Air duct system


A proper air duct system is crucial in an industrial environment, as it plays a significant role in maintaining energy efficiency and ensuring air tightness. Efficient ductwork minimizes energy losses by ensuring that conditioned air is effectively distributed throughout the facility, reducing the need for additional heating or cooling. This leads to substantial energy savings and lower operational costs. Moreover, an airtight duct system prevents leaks, which can compromise indoor air quality and disrupt the controlled environment necessary for industrial processes. By optimizing air flow and maintaining a consistent environment, a well-designed air duct system supports the overall efficiency, safety, and sustainability of industrial operations.

The duct system is suitable for particle transportation from woodworking, comfort ventilation, extraction systems for better working environment, plasma cutters, and specially designed ventilation plants where there is an extra demand for form, cleaning, colour and appearance.

  • Particle transportation from woodworking, such as saw mills, carpenters, furniture manufacturers and craft workshops.

  • Comfort ventilation.

  • Extraction systems for better working environment.

  • Plasma cutters.

  • Specially designed ventilation plants where you have extra demands for form, colour and appearance

There is always a risk of dust explosion in installations where finely-divided material is transported.

A dust explosion occurs when a critical mixture of finely divided material and air is ignited and burns rapidly with consequent rapid expansion and pressure rise. A common cause of ignition is a spark from electrostatic discharge. Dust and sawdust extraction installations must be designed to minimise sources of fire and explosion.

Industrial duct system

Anyone that in some way works in industrial environments knows this; industrial applications are special. The environment is tough and the demands are in most cases extremely high. This, in turn, places huge demands on every component delivered to the application.

  • Materials for Industrial Ducts
  • Galvanized steel Z275 0,9 – 3,0 mm
  • Zinkmagnesium ZM310
  • Stainless steel EN 1.4301 and EN 1.4404 0,8 – 5,0 mm
  • Black steel 1,5 – 5,0 mm
  • Aluminium AlMg3, 1,5 – 3,0 mm
  • Perforated plate can be galvanized or stainless
  • Flanges 3 – 15 mm, galvanized, stainless or black steel

Air tightness

Air tightness is key to energy reduction.
The major areas of energy consumption in buildings are heating, cooling and ventilation. An air tight ventilation system is key to lowering the energy consumption. Lindab is the first supplier in the world to offer ventilation ducts in the highest tightness class.

Materials, corrosivity, pressure classes

Materials, corrosivity, and pressure classes are critical factors in industrial ventilation systems due to their direct impact on durability, safety, and performance. By considering these factors, industrial ventilation systems can be tailored to meet specific operational demands, ensuring safety, efficiency, and longevity.
