Description
  • 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

  • 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.

    Easy assembly
    Color: Silver
    Super easy assembly, one screw in tree trunk is unscrewed to place bowl and tree together - Phillips screwdriver needed. I bought the silver ring holder which perfectly suits my personality and decorative style. Can't tell you how wonderful it feels to finally have all of my rings off of my desk and stored in an easy to find place! Space saving is high on my list because I currently live in a 28' camper, so do not have my larger jewelry boxes in here with me. It only arrived today (7/28/2019) so this is with only a single days use, but am very pleased with the purchase and value for the ring holder - I was specifically looking for an inexpensive metal ring tree versus a plastic one.
