a wall. Island (or double-island) canopies serve island suites and need capture on more sides, so they often need more overhang and more airflow for the same equipment. Proximity or backshelf hoods sit closer to the equipment; they can work for some lines but leave less room for tall stockpots and may need tighter appliance placement.

Ask the manufacturer and your engineer which canopy style is listed for your appliance mix. A broiler or wok battery is not the same capture problem as a row of convection ovens. Do not assume a shorter proximity hood will save money if it cannot contain the plume.

Filters, fans, and makeup air

Listed baffle filters are standard on grease hoods; they must be removable, cleanable, and installed in the correct orientation. Exhaust fans for Type I systems are typically listed for grease and installed so they discharge up and away from intakes. Makeup air should be tempered when climate requires it, and it should be interlocked so the exhaust cannot run without replacement air where the code and listing require that.

DCKV can cut energy use on lines that idle between rushes, but it is not a substitute for correct design CFM. Sensors and VFDs still need a hood that captures at full fire. Treat energy controls as an add-on after the capture math is honest.

Sizing, CFM, Overhang, and Capture That Actually Works

Sizing starts with the cooking equipment, not a round number from a catalog. Engineers and manufacturers use listed calculation methods (often based on hood style, duty of the appliances, and length of the cooking surface). High-duty equipment-charbroilers, woks, upright broilers-needs more exhaust per foot than a bank of steamers. Your kitchen aire range hood should be long enough to cover the entire battery, including the space between appliances where plumes merge.

Overhang is the extra canopy beyond the cooking surface. Typical commercial practice is several inches on the ends and a meaningful front overhang so the plume is not sheared by walk-by traffic. Exact inches belong in the manufacturer's listing and the engineered drawings-not in a blog as fake specs. If cooks work the front of a range with tall pots, you need enough front overhang and a mounting height that still keeps the filters in the listed range.

Mounting height matters. Too high and the plume spreads before it hits the filters. Too low and you violate listings, hit heads, or block fire-suppression nozzles. Follow the hood listing, the fire-suppression listing, and the appliance clearances together. CFM on the drawing must be available at the canopy after duct losses, not only at the fan nameplate. A fan that is "big enough" on a spreadsheet can still be starved by long grease duct, elbows, or a dirty filter bank.

Makeup air and kitchen pressure

Commercial kitchens should not run as uncontrolled negative boxes. Excessive negative pressure pulls dining-room air through the pass, slams doors, and can affect gas appliances. Makeup air is typically a large fraction of exhaust; the exact ratio is a design and code issue. Supply registers should be placed so they do not create a draft across the hood lip.

If your existing kitchen "never had makeup air" and "worked anyway," that often means the building leaked. A tighter remodel or a new rooftop package will expose the missing air. Plan makeup air in the same bid as the kitchen aire range hood, including structural curb space and electrical.

Codes, Listings, and Fire Suppression You Cannot Skip

Commercial exhaust is a listed, inspected system. In the United States, buyers typically run into the International Mechanical Code (IMC), NFPA 96 for ventilation control and fire protection of commercial cooking operations, and local amendments. The hood, filters, fan, duct, and fire-suppression system each need the right listings. Your authority having jurisdiction (AHJ)-building, fire, and sometimes health-signs off. A kitchen aire range hood that is not installed to its listing is a failed inspection waiting to happen.

Grease duct has rules for materials, clearance to combustibles, access for cleaning, and slope toward a collection point. Welded liquid-tight duct is common for grease. Access panels must be where cleaners can actually reach them. Fire-rated enclosures or listed wrap may be required depending on routing. Do not hide grease duct in a chase with no cleanouts.

Fire suppression (often a listed wet-chemical system) protects the appliances, the plenum, and the duct, with nozzles aimed per the manufacturer's design. Fuel shutoff, electrical interlocks, and manual pulls are part of the system. Hood lights, fan switches, and DCKV must not defeat the suppression or the required fan operation during a fire sequence. Coordinate the hood vendor, the suppression contractor, and the electrician early.

What inspectors commonly flag

Typical punch-list items include missing overhang relative to the drawing, filters left out or installed backward, makeup air not interlocked, grease duct without enough access, suppression nozzles blocked by shelves, and exhaust discharging too close to fresh-air intakes. Another frequent issue is adding a charbroiler later without revisiting hood length and CFM.

Keep a packet: listings, as-builts, air-balance report, suppression drawings, and cleaning logs. That packet speeds inspections and insurance questions after a remodel.

Grease Management, Cleaning, and Day-to-Day Operation

Grease that is not captured becomes a film on walls, a slip hazard, and a fire load in the duct. Filters should be scheduled for cleaning based on cooking volume, not a guess. High-volume fryer and broiler lines may need filters washed far more often than a light sauté station. Never run a Type I hood with missing filters; that sends grease into the duct and fan.

