Quiet ceiling fans

A ceiling fan should never be heard. The entire SEY Maison collection operates between 28 and 34 decibels, below the level of a whisper: factory-balanced copper and DC motors, profiled blades that move air without whipping it, and the kind of silence that lets you sleep with the windows closed, even in a heatwave.

For context: a wall-mounted air conditioner runs at 40-55 dB, a pedestal fan at 45-60 dB. At 30 dB, the sound disappears behind that of a calm room — it is measurable, and it is the first criterion of the whole collection.

Your questions, answered

What counts as a truly quiet ceiling fan?+

Below 35 dB a fan becomes inaudible in a living room; below 30 dB it stays inaudible at night in a bedroom. SEY Maison models operate between 28 and 34 dB depending on speed, thanks to balanced copper or DC motors and profiled blades.

Can you sleep with a ceiling fan on?+

Yes: at 28-30 dB the airflow is quieter than a whisper, and many customers use it as gentle white noise. Bedroom models include a night mode with progressive slow-down.

Is a DC motor quieter than an AC motor?+

At equal speed, yes: a DC motor vibrates less and draws 5-30 W versus 50-100 W for AC. It also allows very low night speeds.

How does it compare with air conditioning?+

A split air conditioner emits 40-55 dB indoors — conversation level. A 30 dB ceiling fan is perceived as two to four times quieter, with a felt cooling of 3-4 °C.
