Hi Neville, great question. Dunlite & Gentech are both built / distributed by an Australian company called Welling & Crossley. They have been Australian owned and operated since 1926, and are recognised as an Australian leader in the manufacture and supply of petrol & diesel power equipment and generating sets for industrial, commercial and domestic applications.
Welling & Crossley's range of portable generators has always been Gentech. Then around 20 years ago, they acquired a similar portable generator brand in Dunlite. Each brand has excellent recognition throughout Australia. So both brands now come out of the same Welling & Crossley factory and so the models are not just similar, but the same – either branded ‘Gentech’ or ‘Dunlite’.
In the instance where the price is slightly different, this just relates to stock levels and availability of that particular model. In any case, there are Dunlite/Gentech portable petrol generators from around 2kVA to 16kVA in size, mostly powered by genuine Honda engines and are the trusted option for tradesmen, farmers, industrial applications, domestic requirements, small businesses and much more... similarly, the Dunlite/Gentech diesel portable generator models up to around 9kVA in size are powered by the likes of Lister Petter and Kohler engines and used for all matter of commercial, industrial and rural power requirements.
All Gentech/Dunlite products are backed by comprehensive warranties from the manufacturer (Welling & Crossley) and come with national service agent and spare parts support. Thanks.
