200 Bar. 14.7 Litres a Minute. The Top of Our Lineup.

The Dera DK780 is a 2800W induction-class pressure washer built for detailing bays and serious home setups — high flow, variable pressure, and four quick-change nozzles.

Pressure gets the headlines. Flow rate does the work. A machine that hits high bar figures but trickles water takes twice as long to rinse a panel and starves a foam cannon into producing thin, watery lather. The DK780 delivers roughly 14.7 litres per minute at up to 200 bar, which is what lets you sheet a full car down quickly, drive dense foam properly, and blast wheel arches and undercarriage without waiting. Variable pressure means you control that force rather than accepting it — dial it down for pre-rinsing over a coated bonnet, wind it up for concrete, engine bays and neglected wheels. Four colour-coded quick-change nozzles cover 0°, 15°, 25° and 40°, so switching between a pinpoint jet and a wide fan is a twist, not a toolbox job.

Maintenance — Reference Points

These service intervals are reference points for typical use; heavy commercial duty cycles may warrant more frequent changes. Use the oil grade specified in the manufacturer's manual, disconnect power and release pressure before any maintenance, and refer to the manual for current guidance. Keep the 0° nozzle away from paint, trim, seals and skin — at 200 bar it will cause damage and injury.
