Genuine Bosch 1600591024 — Air‑Deflector Ring: a direct‑fit replacement ring that installs behind the grinding‑wheel guard to redirect cooling air and help keep dust, sparks and debris away from the gear housing, bearings and brush area.

Designed for Bosch blue‑series angle grinders, this part is listed for models such as GWS 6‑100 and GWS 6‑115 and is also shown on parts lists for 850W grinders (GWS 850 C / GWS 850 CE and similar GWS 850 variants).

Small, low‑cost and a direct drop‑in replacement (often shown as item #29/30 on Bosch exploded diagrams), the 1600591024 restores the tool’s intended airflow path and helps extend service life when the original ring is cracked, deformed or missing. This is a genuine Bosch spare you’ll commonly find in power tool parts listings.
