A Fan is an Object commonly found in the Grineer Asteroid, Grineer Galleon and the Grineer Shipyard tilesets. It is non-operational, with blades bent out of shape and sparks flying out of its motor. Attacking it destroys the fan and allows passage to another area via an air duct.
- All fans in a given map are automatically destroyed at the start of a Survival mission.
- Fans can be scanned only in certain missions.
