A recorded machine, not white noise
The source is “Ventilation #5” by Joseph SARDIN, recorded outdoors and categorized as a fan. AmbientBlend prepares a 20-second mono excerpt from that recording.
A real machine can include tonal hum and small changes in airflow. Compare it with the generated noise examples if you prefer a different balance of low and high frequencies.
Preview before making it a bedtime background
Press Play at a comfortable level and notice whether the mechanical character is what you want. Use the timer for an automatic end. If the hum becomes too recognizable, compare Brown or Pink noise.
An audio recording produces sound only. It does not move air, cool the room or replace the ventilation you need. Choose it for its audio texture.
A fan with another layer
Open the mixer if you want rain alongside the fan. Begin with the fan alone, add Rain, then lower whichever sound should sit behind the other. More layers are optional.
The short recording repeats and background playback depends on the browser. Test your own device before relying on a locked-screen session.

Start at a comfortable level. The volume percentages describe player settings; they do not measure the sound level at your ears. Playback with a locked screen or a background tab depends on your device and browser. Opening another page stops playback.
Common questions
Is this a real box fan recording?
It is a real large ventilation fan recording, not a box fan. The credited source identifies the machine as “Ventilation #5”. We keep that distinction visible.
Is fan noise the same as white noise?
No. This fan is a machine recording that can contain hum and repeating mechanical detail. White noise is a generated spectrum; the comparison guide shows our generated examples.
Can I keep fan noise playing all night?
You can leave the player running or choose a timer. The sound repeats a 20-second prepared file, and uninterrupted locked-screen playback depends on your device and browser.
