Kitchen Ventilation Hood Suppliers: Selecting the Right System for Your Restaurant

Exhaust hood selection is one of the most consequential infrastructure decisions in restaurant design, and it is one of the most frequently under-engineered. Operators focus on cooking equipment, POS systems, and interior design — the hood gets treated as a code compliance checkbox. Then they spend years dealing with a hot, smoky kitchen, health inspection issues, and energy costs that should not exist.

The right exhaust hood system removes grease-laden vapors, controls heat, maintains comfortable working conditions for kitchen staff, and manages fire risk. The wrong one creates all of the above problems and more. Here is what you need to know before selecting a vendor.

Type 1 vs. Type 2: Start Here

The most fundamental decision in hood selection is hood type, and it is determined by what you are cooking, not what you prefer.

Type 1 hoods are required over any equipment that produces grease-laden vapors — fryers, grills, broilers, woks, charbroilers, ranges, and most standard cooking equipment. They include grease filtration (baffle or mesh filters), grease collection troughs, and must connect to grease-rated exhaust fans capable of handling grease-laden air. Type 1 hoods are also where fire suppression systems are installed. If you are cooking anything that produces visible smoke or steam with grease content, you need a Type 1 hood.

Type 2 hoods handle heat and steam without grease, making them appropriate for dishwashers, steam tables, ovens producing only heat vapors, and similar equipment. They require significantly less infrastructure than Type 1 and cost less to purchase and install. A common and expensive mistake is installing only a Type 2 hood over equipment that actually requires Type 1 coverage — this creates a code violation that requires costly retrofit.

When in doubt about which type you need, err toward Type 1. Your local fire marshal or mechanical engineer can confirm requirements for specific equipment.

The Major Manufacturers

CaptiveAire is the dominant US manufacturer of commercial kitchen ventilation systems and the most widely specified brand among food service consultants and architects. Their systems appear in thousands of commercial kitchens across every segment from fast casual to fine dining. CaptiveAire manufactures the full system — hood, fan, makeup air unit — which simplifies the coordination of system components.

Greenheck is another major player, known for quality exhaust fans and makeup air units. They offer complete ventilation system packages and have a strong reputation in commercial construction generally, with restaurant applications representing a significant portion of their business.

Halton differentiates through advanced technology. Their Capture Jet technology improves containment efficiency — capturing cooking vapors within a smaller hood footprint or capturing more effectively from the same footprint. More significantly, Halton offers demand-controlled kitchen ventilation (DCKV) that adjusts fan speed based on real-time cooking activity using sensors that detect heat and vapor levels. A kitchen running at 20% capacity does not need the same exhaust volume as one running at full production. DCKV systems typically reduce ventilation energy costs by 40-60% compared to constant-speed systems, which translates to several thousand dollars annually in large operations.

For direct purchasing, HoodMart offers factory-direct commercial exhaust hoods with NSF, UL, NFPA, and ETL approvals. Their pricing model bypasses distributor markups. Hood Depot has manufactured custom ventilation systems since 1971 and is trusted by food service consultants for complex custom applications.

Sizing: Where Most Errors Occur

Undersized hoods are the primary failure mode. A hood that cannot capture all the cooking vapors produced by the equipment beneath it fails at its core function, creating grease buildup in the kitchen, indoor air quality problems, and fire risk. The hood must extend beyond the cooking equipment on all sides — typically 6 inches on the sides and back, and 12 inches in front of the equipment (or sufficient overhang to capture all vapors).

Exhaust volume (measured in CFM — cubic feet per minute) must match the cooking equipment’s heat output and vapor production. Equipment with higher BTU output, or equipment that produces more smoke and vapor (charbroilers, woks, fryers), requires higher exhaust volumes. Your hood manufacturer or a qualified mechanical engineer should size the system based on your specific equipment list — not on the square footage of the kitchen.

Makeup air is the other side of the exhaust equation that is frequently neglected. For every cubic foot of air exhausted, an equal volume must be supplied as makeup air. Without adequate makeup air, the kitchen goes into negative pressure, causing back-drafting of combustion gases from cooking equipment, difficulty opening doors, and uncomfortable working conditions. Makeup air systems must be designed in coordination with the exhaust system — this is why working with a manufacturer like CaptiveAire that produces both components simplifies the engineering.

