Capturing at source
The most efficient way to capture air pollution in industry is as close to the source as possible. One avoids extracting large air volumes and above all the pollutant is not spread around in the room. This is what we refer to as “captur-ing at source”. Contaminants may be in the form of solid waste, dust, fume, mist and gas, produced, for example, in a metalworking process such as welding or grinding or in a handling process involving foodstuffs or chemicals. The extraction of exhaust fumes from car and truck engines is another typical example of solving problems at source.
Optimal solutions
Capture at source technology can be divided in two main categories:
• High vacuum = high speed extraction - low air volume
• Low vacuum = low speed extraction - high air volume
Sometimes we also refer to mid vacuum. This technique is applied in applications with light dust and shavings where the extraction capacity can be adjusted in order to save energy and reduce noise.
Nederman masters the whole spectra of vacuum technologies – from high to low vacuum. Therefore, we always can offer the most practical and cost-effective solution from our extensive range of products and systems. See also product guides on pages 8-11
High, mid or low vacuum – we master them all
High vacuum Low vacuum
Type of contaminant Airborne particles and solid waste Airborne particles
High vacuum
High vacuum, i.e.high speed extraction is done very close to the source or directly on the source. Typical applications are floor and machine cleaning, extraction from high speed tools such as grinders, cutters, sanders and suction from welding guns. The high vacuum technology allows solutions with flexibility over the whole working area combined with low air volumes.
Low vacuum
Low vacuum, i.e low speed extraction, allows capturing the pollutants at a greater distance due to the higher air flow. Low speed capturing is recommended for extraction of fumes, dust exhaust and other airborne particles. The extraction is carried out with extraction arms, exhaust nozzles, enclosures and canopies over machines.
The consequences of fires or explosions can be extensive and include rupture of afilter systems and recirculation of contaminated air with subsequent health risks and damage to plant. Although it is impossible to completely eliminate the risk of creating explosive mixtures, it is possible to reduce the risk of ignition and the effects of an explosion.
Directives for explosive applications
Within the EU, harmonized regulations have been in force since 1994, whereby employers are required to assess the risk of creating an explosive atmosphere in their production environments. Two other directives became mandatory in 2003 concerning explosive applications:
European Directive 99/92/EC/ATEX 137
This directive states that it is the responsibility of the user/ employer, to assess and classify the working environment. Thus, the risk of working in a potentially explosive atmosphere is the first criterion that has to be examined when choosing an extraction arm, filter or fan for any operation or process. The Nederman Risk Assessement Report will be the basis for the choice of products for which we, as manufacturer and supplier, will be responsible with regard to product compliance.
European Directive 94/9/EC/ATEX 100a
The European Directive 94/9/EC applies to the equipment manufacturers and harmonizes the technical and legal standards to which equipment for use in potentially explosive atmospheres is manufactured.
Nederman offers a range of Ex approved and marked products which are manufactured according to these requirements.
Risk Evaluation Form
The Nederman Risk Assessment Report (published on www.nederman.com), filled in by the customer, qualifies and quantifies the pertinent aspects of the production process, including, for example, the type and composition of the dust, the air flow requirements and the extraction system. We then recommend suitable equipment for the described application and guarantee its functionality with respect to the information supplied. Each project is individually documented in detail for future reference. Where dust is concerned, assessment is based on the risk of combustible dust being present in the atmosphere, classified on a scale from continuous presence of explosive concentrations to unlikely presence with limited short term risks. A similar scale is used for assessing the risks involved when dealing with gases.
Applications with explosive risks
What is a dust explosion?
An explosion is the rapid combustion of a mixture of dust and gas – usually air. Dust concentrations have to be high enough to feed the combustion chain reaction.The speed of the resulting shock wave is less than 340 m/s. If the mixture is highly turbulent there could be a more violent explosion and the shock wave could reach 2,000 m/s, causing extensive damage. Potential ignition sources are also important to assess. For example, sparks from grinding or welding, electrical sparks, and glowing material from the work process.
Examples of different types of explosive dust
Organic dust in the food industry: Baking flour, soup powder, spices, flavouring Synthetic organic dust: Powder paint, plastic, grinding dust Metal dust: Aluminium, magnesium, titanium, and chromium Pharmaceutical dust: A great number of powders

Generally speaking, low vacuum products and systems are used for extraction purposes where the air is contaminated with small, light and low velocity particles that can be regarded, for design purposes, as acting like a gas. Welding fume and baking flour dust are good examples of potentially hazardous substances that are best dealt with at source. This means that:
• their removal uses high volumes of air, 600 – 2000 m³/h • they are extracted via large diameter ducting at relatively
low speeds, around 10 – 25 m/s
• the pressure drops that have to be overcome are low, normally in the region of 1 – 3 kPa.
Typical applications for low vacuum solutions
• engineering processes such as welding • grinding and oil mist recycling
• food and pharmaceutical processes involving the handling of powders or chemicals. In these last instances there is often a latent explosion risk and specially adapted prod-ucts are available for dealing with such situations.
Bench top applications
Bench top extraction of fumes, vapours and light dust is often used in small-scale or light industrial applications such as soldering and gluing or working with solvents. Schools, laboratories, health clinics and medical research institutions are some of the workplaces that can benefit from these solutions. Detailed product information about bench top extraction can be found in the Nederman Product Catalogue.
NEDQuote
NEDQuote is a powerful design and calculation program, and a unique tool in which different set-up scenarios for arms, filters and fans can be investigated. See Nederman Customer Support for further details.

