Donaldson Torit DCE Downflo Oval, Downflo Evolution
Traditionally it has been the norm to use wet collectors to extract overspray zinc dust. This is mainly due to the potential for explosion associated with zinc dusts, especially as the particle size can be quite fine.
In recent years Health & Safety Engineering has been providing dry dust extraction systems for zinc thermal spraying.
Zinc dust is still potentially explosive in the dry form, therefore the company takes a number of measures not only to prevent an explosion occurring, but also to minimise the effect of an explosion if it does occur.
