Description
Overview:
This genuine Makita fan (OEM No. 240139-9) is a replacement cooling impeller for selected Makita angle grinders, including GA4034 and GA5034. Moulded from durable engineering plastic, it sits on the motor shaft to draw air through the grinder housing, helping to regulate internal temperature during use. Reliable cooling protects the motor and other internal components from heat build-up, supporting consistent performance and longer service life. It is engineered to the correct dimensions for a secure fit and balanced airflow on compatible models, restoring factory-standard cooling when the original fan is worn, damaged, or missing. Suitable for professional trades and home users alike, this part helps keep your angle grinder running efficiently on metalwork, masonry, and general fabrication tasks.
Key Features:
- Genuine Makita part for precise fit and performance (OEM No. 240139-9)
- Robust moulded plastic construction for durability and stability
- Restores correct airflow to help prevent overheating under load
- Helps protect motor windings and bearings by improving heat dissipation
- Balanced design to minimise vibration and maintain smooth running
- Compatible with specified Makita GA40/GA45/GA50 series grinders
- Suitable for routine servicing or repair after fan wear or damage
- Straightforward replacement for competent users following the service manual
Typical Applications:
Ideal for maintaining the cooling system of Makita angle grinders used in metal cutting, grinding, weld preparation, surface cleaning, and light masonry work. Useful in workshops, site environments, fabrication bays, and home garages where sustained or intermittent grinder use generates heat. Replacing a worn fan helps maintain consistent performance and reduces the risk of thermal shut‐down.
