Nederman has stationary and mobile solutions for extracting and filtering dust and fume from welding, cutting and surface preparation
Welding, cutting and grinding generates dust and fume that harm personnel and make vehicle and premises dirty. Wherever it is a viable solution, it has been proven that extraction at source is the most effective and efficient method of capturing and removing welding and similar fumes. Using this method, the risk of the welder or operator being subject to hazardous fumes is minimised.
The necessary components to achieve proper source capture of welding fumes are an easily positioned fume extractor with a well-designed hood, proper airflow through the fume extractor and a conscientious welder who will position the hood in a manner that will draw hazardous fumes away from his or her breathing zone and avoid to spread the smoke in the premises.
Welding dust and fume extraction at-source with arms
Nederman has a wide range of extraction arms in different designs. Full flexibility and easy to position. Arms can be fitted to both stationary and mobile vacuum and filter units.
Extraction Arms
The most effective solution for removing and mitigating welding fume is close or at-source extraction. The arms, sometimes called snorkels, vary in diameter and length, can be positioned from 6 – 15 inches from the welding fume generator and typically have an extraction volume of 500 – 1,000 CFM. The variation in arm design and style is so there is a model that can be applied to different applications where the arm needs to fit within a small work space or instances where the arm must be able to reach to distances of 20 feet or more. Nederman has a wide range of welding fume extraction arms in different designs with full flexibility and are easy to position to fit many applications. Arms can be fitted to both stationary and mobile vacuum and filter units.
Surface preparation
Surface preparation with an abrasive sandblaster is the operation of forcibly propelling a stream of abrasive material (i.e glass beads, korunt, steel grit, etc) against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants such as paint or rust.
One of the main challenges in any surface preparation operation with a sandblaster is to keep the blasting media from contaminating the surrounding work environment. Surface preparation needs to be carried out in an enclosure. This is most often done in a dedicated blasting room, separated from other operations, so work pieces need to either be moved to and from the blasting room, or encapsulated, leading to increased operating costs.
Surface preparation with vacuum sandblasters
The Nederman vacuum sandblasters are productivity boosters, thanks to the design of the vacuum head along with the continuous, non-pulsing stream of the blasting abrasive. You'll cover larger surfaces faster and save money with less downtime and abrasive costs. With the vacuum sandblasters you can operate continuously and re-use the same abrasive several times, depending on the type of abrasive. During the surface preparation the vacuum sandblaster collects the dust in plastic bags. Efficient pre-separation of abrasive with automatic reverse air jet filter cleaning provides for long lasting filters.
