VEVOR Walnuss Strahlgerät 30 L, Sandstrahlgerät 1600 W, Sandstrahlanlage zur Entkohlung von Ansaugkrümmern & Ventilen, Sandstrahler inkl. 2,5 kg Walnussschalen & 23 Adapter

We recommend 12–16 mesh walnut sand (approx. 1.0–1.7 mm diameter) for this 30L pull-rod sandblaster, as it provides high carbon removal efficiency, won't clog valve gaps or over-grind the valves/seats, and perfectly matches the air pressure of your machine.
