Many industrial processes generate airborne dust and particles that can be hazardous to human health. The most effective way to remove dust is to extract it at the source, before it reaches the breathing zone. If dust and particles do spread in the facility, proper housekeeping equipment is needed to ensure a cleaner and healthier work environment.
Dust and particles are generated in many different ways. Typical sources are dust from cutting, grinding, sanding, handling of powders in food, and pharmaceutical industries. Textile, wood and composite working may also release dust and fibers that are harmful to human lungs and can cause allergic reactionsor even worse by penetrating the skin.
There are at least four important types of solutions for handling dust and particles:
- extraction arms
- on-tool extraction
- cleaning applications
- general air purification
In addition to dust and particles that is hazardous to the human health they can also create explosions. Read more about combustible dust and how to avoid it.
Extraction arms are especially suitable for light airborne dust and fumes and cover a wide variety of applications. A typical application is when handling different types of powders or fumes. Welding applications, bakeries, laboratories are some of many examples where arms are a good solution. The advantage with arms are that they are fully flexible in all directions and easy to position, thus covering a large working area and/or serve several working stations.The arms are connected to a fan and dust collector system removing the contaminants from the extracted air so that it can be returned to the atmosphere or recycled without negative effects.
Nederman offers a wide range of arms in different designs, arm lengths, hose diameters and various hood designs. 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.
For applications like cutting, grinding and sanding, on-tool extraction is the most efficient way to capture dust and particles. The dust is extracted at high speed directly from the tool, thus avoiding extracting large air volumes and above all the pollutant is not spread around in the room. On-tool solutions also are also flexible, allowing the operators to work over larger areas.
Nederman offers a wide range of on-tool extraction kits (Attachment kit) for more several hundred of tools used for cutting, grinding, sanding etc available on our website. Attachment kits are available for both electric and pneumatic tools.
Dust spread easily in industrial facilities. While far from all of them are outright hazardous, they are not exactly healthy or desired either. Some dust is even combustible. Taking care of the actual dust or waste is usually not difficult and the overall tendency is clear: Industrial housekeeping is becoming an increasingly common phenomenon, which also ties in with a general, global development where industries and facilities are becoming safer and more sustainable. The solutions Nederman offer range from compact equipment like small industrial vacuum cleaners – to greater, stationary systems with specific maintenance accessories.

General air purification
Air purification solutions can be a complement to at source extraction and will keep the background concentration of welding fumes and other dust particles as low as possible. The Nederman FMC Cartridge Filter is ideal for the removal of fine dusts and fumes that can be irritating and harmful. It has a compact design and slide out filter removal system for easy maintenance.
Wood dust is one of the most common combustible dusts that Nederman routinely provides industrial dust collection solutions for. Dust collectors do not only need to efficiently remove and filter dust, the entire system must be designed correctly to meet ATEX and NFPA standards, to protect your workers and facility. To learn more about these hazards, see combustible dust handling.
