Aspiration ductwork is the backbone of any efficient dust and chip extraction system – it is the ductwork that ensures airflows reach the filter correctly and energy-efficiently from every processing point. Elister measures, calculates, designs and installs aspiration ductwork solutions for woodworking companies across Estonia.

Key benefits

  • Precise design: calculating air volumes and pressures ensures the fan serves the entire system efficiently
  • 3D drawings: a full-scale 3D design provides a clear overview of the entire route before installation
  • Suitable material for every environment: steel, stainless steel or spiral duct as needed
  • Comprehensive service: our team installs, calibrates and tests the system
  • Audit of existing systems: we measure actual airflows, identify bottlenecks and offer concrete solutions
  • Retrofit installation: we also install into existing production halls, taking your production schedule into account and minimising downtime
  • Diagnostics: we measure actual air velocities and flow rates using an anemometer or Pitot tube

How the design process works

  • Mapping of air volumes – the extraction requirement of each work point is determined precisely
  • Pressure and resistance calculations – the total resistance of the ductwork is calculated to select the fan capacity
  • 3D design – a full-scale 3D drawing before installation
  • Selection of suitable material – according to the substance being conveyed, the temperature and the working environment
  • Installation and calibration – installing, configuring and testing the system

What aspiration ductwork consists of

Complete aspiration ductwork is more than straight pipes. The system typically consists of straight pipes, bends and arcs, T- and Y-branches, transitions, dampers and valves for flow control, cleaning hatches, as well as fixings and seals. Each component affects the total resistance of the system and thus the energy consumption of the fan. See the selection of aspiration ductwork components and put together your quote.

Materials and dimensions

The material is chosen according to the substance being conveyed, the temperature and the working environment: galvanised steel for general dust and chip extraction, stainless steel in damp or corrosive environments, and spiral duct for flexible connections. The pipe diameter and wall thickness depend on the air volume and the abrasiveness of the material – we calculate these according to your machinery, rather than offering a standard solution.

Why correctly designed ductwork matters

Aspiration ductwork must keep the air velocity within a range where dust and chips remain suspended throughout the entire route. Too slow a flow allows material to settle in the pipe and causes blockages; too fast a flow increases energy consumption and accelerates wear of the ductwork. The correct diameter, smooth bends and low total resistance keep the fan energy-efficient and the extraction power consistent at every work point.

Where aspiration ductwork is used

Aspiration ductwork is the backbone of dust and chip extraction in the woodworking industry (sawing lines, CNC machines, sanding and finishing) as well as in the paper and printing industry. If you need an overview of a complete system – ductwork, filters, silos and design –, see the complete aspiration systems solution.

Common questions about this product.

Frequently asked questions

Can you install the extraction ductwork in our existing production facility without interrupting operations?
Yes, we offer retrofit installation into your existing production facility, taking your production schedule into account and minimising downtime.
Which piping materials do you offer?
We offer solutions made of steel, stainless steel or spiral tube according to the substance being transported, the temperature and the working environment.
Can you evaluate the performance of our current dust extraction system?
Yes, we perform audits of existing systems, measure actual airflow rates, identify bottlenecks and provide concrete solutions.
How do you ensure that the fan has sufficient capacity for the entire system?
We perform pressure and resistance calculations, where the total resistance of the piping is calculated to select the fan capacity.
Can I see how the piping will fit into our hall before installation?
Yes, we prepare a full-scale 3D drawing that provides a clear overview of the entire route already before installation.
What diameter of aspiration pipe is suitable for our machines?
The pipe diameter is selected according to the air volume of each working point and the material being transported. We measure and calculate the required diameter based on your machinery park to ensure that the suction power is sufficient and uniform at every point.
Do you also offer piping components separately?
Yes. In addition to complete design and installation, individual components are available from us – pipes, elbows, branches, transitions and gate valves. See the selection on the aspiration ducting components page and request a quote.
How fast must the air move through the ductwork?
Fast enough to keep dust and chips suspended throughout the entire routing and prevent them from settling in the pipe. The exact transport velocity depends on the material and is determined during the design calculations.
Is the piping suitable for both the wood and paper industries?
Yes. We design aspiration ducting systems for both the woodworking industry (sawing lines, CNC, sanding, finishing) and the paper and printing industry, selecting the material and dimensions to suit each environment.