Hood interiors, grease gutters, and drain paths need regular wiping. Duct cleaning frequency should follow NFPA 96 inspection intervals and your actual grease accumulation-solid-fuel or heavy charbroil lines need more aggressive schedules. Use qualified duct cleaners who open the listed access points rather than "flushing from the fan" and calling it done.

Train the crew: who pulls filters, who logs the wash, who calls the suppression company after any discharge, and who does not hang ladles from the canopy lip. A kitchen aire range hood only captures if the plume can enter. Storage on the front edge, missing end panels, or a blast chiller vent blowing across the line will defeat an expensive canopy.

Installation and commissioning checklist

Confirm roof structure and curb locations before the hood ships. Coordinate gas, electric, fire alarm, and suppression. After install, commission with an air-balance: measure exhaust and makeup air, check capture with a smoke test or equivalent at typical cooking, and verify interlocks. Photograph filter orientation and nozzle aiming for your records.

If capture fails, the fix is rarely "turn the fan up" forever. Look at overhang, height, cross-drafts, missing end panels, clogged filters, and duct restrictions first. Then revisit design CFM with the engineer.

How Buyers Should Compare CaptiveAire-Style Packages

Compare complete packages, not canopy price alone. Ask what is included: hood, filters, lights, fan, makeup-air unit, curbs, controls, suppression (if by the same vendor), startup, and warranty handling. Ask who engineers the CFM and who stamps drawings for permit. A low steel price with no makeup air and no duct design is not a bargain.

Match the hood to the menu. A ghost kitchen adding a second broiler next year needs extra canopy length or a documented path to extend. Island suites need different capture than a wall line. If you are replacing only the canopy on old duct, verify the duct and fan still meet current grease and listing requirements.

Get three comparable bids with the same appliance list, the same canopy style, and the same assumption about makeup air. Require listed equipment, an air-balance, and cleaning access on the drawings. Use this article as a briefing document so vendors cannot skip Type I vs Type II, overhang, or fire suppression in the fine print.

Questions to put in the RFP

What listing covers this canopy for our appliance duty? What exhaust CFM is designed at the hood, and what static pressure is assumed? How is makeup air volume, temperature, and register location determined? Who provides NFPA 96-aligned duct access? Who designs and installs suppression? What is the filter type and cleaning recommendation for our menu? How are fans interlocked with makeup air and fire alarm?

Frequently Asked Questions

What is a kitchen aire range hood in a restaurant context?

Buyers usually mean a commercial Type I exhaust canopy and the related CaptiveAire-style package: filters, grease duct, exhaust fan, and makeup air. It is not a residential range hood. Specify the cooking equipment and whether you need a wall, island, or proximity canopy so vendors quote the right listing.

How much CFM does a commercial kitchen aire range hood need?

There is no single CFM that fits every line. Exhaust airflow is calculated from hood style, appliance duty, and canopy length, then checked against duct losses so the fan delivers that air at the filters. High-duty broilers and woks need more exhaust per foot than light ovens. Ask for engineered CFM at the hood, not only a fan catalog number.

Do I need makeup air with a kitchen aire range hood?

Most commercial Type I systems need planned makeup air so the kitchen does not go excessively negative. Volume, tempering, and register placement are design issues. Makeup air should be coordinated with the exhaust fan and, where required, interlocked. Skipping it often shows up as slamming doors, poor capture, and unhappy cooks.

What codes apply to commercial exhaust hoods?

Projects commonly follow the IMC, NFPA 96, manufacturer listings, and local fire and health amendments. The AHJ inspects the installed system. Hood, duct, fan, filters, and fire suppression must be listed and installed per those documents. Your contractor should submit drawings and listings with the permit.

How often should grease filters and ducts be cleaned?

Filter washing follows cooking volume; heavy fryer and broiler lines need frequent cleaning. Duct inspection and cleaning intervals should follow NFPA 96 guidance and actual grease buildup. Never operate a Type I hood without the listed filters in place. Keep logs for inspectors and insurers.

Can I add a charbroiler under an existing hood later?

Only if the canopy length, overhang, listing, CFM, duct, and suppression coverage still match the new duty. Adding high-duty equipment under a hood designed for lighter cooking is a common reason capture and inspections fail. Have an engineer and the suppression contractor review before the appliance is ordered.

Conclusion

A kitchen aire range hood succeeds when capture, exhaust, makeup air, grease duct, and fire suppression are designed as one listed system. Size from the appliances, protect overhang and mounting height, and budget cleaning access from day one.

Next, list every piece of cooking equipment, decide wall versus island, and send that package to licensed hood, mechanical, and suppression contractors plus your AHJ. Compare complete CaptiveAire-style bids-not canopy steel alone-and require an air-balance before you sign off.