How to dimension
In the dimensioning example it is assumed that only 50% of the extractors are in operation simultaneously. The calculation then provides the approximate maximum airflow and vacuum requirements so that a suitable fan can be chosen. If a careful analysis of frequency of use is carried out, and dampers and inverter equipment are installed, it will often be possible to further reduce the size of the fan.
Dimensioning the ducting
The following simplified dimensioning procedure can be used for any extraction system:
1. Draw a simple sketch
Mark the proposed locations of the extractors, the filter (if any) and the fan. Note the length of the ducting and how many 90° bends are required. In this example it has been assumed that there are 5+5+5+5+5 m of ducting and 5 bends.
2. Choose extraction arms
Two 4 m and two 2 m NEX HD arms have been chosen.
3. Calculate the total airflow required
The arms will be used for heavy welding, requiring 1200 m³/h per arm. This means a potential maximum airflow of 4800 m³/h if in operation simultaneously. In practice, however, it is most probable that only 2 arms will be in operation at the same time, which means that the design airflow rate will only be 2400 m³/h (1200 m³/h + 1200 m³/h = 2400 m³/h, 50% use).
4. Calculate the required vacuum
Determine the required vacuum by carrying out the following steps:
a) Read off the pressure drops for the 4 m and 2 m NEX HDs working at 1200 m³/h. The model requiring the greatest vacuum will provide the dimensioning value. In this case, it is 340 Pa for the 4 m arm.
Note! Only one arm shall be calculated.
b) Add 5 Pa for every metre of duct, measured from the arm furthest away from the fan. 20 metre of duct in this example.
c) Add a further 15 Pa for every 90° bend. 5 bends in this example. d) Add 1200 Pa for the filter, FilterMax F, single module. (With a filter area of 60 m² and an operational load of 40 m³/m²h the filter unit can handle an airflow of 2400 m³/h). See page 25 for suitable filter cartridge. The required vacuum is: 340 + (20 x 5) + (5 x 15) + 1200 = 1715 Pa A= Filter B= Fan
5. Choose the fan
x= airflow y= static pressure
The required fan capacity is 2400 m³/h at 1715 Pa. A suitable fan is the NCF 30/25.
In this example, the following duct dimensions are required:
Airflow, m³/h Duct, mm From arm 1 to arm 2 1200 200 From arm 2 to arm 3 2400 250 From arm 3 to arm 4 2400 250 From arm 4 to filter 2 400 250 From filter to fan 2 400 315 From fan to outlet 2400 315
The connection from the extractor arm to the main duct should always be at least 160 mm in diameter.
For more precise dimensioning of ducting, please contact your supplier.
Note!
When using the NEDQuote design and calculation program, different installation set-ups can be quickly investigated to determine an optimum solution.
Always check that there is a sufficient incoming air supply to the workplace. In a common ducting system, with one fan serving several extractors, there is a risk of temporary fluctuations in suction capacity and pressure drop, but these problems are easily overcome by using dampers and frequency controlled fan.

The Nederman range of extraction arms covers a wide variety of applications for use in both explosive and non-explosive environments. The different models meet the requirements of the relevant European Directives, such as Directive 98/37/EC concerning safety of machinery and Directive 94/9/EC, commonly known as the ATEX 100a Directive, concerning the use of equipment and protective systems in potentially explosive atmospheres.
Before an extraction arm is chosen, it is the responsibility of the user/employer, according to European Directive
99/92/EC, or ATEX 137, to assess and classify the working environment. The resulting classification will be the basis for the choice of arm for which Nederman, as manufacturer and supplier, will be responsible with regard to product compliance.
All Nederman arms are highly flexible, and simple to position, extend and retract. Different attachments are available for wall, ceiling or extension bracket mounting as well as a number of accessories, including hoods and dampers to improve efficiency.

