Supply air diffusers are essential components in HVAC (Heating, Ventilation, and Air Conditioning) systems, ensuring proper air distribution in residential, commercial, and industrial spaces. If you’re a contractor, engineer, or property owner planning an HVAC project, knowing the latest prices helps in budgeting and procurement. In this guide, we provide an updated supply air diffuser price list for the year 2024 in the Philippines, including different types, materials, and trusted suppliers.
What is an Air Diffuser?
An air diffuser is a crucial component in Heating, Ventilation, and Air Conditioning (HVAC) systems, designed to distribute conditioned air evenly throughout a room while maintaining optimal airflow, pressure, and comfort. Unlike simple vents or grilles, diffusers are engineered to reduce drafts, minimize noise, and improve air mixing, ensuring efficient temperature control and indoor air quality. Whether in homes, offices, hospitals, or industrial spaces, air diffusers play a vital role in maintaining a healthy and comfortable environment.
Types of Air Diffusers
Air diffusers come in various designs, each suited for specific applications:
Ceiling Diffusers – The most common type, installed in suspended ceilings for centralized air distribution. They come in round, square, or linear designs and are ideal for offices and commercial buildings.
Linear Slot Diffusers – Slim, elongated diffusers that blend seamlessly into modern interiors. They provide aesthetic appeal while delivering uniform airflow, often used in hotels and high-end spaces.
Jet Nozzle Diffusers – Designed for high-velocity airflow, these are used in large spaces like auditoriums, airports, and warehouses where long-throw air distribution is needed.
Floor Diffusers – Installed at ground level, these are common in underfloor air distribution (UFAD) systems, providing efficient cooling in open-plan offices and server rooms.
Adjustable Louver Diffusers – Feature movable blades to control airflow direction, making them ideal for spaces requiring targeted ventilation.
Perforated Face Diffusers – Have small holes for dispersing air gently, reducing drafts and noise, often used in hospitals and laboratories.
Decorative Grille Diffusers – Custom-designed diffusers that enhance interior aesthetics while maintaining functionality, popular in luxury homes and boutique hotels.

Uses of Air Diffusers
Air diffusers are essential in:
Residential HVAC Systems – Ensuring even cooling/heating in homes.
Commercial Buildings – Maintaining air circulation in offices, malls, and hotels.
Healthcare Facilities – Providing clean, draft-free airflow in hospitals and clinics.
Industrial Spaces – Ventilating factories, warehouses, and data centers.
Green Buildings – Supporting energy-efficient airflow in sustainable designs.
Why Are Air Diffusers Important?
Improved Air Distribution – Prevents hot/cold spots by evenly dispersing air.
Energy Efficiency – Reduces HVAC workload by optimizing airflow, lowering electricity costs.
Noise Reduction – Designed to minimize turbulence and whistling sounds from ducts.
Enhanced Air Quality – Helps filter and circulate air, reducing dust and allergens.
Aesthetic Integration – Modern diffusers blend into ceilings and walls without disrupting design.
Choosing the Right Air Diffuser
When selecting an air diffuser, consider:
✔ Room Size & Ceiling Height – Larger spaces may need high-velocity diffusers.
✔ HVAC System Type – Centralized vs. split systems require different diffuser designs.
✔ Material & Durability – Aluminum is lightweight and rust-resistant, while stainless steel suits harsh environments.
✔ Airflow Requirements – CFM (Cubic Feet per Minute) ratings determine efficiency.
Air diffusers may seem like small components, but they significantly impact comfort, energy efficiency, and air quality. Whether renovating a home or designing a commercial HVAC system, choosing the right diffuser ensures optimal performance and long-term savings.
