Industrial Power

The powerful HYW4000DE is a heavy-duty diesel power washer from Hyundai. Producing an adjustable continuous working output pressure up to 250 bar / 3600psi and a maximum pressure of 4000psi with a 15L/hour flow rate. This high-pressure jet washer is perfect for cleaning professionals in industrial, agricultural, heavy plant and commercial environments. Fitted with a 12hp, 498cc Hyundai air-cooled OHV direct injection diesel engine driving an Annovi Reverberi (AR) Triplex Pump, with ceramic pistons, both mounted on to a strong metal frame via an anti-vibration rubber mounted subframe. The 4000psi pressure washer is ideal for heavy-duty environments. The diesel engine is fitted with an easy electric start but has a back-up recoil (pull-start), should you ever need it which ensures you can always get your job done.

Annovi Reverberi (AR)

Hyundai diesel jet washers use Annovi Reverberi (AR) high pressure pumps on their engine driven pressure washers to ensure maximum performance and longevity. Annovi Reverberi (AR) is one of the world leaders in pressure washer pump manufacture.

Heavy Duty

Weighing 135kg the HYW4000DE is built with a heavy-duty powder-coated tubular steel trolley design frame making it easier to manoeuvre. Fitted with four wide, large-diameter foam-filled puncture-proof tyres allowing it to be moved across rough and difficult terrain such as muddy fields and stone driveways. The large ergonomic handlebar makes handling easy and the built-in hose and lance gun holder will help keep everything organised when moving between jobs. The quick-release couplings on the pump, hose and trigger gun allow you to quickly get the job going and also to add additional hoses as required. Suitable for the most demanding cleaning tasks the HYW4000DE is the perfect industrial diesel pressure washer for the professional user.

Applications & Use

Ideal for cleaning farm machinery, heavy plant, commercial vehicles, skips, wheelie bins, terraces, porches, patios, swimming pools, driveways, patios, etc. The HYW4000DE is a cold water pressure washer that is used with mains water or gravity fed and will draw water uphill 1.5m where water can be taken from a water butt, no need for an outside tap.