The first step towards effective and safe removal of fumes, gases and dust from the workplace is choosing the most suitable extraction arm. The next step is to consider how the contaminants are to be removed from the extracted air so that it can be returned to the atmosphere or recycled without negative impact on the environment or workplace. These situations are often governed by stringent regulations with significant economic penalties if they are not observed. Filter systems must therefore be chosen to fulfil a number of basic requirements and the first main division of types is with regard to their use in explosive or non-explosive en-vironments. The production environment must be assessed and classified according to current directives. The filters in this handbook are for stationary installation; there is also an extensive choice of mobile filter units, see the Nederman Product catalogue for further details.
The Nederman FilterMax System
This is a modular system of filter units designed to deal with all types of fume and dust resulting from mechanical working or handling of a wide range of materials.
If additional workplaces are added to the extraction system, increasing airflow requirements, then new modular sections can be easily added.
There is also a compact stand-alone unit, C 25, for low vol-ume applications where space is limited.
Dimensioning example
Light welding requires handling a load of 50 m³/m²h. In a FilterMax DF with a single module the filter area is 72 m², which means that it can filter 3600 m³/h (50 m³/m²h x 72 m²). This is equivalent to the volumes of extracted air from 3 or 4 welding stations in simultaneous operation. It could be advantageous to consider a twin module set-up to ensure sufficient capacity and longer cartridge life.
Note:
The welding shop in the example might have a total of 15 welding stations, but with a usage frequency of 15%, the filter suggested will be sufficient.
When designing filter systems it is always important to take into account additional parameters such as the temperature of the extracted air at the inlet, the required filtration ef-ficiency, possible recirculation of air and potential safety hazards.
Nederman FilterMax C25
For further information see the Nederman Product Cata-logue.
Nederman FilterMax F 30, 60 and 90
The filter handles the air polution from metal industries as well as non explosive dust from other industries. Integrated pre-seperator for coarse particles, sparks, etc. A wide range of cartridges for different purposes are available. Protection class IP54. In- and outdoor installation.
Nederman FilterMax DF 40, 80 and 120
The filter handles the air polution from metal industries as well as non explosive dust from other industries. A wide range of cartridges for different purposes are available. Pro-tection class IP54. In- and outdoor installation.
Nederman FilterMax SFC
FilterMax SFC gives increased safety against release of dangerous dust into the atmosphere. If the filtered air is re-circulated a FilterMax SFC is vital to maintain a safe work environment. In combination with a pressure switch the FilterMax SFC can work as an emmission alarm as well as a safety filter. FilterMax SFC can be used as a heavy duty general filter cabinet in applications such as vehicle exhaust or fine dust. One FilterMax SFC module filters the air from one FilterMax F or FilterMax DF module. The maximum capacity is 4000 m³/h, at heavy loads this is reduced down to 2000 m³/h. For general filtration of dust or fume the capacity is 2000 m³/h. The FilterMax SFC cabinet can be equiped with straight inlets or a combinations of 90° and straight inlets.
Nederman FilterMax DX 3000, 6000 and 9000
Designed for extraction of dry powder or dust with explo-sion risk applications or if exploexplo-sion protection is demand-ed accordingly to the ATEX directive. Ndemand-ederman’s Dustline serie includes FilterMax DX and extraction arms and fans for explosive environments. Food, medical or chemical in-dustries are likely users for this application. Protection class IP65.

Filter Cartridges
A number of different types of filter cartridges are available to deal with the contaminants. These are chosen depending on the source of the contaminant and the required degree of filtration. The type and intensity of the operations will determine the life of the cartridge, typically around 6000 hours of continual use. Filter cartridges are chosen depending on specific filtration requirements defined by particle characteristics and required efficiency.Cartridges are cleaned using powerful, pulsed shockwaves. The DF, F and DX units are fitted with automatic control systems for cleaning during and after operation. All FilterMax filters are available for indoor and outdoor use (except the C25 – indoor use only).

Dealing with oil mist
Oil mist is the aerosol that is often formed when oil is used as a coolant/lubricant during the machining of metal com-ponents. The mist comprises drops of oil, or oil and water emulsion. It is well known than prolonged and repeated exposure to oil products can be detrimental to health, which means that good ventilation must be ensured under all working conditions. Precipitation of oil mist on machinery, equipment and the workplace floor can be both detrimental and dangerous.
Mineral oil-based metalworking fluids are known as neat cutting oils or straight oils. They normally contain a number of undisclosed additives that can affect the viscos-ity of the oil. Emulsions normally contain 5 – 10% water-soluble oil and 90 – 95% water.
The Nederman range of oil mist filters NOM is designed for use in conjunction with machining work where emul-sions are used as the coolant/lubricant. They can also be used in the metalworking press industry. Contact Nederman for further information.
If straight oil is used the load must be moderate and limited to 8 – 100 mg/m³ in the aerosol phase. The viscosity of the coolant and degree of contamination will also affect the ef-ficiency of the filter system and its working life.
Coolant viscosity ranges and suitability
NOM Oil Mist Filters have a unique filter concept using one of the most advanced filter media on the market offering trouble-free operation and low maintenance costs. 99.97% filtration efficiency is guaranteed when a HEPA filter is used. A high level of filtration combined with a gravity drip self-cleaning function ensures protection for both personnel and equipment.
The filter units are simple to install, even in limited spaces. All models are machine-mountable. Compact or stand-alone models are available. In processes where oil smoke frequently occurs, the NOM Oil Mist Filter can be used to handle the oil mist deriving from swarf and chips created, for example, by CNC machines.

