Description

A duct connector is a fitting that joints two pieces of ductwork together. Duct connectors are available in a variety of materials, including metal, fabric, and plastic. Duct connectors are used in HVAC equipment in which fans and blowers are connected with them. They are also used in the connecting ducts in tight spaces. Connectors are also used in the connecting ducts that need to be able to expand and contract.\

• Reducing stress on ductwork
• Connecting ductwork that needs to be able to expand and contract

What is a duct connector?

All air duct installation for heating, cooling, or ventilation are attached to mechanical equipment containing a fan or bowler. Vibration, noises, and rattles resulting from the operation of the fan or bowler are transmitted into the metal ducts which carry the noises throughout the system. In order to isolate the vibration and noise to the source, an air-tight flexible joint, consisting of a fabric that is secured to sheet metal on both sides, must be inserted between the equipment and the ductwork. This flexible joint is called a “flexible duct connector”.

Application

Connecting HVAC equipment to ductwork:

This is the most common use for the duct connector. They are used to connect fans, blowers, and HVAC equipment to ductwork. This allows the equipment to be easily removed and replaced for maintenance.

Isolating noise and vibration:

Duct connectors can be used to isolate noise and vibration from HVAC equipment. This is important in applications where noise is a concern, such as hospitals, schools, and offices.

Making up for misalignment:

Duct connectors can be used to make up for misalignment in ductwork. This can be caused by settling, movement of the building, or other factors.

Reducing stress on ductwork:

A duct connector can be used to reduce stress on ductwork. This can be caused by the expansion and contraction of the ductwork due to temperature changes.

Connection flexible ductwork to the rigid ductwork:

Duct connectors can be used to connect flexible ductwork to rigid ductwork. This is often done in applications requiring flexibility, such as in ductwork that runs through tight spaces.

Item properties

1. Flexibility

The defining property of flexible duct connectors is their flexibility. They are constructed from a material that allowsthem to bend and conform to various shapes and spaces, making them ideal for installation where rigid ductwork is impractical or impossible

2. Ease to install:

Flexible duct connectors are generally easier to install than rigid ductwork. Their flexibility eliminates the need for complex cutting and bending techniques, making them suitable for DIY installations. This ease of installation reduces labor costs.

3. Adaptability to thermal expansion and contraction:

HVAC systems are subject to temperature fluctuations, causing ductwork to expand and contract. Flexible duct connectors can accommodate these thermal movements without compromising airflow or structural integrity.

4. Airtightness and leak prevention:

Flexible duct connectors are designed to provide airtight connections, preventing air leakage and maintaining system efficiency. This airtightness minimizes energy loss and maintains optimal system performance.

5. Durability and corrosion resistance:

Flexible duct connectors are manufactured from a material that balances flexibility and durability. Some flexible duct connectors are treated with anti-corrosion coatings to protect them from harsh environmental conditions.

Structure and material:

Flexible duct connectors consist of two layers. The inner layer is made of polyester or polyurethane. The fabric duct is spiral-wound or pleated to provide flexibility and strength. The outer is made of metal in which polyester layers are connected with the outer layer with the help of the clamps. This layer protects the inner layer from damage and provides insulation.
