Why Buy From Us

Close

The Jetwave Executive Silent 280-31 is engineered for the toughest industrial environments, delivering ultra-quiet operation, uncompromising power, and exceptional longevity. Designed for serious operators who demand reliability, safety, and performance, this premium hot water pressure cleaner is built to excel in mine sites, shipyards, logistics facilities, councils, government operations, and heavy industry applications where noise, performance, and uptime all matter.

Powered by the advanced Kohler™ KDI1903 liquid-cooled 42HP diesel engine, the Executive Silent delivers consistent output, exceptional torque and incredible fuel efficiency under all loads and speeds. Pairing this engine with the JW® UDOR® premium Italian triplex plunger pump — running at an optimal 1550 RPM through a direct soft coupling — ensures minimal wear, longer pump life, and absolute reliability without reduction systems.

Ultra-Silent Industrial Cleaning Washer for Extreme Performance

Jetwave’s patented ultra-silent cabinet dramatically reduces operational noise to approximately 70 dB, enabling after-hours cleaning in residential or built-up areas without disruption. The fully enclosed steel cabinet also safeguards critical components from weather, physical impact, dust, and user error — giving operators confidence in the most extreme environments.

The vertical diesel-fired burner, paired with a 500-BAR-rated coil, delivers efficient, high-temperature cleaning power that cuts through grease, oils, and industrial contaminants with ease. Whether you’re blasting buildup from machinery, sanitising plant rooms, or maintaining large commercial equipment, the Executive Silent 280-31 delivers unstoppable performance.

Smart System Control & Machine Protection

The InteliUMS™ LCD Unit Management System provides real-time machine readouts, warnings, and auto-shutdown safety functions that protect all major components, including the burner, pump, and engine. This intelligent control system helps reduce service downtime and prolongs machine life — a must-have feature for operators in remote or demanding environments.

Additional essential safety features include a battery isolator, emergency stop, lockable fuel fill point, and premium hydraulic and thermal protection systems.

Powerful Industrial Output for Heavy-Duty Operators

The Jetwave Executive Silent 280-31 has been designed for industrial-grade, continuous-duty operation. With an output of 4060 PSI (280 BAR) and an impressive 31 L/PM flow rate, this machine is capable of removing the most stubborn grime, residue, and contaminants — even under harsh working conditions.

For operators needing maximum productivity, the optional Dual Operator Upgrade allows two users to run simultaneously at 3000 PSI / 20.5 L/PM each, making it ideal for large-scale facilities or fast-paced industrial cleaning teams.

Why Choose the Executive Silent Series?

If your business requires reliable, ultra-quiet, high-temperature industrial cleaning power, nothing compares to the Jetwave Executive Silent Series. It’s designed from the ground up for operators who demand maximum uptime, long-term performance, and fully protected machinery that thrives in the harshest working environments. 

Investing in a silent pressure washer adds another element of protection when on the job site. Being its own independent unit, this eliminates the need to run power cables across the floor creating potential trip hazards. 

The unit also comes in a full trailer configuration meaning you have a full setup ready to go without the need to run any water hoses or similar. The unit is mounted onto the back of a 12' x 5' dual axle Australian made trailer with hydraulic brakes and spare wheel along with other premium attachments including; 2 x Apache A-frame hose reels, a 1500 litre water tank, a 1500mm Alloy lockable toolbox and a 30m high pressure hose with a 30m low pressure inlet hose.
