Most important from
9985 reviews
The AC Infinity CLOUDLINE PRO T6 is a well-rounded 6-inch inline duct fan designed primarily for ventilation in hydroponic grow rooms, heating and cooling systems, and even AV closets. One of its standout features is the combination of a PWM-controlled EC motor and a mixed flow design, which ensures a quiet operation at just 32 dBA, making it suitable for environments where noise might be a concern.
With an impressive airflow of 402 CFM, this fan does a fantastic job of moving air efficiently, which is crucial for maintaining a stable and healthy growing environment. The product also shines in flexibility, offering temperature and humidity programming along with scheduling and automation, all accessible via a user-friendly WiFi app. This feature is particularly beneficial for those managing complex grow cycles, as it allows for precise control over the environment.
On the flip side, while the fan is lauded for its quiet performance and efficiency, some users may find the setup of the app and advanced features a bit complicated at first. Additionally, the weight of 7.02 pounds and dimensions might pose slight challenges in installation, especially in tight spaces. However, once set up, the durable build quality and dual ball bearings promise longevity and reliable performance.

Most important from
536 reviews
The VIVOSUN Smart Air Filtration PRO S6 Kit 6" is a comprehensive solution for efficient air circulation and ventilation, especially designed for grow tents and hydroponic systems. One of its standout strengths is the high airflow rate of 405 CFM, which ensures it can handle sizable ventilation tasks effectively. Additionally, it operates at a relatively quiet 45 dB, making it a good choice for indoor environments where noise can be a concern.
The inclusion of the GrowHub E42A controller adds a layer of intelligence with its precise fan speed and airflow controls, along with WiFi connectivity for remote management. This feature is particularly beneficial for users who need to monitor and adjust their grow environment on the go. The premium RC 412 Australian Virgin charcoal filter is another positive, offering excellent odor control and ensuring a cleaner air environment.
The build quality of the kit is also commendable, with durable aluminum ducting and heavy-duty stainless steel clamps that prevent air leaks. Installation and maintenance are made easier with the included mounting hardware, though the weight of 20.7 pounds might be on the heavier side for some setups. This kit is an efficient and intelligently controlled option for those needing robust air filtration and ventilation in a grow tent or similar setup, balancing good build quality and performance with convenient remote control capabilities.
