The limits for bitumen vapors and aerosols in the processing of hot asphalt are a regular subject of discussion. JOSEPH VÖGELE AG has been offering its customers extraction and ventilation solutions for a number of years. These route hot asphalt vapors and aerosols away, significantly reducing the exposure of paver and screed operators.
Note: The ventilation systems offered by VÖGELE differ in their design depending on model series. The pictures show the system on the SUPER 1900-3(i) and SUPER 2100-3(i) pavers by way of example.
The ventilation system extracts the vapors via the intake ducts and directs them away from the crew area. The suction effect is provided by a specially designed centrifugal fan located inside the machine. The intake is located directly above the conveyor discharge point. From there, via an exhaust pipe behind the operator's platform, the extracted aerosols and vapors are mixed with fresh air across the paver's roof and discharged.
