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.

    Tasty, Easy to Take
    This is the 3rd flavor of this brand that I've tried. I have to say that I preferred the grape and the little strawberry hearts better than these, as far as taste. These also are quite high in Biotin at 33,333% of the daily value, if you take the 3 gummies that equal 10g fiber. If you do want 10g of fiber the jar won't last an entire month. I don't really need the hair/nail support, so I'll probably go back to one of the other flavors. These are so easy to get out of the wide-mouth jar and they don't stick together too much. They're a soft gummy and are easy to chew. I don't tend to have an issue with them sticking to my teeth. The jar I received was manufactured in Apr 2026 and expires Apr 2028. Another reviewer mentioned that they're made in the USA, but I don't see that claim anywhere in the listing or on the product...although they're distributed by a New York company.

    Fewer doses per jar, but good flavor
    I've been using migcopat fiber gummies for a while now, and I'm a fan of the brand, so I thought I would give these a shot. I appreciate the addition of the biotin and keratin. This just only has one flavor instead of three, which is blueberry, but it's quite pleasant, not overly sweet. These gummies are a little softer than the other migcopat gummies, but again nothing wrong with that. I am knocking one star from the review because this jerk contains 20 doses when you take three per day as opposed to the other maker gummies that I have where there's a 30-day supply with taking three per day. For me, the addition of the biotin and keratin doesn't justify losing a third of my supplement.

    Great value
    This is 1 of those items that would take months to give a fair assessment. It takes time for things like this to get into your system. This was a vine item and I wanted to try them as fiber is very important after 50. But I can not speak to the effectiveness. I hope and expect there would be no side effects. Texture seems normal for something like this. Not sure if theres a odor. But seems a good value. Not sure about taste either.

    A decent tasting Metamucil that does the job efficiently
    Size: 1.86 Pound (Pack of 1)
    The Metamucil powder inside does the job very well. I only need to take once a week in to maintain a consistency of bowel movement throughout the week. The flavor is decent as well. It doesn’t overdo so that I feel a good balance.

    Easy way to add collagen to your daily fiber
    Size: 1.86 Pound (Pack of 1)
    I find taking a lot of supplements boring. I do take Metamucil daily. Even though I eat a lot of salad and fruit, I find this is a helpful habit. The flavor is a bit different but not objectionable.
