FAQs

What is the main benefit of using this noise reduction clamp?+

Its primary benefit is to significantly reduce noise and vibrations from your ventilation fan by isolating it from the ductwork. The durable rubber absorbs sound waves, creating a much quieter grow environment.

Will this clamp fit my 6-inch inline fan and ducting?+

Yes, this clamp is specifically designed to create a secure, airtight connection for any standard 6-inch ducting, fans, or filters. For other sizes, we also offer 4-inch and 8-inch versions.

Is the installation difficult?+

Not at all. Installation is simple and requires no special tools. Just slip the flexible rubber coupler over the duct ports and tighten the stainless steel clamps with a Phillips or flathead screwdriver for a secure fit.

How does this compare to a standard duct clamp?+

A standard clamp only secures the ducting. This AC Infinity clamp acts as both a coupler and a noise dampener. Its nitrile rubber body isolates vibrations that would otherwise travel through your ductwork and amplify.

Can I use this clamp in a high-humidity environment like a grow tent?+

Absolutely. The clamp features stainless steel bands and a high-grade nitrile rubber coupler, both of which are resistant to rust and degradation from moisture, making it ideal for humid grow tents and HVAC applications. Check out our guide to AC Infinity grow tents and air filter kits to learn more about creating the perfect environment.

What other products can help make my ventilation system quieter?+

For maximum noise reduction, consider pairing this clamp with an AC Infinity Duct Silencer. This combination will significantly reduce noise from both fan vibration and airflow turbulence.
