Product Features & Fitment

This single-speed fan is not speed-controllable and is optimized for spot cooling where space is limited. The ball-bearing design allows for mounting in any position, unlike sleeve-bearing fans which require horizontal airflow orientation. Electrical connection is provided via wire leads. The cast-aluminum housing ensures durability and efficient heat dissipation. Note that operating at 50 Hz will reduce airflow by approximately 20%.
