CaptiveAire Store Buying Guide for Commercial Kitchen Hoods

A CaptiveAire store is where many restaurant owners and facility buyers start when they need a complete commercial exhaust package, not just a canopy hanging over a range. CaptiveAire-style systems typically bundle the hood, grease filters, exhaust fan, make-up air, and related accessories so the kitchen can capture smoke, heat, and grease vapor while replacing the air you pull out. This guide is written for kitchen managers and buyers comparing ventilation packages: Type I grease hoods versus lighter-duty Type II hoods, wall canopy versus island canopy, and how sizing, overhang, and CFM interact with your cooking line. You will not find invented model numbers or prices here. Instead you will get practical questions to take to a dealer, mechanical contractor, or the CaptiveAire store counter so the package matches your menu, code path, and cleaning program. Treat the store as a specification conversation, not a catalog click. The right package depends on appliance type, fuel, duty, kitchen layout, and local fire and mechanical codes. Get those inputs right and the rest of the system (filters, fans, make-up air, and grease management) falls into place. For more background, see Learn more about captiveaire store.

What a CaptiveAire Store Actually Sells

Most commercial buyers are not shopping a single stainless box. A typical CaptiveAire-style package includes a canopy or proximity hood, baffle or other listed grease filters, an exhaust fan sized for the hood, a make-up air unit or damper strategy, and often listed accessories such as lights, fire-suppression interfaces, and grease cups or troughs. The store or dealer job is to match those pieces so capture, exhaust, and replacement air work as one system.

Type I hoods are listed for grease-laden cooking: fryers, griddles, charbroilers, woks, and similar appliances. Type II hoods handle heat and moisture from dishwashers, ovens, or some steam equipment where grease is not the primary hazard. Mixing those categories is a common specification error. If grease is present, you need a grease-rated hood, listed filters, and a fire-suppression plan that the authority having jurisdiction will accept.

Wall canopy hoods sit against a wall over a line of equipment. Island or double-island canopies hang over equipment that is accessible from more than one side and usually need more overhang and careful airflow so plumes do not escape the edges. Proximity or backshelf hoods sit closer to the cooking surface and can be efficient in tight spaces, but they are not a substitute for a full canopy when the menu is high-duty or the equipment is deep. Ask the CaptiveAire store which listed configuration matches your line, not which drawing looks most like a competitor kitchen.

Package pieces that must work together

Exhaust without make-up air creates negative pressure: doors slam, pilot lights flicker, and hood capture can actually get worse because the kitchen is starving for replacement air. Make-up air should be tempered as required by climate and code, introduced so it does not blow the plume out from under the canopy, and interlocked so it runs with the exhaust. Grease management, listed filters, drain paths, and accessible cups protect the duct and fan and are part of the fire-safety story, not an afterthought.

What to bring to the counter

Bring a scaled plan or at least accurate lengths of each cooking battery, appliance names and fuel types, ceiling height, roof or wall fan location constraints, and whether you already have a listed wet-chemical fire-suppression system. Note hours of operation and whether the dining room shares air with the kitchen. Those details change CFM, fan selection, and make-up air more than brand preference does.

Sizing, CFM, Overhang, and Capture That Actually Works

Hood length generally follows the cooking line, with listed overhang beyond the appliance footprint. Typical industry practice for wall canopies is extra coverage at the ends and front so the thermal plume stays under the filters; island canopies need overhang on all sides. Exact listed overhang is in the manufacturer installation instructions and listing. Do not guess from a photo. If equipment sits too far forward, no amount of fan speed will recover lost capture.

CFM is not a vanity number. It is driven by hood style, listed calculation method, appliance duty, and sometimes local amendments. High-duty charbroilers and woks throw more heat and grease than a bank of ovens. Undersizing CFM lets smoke roll into the kitchen. Oversizing without make-up air and proper velocity at the filters can create noise, energy waste, and still-poor capture if the canopy geometry is wrong. Ask the CaptiveAire store which calculation method they used (listed formula versus engineered design) and to show the duty assumptions.

Filter face velocity and slot or exhaust collar design matter as much as total CFM. Baffle filters need to be seated, oriented for grease drainage, and replaced or cleaned on a schedule so they do not clog and push effluent around the edges. Lights should be listed for the hood environment and positioned so staff can see the cooking surface without creating glare that hides smoke escape at the front lip.

Practical capture checks after install

After startup, watch the plume at the front lip during a full-fire cook, not at idle. Used safely and away from open flame, a smoke pencil at the edges helps spot spill. If capture fails only when the dining room HVAC is on, you likely have a pressure or make-up air placement problem, not a weak hood. Document fan RPM, belt condition, and damper positions so future cleaning contractors do not change a balanced system.

Codes, Fire Suppression, and Grease Duct Reality

Commercial kitchen exhaust is a code-driven system. In the United States, buyers typically encounter the International Mechanical Code, NFPA 96 for ventilation control and fire protection of commercial cooking operations, and local fire-marshal amendments. Hood listings, duct construction, clearances to combustibles, access panels, and termination of the exhaust fan all have to align. A CaptiveAire store can supply listed equipment; the installing contractor and AHJ still own the inspection path.

Fire suppression is usually a listed wet-chemical system covering the appliances, the hood plenum, and the duct as required. Nozzle placement follows the suppression manufacturer manual for each appliance type. Changing the menu by adding a charbroiler or wok can void coverage until the system is redesigned. Coordinate hood cutouts, pipe routing, and control interlocks (fan run, fuel or electric shutoff) early so the stainless work does not fight the suppression installer.

Grease ducts need proper slope, cleanouts, and listed wrapping or clearance methods where required. Fans on the roof should be listed for grease, with easy access for cleaning. Do not treat the duct as a dumpster for grease; that is how fires start between scheduled hood cleanings. Ask who owns the cleaning contract, what the interval is based on, and how access doors are labeled.

