Commercial Vehicle Extraction
Typical Commercial Exhaust Extraction System
Capturing fumes 'at source' is the most efficient way of eliminating commercial / HGV vehicle exhaust fume problems which are normally found within manufacturing facilities, service workshops and VOSA testing stations etc.
Although operating with larger engines to that used in passenger cars, the increased exhaust gases temperatures that are normally generated during vehicle servicing can still be accommodated with standard temperature hoses with an increased extraction airflow.
