Function

The NEX HD is very heatresistant and has a high extraction capacity. It is
therefore suitable to be used for extracting welding fumes from heavy welding
processes and dust from metalworking as for example grinding.
CAUTION!
The NEX HD must not be used for extracting such dust- or fume-airmixtures
which could affect the product materials, see Figure 2.
WARNING! Risk of explosion.
The NEX HD must not be used for extracting dust- or fume-airmixtures in
explosive environments.
