The Downland MKII Spraygun/chopper is the original industry 'workhorse' and has been in continuous production for over 20 years. It is a robust spraygun of simple, construction, capable of spraying course slurry and best suited to open and flat moulds.
The chopper is driven by a powerful, 6000 RPM pneumatic motor and has a direct drive variable bladed cutting cylinder operating in conjunction with an adjustable, cam mounted polyurethane roller. Chopped glass is expelled from the cutting chamber by a lightweight airmover which impinges on the slurry stream.
The MKII Twinhead has the chopper mounted above the spraygun but it can also be swung through 90° to produce a side-by-side arrangement which some operators find preferable.
The MKII is supplied as standard with a 6000 RPM motor, 9mm spray nozzle, 6 slot cutting cylinder and 3 hole roving tube, but the following variations are available:
6000 RPM airmotor - Output 0.5-2Kg/min 2600 RPM airmotor - Output 0.2-0.5Kg/min.
