Suction system for a gas extraction plant to protect health of mechanics and of all the workers in contact with motorcars, motorcycles and lorries. In fact, extraction gases produced by motorcars, motorcycles, lorries, buses or ground-moving means are a compound highly polluting and harmful to health, containing carbon monoxide (CO), unburned hydrocarbons (HC), nitrogen carbon monoxide and dioxide (NOx), sulphur dioxide and trioxide (SOx) and airborne particulates.
The gas extraction plant is a system capable, thanks to an extractor and a pipe, to extract polluting gas straight from the vehicle muffler terminal and to eject it outside the workshop.
In this case, our Technical Department decided to employ an extraction duct, because:
- once the pipe is connected to the muffler, the system follows the vehicle in motion during all revision phases;
- in case of several working decks, it is possible to optimize the number of extraction points depending on the actual workload.
This type of plant is therefore ideal for mechanical workshops with several workstations arranged in line, and with simultaneous low extraction.
Design stage involved sizing of the exact speeds of air flow in extraction and discharge ducts, with consequent calculation of the overall load losses depending on the path of the tubes and other components of the plant, all custom designed.
