Description
  • 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.

    Great Everyday Paper Plates for the Price
    Size: 100 Count (Pack of 1)
    For around six bucks, getting 100 microwave-safe paper plates like this is a really good deal. Also, they’re actually pretty good quality. They can hold a decent amount of food and they don’t get all soggy or start dripping through the bottom halfway through eating. The soak-proof part is legit. Another thing I liked is the design. The white and green looks simple but nice, and they honestly just look better than a lot of the random cheap paper plates out there. I’ve been using them pretty regularly for quick meals and throwing food in the microwave, and they’ve been really convenient. I will say, if the food is extremely hot, the bottom of the plate does warm up pretty fast since the plates are somewhat thin underneath. Sometimes using two plates instead of one helps with that. Aside from that though, they’ve been excellent. For the amount you get, the quality is genuinely solid and they’ve held up really well for everyday use. Amazon Basics definitely nailed these. 100% would recommend them.

    Worthwhile purchase
    Size: 300 Count
    Could be a tad more sturdy, maybe higher sides however still recommend; at the price/ quantity, the shear convenience, they burn easily in the firepit, and save on water/soap.

    Great value and super convenient for everyday use!
    Size: 300 Count
    exactly what I needed for busy days and quick cleanups. They’re sturdy enough for everyday meals like sandwiches, snacks, and even lighter hot foods without getting soggy or falling apart. I love the convenience of having such a large pack on hand — it lasts a long time and is perfect for families, parties, or meal prep days. The size is just right for most meals, and they stack easily for storage. For the price and quantity, it’s a great deal and saves so much time on dishwashing. Definitely a household staple I keep restocking!
