The vacuum box serves to extract the urea solution that is used for aftertreatment of exhaust gases in selective catalytic reduction (SCR catalyst).
With the special vacuum extraction system, the process can be performed by one person and irrespective of location.
A vacuum is created and stored in the vacuum box via a venturi nozzle with connection to the workshop compressed air supply.
The extraction process is carried out by removing the venturi nozzle, coupling the extraction hose and opening the inlet valve.
Extraction volume approx. 9.5 litres.
