FAQs

How much noise reduction can I realistically expect?+

The silencer is designed to reduce fan and airflow noise by up to 50%, creating a significantly quieter operating environment for your grow space or home.

Is this compatible with non-AC Infinity fans?+

Yes, this duct silencer is compatible with any 8-inch inline fan or ducting, regardless of the brand. For a seamless, high-performance setup, we recommend pairing it with an AC Infinity Cloudline T8 fan.

Where in my ventilation line should I install the silencer?+

For best results, install the silencer directly on the exhaust side of your inline fan. You can also add a second unit to the intake side for even greater noise reduction in sensitive environments.

Does the silencer restrict airflow?+

The silencer is engineered with aerodynamic flanges and an open-cell foam structure to minimize any impact on airflow and static pressure, ensuring your fan performs efficiently.

How do I maintain the duct silencer?+
