  • 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.

    Very helpful
    Size: 8 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
    This sunscreen is a fantastic value, especially since I managed to grab it while it was on sale. It applies smoothly without feeling overly greasy and provides solid protection for outdoor activities. It is definitely worth picking up if you can find a good deal on it, as it does exactly what it is supposed to do. I will be keeping an eye out for another sale so I can stock up for the rest of the summer.

    Great product
    I really like this sunscreen! It feels lightweight, absorbs quickly, and doesn’t leave my skin feeling greasy. The SPF 55 gives great protection, and it works well for everyday use. Great value for the price!

    Delivers what it promises
    I’m a fair skinned person who burns and freckles easily and in my 40’s. I also love being outside. I have worn spf on my face (and usually my hands) basically every day since I was 13 and because of that people always say I don’t look my age. Back then, only a 4 or 8 was available in face moisturizers, but I have always worn the highest that is recommended and usually face moisturizers are behind in meeting the recommendations so I have usually worn a full on sunscreen under my makeup. As the recommendations get higher it has been harder to find something that doesn’t look pasty, smell bad or interfere with makeup. I was using Eucerin spf 30 and Cera Ve spf 30 but I have wanted to increase spf to 50 because that is what is recommended now. I tried the Cera Ve spf 50 and was disappointed by how tacky it is and pasty it looks. I don’t even like wearing it alone to the beach because it’s so chalky white and sticky. Neutrogena healthy defense is alright but it has a scent and some chemicals that are not so good. It also is a pretty small bottle (1.7 oz) when you use it everyday on face and hands. But THIS product has blown me away with its affordability and quality. It IS sheer. Easily blends in and disappears quickly into skin. It’s completely odorless. It’s not tacky or greasy—you feel moisturized but not sticky. It performs under foundation even better than the Cera Ve 30. Now, this doesn’t have the extra ceramides and vitamins that does so I’ll still be using that when I feel extra dry like in winter, or I might mix the two moisturizers, but this Solimo reef safe sunscreen will definitely be my daily face and hand sunscreen in the spring, summer and early fall. These are the days I go straight from work to the garden or the beach. I can quickly reapply over my makeup before I leave the house again feel fully protected while I’m out.
