The Downland PIIA Concentric Spray/chopper is widely regarded as the GRC industry ‘standard’ as it is well-balanced, easy to use and produces high-quality GRC on both open and intricate shapes.
The chopper is driven by a powerful, 6000RPM pneumatic motor and has a direct drive, variable bladed cutting cylinder operating in conjunction with
an adjustable, cam mounted polyurethane roller.
The chopped glass is ejected by an integral airmover into the centre of the slurry spray cone producing the perfect spray pattern for which the PIIA is justly famed throughout the GRC industry.
As the PIIA Concentric has a 2mm annular ring slurry nozzle it requires an appropriately sieved slurry but it is fitted with a water flush which facilitates cleaning and maintenance.
The PIIA is supplied as standard with a 6000 R.P.M. airmotor, 6 slot cutting cylinder and 3 hole rovings tube but the following variations are available:
2600 RPM airmotor - output 0.2-0.5Kg/min.
6 slot cylinder ……. 18mm & 36mm strands
8 slot cylinder ……. 14mm strands
9 slot cylinder ……. 12mm strands
