Summary of industrial air duct types: Spiral round, EI45, square and tapered – Characteristics and practical applications

SUMMARY OF INDUSTRIAL AIR DUCT TYPES: ROUND, SPIRAL, EI45, SQUARE AND TAPERED – CHARACTERISTICS AND PRACTICAL APPLICATIONS

In HVAC (Heating, Ventilation, and Air Conditioning) systems, choosing the right type of ductwork plays an important role in ensuring performance, energy savings, and safety for the building. Below is a summary of common types of industrial ductwork: spiral round duct, EI45 fireproof duct, square duct and duct cone, along with the characteristics and practical applications of each type.

1. SPIRAL ROUND AIR DUCT

Characteristic:

  • Structure: Spiral round duct is designed in a round cylinder shape with spiral lines around the outside, usually made from galvanized iron or stainless steel.

  • Advantage:

    • High aesthetics: The rounded design minimizes joints, creating a modern look.

    • High performance: Reduce pressure loss, increase air transmission efficiency.

    • Easy to install: Light weight, easy to transport and install.

Application:

  • Civil engineering: House, office, commercial center.

  • Industrial: Factory, workshop, industrial park.

  • Air conditioning system: HVAC, ventilation, dust extraction.

2. FIREPROOF AIR DUCT EI45

Characteristic:

  • Structure: Consists of 4 layers:

    • Inner layer: Galvanized steel with minimum thickness of 0.75mm.

    • Insulation: Prevent the spread of fire.

    • Fireproof class: Protect the insulation from high temperatures.

    • Outer layer: Protection against impact and corrosion.

  • EI45 Standard: Ensures integrity and insulation for 45 minutes in case of fire.

Application:

  • Exhaust system: Especially vertical exhaust pipes in high-rise buildings.

  • Fire protection and prevention: Areas requiring high fire safety standards.

  • Public works: Shopping mall, hospital, train station.

3. SQUARE AIR DUCT

Characteristic:

  • Structure: Square or rectangular shape, usually made from galvanized iron or stainless steel.

  • Advantage:

    • Space saving: Easy to install in narrow spaces.

    • Easy to connect: Suitable for accessories such as air valves and air vents.

    • High efficiency: Even air distribution.

Application:

  • HVAC System: Air conditioning, ventilation in buildings.

  • Industrial: Factory, factory.

  • Civil engineering: Office, commercial center.

4. AIR DUCT REDUCER

Characteristic:

  • Structure: Accessories used to connect two duct sections of different sizes, can be round-round, round-square, square-square.

  • Advantage:

    • Smooth air flow transition: Minimize pressure loss.

    • Easy to install: Flexible design, suitable for many types of air ducts.

    • Increase aesthetics: Neat, professional connection.

Application:

  • HVAC System: Connecting duct sections in the air conditioning system.

  • Industrial: Factory, factory.

  • Civil engineering: Office, commercial center.

5. CHOOSE THE RIGHT TYPE OF AIR DUCT

Choosing the right type of ductwork depends on many factors such as:

  • Technical requirements: Pressure, air flow, fire protection standards.

  • Installation space: Area, shape of space.

  • Budget: Investment costs, operating costs.