Inspection-ready documentation

Keep listing sheets, installation manuals, as-built drawings, suppression plans, and air-balance reports together. When a health or fire inspector asks how the CaptiveAire-style package was sized, you want a paper trail, not a verbal memory of what the store said last year.

Installation, Make-Up Air, and Day-to-Day Cleaning

Installation quality decides whether a well-specified hood performs. Hangers must carry the load; seams and hanging height must match the listing; and the canopy must be level so grease drains to the cups. Exhaust collars, duct transitions, and fan curbs need to be airtight on the exhaust side. Poor hanging height is a frequent field error: too high and capture collapses; too low and staff hit the lip and filters become a maintenance headache.

Make-up air should be introduced at a location and velocity that does not short-circuit the hood. Dumping cold air at the front lip is a classic way to ruin capture. In cold climates, untempered make-up air also creates staff complaints and frozen product issues. Interlocks should start exhaust and make-up together. Demand-control or variable-speed systems, where used, need sensors and commissioning so they do not drop below capture during a rush.

Cleaning is operations, not a brochure feature. Baffle filters come out, are soaked or run through a listed process, and go back in the correct orientation. Grease cups are emptied before they overflow into the plenum. Interior hood surfaces need scheduled degreasing. The exhaust fan and duct need professional cleaning at intervals driven by grease production, not a generic calendar copied from another concept. Train closing staff to look for missing filters; a hood with gaps is not a listed assembly.

Energy, noise, and neighbor issues

Oversized fans waste energy and can violate noise limits at property lines. Undersized fans get cranked up until belts scream. A CaptiveAire store conversation should include fan location, curb, weather, and whether a pollution-control unit is required by the landlord or AHJ. Those choices affect roof structure, electrical service, and ongoing filter or electrostatic precipitator maintenance if you add downstream treatment.

How to Compare Options at a CaptiveAire Store

Compare apples to apples: same hood type, same listed overhang, same duty assumptions, same make-up air strategy, and the same fire-suppression interface. A cheaper canopy that is shorter than the line, missing end overhang, or sold without a grease-rated fan is not a bargain. Ask for the submittal package: drawings, listings, filter type, fan curve, and make-up air data.

Serviceability matters after opening. Can your cleaning company remove filters without special tools? Are grease cups accessible during service? Is the fan a common listed model your local tech can belt and balance? Warranty language should be read against who installs the system; factory equipment warranties often assume listed installation and start-up.

If you are replacing an existing hood, measure the old canopy, note problems (smoke at the pass, grease on the ceiling, door slam), and decide whether the cooking line itself changed. Reusing a duct that is undersized, unlisted, or impossible to clean can sabotage a new CaptiveAire-style hood. Budget for duct and roof work, not only stainless.

A simple buyer checklist

Confirm Type I versus Type II, wall versus island, overhang all around the equipment, CFM method and make-up air CFM, listed filters and cleaning access, fire-suppression coverage for today menu, grease duct and fan listing, start-up balance report, and a written cleaning interval tied to your actual grease load. Take that list to the CaptiveAire store and to your mechanical contractor so both parties own the same scope.

Frequently Asked Questions

Is a CaptiveAire store only for CaptiveAire-branded kitchens?

Dealers and storefronts that sell CaptiveAire-style packages typically focus on that manufacturer listed hoods, fans, and make-up air, but your project still needs a licensed installer and AHJ approval. You are buying a listed system and a specification conversation, not a one-click appliance. Ask what is included in the package versus what the mechanical contractor must furnish, such as duct, curbs, gas valves, and suppression.

How do I estimate CFM before I visit a CaptiveAire store?

You can sketch the cooking line length, appliance types, and whether the hood is wall or island, then ask the dealer to run the listed calculation. Do not pick a round number from a forum. Duty (light, medium, heavy, extra-heavy) and local code method change the result. Bring photos and model names of fryers, broilers, and woks so the duty assumption is honest.

Do I always need make-up air with a commercial exhaust hood?

If you exhaust a significant volume of air, you need a planned replacement-air path. Code and good practice generally require mechanically introduced make-up air for commercial kitchen exhaust, especially at restaurant-scale CFM. Skipping it causes negative pressure, poor capture, and comfort problems. The CaptiveAire store should size make-up air with the exhaust, not as an optional add-on.

How often should hood filters and ducts be cleaned?

Filter cleaning is frequent, often daily to weekly depending on fryers and charbroilers, because clogged baffles destroy capture and increase fire risk. Duct and fan cleaning follows grease production and NFPA 96-oriented schedules used by your AHJ and cleaning contractor. High-volume solid-fuel or heavy charbroiling needs more frequent professional cleaning than a light saute line. Never operate with missing filters.

Can I reuse my old fire-suppression system with a new hood?

Sometimes, if coverage, nozzle listing, pipe routing, and appliance layout still match the suppression manufacturer design. New hood geometry, added appliances, or relocated batteries usually require a redesign and inspection. Coordinate the CaptiveAire-style hood drawing with the suppression contractor before fabrication so cutouts and mounting points are correct.

Conclusion

A CaptiveAire store is most useful when you arrive with a real cooking line, a code path, and a plan for make-up air, grease cleaning, and fire suppression. Specify capture first (hood type, overhang, listed CFM) then match fans and replacement air so the kitchen stays balanced during the rush. Next step: gather appliance lists and a simple floor plan, then ask the dealer and your mechanical contractor for a complete submittal, not a canopy-only quote. Commercial Kitchen Hood Guides recommends you verify listings, start-up balance, and a written cleaning program before you sign, so the package you buy is the package inspectors and cooks can live with.
