Small, efficient and independent: that's DYNAJET's compact "md" class with a powerful and low-consumption diesel motor. Just like the other DYNAJET trollies in the "md" class, the special features of the DYNAJET 350md, offering a working pressure of up to 350 bar (5,075 PSI), are its extreme manoeuvrability, small dimensions and easy-loading and easy-transportation characteristics.



  • Robust, powder-coated steel frame for optimum machine protection and a long service life
  • Single-axle chassis with pneumatic tyres for easy on-site manoeuvrability
  • A perfect centre of gravity for flexibility and stability
  • Screws made of corrosion-free material for high durability
  • Central lifting eye for easy transportation and handling
  • Operating-hours counter for optimum product costing analyses
  • 12 V socket for the power supply to the Dynabox 12 V hot-water module


  • Vibration-proof starter battery for effortless start-up
  • Flexible vibration elements to absorb vibration between the motor, pump and frame
  • Cover with sound insulation for sustainable reduction of noise emissions
  • Electric starter for easy starting of the machine
  • Robust air-cooled 2-cylinder diesel motor
  • Belt drive for quiet operation and extended maintenance intervals
  • Automatic speed reduction when the pistol is not in use, to minimise noise emissions, wear, and fuel consumption
  • Oil-pressure monitoring to protect against motor damage

Water supply:

  • Suction pressure control to protect the pump in the case of a weak water supply
  • Cleanable stainless-steel water filter for maximum service life of the pump
  • Low-maintenance industrial crankshaft pump for high performance and maximum service life
  • Thermo safety valve for additional protection of the pump
  • Safety valve for additional safety during operation
  • Manual pressure adjustment for easy operation
