Exhaust air ducts are essential in construction, ventilation systems, and HVAC installations. Whether you’re a contractor, engineer, or homeowner, knowing the latest prices helps in budgeting and procurement. In this guide, we provide an updated exhaust air duct price list for the year 2024 in the Philippines, including galvanized steel, aluminum, PVC, and insulated ducts. We’ve sourced data from reputable suppliers and hardware stores to ensure accuracy.
1 What is an Exhaust Air Duct?
An exhaust air duct is a crucial component in ventilation and HVAC (Heating, Ventilation, and Air Conditioning) systems, designed to remove stale air, pollutants, moisture, and heat from enclosed spaces. These ducts ensure proper air circulation, maintaining indoor air quality (IAQ), temperature control, and safety in residential, commercial, and industrial buildings. In the Philippines, where humidity and heat are major concerns, exhaust ducts play a vital role in preventing mold growth, reducing odors, and improving energy efficiency.
2 Types of Exhaust Air Ducts
Exhaust ducts come in different materials and designs, each suited for specific applications:
Galvanized Steel Ducts – The most common type, known for durability and fire resistance. Used in commercial kitchens, factories, and HVAC systems.
Aluminum Flexible Ducts – Lightweight and easy to install, ideal for residential exhaust systems (e.g., bathroom vents, range hoods).
PVC Ducts – Corrosion-resistant and affordable, often used in laboratories, hospitals, and chemical exhaust systems.
Spiral Ducts – Made from galvanized iron (GI) or stainless steel, these provide high airflow efficiency and are used in industrial settings.
Insulated Ducts – Wrapped with fiberglass or foam to prevent condensation and heat loss, commonly found in cold storage and HVAC systems.
Fire-Rated Ducts – Designed to withstand high temperatures, used in fire-prone areas like commercial buildings and parking garages.
3 Key Uses of Exhaust Air Ducts
Kitchen Ventilation – Removes smoke, grease, and odors from commercial and home kitchens.
Bathroom & Toilet Exhaust – Eliminates humidity to prevent mold and mildew buildup.
Industrial Air Extraction – Expels harmful fumes, dust, and chemicals in factories and workshops.
HVAC Systems – Maintains balanced airflow in offices, malls, and hospitals.
Smoke & Fire Safety – Fire-rated ducts help contain and remove smoke during emergencies.
4 Why Are Exhaust Air Ducts Important?
Health & Safety – Reduces indoor air pollutants (CO2, VOCs, allergens) that can cause respiratory issues.
Moisture Control – Prevents dampness, which leads to structural damage and mold growth.
Energy Efficiency – Proper ventilation reduces AC workload, lowering electricity costs.
Compliance with Building Codes – Philippine regulations (e.g., NBCP, DOLE standards) require proper exhaust systems in workplaces and high-occupancy buildings.
Odor & Contaminant Removal – Essential in restaurants, hospitals, and laboratories where air purity is critical.
Choosing the right exhaust air duct depends on factors like environment, airflow requirements, and budget. Whether for a home, restaurant, or factory, proper duct installation ensures cleaner air, better temperature regulation, and compliance with safety standards.

5 Factors Affecting Exhaust Air Duct Prices
Material Type – Galvanized steel is cheaper than stainless steel but less corrosion-resistant.
Thickness – Thicker ducts (0.7mm vs. 0.5mm) cost more but last longer.
Diameter/Size – Larger ducts (e.g., 12-inch vs. 4-inch) are more expensive.
Supplier Location – Prices in Metro Manila may differ from provincial rates.
Brand & Quality – Premium brands (e.g., Yazaki, Ducttech) may charge higher.

Notes on Unit Price Inclusions, Exclusions & Considerations
✅ What’s Included in the Price?
The unit prices provided in the table generally cover:
Base Material Cost – The price per meter or per unit for the duct itself (e.g., galvanized steel, PVC, aluminum).
Standard Sizing – Prices are based on common diameters (e.g., 4-inch, 6-inch, 8-inch) and thicknesses (e.g., 0.5mm, 0.7mm).
Supplier Markup – Retail pricing from hardware stores and online marketplaces.
❌ What’s NOT Included?
Additional costs that may apply:
Installation Labor – Hiring technicians or welders for ductwork setup.
Fittings & Accessories – Elbows, reducers, dampers, clamps, and connectors.
Insulation (if not pre-insulated) – Additional thermal or acoustic insulation.
Shipping/Delivery Fees – Especially for bulk orders or remote locations.
Taxes & Custom Duties – For imported materials (e.g., stainless steel ducts).
⚠️ Key Considerations When Budgeting
Price Fluctuations – Costs may change due to metal price volatility (e.g., steel, aluminum).
Brand Variations – Premium brands (e.g., Yazaki, Ducttech) may cost 10–20% more.
Location Differences – Metro Manila prices may be higher than provincial rates.
Bulk Discounts – Contractors can negotiate lower rates for large orders.

Recommendation
For precise budgeting:
Request a formal quotation from suppliers, specifying:
Duct material, thickness, and dimensions.
Quantity needed (per meter or per piece).
Delivery and installation terms (if applicable).
Example:
*”A 0.7mm GI duct priced at ₱850/meter may cost ₱1,200/meter after adding insulation and labor.”*
