Concentric Spray Head
The Concentric Spray Head is used for the most popular method of GRC production: Traditional Hand Spray, in which cement/sand slurry and glass fibre are projected from the same nozzle, ensuring efficient and even distribution.
The precise engineering and innovative design of the gun streamlines the production process. Glass fibre roving is fed through the gun and cut to length within the rear chopper mechanism whilst 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.
Designed with convenience in mind, the Concentric Spray Head is lightweight and simple to maintain, featuring flexible airlines and a remote start/stop function for the spray station with other controls located on the boom. A water flush facility – controlled from the overhead boom – is fitted as standard.
A spare parts pack including all the main wearing parts is included as standard.
