The Top Components of a Ducting System Your Workshop Might Need

An efficient ducting system is a fundamental requirement for any workshop or industrial setting. It plays a crucial role in ensuring the smooth flow of air, gases or liquids, serving purposes such as ventilation, exhaustion and transportation. 

Various parts work harmoniously within a workshop to create an optimised ducting system. Understanding the critical elements of such a system is essential for workshop owners and managers to make informed decisions about their installation and maintenance. 

From the primary ducts that act as conduits for airflow to the auxiliary components that regulate and control the movement of substances, each piece plays a vital role in the system’s overall performance. 

Why might you need ducting systems?

Ducting systems serve a variety of purposes and are essential in numerous applications. Here are some common reasons why you might need ducting systems:

  1. Ventilation: Proper ventilation is crucial in any workspace to remove stale air, odours and contaminants. A well-designed ducting system ensures continuous fresh air and maintains a healthy and comfortable environment for workers.
  2. Heating, ventilation and air conditioning: They are integral to heating, ventilation and air conditioning (HVAC) systems. These units regulate temperature, humidity and air quality within a building. Ducts distribute conditioned air from HVAC to different areas, allowing for even temperature circulation and efficient climate control.
  3. Air exhaust: In industrial settings, they remove hazardous gases, fumes and airborne particles generated by various processes and equipment, ensuring a safe working environment. 
  4. Dust and particle collection: Ducting systems with dust collectors, such as cyclones or bag filters, capture and transport solid contaminants from the workspace.
  5. Fume extraction: Certain industries, such as welding, chemical processing or laboratories, produce harmful fumes and vapours. Ducting systems equipped with fume extractors capture and remove these substances at the source.
  6. Process exhaust: Many manufacturing processes generate heat, moisture or byproducts that must be expelled. Ducting systems efficiently transport these substances to designated areas, preventing heat buildup, moisture damage or contamination of the surrounding environment.
  7. Energy efficiency: By minimising leaks, optimising insulation and utilising efficient parts, these pieces of equipment can help conserve energy, reduce operating costs and promote sustainability.
  8. Sound control: They can incorporate acoustic attenuators or silencers to minimise noise levels generated by airflow or equipment. These components absorb or redirect sound waves, creating a quieter and more comfortable working environment.
  9. Air distribution: Ducting systems distribute air from centralised sources to different areas or workstations within a building. This is particularly relevant in large industrial spaces or commercial facilities where uniform air distribution is necessary for occupant comfort and efficient equipment operation.
  10. Environmental control: They also control environmental factors such as humidity, airborne contaminants or specific temperature requirements in specialised settings like cleanrooms, laboratories or server rooms. 

The top parts of a ducting system

A properly functioning ducting system relies on various essential components. Among these, attenuators, spiral ducting and reducers are critical in ensuring optimal airflow, noise control and efficient connections within the system. Learn more about them.


Duct attenuators are designed to reduce the noise levels produced by the airflow passing through the ducts. To achieve this, they incorporate sound-absorbing materials, such as acoustic foam or mineral wool.

As the sound waves travel through the attenuator, they are absorbed, weakened or reflected, reducing overall noise levels.

Spiral ducting

Spiral ducting is a popular choice for ductwork due to its efficiency, durability and ease of installation. It comprises a continuous, spiral-wound metal strip that forms a rigid and smooth duct.

Its smooth interior surface minimises air resistance, reducing pressure losses and energy consumption. The spiral design provides structural integrity, making it suitable for high-velocity airflow systems. 

Additionally, spiral ducting is quick to install, requiring fewer joints and connections than rectangular ductwork. It is commonly made of galvanised steel or aluminium, ensuring longevity and resistance to corrosion.


Duct reducers are components used to connect ducts of different sizes or shapes. They facilitate efficient airflow without causing turbulence or pressure losses. 

This device is particularly useful when integrating various equipment or components with different ducting requirements. They can be either concentric, where the ducts maintain the same centreline, or eccentric, where the ducts have offset centrelines. 

Other essential components

In addition to attenuators, spiral ducting and reducers, several other parts are integral to a ducting system. These include:

  • Ductwork: The primary channels that transport air or substances throughout the workshop. Depending on the system’s specific requirements, they can be rectangular, round or oval.
  • Dampers: Devices installed within the ductwork to regulate or control the airflow. They can be manually operated or automated, allowing for adjustable airflow rates.
  • Elbows and bends: Curved sections of ductwork used to change the direction of airflow around obstacles or corners within the workshop.
  • Grilles and registers: Visible components installed at the end of ducts or on walls and ceilings, providing openings for air to enter or exit the workshop.
  • Insulation: Material applied to the exterior surface of ducts to control heat loss or gain and prevent condensation.
  • Expansion joints: Flexible connectors that accommodate thermal expansion and contraction of the ductwork, preventing damage to the system.
  • Access doors: Doors installed at strategic locations along the ducts, allowing for system inspection, maintenance or cleaning.
  • Air filters: Devices installed at the intake points of the ducting system to trap dust, allergens and contaminants present in the incoming air, ensuring improved indoor air quality.

Investing in quality components and ensuring regular maintenance and inspection of the ducting system is crucial. By doing so, workshop owners can not only maximise the longevity and performance of the system but also contribute to the overall success of their operations.
