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%.

  • 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.

    Adorable, Durable, and Dog-Approved!
    Size: Medium, Style: Sour Pooch, Size: Medium, Style: Sour Pooch
    My dog loves the Sour Pooch dog toy—so much that it’s quickly become one of his favorites! What really surprised me is how durable it is. He’s usually quick to tear toys apart, but this one has held up incredibly well, making it one of the few survivors in his toy box. The toy is super cute, lightweight, and just an all-around fun addition to his collection. It’s been a joy watching him carry it around and play with it daily. I’d definitely purchase again and highly recommend it to other dog lovers looking for a toy that can handle a bit of rough love.

    Squeaky and colorful
    Size: Small, Style: Skit-Tails
    Cute toy. Lots of squeaks. Probably best for a mid sized dog mouth— a chihuahua or Pomeranian might find it a little thick to manage.

    “Candy” dog toy
    Size: Small, Style: Mutts & Mongrels
    Great toy! I like the toy because it’s durable & it has no appendages to for the dogs to chew off. It will be destroyed at some point but I won’t have to start picking up stuffing for a long time.
