AC Infinity Inline Duct Silencer – 4", 6" & 8"

Your fan isn't the loud part. The air is. Air leaving an inline fan is turbulent and fast, and ducting carries that rush all the way along the run and out of every gap. An AC Infinity Inline Duct Silencer sits straight after the fan and soaks up that noise in a sound-absorbing lining before it ever reaches the rest of your ducting. It's the single biggest upgrade for anyone running a fan in a bedroom, flat or anywhere people sleep.

Why add a silencer

• Absorbs airflow noise at source. The sound-absorbing inner lining tames the roar before it travels.
• Full-bore design keeps airflow loss to a minimum.
• Works with any brand. Standard 4", 6" and 8" ends fit RAM, AC Infinity, Rhino and other fans and ducting.
• Clamps on like ducting. No tools or special fittings needed.

The quiet stack

For near-silent extraction, combine all three: a noise reduction clamp to stop vibration, this silencer straight after the fan, and acoustic ducting (like RAM Sonoduct) for the run.

Rose's Pro-Tip

"Put the silencer right on the fan's outlet, not halfway down the run. That's where the noise is born, and catching it there means the rest of your ducting stays quiet too."

FAQ

Will it reduce my airflow?
Very slightly, like adding a short length of ducting. The bore is full size.

Intake or exhaust?
Either, but it does most good on the exhaust side straight after the fan.
