AVD is applied as a mist. Particles of vermiculite in the mist are deposited on the surface of the burning fuel, forming a film on the fire. This film dries instantly and due to its high aspect ratio the platelet particles overlap and stick together creating a non-combustible oxygen barrier between the fire and the atmosphere.

AVD’s high-performance Lith-Ex extinguishers are designed to fight high-risk, limited-size fires. are suitable for confined spaces such as apartments, hotel rooms, vehicles, public transport, aviation, marine or special leisure and process areas, where in any case fires must be suppressed in their early stages before they develop into a fully established fire.
