If you run a restaurant, cafe, hotel kitchen or cloud kitchen in Riyadh, commercial kitchen ventilation standards decide whether you pass your health and civil defense inspections, how safe your staff are, and how long your cooking equipment lasts. Grease, heat, smoke and steam all need a properly designed exhaust path, and inspectors across Saudi Arabia check it closely.
Most kitchen fires start in a dirty or undersized ventilation system, not at the stove. In this guide we break down the six commercial kitchen ventilation standards that matter most for food businesses in Riyadh: hood sizing, duct construction, exhaust airflow, make-up air, fire protection, and cleaning schedules. Each one follows internationally recognized practice (ASHRAE and NFPA 96) that local inspectors expect to see.
SheelTalab’s certified HVAC team installs, inspects and maintains commercial kitchen ventilation systems across Riyadh with 45-minute rapid dispatch and a 30-day golden warranty. Our Central HVAC & Ducted Systems service (350 SAR, was 450) covers inspection, coil cleaning, duct sanitization, airflow balancing, filter upgrades and motor lubrication.

Why Commercial Kitchen Ventilation Standards Matter in Riyadh
Riyadh’s restaurants run hot. Grills, charbroilers, fryers and woks pump out grease-laden vapor for 12 to 16 hours a day. A kitchen that follows commercial kitchen ventilation standards pulls grease and heat out efficiently, keeps cooking odors out of the dining room, and keeps the kitchen slightly negative so smoke never drifts to customers.
Missing these standards brings failed municipal and civil defense inspections, higher fire risk, overheated staff, grease damage to ceilings and ductwork, and closures after surprise visits. The six standards below are your checklist to stay compliant and safe.
1. Size and Position Your Exhaust Hood Correctly
The exhaust hood is the heart of the system. It must overhang the cooking equipment by at least 6 inches on the front and sides (3 inches minimum on a wall side) so rising grease vapor is captured instead of spilling past the edge. For charbroilers and solid fuel equipment, extend the front overhang to 18 to 24 inches.
Mount the hood 6 to 7 feet above the cooking surface. Too high and the thermal plume spreads before reaching the filters; too low and it interferes with cooking. Listed hoods tested to UL 710 allow lower exhaust rates than unlisted hoods, which saves fan energy over time.
Canopy hoods vs proximity hoods
Wall mounted canopy hoods are the most common choice for restaurant lines in Riyadh because they capture high plumes from grills and fryers. Proximity (backshelf) hoods sit lower and suit light to medium duty appliances, but codes do not allow them for heavy duty equipment. Add end panels to island canopies so dining room AC drafts do not blow grease vapor past the hood edge.
2. Build Grease Ducts to Code
Grease ducts carry hot, flammable vapor, so they follow strict construction rules. Use welded steel of adequate gauge, never flexible duct, and slope horizontal runs slightly so liquid grease drains toward the hood or a grease collection point. Keep the duct at a minimum transport velocity of 1,500 to 2,000 feet per minute for cooking exhaust so grease does not settle inside the duct.
Clearances and access panels
Maintain proper clearance from combustible materials, or enclose the duct in a fire rated shaft where clearances cannot be met. Fit liquid tight access panels at every change of direction so cleaners can reach the full duct run. Grease residue inside an inaccessible duct is one of the most common inspection failures we find in older Riyadh kitchens. Pair this with our AC duct cleaning in Riyadh service to keep the whole air path sanitized.
3. Match Exhaust Airflow to Your Equipment
Every cooking appliance has a duty rating from light to extra heavy, and the exhaust rate must be sized for the highest duty appliance under the hood. For listed wall mounted canopy hoods, ASHRAE guidance calls for roughly 150 to 200 CFM per linear foot of hood for light duty, 200 to 300 for medium duty, 200 to 400 for heavy duty, and 350+ for extra heavy duty. Undersized fans leave grease in the air; oversized fans waste energy.
Measure, do not guess
The only reliable way to confirm airflow is with a digital anemometer or capture hood meter at the filters and duct takeoffs. During a SheelTalab commercial HVAC visit, our digital airflow balancing service measures every hood and branch, adjusts fan speeds and damper positions, and documents the readings so you have proof of compliance for your next inspection.
4. Supply Enough Make-Up Air
A kitchen exhaust fan pushes thousands of CFM out of the building. That air must be replaced, or the kitchen will run at severe negative pressure: doors slam, pilot lights flutter, and dining room air gets sucked through the kitchen. The standard rule is to supply make-up air equal to about 80 to 90 percent of the exhaust rate, keeping the kitchen slightly negative relative to the dining room but never starved.
Do not count on transfer air leaking from the dining room alone. Dedicated make-up air units, tempered for Riyadh’s heat, keep staff comfortable and stop your AC from working overtime. For the dining side, consider an AC maintenance contract in Riyadh so your comfort cooling stays efficient all year.
5. Fire Protection and Duct Clearances
Grease ducts must be protected by an automatic fire suppression system covering the hood, filters, plenum and duct collar. Never install fire or volume dampers inside grease ductwork, because a closing damper traps heat and grease with no escape path. Where ducts pass near combustible construction, use fire rated enclosures or listed grease duct wrap.
Civil defense inspectors in Saudi Arabia look closely at suppression coverage and duct enclosure details. SheelTalab coordinates hood, duct and suppression checks in a single visit so nothing is missed before your license renewal.
6. Clean and Inspect on a Fixed Schedule
Commercial kitchen ventilation standards require regular cleaning on a schedule set by cooking volume and fuel type: monthly for high volume operations using solid fuel or charbroilers, quarterly for moderate volume kitchens, and semi annual for low volume kitchens. Grease filters must be cleaned or replaced on schedule, belts and fan bearings checked, and the full duct run inspected for residue.
Keep a written log with dates and photos of every cleaning and inspection. For the full engineering reference behind these tables, see the ASHRAE kitchen ventilation design guide (doczz.net), which documents the hood sizing and airflow rate tables used worldwide.
