Duct Reducer – Precise and durable air flow transition connection

DUCT REDUCER – PRECISE AND DURABLE AIR FLOW TRANSFER CONNECTION

In any ventilation or air conditioning system, maintaining and adjusting air flow is always a key factor that determines overall performance. In particular, duct cone is one of the indispensable accessories that helps connect pipes of different sizes smoothly, accurately and optimize gas transmission efficiency.

So what is a duct reducer? Why does it play such an important role in the HVAC (Heating, Ventilation and Air Conditioning) system? And why should you choose a duct reducer product? Sao Viet HVAC? Let's find out the details through the article below!

1. WHAT IS A DUCT REDUCER?

Duct reducer (also known as reducer, reducer, transition pipe) is an accessory used in the duct system to connect two duct sections of different sizes (in diameter or cross-section). The reducer helps ensure that the air flow is smoothly transferred from a large duct section to a small duct section (or vice versa) without causing significant pressure loss.

Depending on technical requirements, the cone can be in the form of:

  • Round cone – round

  • Round - square reducer

  • Square reducer – square

  • Square - round cone

Each type is designed according to its own standards, suitable for the system layout and specific usage purposes.

2. FUNCTION AND ROLE OF REDUCERS IN THE AIR DUCT SYSTEM

✅ Connect pipe sections with different cross-sections

During the HVAC system design process, changing the size of the air duct is necessary to adjust the pressure, air flow, or due to construction space limitations. Reducers help to connect smoothly between pipe sections, avoiding air leakage.

✅ Optimize air flow and direction

The cone helps to direct the airflow smoothly, minimizing airflow conflicts, pressure loss and noise.

✅ Increase aesthetics and professionalism for the system

Neat, precise connections contribute to the technical and aesthetic perfection of the entire ventilation and air conditioning system.

✅ Easy to install and remove for maintenance

With standard design, the reducer allows quick construction, and is easy to replace or upgrade when necessary.

3. STRUCTURE AND MATERIALS OF AIR DUCT REDUCERS

Depending on the environment and conditions of use, the cone can be made from different materials:

Galvanized Steel (GI):

Most popular, good rust resistance, reasonable cost, suitable for most civil and industrial works.

Stainless steel 201/304:

Excellent corrosion resistance, suitable for high humidity environments, food processing areas, pharmaceuticals...

Aluminum:

Light, easy to construct, good thermal conductivity - often used in civil air conditioning systems or areas requiring low loads.

4. COMMON CLASSIFICATION OF REDUCING CONES

Concentric reducer:

The axes of two pipe sections coincide, used when it is necessary to change the cross-section without changing the position of the air flow.

Eccentric reducer:

The two non-coordinated pipe sections help to guide air to avoid obstacles or adjust the air flow direction, suitable for low ceiling constructions or complex technical systems.

5. APPLICATION OF REDUCING CONES IN PRACTICE

  • ✅ Central air conditioning system (VRV, Chiller, AHU...)

  • ✅ Basement and technical floor ventilation system

  • ✅ Industrial exhaust system

  • ✅ Air ducting in factories, workshops, clean rooms

  • ✅ Ventilation system for restaurant and hotel kitchens
