Silence the hum of your grow room without sacrificing airflow. AC Infinity Duct Silencers transform noisy ventilation systems into whisper-quiet climate control solutions, cutting fan and airflow noise by up to 50%. Available in sizes ranging from compact 4-inch models for small tents to powerful 8-inch configurations for commercial setups, these silencers use precision-engineered egg-crate neoprene foam to absorb sound waves before they escape your grow space. Whether you're managing a high-CFM inline fan or building a complete stealth ventilation system, AC Infinity Silencers deliver the peace and quiet you need to grow with confidence.
AC Infinity has earned its reputation by solving the biggest challenge indoor growers face: maintaining powerful ventilation while keeping noise levels down. These duct silencers integrate seamlessly into any setup, providing professional-grade sound dampening without restricting airflow.
Ventilation noise doesn't just disturb you—it can alert neighbors and compromise your grow's discretion. AC Infinity Silencers tackle this head-on:
Matching your silencer to your ventilation system ensures optimal noise reduction and airflow efficiency:
Maximize noise reduction by combining your silencer with complementary AC Infinity components:
How much quieter will my grow room be with a duct silencer?
AC Infinity Duct Silencers reduce fan and airflow noise by up to 50%. You'll notice a significant difference—what once sounded like a constant hum becomes barely noticeable background noise. The actual reduction depends on your fan speed and tent size, but most growers report their ventilation becomes quiet enough to run 24/7 without disturbing sleep or daily activities.
Will a silencer reduce my fan's airflow or CFM?
No. AC Infinity Silencers are designed with smooth internal airflow pathways that maintain full CFM performance. The egg-crate foam absorbs sound without creating resistance, so your inline fan continues to move air efficiently while operating much more quietly.
Can I install the silencer on the intake side or only the exhaust?
You can install it on either side. Most growers place the silencer on the exhaust side after their inline fan for maximum noise reduction, but it works equally well on the intake side. For the quietest setup, consider using two silencers—one on each end of your ventilation system.
What size silencer do I need for my fan?
Match the silencer diameter to your fan and ducting size. If you're running a 6-inch inline fan with 6-inch ducting, use a 6-inch silencer. AC Infinity offers 4-inch, 6-inch, and 8-inch models to fit standard grow tent ventilation setups.
Do silencers work with non-AC Infinity fans?
Absolutely. These silencers are universally compatible with any brand of inline fan or ducting system. As long as the diameter matches, you'll get the same noise reduction benefits regardless of your fan manufacturer.
How long do duct silencers last?
With proper installation, AC Infinity Silencers last for years. The steel body resists rust and damage from humidity, while the neoprene foam retains its sound-dampening properties indefinitely. There are no filters to replace or moving parts to maintain.
Can I use a silencer with a carbon filter in the same system?
Yes, and we recommend it. A typical quiet setup includes a carbon filter for odor control, followed by your inline fan, then the duct silencer for sound dampening. This combination gives you complete environmental control—eliminating both smell and noise from your grow space.
Where should I position the silencer in my ventilation line?
Install it immediately after your inline fan on the exhaust side. This placement captures noise at the source before it travels through your ducting. Make sure connections are secure with duct clamps to prevent air leaks and vibration noise.
