Product Description
A grow tent air filtration system with all the inline components you need to ventilate your grow space. By assembling these essential pieces, this package will help you quickly start your grow build and eliminate the guesswork of purchasing them individually. This kit features the CLOUDLINE inline duct fan that can deliver a powerful yet quieter performance. It is controlled by the first AI-powered controller for self-automating programming with anticipatory insight that ensures exact percentage output. Paired with a rust-resistant carbon filter with a gunmetal finish using Australian virgin charcoal to block odors from seeping out of your grow tent. These ducting components are connected by flexible ducting with four layers of protection to direct airflow properly. Accessories include duct clamps, prefilter cloth, rope clip hangers, and hanging straps to complete the installation. 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.
Intelligent Programming
CONTROLLER AI+ observes your grow space, pairing with the inline fan to make environmental adjustments and ensure its stability. Going beyond on/off triggering and timer programming, it is always learning, analyzing previous results to avoid over or undershooting output levels and better optimize your climate. Connect this controller to the AC Infinity app to select between two AI inputs for quick AI-generated presets that adjust automatically or fine-tuned control for greater customization. You can also get access to helpful grow guides, recipes, articles, video tutorials, and chatbot assistance that will equip you with the knowledge to improve how you grow.
Quiet and Energy-Efficient Design
The included CLOUDLINE Series inline fan features a PWM-controlled EC motor, enabling smooth operation at low RPM speeds with no additional heat or noise. It achieves high-performance airflow fit for grow tents thanks to its mixed-flow design and its use of stator blades and hydrodynamic wind circles. Dual ball bearings give this inline fan a 67,000-hour lifespan, which is backed by its IP-44 sealing that resists dust and splashing liquids.
Premium Grade Carbon
The duct carbon filter effectively blocks unwanted odors and chemicals using its bed of premium Australian charcoal. Featuring a 1200+ IAV rating, the activated carbon supports clean airflow more efficiently, thanks to its increased adsorption rate and extended life rating. The filter’s durable steel mesh body is protected by a powder-coated gunmetal finish to defend against rust and corrosion in high-humidity growing environments.
