The benefits of diesel on your work site, farm or in the back of your truck are obvious; lower cost of operation and lower cost of ownership throughout the generator's life. Coupled with this, is the unit's 27 litre fuel tank providing a massive 10+ hours run time at 80% load.

Easy electric start comes as standard, and additional options include Earth Leakage Protection, Lifting Bar Kit and Remote Start Kit.

Product Q&A

Ask Us a Question
  • Hi, there are two generators listed, one is a Gentech, one is a Dunlite - They look similar, but slightly different pricing. What is the difference in the generators? Regards, Neville

    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. 

  • Can I use this generator to charge my power tool batteries?

    Hi there,

    Charging battery packs is fine from a conventional generator, we'd recommend having a steady load on the generator and don't connect appliances that will cause the load to jump around during charging.
