DYNAJET
350th HELI
The DYNAJET 350th HELI is a trailer-mounted hot- and cold-water high-pressure water jetting system delivering up to 350 bar. Built on a proven platform that has been continuously refined over more than two decades, it combines reliable performance, independent operation and the durability required for demanding professional work.
Working pressure should match the task. Surface preparation and general maintenance typically use 150 to 500 bar, while industrial coating removal and concrete work require higher pressure. Contact your nearest distribution partner for guidance on the right pressure and flow rate for your specific job.

Hot and cold water high-pressure cleaning for professionals
The DYNAJET 350th HELI is designed for professionals who need a dependable hot- and cold-water high-pressure water jetting system for demanding day-to-day operation. Delivering up to 350 bar with hot or cold water, it is well suited to industrial maintenance, construction, municipalities, agriculture and many other applications where reliability is as important as cleaning performance.
Built on a robust trailer platform with an integrated 300-litre water tank, the 350th HELI enables independent operation without relying on a permanent water supply. Its compact dimensions, stable towing characteristics and practical layout make it easy to transport between sites and quick to put into operation.
At the heart of the machine is DYNAJET's HELI valve technology, providing stable pressure characteristics while reducing pressure in the high-pressure hose and spray gun when the trigger is released. Combined with the proven Kubota diesel engine, efficient hot-water system and durable industrial components, the result is a machine developed for long service life and dependable operation under demanding working conditions.
For more than two decades, the DYNAJET 350th platform has earned its reputation among professional operators through its robust construction, straightforward operation and reliable performance. Continuous refinement has kept the machine up to date while preserving the proven design that has made it one of DYNAJET's most trusted trailer-mounted units.
Also available as a stationary skid unit as the DYNAJET 350sh HELI.
FULLY INDEPENDENT OPERATION
The diesel engine combined with a large integrated water tank allows the 350th HELI to operate independently of external power and water supply. This supports flexible, uninterrupted cleaning work in demanding and remote locations.
EFFICIENT HOT‑WATER BURNER
The integrated diesel burner heats the water efficiently for hot‑water cleaning applications. Designed for stable temperature control and reliable operation, it supports effective cleaning where heat is essential for results.
MATCH Handle and Fuel/Water Gauge included for 350th HELI
Now included with every order for a new 350th HELI for the rest of 2026.
The MATCH Handle lowers engine speed automatically when you release the trigger gun, cutting diesel consumption and reducing wear. The two Fuel/Water Gauges let you check diesel and water levels at a glance, without opening the tank.