Recommended capacity
Investigate the routines to get full information regarding number of machines operating at the same time, size of machines,working hours a day (shift) and the cycle time. Calculate the airflow capacity from a typical situation For frequently openings of the door (manually handling of tools, item, etc) an increased airflow is required in the opening period due to increased open areas.
For automatic machines with normally closed doors it is necessary to delay opening of the door.
It is of primary importance to generate well balanced under-pressure so the oil-mist is removed and the bigger droplets of oil or emulsion stay back in the machine for recycling. Recommended air velocity 0.2 m/s through closed machines
Example:
Scrap openings and other openings and gaps in a closed machine might give an area like 1.0 m².
1.0 m2 x 0.2 m/s x 3600sek = 800 m3/h
A totally open machine needs a column hood.
Recommendation for emulsions
Pay attention to the viscosity (viscosity >200mm²/s, bal-ance the airflow carefully) Make sure the filter never is running with clean air through the filters. Never leave the dirty filters unused for a longer period time. If filter is left unused or running with clean air, water will dry out from the emulsion which will crystallize on the filter surface,and might block the filter. (Nedermans filters can be cleaned with lukewarm water and dishing detergent like Fairy, if necessary)
Recommendations for straight oil
Applications with straight oil and high workload need a well balanced down time period for at least 2 x30 min/24 hours for draining the filters.
Nederman NOM 4
The NOM 4 is designed for single CNC machines with limited oil mist, enclosed cabinet.
Nederman NOM 11, NOM 18 and NOM 28
These filters are designed for applications with need for larger airflow capacities. In all metal fabrication with oil mist troubles, these filters will fit into a central system, connected to each machine. All units are equipped with pressure gauge for control of filters as well as a indication for need of cleaning (self draining).

Recommended installation
During operation with closed door the airflow can be reduced, i.e. with a motorized damper. Before the end of the cycle the airflow can be increased by opening of the damper. The reduced airflow will reduce the amount of extracted oil mist and oil vapors. The damper control could be connected to a dedicated output from the machine control system or from a signal from the coolant pump system.
The position of the outlet in the CNC machine should be protected from direct oil injections, as from the chuck. Install adjustable dampers for each machine.

Nederman fans are designed for use in all types of industrial processes and ventilation systems, and are constructed for both indoor and outdoor use. The choice of fan depends on the pressure drops and flow requirements of the system in question. In some cases it might be more economical to choose a number of smaller fans instead of one central fan for space reasons or when loading conditions are difficult to specify.
The first design criterion is whether or not the environment can be subject to explosions. The production environment must be assessed and classified according to current directives.
The size of the fan will be determined by the vacuum required to overcome the pressure drops in the extraction arms, filters and ducting and by the airflows required to maintain the correct transportation speeds of the contaminated air. To reduce power costs and increase efficiency, the use of fan starters, dampers and fan inverters is recommended. These will minimize the required airflows in the system and optimize the fan speed at different work loads.
Sound absorbers are available for use with NCF range fans. Contact your local Nederman office or Nederman sales representative for details.

Airflow control
Fans designed to handle full-time use of all extraction arms in an installation risk being over-dimensioned. This is because the frequency of use at each workplace is generally significantly lower than a theoretical maximum design load. To deal with these situations there are Nederman solutions that offer considerable savings in power and maintenance costs. Noise levels will also be reduced if airflows can be kept to a minimum.
Nederman Fan Starter/Fan Contactor
The cost-effectiveness of the extraction system can be improved if the fan only operates when work is being carried out. A fan contactor can be activated via a sensor clamp attached to the earth cable of welding equipment or a switch in the hood.Installing a fan starter: • reduces power costs
• minimizes the volume of heated air extracted air from the premises
• allows a stop delay of up to 5 minutes to ensure extraction of remaining dust and fumes

Nederman Fan Inverter
The Nederman Fan Inverter detects the pressure changes in the extraction system and adjusts the speed of the fan accordingly.
The fan inverter:
• ensures the correct airflow for any given combination of extractors in use
• reduces noise levels that would otherwise occur if the system were under-loaded
• activates the frequency controller via a timer, switching on and off depending on working hours
The inclusion of manual or automatic dampers in the extraction system will also significantly improve its overall efficiency and reduce running costs. The diagram shows typical power savings in an extraction system when a fan inverter is installed.
