  • 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.

    A soft, non clingy top that fits perfectly!
    Color: Print 02, Size: X-Large
    This is such a versatile top . The sleeves are a perfect length. The material is high quality and the colors are so pretty. It launders well with no wrinkles. I will definitely be ordering more tops from WIHOLL. Great top at a great price.

    Nice quality casual shirt
    Color: Print 02, Size: Large
    I love this shirt! It was true to size, color and fit! I washed it in cold water and dried on permanent press. Put on a hanger immediately out of the dryer - no wrinkles! No shrinkage and no fade. Materials is light but is not see thru.

    Very flattering
    Color: Boho Print 03, Size: X-Large
    Great shirts! I have a large bust, and they still look great! They're comfortable and don't cling, and they're machine wash and tumble dry low. This is my third one, and I may buy more.

    Great feel and color
    Size: Medium, Color: Ocean Depths, Size: Medium, Color: Ocean Depths
    Absolutely love this tank top! The color is gorgeous and exactly like the pictures — super vibrant and flattering. The ribbed material feels soft but still has enough stretch to hug in all the right places. I also really like the built-in padding and racerback style because it makes it easy to wear without needing extra layers. The only thing I would mention is that it runs a little small, especially if you want a more relaxed fit. I’d recommend sizing up if you’re between sizes. Other than that, it’s a great basic top that looks cute dressed up or casual!

    Vibrant Racer Back Tank !!!
    Size: X-Small, Color: Hot Pink, Size: X-Small, Color: Hot Pink
    I purchased this Danysu V Neck Racer Back Tank Top for Women Padded Ribbed Long Tank Fitted Basic Cami Tops to wear under my off-shoulder top for an upcoming 80’s dance party, and it works perfectly for what I needed! The bright pink color really pops and adds the perfect retro accent to my outfit. I intentionally ordered the XS because I did not want it to fit loose under my top, and it definitely gives a snug, fitted look. The ribbed material is soft and stretchy, and the built-in padding is a nice bonus. I would recommend sizing up if you plan to wear it alone or if you are curvier, as the XS runs very tight. However, for layering under another top as I did, it worked out exactly the way I wanted. Super cute, flattering, and great for layering or workouts!
