Our smart controllers and integrated grow equipment are designed to work together to create the perfect climate for your plants. 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. 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. 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. 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. This silencer features aluminum flanges on both ends that fit your existing fan or ducting to help diminish sound waves coming from fan vibrations. 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%. 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. A strong, long-lasting body made of galvanized steel that is lightweight, resistant to corrosion and can take on extreme cold or heat. ## Features - A duct muffler designed for use with inline fans in grow tents, bathroom fans and other HVAC applications. - Features dual aluminum flanges to help absorb sound waves from fan vibrations and airflow. - High-quality neoprene foam in an egg crate pattern that will reduce fan noise by up to 50%. - Galvanized steel body that is corrosion-resistant and can withstand extreme temperatures. - Duct Opening Diameter: 4 inches | Length: 15 inches | Weight: 2.30 pounds ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0829GJ5Q7 | | Best Sellers Rank | #52,362 in Patio, Lawn & Garden (See Top 100 in Patio, Lawn & Garden) #58 in Greenhouse Ventilation Equipment | | Brand Name | AC Infinity | | Customer Reviews | 4.5 4.5 out of 5 stars (772) 4.5 out of 5 stars | | Global Trade Identification Number | 00819137021051 | | Item Weight | 2.3 pounds | | Manufacturer | AC Infinity | | Manufacturer Part Number | AC-DSA4 | | Model Number | AC-DSA4 | | Number Of Items | 1 | | Unit Count | 1 Count | | Upc | 819137021051 | ## Product Details - **Brand:** AC Infinity - **Global Trade Identification Number:** 00819137021051 - **Item Weight:** 2.3 Pounds - **Manufacturer:** AC Infinity - **UPC:** 819137021051 ## Images ![- AC Infinity Inline Duct Fan Silencer, 100mm Noise Reduction Muffler Blower | Silencer for Indoor Hydroponics Grow Tent Ventilation Systems - Image 1](https://m.media-amazon.com/images/I/51AYf5JWdAL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: does this get installed before the fane for after the Fan and how far?** A: I've installed one before and one after - directly on the fan. 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 ### ⭐⭐⭐⭐⭐ Perfect for venting a sound booth *by on Reviewed in the United States September 19, 2025* Purchased for a fairly novel use: ventilation for a Whisper Room isolation booth. I am a professional audiobook narrator and require a very low noise floor. Unfortunately, in the past, I've been relegated to quiet computer fans, which simply do not replace enough air in a small space that I spend hours in at a stretch.This fan has been a game changer. With the old computer fan system, I'd end the work day partially asphyxiated - literally. Overly tired, light-headed and confused. Not good! Changing to this fan, I'm probably replacing the air in the booth several times per hour, meaning everything about my performance has drastically improved. The best thing? I can't hear the fan *at all*, and neither can my audio equipment. My noise floor is -72dB with this fan on the fourth setting.Over all, I couldn't be happier. ### ⭐⭐⭐⭐⭐ Love this and it works as intended *by on Reviewed in the United States August 8, 2021* I have this added in a 2x4x5 tent. I originally was running a crappy vivosun 4" fan and filter because of Reddit and boy did my girls suffer. Everyone online says one cycle every 1-3 minutes. They're nuts, you want to cycle once a minute or more if you're doing air exchange for cooling. I have my AC at 70 and with the vivosun running full speed the tent was hitting 84-87. With this 6" setup and the controller 67 at 70% during day 30% at night the tent never gets over 72-74 during the day and 65-68 at night. What an amazing improvement overall.For the silencer, I am using it in front of the fan that is working as an exhaust and most people are probably going that's wrong but it's absolutely right for me. I had it configured in the other fashion and it sounded like a jet engine in the tent. In this setup it sounds like swooshing air and I love it. Best decision ever made now I have to dig my 8" out of the ceiling of my closet and attach a 8" silencer to it. ### ⭐⭐⭐⭐⭐ Reduced noise from HVAC fan and return vent *by on Reviewed in the United States January 15, 2026* Made a difference in the noise from our HVAC. The unit and a return is right behind our TV room and we could hear the fan running - I put this in the line between the HVAC unit and the return grate in the room and it made a noticeable difference to me. Installation was very easy if you know what you are doing. ## Frequently Bought Together - AC Infinity Inline Duct Fan Silencer, 4" Noise Reduction Muffler Blower Silencer for Indoor Hydroponics Grow Tent Ventilation Systems - AC Infinity Noise Reduction Clamp 4-Inch, Duct Coupler with Stainless Steel Clamps, Flexible Rubber Coupling for Inline Fans and Carbon Filters in Growing and HVAC - AC Infinity CLOUDLINE PRO T4, Quiet 4” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/177166705-ac-infinity-inline-duct-fan-silencer-100mm-noise-reduction-muffler](https://www.desertcart.tn/products/177166705-ac-infinity-inline-duct-fan-silencer-100mm-noise-reduction-muffler) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-25*
