The Crookwell water treatment plant has upgraded 4 of their existing units. Amiga Engineering Pty Ltd acquired Genat and Wood in 2008, and has since upgraded the quality of the Aerator gearbox units. Parts/protection, that were originally added as an extra are now a 'standard' as all units require these separate parts for safety precautions and quality of the units. For slow turning output speeds, we highly recommend upgrading your Aerator gearbox to a high volume pump to ensure all internals are lubricated, and to stop any 'cut-out's' of your unit.
