Fibres in the air we breathe count as a special form of dust consisting in inorganic or organic particles which are oblong in shape. Depending on their source, fibres are divided into natural and synthetic fibres. Natural fibres are all textile fibres and fibrous materials that are produced from plant or animal material without any modifications. They must be distinguished from synthetic fibres, which are synthetically produced and can be of almost any shape, thickness and length.
Hazards from fibres and fibre dusts
Fibres with a length of more than 5 µm, a diameter of less than 3 µm and a length-to-diameter ratio of more than 3:1 are defined as WHO fibres or respirable fibres, because they can deeply penetrate the respiratory tract.
The hazards of fibre dusts have become known from asbestos-related problems, but other artificial mineral fibres (AMFs) such as glass wool, slag wool, high-temperature wool or mineral wool — depending on their composition — also release fibres which are considered as risk factors for lung cancer. There is also an increased risk with textiles because they emit fibres and dust particles to the air, especially when humidity is low.
Requirements of fibre extraction systems
In Germany, special requirements apply for processing and disposing of fibres and fibre dusts, which can be found in the Technical Rules for Hazardous Substances (Technische Regeln für Gefahrstoffe, TRGS). Apart from their effective extraction, economically viable disposal or recovery should also be considered.
On the basis of an expert analysis of your specific requirements, we can determine whether an industrial-type vacuum cleaner or a dust filter can be used. The possibility to recycle fibres can also be considered when choosing the extraction systems.
Modular dust extraction
The Air-S-Line is part of the Air-Line family and has been developed with a focus on a modular design and the efficient extraction of moist and sticky dusts. Read more about its construction and functioning on the product page.
Dry dust extraction
The Air-P-Line is part of the Air-Line family and has been specially developed for the centralised extraction of dry and free-flowing dusts. Read more about its construction and functioning on the product page.
NOVUS offers a comprehensive product portfolio ranging from plug & play devices to customer-specific centralised or decentralised extraction systems, from best selling line to custom units and attachments.
Fibres and fibre dusts often occur when processing textiles. They also arise from work with paper, plastics and construction materials such as plasterboard, insulating material or weaving asbestos. Glass fibre fabrics are often used as temperature-resistant insulation for cables.
Extraction of fibres should fit the requirements of the respective industry and the amount of the materials to be extracted.
