It is designed for the efficient spray application of Glass fibre Reinforced Concrete (GRC). Both cement/sand slurry and glass fibre are projected from the same nozzle helping to ensure good distribution. The glass fibre roving is cut to length within the rear chopper mechanism. Compressed air propels the chopped fibres through the atomiser body nozzle. Simultaneously, slurry is conveyed to the nozzle from the pump and is emitted from an annulus surrounding the fibre.
