The “Eliminator” range of, extremely robust, acoustic hoods have been designed to facilitate reliable two-way speech communications in high ambient noise locations. The “Eliminator” acoustic hood is manufactured from rot/vandal resistant glass re-enforced polyester which requires no routine maintenance and is light in weight. The enclosure shell colour is impregnated within the manufacturing process and is therefore protected against ultra violet radiation or other agents that would affect the throughlife colour stability.
