Featuring a corrosion-resistant galvanized steel body, dual aluminum flanges, and high-grade neoprene egg crate foam, it reduces fan noise by up to 50% without compromising airflow. Lightweight and durable, it fits 4-inch duct openings and is ideal for creating quieter, more comfortable environments in both professional and home settings. ## Description Product Description A ventilation ducting tool designed to dampen or reduce noise coming from airflow in grow tent or server closet ventilation systems. It utilizes high-grade neoprene foam crafted in a wave crest pattern that diminishes sound wave movement, reducing noise pollution by up to 50%. The egg crate foam muffles sound vibration while allowing maximum airflow passthrough for both intake and exhaust configurations. Both aluminum flange openings also assist in absorbing sound waves from vibrations, seamlessly fitting over your inline duct fan’s flange. Each silencer is built with a solid galvanized steel body that is corrosion-resistant and can withstand extreme temperature changes. Applications The duct silencer is often paired with inline extractor fans in grow tents and hydroponic grow room applications. It can be installed anywhere in the ventilation system chain like in between the fan and ducting. The silencer can also be used in many home HVAC applications including AV equipment room cooling, closet cooling, and bathroom ventilation. This creates a comforting home environment that is quieter and more relaxing, or a workplace that is less distracting. Duct Silencer An inline duct silencer designed to reduce noise from active exhaust fans. Eliminates noise level by up to 50% by absorbing acoustic vibrations caused by air movement. Superior Noise Suppression for a Quieter Space Whether you are ventilating a grow tent or a server room, inline fans produce a sound that may draw unwanted attention as well as disturb your housemates, family, or even your neighbors. By using this silencer, you create a quieter and more relaxing environment by diminishing the noise output of your fan or rushing air. Vibration Reduction This silencer features aluminum flanges on both ends that fit your existing fan or ducting to help diminish sound waves coming from fan vibrations. Sound Absorption As sound travels through the chamber's foam, it's dampened by the wave crest form, cutting noise output from rushing air or the fan by up to 50%. Complete Passthrough With no obstructions in the silencer chamber and an egg crate pattern foam, air can be taken in or exhausted with no impact on CFM. Sturdy and Durable Body A strong, long-lasting body made of galvanized steel that is lightweight, resistant to corrosion and can take on extreme cold or heat.

I ultimately returned the one before the fan because the improvement was relatively minor. **Q: Can you connect these mufflers in series? And what impact does that have? e.g. one reduces 50% two reduces 75% ... and so forth?** A: I don’t think they can be used end to end but you can put one on either side of the fan and that should reduce the sound.... or if you’d like you can put one directly against the fan and then add another one at the end of a duct as well. I can’t give you any specific numbers though. **Q: Can I simple insert this silencer (not fan) before my output in my home music studio?** A: The openings on each side is 4" in diameter. I'm not sure exactly what your affixing this to but if it's similar to any duct opening you'll need a clamp or coupler. Hope this helps! **Q: Will this work on a radon fan system?** A: i dont know about a radon but ive used a hyperfan and it fits perfect. ive also used one of those cheap vivosun ones with the red fan blades and it is about a quarter inch smaller than the flange on th muffler. it does work well though. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent *by M***S on 20 May 2026* Top carbon filter ### ⭐⭐⭐⭐⭐ Works *by R***S on 22 October 2025* Definitely makes it a bit quieter ### ⭐⭐⭐⭐⭐ five stars *by M***? on 20 June 2026* Like most AC Infinity products this silencer is another winner, it works perfectly well at reducing noise, in fact beyond expectations!
