What it is
The NT 50/1 K Kärcher is a machine in the Professional Vacuum Cleaners category from Kärcher, the world leader in professional cleaning technology, headquartered in Winnenden (Germany). The NT 50/1 K wet and dry vacuum cleaner is ideal for quickly removing large quantities of liquids or fluids in construction or industry thanks to its discharge pump.
A commercial vacuum cleaner is a heavy-duty machine for dry or wet and dry dirt, used for cleaning offices, industrial premises, laboratories and construction sites.
What it is for
Used for dust extraction at source, keeping both the workpiece and the workshop air clean, for extracting chips and shavings from machines and for cleaning workplaces and communal areas.
How to use it
Choose the filter according to the dirt, fitting a HEPA filter or one of the appropriate class where fine or hazardous dust is present. Connect a hose and tool suited to the surface and work in even passes; do not pick up liquids with dry-only models. Change the bag or empty the container before it is full and clean the filter to maintain suction.
