Reinders Extraction Systems specializes in industrial extraction and filtration. We have been doing this since 1910. We also design sound-insulating cabins and supply piping.

The Reinders Extraction Systems expertise

Ducting for exhaust and filter systems

Reinders Extraction Systems supplies all and any parts necessary for air extraction and filtration systems. We supply ducting, connections, reductions, sprouts et cetera. 


Quick and easy to install ducting

Our pipework up to Ø 500mm is characterized by its bead edge. This rounded edge makes the pipes and fittings quick and easy to assemble. With the help of the QF-clamp, which is equipped with a quick release fastener, all pipes and fittings can be assembled without tools. Compared to other piping systems that often have a right-angled edge and narrow clamp bands that are tightened with a screwdriver, the time savings are considerable. In addition, the bead edge provides a much greater stiffness of the components and thus a solid pipe network with a longer life. Our pipework of Ø 800mm and larger is equipped with flanges.

Quickly order ducting

Send us an e-mail with a list of whatever your need, and we will quickly supply you with a quotation. All standard sized parts are always in stock and can be supplied instantly. Parts with custom dimensions are made in-house and can be manufactured in short periods of time. 

Reinders Extraction Systems supplies complete industrial exhaust installation, from the smallest extractor, to the largest filter cabinet and all the pipes, bends and valves in between. We manufacture, supply, install and maintain them! Our company has been around since 1910, and with decades of experience we can also give you good advice on what the best extraction options are for your application.

Dust extraction ducting

Reinders Extraction Systems produces both round tubes (pipes) and square ducts. For smaller diameters round tubes are usually used. For large air flows, square or rectangular ducts are common. Standard sizes for round tubes vary from:

  • ø100 mm up to ø400 mm
  • Standard galvanized, stainless steel also available
  • 1 m or 1.5 m length
  • Thickness: 0.8 mm as standard, other thicknesses also available

Square or rectangular channels are available in all sizes.

Dust extraction pipes

An industrial dust extraction installation may consist of many groups with many branches. All of these branches will have different lengths, depending on their position in the company / factory and the branches may have different diameters depending on the air flow that needs to be extracted. Reinders Luchttechniek manufactures many different diameters, lengths for both round and rectangular ducting

Dust extraction pipework

We can supply all conceivable parts that one uses for the piping of dust extraction. Certain components, such as explosion elbows, come with a certificate that indicates the quality and safety of the product. Because almost all fine dusts are explosive, it is important that fire and explosion hazards are taken into account when installing dust extraction piping. For its industrial dust extraction installations, Reinders Extraction Systems does everything possible to make them as fire-resistant and explosion-proof as possible. The separate parts which we install and which you can order separately from us also comply with fire, explosion and safety regulations. Below is a list of parts we can supply.

Extractor hood channel

For some industrial processes, just extracting air into the room is not enough. It is necessary to extract dust, fumes or welding smoke locally at the process or close to the machine. In such a situation, a flexible extraction arm with an extraction hood can provide a solution. Different processes require different extraction hoods. Depending on the process and what needs to be extracted, dust, fumes or welding fumes, Reinders Extraction Systems can recommend an extraction hood. These include:

  • Dimensions
  • Shape
  • Material
  • Amount of air to be extracted

Extractor Fan Pipe

When installing dust extraction ducts, air flow must be taken into account. One must try to avoid the formation of turbulence in the extraction duct. For turbulence gives:

  • More resistance for the fan
  • More explosion risk
  • More wear of parts in the piping overcome. 

To prevent turbulence, Reinders Luchttechniek can determine the correct pipe diameters and bend radius. This depends on the amount of air that needs to be moved. For a pipe with branches, for example a manifold, the pipe diameter will change several times because the air volume that flows through per hour after each branch is more than before. (Or less, depending on which way you look at it, of course.) In order to properly handle the additional air flows, Reinders Extraction Systems can customize the following components for your piping system:

  • T-pieces
  • Pants
  • Y-pieces
  • Double T-piece
    • Spruits / Manifold
    • Saddle piece

Exhaust duct

Many pipework and ducts are connected with flanges. However, for round pipes with small diameters, it is very easy to use QF piping, Quick-Fit piping. Around the pipes is a folded edge, the bead. With a clamp band, two pipes can be connected so quickly by pressing and clamping them together. Connect without tools, and quickly done! Clamp bands are available in the following sizes as standard:

  • Ø 100 mm up to Ø 700 mm
  • Larger sizes available on request

Pressure drop across a pipe

The pressure drop over a pipe is an important factor because, together with the amount of air to be moved, it indicates how large and how powerful the exhaust fan must be. For a straight pipe of a certain diameter where air flows through, the pressure drop is fairly simple to calculate. It depends on:

  • Medium, in this case air
  • Pipe diameter
  • Pipe length
  • Friction factor
  • Flow rate, volume of air per hour
  • Height difference over pipes

However, as soon as there are branches, gradients, bends, valves and filters in the pipework, the pressure drop calculation is more complicated. An estimate is made based on knowledge and experience. The fan that is installed is always slightly oversized. It takes into account unexpected pressure drop and the pressure drop that will increase over the filters.
