Reinders Extraction Systems supplies all parts necessary for air extraction and filtration systems. We supply ducting, connections, reductions, sprouts and many more parts. 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. All our parts feature two unique benefits: they are very easy to install and deliver a solid pipework.

The Reinders Extraction Systems expertise

Reinders Extraction Systems

Reinders Extraction Systems supplies industrial exhaust installations, from the smallest extractor, to the largest filter cabinet and all the pipes, bends and valves in between. We can supply complete installations as well as individual parts. 

Our company has been around since 1910, and with our decades of experience we can give you expert advice on what the best extraction options are for your application.

Pipework: Easy installation, solid components

Our pipework up to Ø 500mm is characterized by its bead edge. This rounded edge has two major benefits:

  • Quick & easy assembly
    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.
  • Increased stiffness of the pipework
    The bead edge provides a much greater stiffness of the components and thus a far more solid pipe network with a longer lifespan.

Our pipework of Ø 800mm and larger is equipped with flanges.

Dust Extraction Pipework

Reinders can supply all conceivable parts that are used 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 does everything possible to make them as fire-resistant and explosion-proof as possible. Our products all comply with fire, explosion and safety regulations. 

Below is a list of parts we can supply. Looking for a part that is not on the list? Just ask us! We can supply nearly everything you need for industrial dust extraction.

Ducting Options: Round or Square

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
  • Galvanized or stainless steel
  • 1 m or 1.5 m length
  • Standard thickness: 0.8 mm (other thicknesses available upon request)

Square or rectangular channels are available in all sizes.

Dust Extraction Branches

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 Extraction Systems manufactures many different diameters, lengths for both round and rectangular ducting.

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 a suitable extraction hood. 

Extractor Fan Pipe

When installing dust extraction ducts, air flow must be taken into account in order to avoid the formation of turbulence in the extraction duct. 

Because turbulence can result in:

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

To prevent turbulence, Reinders Extraction Systems 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 very 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.
