Who This Is For

  • You are installing a duct silencer because the constant fan vibration in your setup makes the room feel loud.
  • You are upgrading your ventilation path because the rush of air through your 6 inch ducting is too loud to ignore.

What We Found

  • Those reversible flanges are great because they let you mate the silencer directly to the fan without extra ducting.
  • The egg-crate foam inside does a better job at breaking up air turbulence than the flat liners we see on cheap units.

What Users Say

  • Owners who added this to their 6 inch inline fans say the sound dropped enough to have a normal conversation nearby.
  • Users who mounted this directly to the fan intake say it killed the motor whine that used to echo through the ducting.

AC Infinity 6" Duct Silencer

Tired of the constant hum from your high-powered ventilation system? The AC Infinity 6" Duct Silencer is engineered to dramatically reduce fan noise, creating a quieter and more comfortable environment for your indoor garden or HVAC setup. It seamlessly integrates with your existing equipment, like an AC Infinity CLOUDLINE fan, to cut noise levels by up to 50%. At its core, the silencer uses high-quality neoprene foam with a convoluted egg-crate pattern to absorb sound waves and vibrations effectively. The entire unit is housed in a rugged, galvanized steel body that resists corrosion and withstands extreme temperatures, ensuring long-lasting, silent performance.

FAQs

How much noise does the AC Infinity Duct Silencer actually reduce?+

It is designed to reduce fan and airflow noise by up to 50%. The actual reduction can vary based on your fan's speed, the length of your ducting, and the ambient noise in your space, but it provides a very noticeable decrease in sound.

Is this silencer compatible with fans from other brands?+

Yes, the 6" Duct Silencer is compatible with any 6-inch inline fan or ducting. However, for guaranteed fit and optimal performance, we recommend pairing it with an AC Infinity CLOUDLINE fan.

Where should I install the silencer for the best results?+

For maximum noise reduction, install the silencer directly on the output side of your inline fan, before the ducting run. You can also install a second one on the intake side for even quieter operation. For an extra secure fit, consider using an AC Infinity Noise Reduction Clamp.

Does the silencer reduce airflow (CFM)?+

The silencer is designed with an aerodynamic profile to minimize any impact on airflow. While any object in the airstream can cause a minor reduction in CFM, the effect of this silencer is negligible and will not significantly impact the performance of your ventilation system.

What's the difference between the 4", 6", and 8" models?+

The only difference is the diameter of the duct opening. You should choose the model that matches your fan and ducting size. This is the 6" model, but we also offer the 4" Duct Silencer and the 8" Duct Silencer for different setups.

How does this fit into a complete ventilation system?+

A duct silencer is a key component for quiet operation. A typical setup includes an inline fan, ducting, and one of the many carbon filters to control odor. The silencer is placed after the fan to muffle the noise. To learn more about setting up a full system, check out our in-depth guide on AC Infinity kits.
