    Fabric ducts

    FabricAir
    Fabric ducts are a type of supply duct system that is made from lightweight fabric material instead of traditional metal or plastic ductwork. The fabric is typically made of a durable polyester material, which allows for flexibility and easy installation. Fabric duct systems distribute conditioned air throughout a space by using small perforations or vents along the length of the ducts to evenly distribute airflow. The fabric material also helps to dampen noise and reduce energy loss due to insulation properties.
    • Material: Polyester fabric
    • Flexibility: Easily bendable and flexible
    • Installation: Simple and quick installation
    • Air Distribution: Even and uniform distribution
    • Perforations: Small holes or vents for airflow

    Spiral ducts are a type of supply duct system commonly used for HVAC (heating, ventilation, and air conditioning) applications. They are cylindrical in shape and constructed using a helical or spiral design, hence the name. These ducts are typically made from galvanized steel or aluminum and are known for their durability, high airflow capacity, and ease of installation.
    • Material: Galvanized steel or aluminum
    • Shape: Cylindrical, helical or spiral design
    • Durability: Strong and long-lasting
    • Airflow capacity: High, due to smooth interior surfaces
    • Installation: Easy and cost-effective

    Rectangular ducts

    HVAC engineers and designers
    Rectangular ducts are a type of supply duct system commonly used in HVAC (Heating, Ventilation, and Air Conditioning) installations. These ducts are rectangular in shape and are used to distribute conditioned air from the central air handling unit to various rooms or areas within a building. They provide an efficient and effective means of delivering air to different spaces.
    • Shape: Rectangular
    • Material: Sheet metal (typically galvanized steel)
    • Sizes: Various sizes available to meet different airflow requirements
    • Insulation: Can be insulated to reduce heat gain/loss and noise transmission
    • Pressure classification: Rated based on maximum pressure the duct can withstand

    Round ducts are a type of supply duct system commonly used in HVAC applications. As the name suggests, these ducts are cylindrical in shape and are primarily made from galvanized steel or flexible materials like aluminum or PVC. They are designed to distribute conditioned air from the HVAC unit to different areas of a building.
    • Material: Galvanized steel, aluminum, or PVC
    • Shape: Cylindrical
    • Size: Common sizes range from 4 inches to 24 inches in diameter
    • Installation: Installed either overhead or along walls
    • Airflow: Highly efficient in distributing airflow evenly

    Plenum ducts are a type of supply duct system commonly used in commercial buildings. They are typically made of sheet metal and are designed to distribute conditioned air from the HVAC system to different areas of the building. Plenum ducts are installed in the space between the structural ceiling or floor and a drop-down ceiling or raised floor, known as the plenum. The plenum serves as an air distribution chamber and allows for a more efficient and concealed ductwork installation.
    • Material: Sheet metal (galvanized steel or aluminum) is commonly used for plenum ducts.
    • Shape: Rectangular or square-shaped.
    • Insulation: Plenum ducts may be insulated to reduce heat transfer and minimize condensation formation.
    • Size: Available in various sizes, depending on the airflow requirements of the building.
    • Connection: Typically connected to the HVAC system through round or oval supply ducts.

    Sound attenuators, also known as silencers, are components used in HVAC systems to reduce the noise level produced by air movement within ducts. They are typically installed in the supply duct system to decrease sound transmission and create a more comfortable and quiet environment for occupants.
    • Sound reduction: Typically capable of reducing the noise level by 15-35 dB(A)
    • Construction: Made of acoustic material such as mineral wool or fiberglass
    • Shape: Common shapes include rectangular, circular, and flat-octagonal
    • Pressure drop: Creates a moderate pressure drop in the system, affecting airflow
    • Length: Available in various lengths depending on the required noise reduction

    Duct silencers are a type of supply duct system component designed to reduce noise produced by airflow in HVAC systems. They consist of sound-absorbing materials enclosed in a metal or fiberglass casing, and are installed within the supply ductwork to minimize noise transmission.
    • Noise Reduction: Typical noise reduction of 15-30 decibels (dB)
    • Material: Constructed with sound-absorbing materials like fiberglass or mineral wool
    • Casing: Enclosed in a durable metal or fiberglass casing
    • Shape: Rectangular or cylindrical, depending on the design
    • Size: Available in various sizes, ranging from small domestic installations to large commercial applications

More information on most popular type of supply duct system

When it comes to HVAC systems, the supply duct system is an essential component. It’s responsible for distributing conditioned air throughout a building, ensuring that every room is comfortable and properly ventilated. There are several types of supply duct systems available, each with its own advantages and disadvantages. The most popular type of supply duct system is the flexible duct system. It’s affordable, easy to install, and can be easily adapted to fit into tight spaces. However, it may not be as durable as other duct systems, and may require more frequent maintenance. Rigid duct systems, on the other hand, are more durable and can last longer than flexible duct systems. They’re ideal for large commercial buildings, but can be more difficult to install and may require more space. Another popular type of supply duct system is the ductless mini-split system. It’s a great option for retrofitting existing buildings or adding heating and cooling to new construction. However, it can be more expensive than other options, and may not be as energy-efficient. Ultimately, the type of supply duct system that’s best for a particular building will depend on a variety of factors, including the size of the building, the climate, and the budget. It’s always a good idea to consult with a professional HVAC contractor to determine the best option for your specific needs.
