Hollow jet belongs to the family of smart nozzles; it shoots a crystal clear stream of water, looking perfectly solid to the eye, yet being hollow inside. This jet creates water columns twice as thick as a solid-stream nozzle using the same water capacity, making it the most efficient clear-water nozzle. The water effect varies on different spray heights – when at lower heights it creates a bell shaped water effect and at medium to higher spray heights the water pattern resembles the solid, lively effect created by smooth bore nozzles.
Hollow jets make an excellent choice for great spray heights – above 15 meters as the water capacity required is significantly less compared to the visual results. The inside – made of stainless steel – flow directors create a highly visible and stable water stream. MJ 300 can shoot water up to more than 25 meters and it is also available as a complete kit – floating or fixed.
Made of stainless steel AISI 304 (or 316 on request) for expanded life cycle, better appearance and even greater efficiency.

- Clear Water Effect
- Hollow Stream for Greater Energy & Water Efficiency
- Significantly Less Water Capacity Required than Solid-Stream Jets
- Heavy Duty Machined Construction
- Made of Stainless Steel AISI 304
- Not Water Level Dependent
- Water supply to the jet must be linear, non-turbulent
- Highly efficient nozzle due to the Stainless Steel frictionless inside surface
MJ 125 Hollow Jet creates a 36mm thick water column using the same amount of water as a 17mm-orifice Smooth Bore. The only difference is that Hollow Jet’s stream is hollow inside.
Pure Stainless Steel Construction
Hollow Jets are entirely made of AISI 304 Stainless Steel or 316 on request. This makes them practically invulnerable to corrosion, tarnishing, impacts and any kind of deterioration. Plus, the frictionless surface offers even greater efficiency.
