In short
Gentle surface cleaning by low-pressure rotary vortex: air, water and granulate in a special nozzle at 0.5–4 bar – only the surface is treated.
The JOS method enables gentle cleaning of delicate surfaces by low-pressure rotary vortex blasting. Air, water and fine granulate are set in rotation in a special nozzle at 0.5–4 bar; only the surface is treated, the material layer beneath remains undamaged.
