Commercial Kitchen Exhaust System Cost in India: Complete 2026 Buying Guide
Restaurant owners usually budget carefully for burners, refrigeration, preparation tables and cooking equipment.
The exhaust system is often considered later.
By that stage, the cooking line may already be installed, the ceiling may be finished and the available duct route may be restricted. This can increase fabrication difficulty, installation cost and the risk of poor performance.
A commercial kitchen ventilation system is not only a stainless-steel hood mounted above a cooking range.
It may include:
- Exhaust hood or canopy
- Grease filters
- Exhaust ducting
- Centrifugal blower or exhaust fan
- Fresh-air or replacement-air arrangement
- Electrical controls
- Supports and installation
- Cleaning-access panels
- Fire-safety provisions where applicable
Commercial kitchen ventilation must be planned as one connected system. ASHRAE describes it as an interaction between exhaust, replacement air, cooling, building pressure, fire safety and cooking equipment.
This guide explains indicative commercial kitchen exhaust costs in India, the factors that affect pricing, material choices, blower selection, duct planning and the mistakes buyers should avoid.
Quick Answer: How Much Does a Commercial Kitchen Exhaust System Cost in India?
A basic commercial kitchen exhaust arrangement may begin around ₹30,000–₹60,000, while a larger restaurant, hotel or banquet-kitchen system can cost ₹1.5 lakh–₹3 lakh or more.
The final quotation depends on:
- Hood length and depth
- Stainless-steel grade and thickness
- Type of cooking equipment
- Heat, smoke and grease load
- Duct length
- Number of bends
- Blower capacity and static-pressure requirement
- Exhaust outlet location
- Fresh-air requirement
- Floor level and installation access
- Fire-safety scope
- City, freight and site conditions
The hood is only one part of the cost. Duct routing, blower selection and site installation can significantly change the final amount.
All prices in this article are indicative planning ranges. Request a current written quotation for the specified material, fabrication and site scope.
Commercial Kitchen Exhaust System Cost Breakdown
1. Stainless-Steel Exhaust Hood
The hood captures heat, smoke, vapour and grease-laden air rising from the cooking equipment.
Indicative Indian supplier listings show large variation in hood pricing because products differ in dimensions, steel grade, thickness, construction, filter arrangement and whether the quoted amount includes installation. Recent supplier listings include stainless-steel hood rates around ₹2,300–₹3,300 per running foot for certain configurations, while customised or larger systems can cost considerably more.
Factors affecting hood price
- Length and depth
- Wall-mounted or island design
- SS304, SS202 or another specification
- Sheet thickness
- Baffle-filter quantity
- Lighting provision
- Fresh-air integration
- Welding and finish quality
- Hanging supports
- Site installation
Practical planning range
| Hood requirement | Indicative planning range |
|---|---|
| Small 5–6 ft wall hood | ₹15,000–₹35,000 |
| Medium 8–12 ft hood | ₹30,000–₹70,000 |
| Large customised hood line | ₹70,000–₹1,50,000+ |
These are not fixed quotation prices.
2. Grease Filters
Restaurants using fryers, tandoors, griddles, kadai cooking or wok ranges produce grease-laden vapour.
The hood should include a suitable grease-removal arrangement.
Commercial systems commonly use removable baffle-type grease filters because they can be cleaned and reused. NFPA 96 separately addresses hoods, grease-removal devices, exhaust ducts, air movement, fire-extinguishing equipment and ongoing maintenance as connected parts of commercial cooking ventilation.
Confirm before ordering
- Filter material
- Filter dimensions
- Number of filters
- Removal method
- Cleaning access
- Replacement availability
- Drain channel or grease cup provision
Do not judge the entire hood only by its external stainless-steel appearance.
3. Exhaust Blower
The blower moves extracted air through the duct and discharges it outside the building.
A blower cannot be selected correctly using only the hood length.
The designer must also consider:
- Required airflow
- Duct length
- Duct diameter or cross-section
- Number of bends
- Vertical rise
- Filters
- Static-pressure losses
- Discharge arrangement
- Noise
- Motor power
- Available electrical supply
Common options
Axial-flow fan:
May be considered for selected low-resistance and shorter exhaust arrangements.
Centrifugal blower:
Commonly considered where the duct run, bends, filters or resistance require greater pressure capability.
Indicative planning range
| Blower type | Indicative range |
|---|---|
| Basic exhaust fan or axial arrangement | ₹15,000–₹30,000 |
| Commercial centrifugal blower | ₹30,000–₹60,000+ |
| Larger high-pressure system | Project-specific |
Do not buy the blower before the duct route and hood requirement are understood.
4. Ducting
Ducting carries extracted air from the hood to the outdoor discharge point.
This is often the most underestimated part of the project.
