The limit values for bitumen vapours and aerosols produced when hot asphalt is processed are forever coming up for discussion. For years, JOSEPH VÖGELE AG has offered its customers a solution in the form of an extraction device/ventilation system. The result is that vapours and aerosols from the hot asphalt are re-routed, considerably reducing the exposure of operators of both pavers and screeds.
Note: the design of the ventilation systems supplied by VÖGELE differs depending on the series in question. The pictures show the system for the SUPER 1900-3(i) and SUPER 2100-3(i) pavers by way of example.
the ventilation system takes in the vapours via the intake ducts and routes them away from the vicinity of the operating team. The suction action is created by a radial fan developed specifically for the system and positioned on the inside of the machine. The intake is located directly above the discharge point of the conveyor. The extracted aerosols and vapours are mixed with fresh air and routed away from here over the roof of the paver via an exhaust air pipe behind the operator’s platform.
