  • Designed to quietly ventilate grow tents, transfer heating/cooling to rooms, circulate fresh air, and cool AV closets.

  • Features a wired 10-speed fan controller; also compatible with all UIS controllers with intelligent programming.

  • PWM-controlled EC motor provides quiet and energy-efficient performance with minimal heat and noise.

  • Mixed flow design with stator blade and hydrodynamic wind circles enables airflow delivery in high resistance areas.

  • Duct Size: 4" | Dimensions: 6.9 x 11.9 x 7.4 in. | Airflow: 205 CFM | Noise: 28 dBA | Bearings: Dual Ball

  • Product Description: A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. It is built with a PWM-controlled EC motor for quiet and energy-efficient performance. The motor box containing the fan's impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Includes a smart controller with dynamic climate and time-based programming and can connect to multiple UIS devices. This product is a part of the UIS platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.

  • Precise Speed Controller: The speed controller enables you to set the duct fan's speed between ten speed levels to optimal noise and airflow levels in various environments. The precise airflow control is supported by the inline fan's cutting-edge EC motor that is precisely controlled using PWM (Pulse Width Modulation). This enables it to run smoothly at extremely low RPM speeds without generating motor noise. Also features backup memory that retains the last speed setting whenever power is cut off from the controller.

  • Quiet and Energy Efficient Design: This duct fan uses a mixed-flow design using a stator blade and dual hydrodynamic wind circles, enabling it to deliver airflow even in applications where air movement is restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids and performs well even in harsh environments.

  • Applications: This quiet duct fan system is popular in a variety of applications including cooling AV equipment rooms, closets, racks, and cabinets. Due to its low noise and advanced control features, it's also used in various air circulation and ventilation projects including hydroponic grow rooms and tents, exhausting bathrooms and attics, and other installations.

    Not quite indestructible, but closer than other toys
    Size: Large 10", Style: Rubber Dog Toy
    We have a German Shepherd who chews through pretty much any toy you give him. He has very strong, destructive jaws. And, being very smart, he will find the weak point in a toy and go after it almost obsessively. He'll work tirelessly trying to chew it into submission. I don't know how many toys we've gone through. We even did the subscription where they send you indestructible toys every month. Usually, they wouldn't make it until the next shipment. Any of them. And they sent three or four in the box. Anyway, this is our second one of these. He does destroy it, but he's had this one for three months or better and it's just now really showing signs of deterioration. We'll be replacing it soon, but I'm very impressed compared to the countless other toys we've bought over the years.

    Toy Not Safe For Chewers
    Size: Medium 8", Style: Rubber Dog Toy, Size: Medium 8", Style: Rubber Dog Toy
    We bought this tire toy for our puppy for Christmas. It was advertised as a natural rubber dog toy and implied to be durable. It lasted less than two hours. Our puppy was able to chew off small pieces of the rubber and swallowed some of the bits, which made her extremely sick. She ended up vomiting after ingesting pieces of this toy. I would not recommend this toy, it is not safe especially for dogs that like to chew.

    Nice big tire toy
    Size: Large 10", Style: Rubber Dog Toy
    Our dog has had a tire toy about the same size as this one for 2 years, but it's finally been worn down from his love and zest for it along with weather. When I saw this one, I got excited! Great size for our 80lb 3yo pittie and pretty tough too, although, it's beginning to show signs of wear in only 3 weeks of him playing with it. It's not nearly as rugged as his old rubber tire. We'll have to see how long it actually lasts before I say the price was worth it or not.