Demand-Controlled Ventilation: The ROI Case

For any restaurant with projected annual energy costs above $30,000, demand-controlled ventilation (DCKV) is worth serious evaluation. The economics are straightforward: a conventional exhaust system runs at full speed regardless of actual cooking activity. A kitchen that uses full exhaust capacity for three hours during peak service and idles at low production for eight hours is paying for full-speed ventilation during those idle hours.

DCKV systems use sensors (typically infrared, ultraviolet, or temperature-based) to detect actual cooking activity and adjust fan speed accordingly. Speed reductions translate directly to energy savings — fan energy consumption follows the cube law, meaning a 50% speed reduction reduces power consumption by approximately 87%.

Halton’s DCKV technology is the most established in the market, but CaptiveAire and Greenheck also offer demand-controlled options. Payback periods vary by operation, but 18-36 months is common for high-volume kitchens. LEED certification projects almost always include DCKV.

Filter Selection and Maintenance

Hood filters require regular cleaning on schedules tied to cooking volume. Baffle filters are the standard in commercial kitchens — they work by changing airflow direction, causing grease droplets to separate and collect in troughs. Mesh filters are less common in modern installations because they clog faster and are harder to clean, though they appear in older kitchens.

NFPA 96 specifies cleaning frequency based on cooking volume. High-volume fryer-heavy operations may need filter cleaning weekly. Lower-volume operations may qualify for monthly schedules. Neglected filters create two problems: reduced airflow effectiveness and fire risk as accumulated grease becomes a fuel source.

Most commercial kitchens clean baffle filters in their commercial dishwasher, which works effectively if the machine runs hot enough and uses appropriate detergent. Some operators send filters through dedicated hood cleaning services that include the duct work and interior hood surfaces — required by NFPA 96 on a schedule tied to volume.

Getting Competitive Bids

Ventilation system pricing varies significantly by manufacturer, configuration, and local installation costs. For a straightforward single-zone restaurant installation, system and installation costs together typically range from $8,000 to $25,000 depending on hood length, fan capacity, and whether makeup air is included.

Get bids from at least two manufacturers and ensure you are comparing equivalent specifications — same CFM, same hood length, equivalent filter systems. Lower bids that achieve the specification by undersizing the fan are a false economy.

For new construction, involve your ventilation contractor during the design phase, before equipment placement is finalized. A hood system designed around finalized equipment placement integrates more effectively and avoids the compromises that come with fitting a standard product around pre-placed equipment.

Integration Requirements

Ventilation systems integrate with three other systems that must be coordinated during design and installation.

Fire suppression integration is mandatory. Type 1 hoods require UL300-listed wet chemical suppression systems installed within the hood plenum. The suppression system vendor and the hood vendor must coordinate nozzle placement, chemical quantity, and the activation mechanism. Some manufacturers like CaptiveAire supply integrated systems; others require separate coordination.

HVAC coordination determines whether the building’s heating and cooling system needs to compensate for the ventilation system’s effect on building pressure and temperature. In some climates, makeup air must be conditioned (heated in winter, cooled in summer) to avoid extreme temperature changes in the kitchen. This adds to system cost but is necessary for staff comfort and energy management.

Grease duct routing must be planned from the start. The duct connecting the hood to the exhaust fan and ultimately the exterior must meet NFPA 96 requirements for clearances from combustible materials and must be accessible for inspection and cleaning. Grease duct routing is often a major structural planning consideration in multi-story buildings.

Red Flags in Vendor Evaluation

Three warning signs in vendor proposals warrant immediate scrutiny.

The first is undersizing for cost. A bid that is 30-40% lower than competitors often means lower CFM specifications. Ask for the CFM calculations justifying the proposed system for your equipment list. A lower-priced system that does not adequately capture cooking vapors is worthless.

The second is failing to account for makeup air. Proposals that specify the exhaust system without addressing makeup air are incomplete. Makeup air is half the system. A vendor who ignores it either lacks experience or is omitting it from scope to win on price.

The third is proprietary restrictions on service. Some manufacturers use proprietary components that can only be serviced by their own technicians, creating long-term service cost monopolies. Ask about parts availability and whether third-party qualified technicians can service the system.
