Extraction hoods
Optimal large area suction
Our sheet steel extraction hoods ensure optimum removal of all emissions in a wide range of machining processes. We adapt our three types of extraction hoods for robotic use, for circular booth grinding/welding/cutting and with whirlwind extraction individually to the respective task in the operational process.
Robotor suction hoods
For automated processes
VALCO has been manufacturing extraction hoods for automated work processes for many years. Our robot exhaust hoods are made of welded steel sheets in galvanized or painted finish and can be ordered with single-flow nozzles and baffles on request. For optimal capture of smoke and dust, we offer the possibility of additionally suspending the sides with slats.
What are the challenges of smoke extraction for robotic operation?
Welding robots require a large radius of movement, which poses a problem for the use of conventional extraction hoods: Spot extraction is hardly possible and the extraction effect of conventional technology decreases too much after a few centimeters distance.
Our solution: Capture the smoke at robot workstations over as large an area as possible. Due to the hot air movement during welding, it is sufficient to extract the smoke above the robot. Lateral suction elements are only required here in the event of cross-flow in the working area.

Extraction hoods for round booths for grinding, welding and cutting.
We are also happy to manufacture custom products according to your specifications. For example, the extraction hoods for circular booths for grinding, welding and cutting.
The suction hood shown in the picture functions as a co-rotating grinding and welding booth for round components.
Adapted to your task as a special design, extraction elements from VALCO impress with their clean processing and precise functions. Special designs of extraction hoods as well as standard housings are available from us made of galvanized sheet steel or with a painted surface. According to your requirements we manufacture extraction hoods with manual or electric drive.

Whirlwind Hoods
For effective extraction in the working area
We manufacture whirlwind hoods from VALCO made of sheet steel with curved or straight back wall. The whirlwind exhaust hoods are powder-coated according to RAL or can be made of stainless steel on request. Widths are possible from 750 mm to 6,000 mm. The whirlwind hood is equipped with an internal swirl tube. The inflow runs parallel to the longitudinal axis of the suction hood. The end faces of the suction hood are closed including the cylinder part.
How does a whirlwind hood work?
Due to the two opposing suction surfaces (swirl tube) in the suction hood, a vortex is created with a small amount of air, resulting in uniform collection over the entire hood opening.

What are the health hazards of smoke and dust?
In addition to welding fumes, toxic and/or carcinogenic gases can also be generated during welding work, such as ozone, carbon monoxide or nitrous gases (NO, NO2 ,NOX) or hydrogen chloride during brazing and other hazardous substances.
Inhaled grinding dusts may cause skin irritation, sensitization, eye irritation and respiratory diseases.
If hazardous emissions cannot be avoided by technical process modifications, the dust must be completely collected at the point of origin, extracted and safely removed from the work area. (see TRGS)
