Blade / Sweep Size 16 inches — that’s about 40-41 cm across. Provides a good balance between compact size and decent airflow.
Mounting / Design Wall-mounted; fixed bracket or plate to attach to wall. Might have vertical tilt adjustment to direct airflow up/down.
Speed Settings Usually 3 speeds (Low / Medium / High) so you can adjust airflow.
Oscillation / Air Direction May have oscillation (left-right sweep) or at least tilt adjustment vertically. Some models might have wide angle oscillation.
Motor A motor strong enough for consistent airflow; possibly copper winding or a strong motor rated for continuous use.
Noise Level Probably relatively low / “quiet motor” for home use. But exact dB