The cost depends on:
- Duct material
- Thickness
- Total length
- Shape and cross-section
- Number of bends
- Vertical shaft
- Roof or wall discharge
- Access panels
- Supports
- Insulation where required
- Installation height
- Scaffolding
- Fire-separation requirements
A kitchen with the same hood size may cost much more when the duct must:
- Travel through several floors
- Pass around structural beams
- Use multiple bends
- Reach the terrace
- Cross occupied areas
- Require weatherproof outdoor work
Always inspect the proposed duct route before approving the final exhaust quotation.
5. Fresh Air or Replacement Air
When a kitchen exhausts a large amount of air, replacement air must enter the space.
Without proper replacement air, the kitchen may experience:
- Negative pressure
- Difficult-to-open doors
- Air entering through unwanted gaps
- Reduced hood capture
- Excessive heat
- Dining-room air being pulled toward the kitchen
- Pressure interaction with air conditioning
ASHRAE states that commercial kitchen ventilation includes exhaust, replacement air and cooling, and these systems must be integrated and balanced rather than designed separately.
There is no universal percentage suitable for every kitchen.
The replacement-air requirement depends on:
- Exhaust volume
- Building pressure
- Hood design
- Air-conditioning arrangement
- Local climate
- Kitchen layout
- Outdoor-air conditions
- Applicable building and fire requirements
Fresh-air cost may range from a relatively simple fan-and-duct arrangement to a more advanced conditioned-air system.
6. Fire-Safety Provisions
Commercial kitchens using grease-producing cooking equipment may require specific fire-safety provisions depending on:
- Building type
- Local fire requirements
- Mall or hotel rules
- Insurance conditions
- Cooking equipment
- Fuel type
- Exhaust configuration
- Applicable authority approval
Possible provisions may include:
- Suitable grease filters
- Fire-rated duct requirements
- Accessible cleaning panels
- Fire-extinguishing system
- Gas shut-off integration
- Electrical interlocks
- Safe discharge location
NFPA 96 covers commercial cooking hoods, grease-removal devices, exhaust ducts, air movement, fire-extinguishing systems, inspection and maintenance. Indian projects must still follow the requirements of the local authority having jurisdiction.
Do not assume that a standard hood quotation includes the fire-suppression system.
Ask for inclusions and exclusions in writing.

The project should be measured and quoted after confirming the cooking line and site conditions.
How Is Exhaust Airflow Calculated?
Airflow is commonly expressed as CFM—cubic feet per minute.
A simplified area-based calculation may be useful during an early discussion, but it should not be treated as the final engineering selection.
Final airflow depends on:
- Hood type
- Hood dimensions
- Cooking-equipment duty
- Heat output
- Smoke and grease generation
- Appliance arrangement
- Hood mounting height
- Hood overhang
- Cross-drafts
- Duct resistance
- Filters
- Replacement air
- Local requirements
A kitchen with boiling and light cooking does not have the same ventilation load as:
- Heavy frying
- Charcoal cooking
- Tandoor
- High-flame wok cooking
- Multiple kadai stations
ASHRAE guidance treats hood selection and exhaust-air rate as critical design decisions because they affect replacement air, energy use, comfort and overall system performance.
Do not purchase a blower solely from a general online CFM formula. Ask the supplier or ventilation designer to calculate the complete hood, duct and pressure requirement.
SS304 vs SS202 vs GI: Which Material Should You Choose?
SS304
SS304 may be preferred for:
- Visible hood sections
- Wet or steam-heavy kitchens
- Corrosion-sensitive applications
- High-cleaning-frequency areas
- Premium commercial installations
It generally offers stronger corrosion resistance than lower-nickel stainless-steel grades.
SS202
SS202 may be considered for selected budget-sensitive applications depending on:
- Moisture exposure
- Cooking load
- Cleaning chemicals
- Maintenance
- Project lifespan
- Location
The grade should be stated clearly in the quotation.
GI Ducting
Galvanised iron is commonly considered for concealed commercial ducting where permitted and appropriately specified.
It may offer a cost-effective solution for longer duct runs.
Practical buying approach
- Select the hood material according to visibility, moisture, cooking load and budget.
- Select the duct material according to design, fire requirements and site conditions.
- Confirm material grade and thickness in writing.
- Do not accept only the description “stainless-steel exhaust system.”
FSSAI’s food-service hygiene framework expects equipment and containers to be non-toxic, non-corrosive, impervious and easy to clean and disinfect, while also requiring adequate ventilation within the premises.
Seven Costly Exhaust-System Mistakes
1. Finalising the Kitchen Before Planning the Duct Route
The cooking line, ceiling and exhaust route should be planned together.
A late duct decision can increase bends, distance and installation cost.
2. Buying the Blower Before Calculating System Resistance
A blower must overcome the resistance created by filters, duct length, bends and discharge conditions.
Buying only by motor horsepower or advertised CFM can lead to poor performance.
3. Installing a Hood That Does Not Capture the Full Cooking Plume
The hood must be selected according to the equipment placed below it.
Its size, position, mounting height and capture area should follow the equipment duty, hood design, manufacturer guidance and applicable requirements.
