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.

    Great moisturizer
    Size: 8 Ounce (Pack of 1)
    This is the most pleasant and effective moisturizer I’ve tried. It’s very smooth and creamy, and it soaks in quickly. Ends dry, itchy skin on my legs damaged by daily golfing in shorts.

    I love this product
    Size: 8 Ounce (Pack of 1)
    Since I started using this Dove Pro-Retinol + Firming cream, I honestly noticed a difference in my skin. I love that it’s not heavy or greasy—it absorbs quickly and leaves my skin feeling super soft from the very first application. I like to apply it every night and it leaves my skin well hydrated all night it doesn't matter the rose is very effective it also works for your skin marks like pink scars with contamcy you notice the difference in your skin

    Great product!
    Size: 8 Ounce (Pack of 1)
    This is a great product. I can definitely feel my skin getting more plump and hydrated. There is no scent, which I like. I was pleasantly surprised at the size of the bottle. It was much bigger than I expected. I will definitely be purchasing again.

    Feels like a luxury product
    Size: 8 Ounce (Pack of 1)
    the consistency and lasting hydration of this product is fantastic! I use it year-round because it is very moisturizing, but it is especially great in the summer when I don't want something heavy or greasy on my skin. The scent is a little perfumey, but it is subtle and I actually think it is very pleasant and not overpowering
