Cloudline is a series of smart inline duct fans designed to quietly ventilate hydroponic grow rooms and tents, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets. Each features an inline mixed-flow design, meaning the duct fan can maintain airflow even in high static pressure applications. They contain an EC-motor with PWM-control 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. Comes with a smart controller featuring dynamic climate and time-based programming that can connect to one additional fan. 

The included controller features smart programming with the basic temperature and humidity 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 a variety of uses. Securely connect with the AC Infinity App via Bluetooth to access your fan remotely, unlock advance programs, set notifications, view historical climate charts, and export CSV data. This controller can connect to two AC Infinity fans with EC Motors including other CLOUDLINE fan sizes, and CLOUDRAY clip-on circulation fans.

Includes: one duct fan unit, one thermal controller, one corded thermal probe, two duct clamps, installation manual, and all necessary mounting hardware.

Really comfortable upgrade from my old desk chair
Color: Beige
My old desk chair had been getting pretty uncomfortable, so I decided to replace it with this white one. After using it for a few days, I can definitely say it’s been a really nice upgrade for my workspace. My old chair was starting to feel stiff and uncomfortable after sitting for a while. This one is a lot wider and softer, which I really appreciate. Sometimes I sit cross-legged when I’m working on my laptop, and this chair actually has enough space to do that comfortably. The flip-up arms are also really practical. When I’m not using them, I just flip them up and push the chair under my desk. My workspace feels a lot less cramped now. The wheels roll smoothly and the height adjustment was easy to set up. I also didn’t expect to use the side pockets much, but I’ve been keeping a notebook and my tablet there, which is actually pretty convenient. I mainly bought the white color because I wanted something simple for my home office, and it looks really clean in the room. After switching from my old chair, working at my desk has been a lot more comfortable. It’s been great for longer work sessions, and overall I’m really happy I decided to get this one.

Love the design, comfort and ease
Color: Grey, Color: Grey
Assembly was a breeze with the Amazon Basics Ergonomic Executive Office Desk Chair. The instructions were clear and easy to follow, and I had the chair put together quickly without any hassle. This simple setup made the whole experience even more satisfying from the start. In terms of comfort, the chair truly delivers. It provides excellent lumbar support, I assume it will make long hours at my desk much more enjoyable. The adjustable height feature lets me customize my seating position, and the flip-up armrests allow me to slide the chair neatly under my desk without worrying about damage. Overall, I couldn’t be happier with my purchase. The chair looks stunning in my office and perfectly complements the decor. It combines style, comfort, and practicality at a fantastic value, and I highly recommend it to anyone looking to upgrade their office chair. I love you so much that I ordered another one for my husband’s desk.

Very comfortable
Color: Grey
I’m not sure if I am just transitioning from a very uncomfortable office chair, but this one is extremely comfortable. Very good dynamic lumbar support that reminds you that it’s there. Only cons would be a low back (I am 6’5”) but I’m not laying my head back anyways. Also the seat length is a touch short for me but standard size really. Great bang for buck with an open box deal. Easy to assemble. TBD on durability.
