The new Power-Sprays’ Concentric Spray Head is designed for the efficient spray application
of Glass fibre Reinforced Concrete (GRC). It is to be used with the new improved boom fitted
to Power-Sprays spray stations.
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.
Compressed air, supplied direct from the nozzle, atomises the slurry and the two materials
are projected as a composite.
A water flush facility, controlled from the overhead boom, is fitted as standard.
The new Concentric Spray Gun is lighter and the air-lines are more flexible making the gun easier to use. The Spray station can be remotely started and stopped from the spray gun but other controls are now located on the boom.
