1️⃣ Why Kitchen Ventilation Matters

Benefits of a well-designed ventilation system:
✅ Controls heat and humidity
✅ Removes grease-laden vapors and smoke
✅ Improves indoor air quality
✅ Enhances kitchen staff comfort and productivity
✅ Helps meet health and safety regulations
✅ Protects building surfaces and equipment

2️⃣ Key Components of a Commercial Kitchen Ventilation System

✅ 1. Exhaust Fans

Industrial exhaust fansare the backbone of kitchen ventilation:

• Extract hot air, grease vapors, and smoke

• Maintain negative pressure to contain contaminants

• Installed on walls, ceilings, or rooftops

Fan typesto consider:

• Wall-mounted exhaust fans

• Roof-mounted centrifugal fans

• Inline ducted exhaust fans

✅ 2. Air Curtains

Air curtainsare often installed above kitchen doors or service entrances:

• Prevent hot/cold air exchange

• Block dust, insects, and outdoor pollutants

• Help maintain a clean environment between kitchen and dining areas

✅ 3. Make-Up Air Systems

Forbalanced airflow, kitchens may requiremake-up air units:

• Supply fresh, conditioned air

• Offset the volume of air exhausted

• Prevent negative pressure issues in the building

✅ 4. Ductwork and Accessories

• Grease-rated ducting with smooth interior surfaces

• Fire-rated insulation where required

• Access doors for cleaning and inspection

• Proper duct sizing to minimize airflow resistance

3️⃣ How to Choose the Right Ventilation Solution

Consider:
✅ Kitchen size and layout
✅ Type of cooking equipment (grills, fryers, ovens, woks)
✅ Local building codes and fire safety requirements
✅ Desired air changes per hour (ACH)
✅ Noise level considerations
✅ Energy efficiency targets

4️⃣ Common Mistakes to Avoid

❌ Under-sizing exhaust fans → insufficient airflow
❌ Ignoring grease management → duct fire hazards
❌ Poor make-up air design → negative pressure problems
❌ Using non-rated duct materials → code violations
