  • A duct fan designed to boost airflow in HVAC systems and ventilate home spaces like attics and workshops.

  • Features a variable fan speed controller, enabling you to optimize airflow and noise level for any application.

  • Unibody die-cast construction with no welded seams; reduces vibration while ensuring smoother airflow.

  • AC brushless motor with steel blades and lubricated bearings; not suitable in restricted airflow applications.

  • Duct size: 4" | Dimensions: 7.28 x 3.95 x 3.95 in. | Airflow: 106 CFM | Noise: 28 dBA | Bearings: Dual Ball

  • Product Description: An inline fan for duct boosting designed to improve airflow in heating and air conditioning applications, and ventilate home rooms like attics, workshops, bathrooms, and kitchens. Each fan uses an easy-to-use knob controller that adjusts fan speed for your specific airflow boosting needs. It features a unibody framework that helps reduce vibration and ensures smooth and low-resistant airflow. The matte black steel cylinder is fluted and ridged for easy and secure installation in-between ducting. Its balanced steel blades have a 67,000-hour lifespan and spin using permanently lubricated dual-ball bearings to eliminate regular maintenance. The dual ball bearings also allow this fan system to be mounted horizontally or vertically. This kit includes one AC powered inline booster duct fan, a speed controller with a power plug, mounting screws, and a cable management set.

  • Speed Controller: The inline variable speed controller can control the fan's speed and turn it on or off. Turning the knob will increase or decrease the fan speed and optimize airflow and noise levels for your application. Its speed range includes a low, medium and high threshold, producing up to 106 CFM and 28 dBA in noise. This speed controller uses a female aviation plug with a metal retainer, tightly securing its connection to the booster duct fan.

  • Applications: This versatile inline booster fan is made to be installed in between ducting for various applications that need improved air delivery. In households, it boosts airflow from HVAC units to remove stale air and odor, ventilating attics, workshops, kitchens, basements etc. In grow tents, grow rooms, and indoor gardens, it's primarily used as an intake fan to bring in fresh air. Please note this booster fan cannot be used standalone in high static pressure applications like room ventilation. Additionally, it is not suitable for use in applications with restricted airflow like systems that use carbon filters. For higher performance, see the CLOUDLINE Series.

    Love the sheets but GOSH THEY STINK
    Color: 19 - Forest Green, Size: Queen (20" X 30")
    I have the dark green sheets and bought these for extra cases to match. I would give them 5 stars if it weren’t for the fact that they smell absolutely horrible. I am so surprised after reading reviews that more people don’t mention it?! Maybe it’s more prominent in darker colors but I have washed these now 3 different times even with scent beads and still hate the smell. I wish I could accurately describe what it smells like— it’s just not good and for some reason, body heat only exacerbates it and makes the smell even worse and I wake up feeling like a smell like the sheets… which isn’t a good thing. Besides that, I do really enjoy them. They feel great on your skin and I love the color. I wish the smell didn’t kill them so badly for me ☹️

    Comfy soft pillow covers
    Color: 02 - White, Size: Queen (20" X 30"), Color: 02 - White, Size: Queen (20" X 30")
    Absolutely love these pillow cases! I bought 2 sets. After I received them & washed & dried them they did remain wrinkly. I just went ahead and put them on my pillows & the wrinkles went away. I continue to love the feel, coolness & comfort. Will definitely buy more.

    Sleek shear soft cool zippered pillow cases
    Color: 07 - Green, Size: Queen (20" X 30")
    I'm a huge fan of bamboo fabric. It feels great to wear and so it also feels good to sleep on, especially during hot and or humid spells. Pillowcases came in a pack of 2 and were well packaged and arrived undamaged. Shipping was very fast. Cases appear to be well made. they are a lovely soft green which is perfect for a restful bedroom setup. As expected the fabric is soft and relaxing against the skin, it seems to retain a cooler feel than cotton.Bamboo tends to be a thinner fabric that is light and once damp, dries pretty quickly. Perfect for folks who run hot normally and need extra cooling during the summer or people who sweat at nigh. Cases are zippered and zippers worked well and appear nicely sewn in and decent quality. At night, slept very well. I think this is a good product and like the price point a lo. Will be looking to get another set very soon!
