  • Designed to ventilate hydroponic grow rooms, transfer heating/cooling, cool AV closets, and exhaust odors.

  • Dynamic temperature and humidity programming, with timers, grow cycles, scheduling, minimum speed.

  • Remotely connect to the Wi-Fi app to access advance programs, view climate data, and set automation.

  • Mixed flow design combined with a PWM-controlled EC-motor for a truly quiet and energy efficient performance.

  • 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.

  • Smart Controller: CONTROLLER 69 PRO features smart programming that not only has basic temperature, humidity, and VPD triggers but also allows you to set dynamic fan speeds that would respond based on their changes. Go even further by setting a minimum speed that the fan will run at constantly and would only increase when triggered. Timer, cycle, and schedule modes add custom on-demand activation for various uses. Securely connect to the AC Infinity app through Wi-Fi to utilize automation capabilities from anywhere throughout the day. Access your fan remotely, unlock advance programs, set notifications, view historical climate charts, and export CSV data. This controller can connect to up to four UIS devices which includes products like the CLOUDLINE, CLOUDRAY, and IONFRAME Series. It can also connect to your favorite grow light and outlet device from outside the UIS platform using select adapters.

  • Quiet and Energy Efficient Design: Unlike common duct fans that use an AC motor which is loud and unmanageable, this duct fan features an EC motor that is controlled using PWM (Pulse Width Modulation). This technology enables motors to be able to run smoothly at extremely low RPM speeds without generating additional heat or noise. In addition, the duct fan uses a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, 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.

    BUY IT!!
    i am so glad i decided to purchase this product to help soothe a terrible sunburn! my skin was not only in pain but itching like crazy! this was the first product listed when i searched for collodial oatmeal lotion. at first the price kind of made have second thoughts but i decided to read the reviews & decided to take a chance. i was in dire need of relief & could not have been more pleased with the overnight delivery arriving at my door by 430am! upon arrival with a different item in my order, i noticed the pump was in an open position but looked past it as it could have happened during transport & being shooken around. to my surprise, it had not been used. i immediately began pumping for lotion to soothe my ailing skin! upon first dispensed product, the lotion did not appear too thin & water. it was not too thick either. it was the perfect consistency. the fragrance is so mild i barely noticed it. i smelled a hint of oatmeal. the lotion lathers well & does not feel sticky nor greasy. it does not leave a white cast or makes your skin look patchy. my skin felt relieved & soothed. my itchiness felt minimal after awhile. my skin felt very soft & supple. i did not feel like i had to keep reapplying product to feel well moisturized. but because i am fighting a sunburn, i did reapply product after 2-3hours to keep my skin calm. impressed with this product, i did feel the price was fair. the bottle is rather large so definitely getting what you pay for. packaging is well made too. doesnt feel super like cheap plastic. i appreciate the clean ingredients. it doesnt feel like it's full of chemicals. i did try the lotion on my legs & feet that were not suffering from sunburn & was impressed with how soft & nourished my skin felt after one application. if this product can my help my sunburn, im sure it can help eczema! i will definitely be repurchasing this product. 10/10 highly recommend.

    Why didn't I find this years ago?
    With my excema, I fought for over a decade to find a product that will help. This lotion is amazing. I put it on after showering. It goes on easy, it soaks in well and for a gal who is almost 60 my skin now looks nourished, healthy and like I'm in my 30s and soft. Using this with the balm, my excema patches are almost completely gone. Love this!
