Transport: filtration and cleaning solution

Dust extraction and cleaning of production areas in the aerospace, automotive and rail industries

Metal processing involves methods that generate a large amount of dust and fumes that can make the atmosphere in production workshops unbreathable and polluted.

For companies in the industrial automation, mechanical, machining, boilermaking, metalworking, welding, casting and steelworks sectors of the aeronautical, automotive and rail industries, protecting the health of employees by minimising exposure to dust and fumes is a fundamental, daily challenge.

Our expertise

Metal processing (welding, brushing, melting, machining, forging, grinding, sanding, polishing, etc.) as well as assembly stations generate dust and fumes that can cause respiratory problems for operators, or even serious complications, such as those caused by Chromium VI.

Suction of these contaminants, dust and fumes on these different processes, but also the cleaning of production areas (cleaning floors and machinery) improve the working conditions of operators, as well as reducing the risk of explosion by complying with ATEX zoning.

Nos équipements de dépoussiérage

A wide range of dust extraction equipment

To address all of the problems faced by companies in the automotive, aeronautics and rail industries, CATTINAIR designs and offers a wide range of industrial dust extraction systems (in compliance with ATEX regulations).

These dust extractors are installed to ensure continuous suction on production equipment, but they are also used to process filtration air from centralised cleaning installations (extraction unit).

Expert in "turnkey" engineering

The installation of industrial dust extraction systems, or sometimes ventilation systems, is the best way to address air quality issues within automotive, aeronautics and rail sectors. After a personalised and in-depth process study, our project managers develop specific and ergonomic dust extraction systems that capture contaminants at source: smelting fumes, welding fumes, metal dust, oil mist, etc.

For all metal dust that has accumulated in and around the production tool. Our centralised vacuum extraction solutions capture the contaminants by means of cleaning accessories (suction attachments, brushes, pipes, etc.) connected to vacuum extraction hoses and outlets. The extraction points are installed directly in the workshop to enable the thorough cleaning of production areas and keep the industrial environment clean.

General ventilation systems can be used in addition to an extraction at source system and can also remove heat at the heat production source.

A comprehensive offer

Commissioning of installations by our project managers who helped design the installation.

Monitoring of proper functioning and measurement of air speeds and pressure losses of each machine and at different points of the suction collectors, motor intensities, as well as sound levels which are included in the technical file and certify compliance with the regulations.

Our Service Department offers original spare parts, upgrading and preventive maintenance contracts.

CHROMIUM VI or hexavalent chromium and its compounds

In the workplace, inhalation is the main route of exposure to chromium VI. It is considered carcinogenic by the CIRC (WHO cancer research agency) (Group 1). Related cancers are lung cancer, cancer of the nasal cavities and sinuses.

In the work environment, the occupational exposure limit values for hexavalent chromium are set at 1µg/m3 for 8-hour exposure limit (Decree no. 2012-746) and 5µg/m3 short term exposure limit (STEL) (1st July 2014).

Dust of mineral origin (silica, asbestos, iron, zinc, cobalt, tin, etc.) and vegetable origin (bagasse, cotton, cereals, flour, etc.) provide numerous and varied routes of exposure in the workplace. This dust may come directly from the raw materials used (in powder form in particular) and are released during their production, transportation storage or implementation (extraction, crushing of mineral ores, flour production, manufacture and use of plastic materials, etc.).

They are also produced during the processing of finished or semi-finished products (metal machining, sawing, sanding, grinding of wood or synthetic materials, waster grinding…) or during demolition and cleaning operations.

The occupational exposure limits apply to all forms of dust (marble, dust, etc.). Article R. 4222-10 of the French Labour Code.

8-hour time-weighted average

  • total dust = 10 mg/m3 of air
  • respirable dust = 5 mg/m3 of air

Dust can cause explosions. Solutions are available to reduce this risk which must comply with the ATEX Directive.