4. Ignoring Replacement Air
Exhausting air without planning how it returns can disturb kitchen pressure and hood performance.
Replacement air and exhaust should be designed together.
5. No Cleaning Access
Grease may collect inside filters, hood surfaces and ducts.
Access panels should be planned where inspection and cleaning will be required.
Retrofitting cleaning access later can be difficult and expensive.
6. Choosing the Cheapest Duct Route Instead of the Safest Practical Route
A short route may appear economical but still be unsuitable if it:
- Discharges near windows
- Creates odour complaints
- Is difficult to clean
- Passes through restricted areas
- Conflicts with fire requirements
7. Ignoring Noise
A high-speed or poorly isolated blower may create uncomfortable noise or vibration.
For an open kitchen, café or guest-facing area, ask about:
- Blower location
- Motor speed
- Vibration isolation
- Flexible connections
- Acoustic treatment
- Approximate noise level
Commercial Exhaust Maintenance
A ventilation system is not a one-time installation.
It requires inspection and cleaning according to actual usage.
Daily or frequent checks
- Confirm the blower is operating
- Check unusual vibration or noise
- Inspect visible grease accumulation
- Keep the hood area unobstructed
Filter cleaning
Cleaning frequency depends on:
- Frying volume
- Tandoor use
- Wok cooking
- Operating hours
- Grease production
High-grease kitchens may need much more frequent filter cleaning than light cafés.
Hood cleaning
Clean external and internal hood surfaces using a method suitable for the material and grease load.
Duct inspection and cleaning
Grease accumulation inside the duct can increase fire risk and reduce system performance.
The inspection and cleaning schedule should be decided according to cooking intensity, system design and applicable safety requirements.
NFPA 96 includes specific sections on inspection, testing and maintenance of commercial cooking ventilation and fire-protection equipment.
Blower servicing
Check:
- Belt condition
- Bearings
- Motor
- Fan balance
- Vibration
- Grease deposits
- Electrical connections
Maintain service records where practical.

Frequently Asked Questions
How much does a commercial kitchen exhaust hood cost in India?
The price depends on dimensions, stainless-steel grade, thickness, filter design and installation. A small fabricated hood may begin around ₹15,000–₹35,000, while larger customised hood lines may cost ₹70,000–₹1,50,000 or more. Final pricing should be based on a written specification and site requirement.
How much does a complete restaurant exhaust system cost?
A basic system may cost approximately ₹35,000–₹70,000. A mid-size restaurant system may require ₹1 lakh–₹2 lakh, while a hotel, banquet or multi-cuisine system can exceed ₹3 lakh. These are indicative planning ranges.
What CFM is needed for a restaurant kitchen?
There is no single CFM value suitable for every restaurant. Airflow depends on hood type, cooking appliances, heat and grease load, hood dimensions, mounting height, duct resistance, filters and replacement air. Final sizing should be completed after reviewing the entire system.
Is make-up air necessary?
Commercial kitchens need a planned way to replace exhausted air. The exact system and quantity depend on the exhaust rate, building pressure, air conditioning, hood design and local requirements.
Can a domestic chimney be used in a restaurant?
Domestic chimneys are generally not designed for continuous commercial cooking, heavy grease loads or commercial duct systems. A food business should use a system selected for its cooking equipment, operating hours and ventilation requirement.
Is SS304 compulsory for the exhaust hood?
Not every project has the same material requirement. SS304 may be preferred in corrosion-sensitive, wet, visible or heavy-use areas. The final selection should consider food-service hygiene, moisture, cleaning, cooking load, budget and applicable project requirements.
Does the exhaust hood require filters?
Grease-producing cooking operations generally require an appropriate grease-removal arrangement. The suitable filter and hood design should be selected according to the cooking equipment and applicable standards.
Is fire suppression mandatory?
Requirements vary by building type, cooking operation, location and the local authority. Hotels, malls, institutional kitchens and high-risk cooking operations may have stricter requirements. Confirm with the relevant fire authority or project consultant before finalising the system.
How often should kitchen ducts be cleaned?
The frequency depends on grease production, cooking method, operating hours and inspection findings. High-volume frying, tandoor and wok kitchens generally require more frequent attention than low-grease operations.
Should the hood be installed before the cooking equipment?
The hood and cooking equipment should be planned together. Final installation sequencing depends on the site, but the equipment line, hood size, utility points and duct route should be confirmed before fabrication.
Plan the Exhaust Before the Kitchen Is Finished
A commercial kitchen exhaust system should not be treated as a decorative stainless-steel canopy.
Its performance depends on the interaction between:
- Cooking equipment
- Hood
- Filters
- Blower
- Ducting
- Replacement air
- Building pressure
- Cleaning access
- Fire safety
The best time to plan ventilation is before the cooking line, ceiling and duct route are permanently fixed.
Do not ask only, “What is the hood price?” Ask, “What complete system will safely capture and discharge the heat, smoke and grease produced by my kitchen?”
