The nebulizer is the core of the Polysher™, it creates the fine mist of alcohol which evenly smooth the PolySmooth™ model.
The nebulizer membrane may develop micro-cracks over time which may affect the mist production performance. We recommend changing the nebulizer when you notice a drop in your mist density or height. The nebulize can usually last ~100hours of polishing time. The Polysher™ comes with 2 nebulizers.
